Updated June 2026 — refreshed with current research on the cortisol awakening response, hydration and cognition, and UK magnesium intake data, plus a new FAQ. Originally published 2021.
Quick Answer:
Yes, most UK adults should supplement magnesium. Around 10-15% of UK adults fall below adequate intake levels. Magnesium bisglycinate is the most effective form: 90% absorption vs 4% for magnesium oxide, gentle on digestion, no laxative effect. Take 200-400mg daily with food.
Do you actually need to supplement magnesium?
For most UK adults, probably yes.
Data from the UK National Diet and Nutrition Survey (NDNS) shows that a substantial number of adults consume less magnesium than the recommended nutrient intake — particularly women aged 19–64 and adults over 65. Around 10-15% of UK adults fall below the Lower Reference Nutrient Intake, meaning their intake is very likely inadequate.
Magnesium drives over 300 enzymatic reactions in the body: energy production, muscle and nerve function, sleep regulation, blood pressure, and blood sugar control.
The signs of running low show up as everyday things people tend to blame on stress: poor sleep, muscle cramps, low energy, low mood, irritability.
But here’s what most people don’t realise: the form matters more than the number on the label.
Most magnesium supplements don’t work
Walk into any health shop and you’ll see dozens of magnesium products. Most of them are citrate or oxide.
Magnesium citrate is chosen because it’s cheap to produce. The problem: it pulls water into the bowel, which means loose stools or digestive discomfort for a lot of people. Studies show it’s essentially a mild laxative.
Magnesium oxide is even cheaper. It also has the worst absorption rate of any supplemental form — as low as 4%. So you’re paying for magnesium that’s mostly leaving your body unabsorbed.
Both are chosen for cost, not for effectiveness.
Comparison: Magnesium Forms by Absorption Rate
| Form | Absorption Rate | Digestive Tolerance | Best For |
|---|---|---|---|
| Magnesium Oxide | ~4% | Poor (laxative effect) | Constipation relief only |
| Magnesium Citrate | 25-30% | Moderate (loose stools common) | Short-term use |
| Magnesium Bisglycinate | Up to 90% | Excellent (no laxative effect) | Daily supplementation |
Magnesium bisglycinate: the form that actually works
Magnesium bisglycinate (also called magnesium glycinate) is chelated — meaning it’s bound to the amino acid glycine. This makes two things happen:
1. It’s gentle on the gut. Unlike citrate, it doesn’t draw water into the bowel. Magnesium glycinate is widely considered one of the gentlest magnesium forms on the digestive system, with a significantly lower risk of laxative effects. No digestive issues.
2. It’s highly absorbable. The chelation allows it to cross the intestinal wall efficiently and actually get into cells where magnesium does its work. Research indicates magnesium glycinate absorption rates can reach 90% bioavailability, significantly higher than the 4% absorption seen with magnesium oxide.
It costs more to produce, which is why most brands don’t use it. But if you’re supplementing magnesium, it’s the only form worth taking consistently.

Signs you need magnesium supplementation
If you experience any of the following regularly, there’s a good chance you’re running low:
- Poor sleep quality or difficulty staying asleep — magnesium regulates GABA receptors for sleep
- Muscle cramps, twitches, or tension — magnesium controls muscle contraction and relaxation
- Low energy that doesn’t improve with rest — magnesium is required for ATP (cellular energy) production
- Irritability or low mood — magnesium supports neurotransmitter function
- Brain fog or difficulty concentrating — magnesium affects cognitive performance
You deplete magnesium faster if you:
- Train hard or sweat regularly (athletes lose magnesium through sweat)
- Are under chronic stress (stress hormones increase magnesium excretion)
- Drink alcohol regularly (alcohol reduces magnesium absorption)
- Take certain medications — PPIs (proton pump inhibitors) or diuretics
How much magnesium should I take?
The UK Reference Nutrient Intake (RNI) for magnesium is:
- 300mg per day for men
- 270mg per day for women
If you’re not hitting 400mg+ of magnesium daily from food (dark leafy greens, nuts, seeds, whole grains, legumes), supplementing makes sense.
Recommended supplementation dose: 200-400mg of magnesium bisglycinate per day, taken with food. Most people notice improvements in sleep quality within a week or two. For muscle cramps or recovery, the effect is often faster.
Note on timing:
Take magnesium bisglycinate in the evening 1-2 hours before bed if using it for sleep support. For general supplementation, any time with food works — split the dose (morning and evening) if taking 400mg+ daily.
Key takeaways: Magnesium supplementation in the UK
- 10-15% of UK adults fall below adequate magnesium intake according to NDNS data
- Magnesium bisglycinate has up to 90% absorption vs 4% for magnesium oxide
- Bisglycinate is gentle on digestion — no laxative effect unlike citrate or oxide
- Recommended dose: 200-400mg daily with food
- Benefits appear within 1-2 weeks for most people (sleep, muscle function)
- Look for third-party tested products (Informed Sport certification)

Frequently Asked Questions
What is the best form of magnesium to take in the UK?
Magnesium bisglycinate is the best form for daily supplementation. It has the highest absorption rate (up to 90%), is gentle on the digestive system, and doesn’t cause laxative effects. Avoid magnesium oxide (only 4% absorption) and citrate (causes digestive issues).
How long does it take for magnesium bisglycinate to work?
Most people notice improvements in sleep quality within 1-2 weeks of consistent supplementation. Effects on muscle cramps and recovery can appear within 3-7 days. Full tissue saturation takes 4-6 weeks of daily supplementation.
Can I take magnesium bisglycinate every day?
Yes. Magnesium bisglycinate is safe for long-term daily use at doses of 200-400mg. It’s well-tolerated with minimal side effects, unlike other forms. Take it with food for optimal absorption.
What’s the difference between magnesium glycinate and bisglycinate?
Magnesium bisglycinate has two glycine molecules bound to one magnesium ion (1:2 ratio), while glycinate has one (1:1 ratio). Bisglycinate is slightly more stable during digestion but both are highly absorbable and gentle. The terms are often used interchangeably.
Does magnesium bisglycinate cause diarrhea?
No. Unlike magnesium citrate and oxide, magnesium bisglycinate does not have a laxative effect. It’s chelated with glycine, which prevents the osmotic water-drawing effect that causes loose stools with other forms.
Should I take magnesium in the morning or at night?
For sleep support, take magnesium bisglycinate 1-2 hours before bed. For general supplementation, any time with food works. If taking 400mg+ daily, split the dose between morning and evening for better absorption.
What foods interact with magnesium absorption?
High-calcium meals can compete with magnesium for absorption. Space them out by 2-3 hours if possible. Magnesium bisglycinate is less affected by this interaction than other forms due to its chelated structure.
Are most people in the UK deficient in magnesium?
According to UK National Diet and Nutrition Survey data, 10-15% of UK adults fall below the Lower Reference Nutrient Intake (deficiency threshold). Many more consume less than the recommended 300mg (men) or 270mg (women) daily, putting them at risk of insufficiency.

Chlorella is a bright green algae dense in nutrients. It is considered a “superfood” because it is high in protein, iron, dietary fibre, B vitamins and complex carbohydrates. In this article, Human Performance Hub deep dives into everything chlorella related, from its many health benefits to dosage guidelines and most commonly asked questions. So, what kinds of benefits can you expect from taking chlorella tablets?
Chlorella has an extremely impressive nutritional profile. In particular, it supports:
- Immune system
- Weight management
- Cholesterol balance
- Blood pressure/sugar levels
- Aerobic endurance
On top of this, chlorella also binds to heavy metals, acts as an antioxidant and helps with respiratory diseases.
Keep reading to find out more about this freshwater algae.
What Is Chlorella?
According to BBC good food, ‘chlorella is a single-cell, blue-green freshwater algae with a rich colour due to its high concentration of chlorophyll.’ One teaspoon of chlorella in powder form contains:
- 11Kcal / 44KJ
- 1.8g Protein
- 0.1g Fat
- 0.5g Carbohydrate
- 3.4mcg Iodine
- 6.6mcg Vitamin B12
Whilst there are over 30 different species of chlorella, the most commonly researched forms include Chlorella vulgaris and Chlorella pyrenoidosa. Chlorella has a hard cell wall which humans cannot digest. As a result, it must be taken as a supplement to reap the benefits. Available in capsule, tablet, powder and extract form, studies have shown that Chlorella can have many health benefits.

Health Benefits of Taking Chlorella
Below, we’ve outlined the main advantages of taking chlorella tablets as a health supplement:
Nutritious
Referred to as a “super food” by many because of its impressive nutritional profile, Chlorella contains:
- Protein – Chlorella is 50-60% protein. In fact, it is a complete protein source, which means it contains all nine essential amino acids.
- Vitamin B12 – Some chlorella varieties may also contain vitamin B12 however, further research is required.
- Iron & Vitamin C – Depending on the supplement, Chlorella can provide anywhere from 6–40% of your daily need of iron. It’s also an excellent source of vitamin C, which helps you absorb iron.
- Antioxidants – These small green cells provide a wide range of antioxidants.
- Other vitamins & minerals – Chlorella provides small amounts of magnesium, zinc, copper, potassium, calcium, folic acid and other B vitamins.
- Omega-3s – Like other algae, chlorella contains some omega-3s. In fact, just 3 grams of chlorella delivers 100mg of omega-3s.
- Fibre – In large amounts, chlorella can be a good source of fibre. However, bear in mind that most supplements don’t provide even 1 gram of fibre per dose.

Binds To Heavy Metals
Often marked for its ‘detox’ benefits, animal studies suggest that chlorella is effective at binding with heavy metals and other harmful compounds. Heavy metals include some elements that are essential in small quantities, such as iron and copper; however, these can be toxic in large quantities.
Whilst it is rare for humans to experience such high levels of heavy metal toxicity, people can get exposed to heavy metals through pollution or certain jobs such as mining.
On top of its ability to weaken the heavy metal toxicity of the liver, brain and kidneys, chlorella has also been shown to help lower the amount of other harmful chemicals that are sometimes found in food. This includes dioxin, a hormone disruptor that can contaminate animals in the food supply.
Based on this evidence, it seems that chlorella could help enhance your body’s natural ability to clear toxins.
Immune System
Whilst evidence is limited so far, chlorella has been shown to enhance the immune response in both animal and human studies. In one small study, men were seen to produce more immune antibodies when they were supplementing with chlorella for a four-week period. Similarly, in another small study, chlorella supplements showed an increase in immune cells called ‘natural killer’ cells. These are extremely important in our fight against cancer and microbial infection.
Nevertheless, findings have been mixed, with some studies showing little to no effect. For example, one study found that chlorella supplements enhanced immune function in participants aged 50-55, but not those over 55. Consequently, it’s fair to argue that chlorella may have immune-boosting effects in some populations and age groups, but not in all.
Weight Management
There has been some limited evidence from animal studies to suggest that chlorella can help with weight loss by improving fat metabolism and blood sugar regulation. This statement is further supported by The Journal of Medicinal Food, which reported that chlorella resulted in noticeable reductions in body fat percentage, serum total cholesterol and fasting blood glucose levels over a 16-week trial.
Cholesterol Balance
Several studies indicate a potential role for chlorella in helping balance cholesterol levels. In particular, studies have shown that taking 5-10 grams of chlorella daily lowered total and LDL cholesterol and triglycerides in people with high blood pressure or elevated cholesterol. This may be down to the nutrients found in chlorella, such as vitamin B3 (Niacin), carotenoids, fibre and protective antioxidants.
Acts as an Antioxidant
Chlorella contains several compounds that are considered antioxidants, including:
- Chlorophyll
- Vitamin C
- Beta-carotene
- Lycopene
- Lutein
These antioxidants can help fight many chronic diseases. Some actually reduce the production of advanced glycation end products, which drive many of the complications of diabetes.
Blood Pressure Management
Chlorella supplements could help promote heart and kidney health, both of which are essential for normal blood pressure. In one human study, daily supplementation of chlorella helped reduce high blood pressure while another small study reported less stiffness in the arteries, a factor that directly contributes to high blood pressure.
Blood Sugar Levels
Some research shows that chlorella may help lower blood sugar levels. One study discovered that taking chlorella for 12 weeks lowered fasting blood sugar levels in both healthy individuals and those at high risk of lifestyle-related diseases. On top of this, studies have shown that supplementing with chlorella improves blood sugar control and increases insulin sensitivity in patients with non-alcoholic fatty liver disease.
Respiratory Diseases
Managing respiratory diseases such as asthma and chronic obstructive pulmonary disease often requires controlling inflammation. Fortunately, chlorella has some components that can help reduce inflammation, including its antioxidants. In fact, one study found that chlorella supplements improved antioxidant status in COPD patients.
Aerobic Endurance
There has only been one study conducted so far surrounding chlorella’s effect on aerobic endurance, but it showed a positive result. Researchers gave a group of young adults six grams of chlorella or a placebo daily for four weeks. At the end of the study, the chlorella group showed a significantly improved ability to saturate their lungs with oxygen, which is a measure of endurance. Alternatively, the placebo group did not experience any changes in endurance. This effect may be due to chlorella’s branched-chain amino acid content.
*Please Note – Whilst there are many studies to support the health benefits of chlorella, further evidence is required to fully support these statements.
How Does Chlorella Support Oxygen Delivery and Aerobic Performance?
While chlorella is a natural source of plant-based protein and contains branched-chain amino acids (BCAAs), the improvements in aerobic performance sometimes reported in the literature are unlikely to be driven by protein intake alone, particularly at typical serving sizes (1–3g per day).
The more physiologically supported mechanism relates to vascular function and nitric oxide (NO) production.
Chlorella contains bioactive compounds including arginine, antioxidants, chlorophyll derivatives, and phytonutrients that may support endothelial health. Improved endothelial function can enhance nitric oxide bioavailability, leading to vasodilation (widening of blood vessels). This process may improve blood flow, oxygen delivery, and oxygen utilisation during exercise.
Several human studies have demonstrated that chlorella supplementation may:
-
Improve arterial stiffness
-
Support vascular elasticity
-
Enhance systemic circulation
-
Improve markers of cardiovascular efficiency
Improved oxygen transport is therefore likely a secondary effect of enhanced vascular function, rather than a direct effect on lung tissue or respiratory capacity.
This aligns with broader research on nitrate-rich and polyphenol-rich plant foods (such as beetroot, spinach, pomegranate, and dark chocolate), which enhance exercise efficiency via nitric oxide pathways.
Chlorella should therefore be understood as a whole-food microalgae providing multiple supportive nutrients, rather than a high-dose protein intervention for endurance enhancement.

Other Potential Benefits
Some other possible benefits of chlorella include:
- Promotes eye health – Chlorella contains lutein and zeaxanthin, two carotenoids that protect the eye and lower the risk of macular degeneration.
- Supports liver health – Chlorella supplements have been shown to improve markers of liver health in people with liver disease.
- Improved digestion – Lots of research claims that chlorella eases digestion and reduces bloating.
- Relieves PMS – Anecdotal evidence says that chlorella can relieve symptoms of premenstrual syndrome (PMS).
Please bear in mind that there’s little research to support these claims.
How To Supplement With Chlorella
At Human Performance Hub, the recommended starting dose is 3 capsules of chlorella per day with a meal, which can build into 10 caps x 3 times per day. This would however, depend on how much support your body needs. Some individuals may require more, which is why you should always consult your doctor to get an individual recommendation before you begin taking chlorella tablets.
Is Chlorella Safe For Everyone?
Generally, chlorella is recognised as safe if used in the short-term, however it can cause some side effects for people in high-risk groups. This includes individuals who are:
- Pregnant
- Breastfeeding
- Iodine sensitive
- Allergic to mould
It can also affect those with a weakened immune system or individuals with autoimmune conditions. Some of the possible side effects include diarrhoea, nausea and stomach cramps. There have also been some reported cases of allergic reactions and an increase in sun sensitivity. However, it’s important to bear in mind that these side effects will not necessarily be present in everyone.

Chlorella FAQs
What Does Chlorella Do To The Brain?
Chlorella supplies your brain with B vitamins, vitamins A, C, D and E. It also provides minerals like calcium, iron, phosphorus, magnesium and zinc, all of which are essential in keeping your brain healthy and functioning.
Does Chlorella Make You Look Younger?
Yes. Chlorella can significantly raise the body’s antioxidant levels, which in turn helps to protect against damage caused by free radicals, a problem exacerbated by increasing levels of pollution and exposure to the sun. In one Korean study, smokers who took chlorella tablets daily had 44% more anti-aging vitamin C in their blood than those who took a placebo. Thanks to its antioxidant properties, vitamin C plays a vital role in collagen synthesis, which helps protect and improve skin health.
Does Chlorella Affect Sleep?
Yes. It might seem bizarre but an algae supplement like chlorella that contains high amounts of B vitamins, calcium, magnesium, tryptophan and omega-3 fatty acids can contribute to quality sleep.
Can You Take Chlorella Everyday?
Yes. The recommended starting dose is 3 capsules of chlorella per day with a meal, which can build into 10 caps x 3 times per day. Remember that this dose will vary depending on the individual.
How Long Does It Take To See Results From Chlorella?
According to the Journal of Medicinal Food, studies discovered that individuals started showing noticeable results after taking chlorella for 3 months.
What To Avoid When Taking Chlorella?
It’s advisable to avoid taking chlorella if you are taking any medication that decreases the immune system, as well as blood thinners such as warfarin.
When Is The Best Time To Take Chlorella?
At Human Performance Hub, we recommend that you spread your dosage of chlorella throughout the day for consistent nutrient absorption. Ideally, you should take chlorella first thing in the morning and before bedtime. Taking chlorella with food can also help you avoid initial digestive side effects as your body adjusts.
What Is The Difference Between Chlorella and Spirulina?
Chlorella and spirulina are the most popular algae supplements on the market. While both have an impressive nutritional profile, they do have some key differences. Chlorella is higher in fat and calories while spirulina is lower in calories and contains high amounts of riboflavin, thiamine, iron and copper.
Key differences:
| Chlorella | Spirulina |
| Freshwater algae | Saltwater algae |
| Higher levels of omega-3 fatty acids | Higher in protein |
| Higher in vitamin A, iron and magnesium | Contains more copper |

Key Takeaway: Taurine supports testosterone production by acting on the hypothalamus-pituitary-testis (HPT) axis and directly stimulating Leydig cells. Recent 2024 research confirms taurine significantly elevates DHT (dihydrotestosterone) levels and protects testosterone molecules from oxidative stress.

Common questions about taurine and testosterone
How Taurine Increases Testosterone
Taurine supports testosterone production through two primary mechanisms:
1. The HPT Axis Regulation
Taurine regulates the hypothalamus-pituitary-testis (HPT) axis, your body’s central hormonal control system. Here’s how it works:
- Hypothalamus: Taurine stabilises GnRH (gonadotropin-releasing hormone) secretion through negative feedback between neurons
- Pituitary Gland: Stimulates luteinising hormone (LH) secretion, which signals the testes to produce testosterone
- Testes: LH triggers Leydig cells to synthesise and release testosterone
2. Direct Action on Leydig Cells
Beyond the HPT axis, taurine acts directly on Leydig cells in the testes. Research shows that taurine:
- Increases testosterone synthesis by enhancing autophagy (cellular cleanup) and inhibiting apoptosis (cell death)
- Protects testosterone molecules from oxidative stress
- Enhances the activity of key steroidogenesis enzymes (StAR, 3-HSD, 17β-HSD)
💡 Fun Fact: Taurine gets its name from the Latin word “taurus” (bull) because it was first isolated from ox bile in 1827. Despite the name, taurine does NOT come from bull urine or semen—that’s a persistent myth!
Latest Research (2024-2025)
Taurine Elevates DHT and Hormone Levels (2024)
A groundbreaking 2024 study published in PMC demonstrated that taurine significantly increases dihydrotestosterone (DHT) and dihydroprogesterone (DHP) levels in human cells.
Study Details
- Concentration tested: 0.25-1 mg/mL
- Results: Significant DHT elevation (p < 0.001)
- Mechanism: Enhanced miRNA-181 and miRNA-21 expression
- Application: Potential hormone therapy for neurodegenerative conditions
Key Findings
The study revealed that taurine’s hormonal effects are dose-dependent. Higher concentrations (0.75-1 mg/mL) produced the most significant increases in DHT and DHP hormones, suggesting taurine plays a regulatory role in gene expression associated with hormonal protection.
Sex and Gender Differences in Taurine Response (2025)
A comprehensive 2025 review in PMC highlighted that taurine research has historically focused on males, creating a significant knowledge gap. Key findings:
- In women, taurine (3g/day for 4 weeks) reduced homocysteine levels by 11%, supporting cardiovascular and metabolic health
- Taurine’s effects on oestrogen metabolism and testosterone regulation differ between sexes
- More research is needed to establish sex-specific dosage recommendations
⚠️ Important Note: A June 2025 NIH study challenged taurine’s role as an “aging biomarker,” finding that circulating taurine levels often increase with age in humans. However, this doesn’t diminish taurine’s proven benefits for testosterone support, cardiovascular health, and muscle function.
Why Do People Take Taurine?
Beyond testosterone support, taurine is essential for multiple body functions:
Cardiovascular Function
Regulates blood pressure, controls calcium levels in cells, and supports heart muscle function.
Nervous System
Supports neurotransmitter function and protects against neurodegeneration.
Immune System
Enhances immune cell function and provides anti-inflammatory protection.
Cellular Hydration
Maintains electrolyte balance and cellular water content for optimal function.
Taurine also provides powerful antioxidant and anti-inflammatory properties, protecting your cells from oxidative damage.
🔬 Serious Fact: Your body produces taurine naturally, but production declines with age and under stress. Dietary sources and supplementation become increasingly important for maintaining optimal levels, especially for testosterone support and muscle function.
How to Take Taurine for Testosterone
Dietary Sources of Taurine
Taurine is naturally found in animal-based foods:
High Taurine Foods
- Shellfish: Scallops, mussels, clams
- Fish: Tuna, salmon, mackerel
- Meat: Beef, pork, lamb
- Poultry: Dark meat chicken, turkey
Lower Taurine Sources
- Dairy: Milk, cheese (small amounts)
- Plant Foods: Minimal to none
- Note: Vegetarians and vegans should consider supplementation
Supplementation Guidelines
Recommended Dosage for Testosterone Support:
- Starting dose: 1 gram (1,000 mg) per day
- Optimal range: 3-5 grams daily for hormonal and performance benefits
- Timing: Can be taken any time of day, with or without food
- Consistency: Daily supplementation for 4-8 weeks to see full hormonal effects
Here at Human Performance Hub, we provide high-quality Taurine supplements that deliver 1g of pure taurine per capsule.
5 Additional Benefits of Taurine
Beyond testosterone support, taurine offers comprehensive health benefits:
1. Lowers Stress Levels
Taurine increases glycine and GABA to calm the brain and ease anxiety. Studies show it has antidepressant effects and can improve learning ability and memory. It also protects the brain by reducing the harmful effects of excess glutamate.
2. Protects Cardiovascular Health
Research demonstrates taurine’s anti-inflammatory effects and blood pressure regulation. At therapeutic levels, taurine protects the heart from coronary heart disease and helps those with heart conditions exercise more effectively.
Clinical Evidence: A 2025 meta-analysis of 808 participants found that taurine reduces heart rate, systolic blood pressure, and diastolic blood pressure in a dose-dependent manner.
3. Supports Brain Function
Taurine protects the brain and supports overall cognitive function. As taurine levels decrease with age, supplementation can increase long-term memory and fend off neurodegenerative conditions. Studies suggest taurine may reduce symptoms of Alzheimer’s disease and improve overall memory.
4. Enhances Performance and Recovery
As an essential amino acid, taurine can:
- Increase muscle recovery after workouts and reduce soreness
- Improve performance by enhancing anaerobic and aerobic metabolism
- Boost endurance and strength during training
5. Improves Fat Burning
Evidence shows taurine can increase lipid metabolism during exercise, leading to enhanced fat burning. This is ideal for athletes maintaining a lean physique. Taurine also removes waste products that lead to fatigue and muscle burn, protecting muscles from oxidative stress.
💪 Performance Tip: Successive taurine treatment (daily supplementation) provides significantly better results than single-dose treatment for improving sperm motility, sperm count, and testicular antioxidant capacity.
Is It Safe to Take Taurine Daily?
Yes. According to the best available evidence, taurine has no negative side effects when supplemented appropriately.
Evidence-Based Safety Guidelines
Safe Daily Doses
- 2019 Research: Up to 3 grams per day
- EFSA Guidelines (2012): Up to 6 grams per day
- Clinical Studies: 3-5 grams daily with no adverse effects
Long-Term Use
Numerous studies confirm taurine’s safety for continuous daily supplementation. No common side effects have been identified in clinical research to date.
🔬 Serious Fact: While there’s insufficient evidence to call taurine the “best supplement” for any single purpose, customer satisfaction data shows 98% would recommend taurine, 97% report better sleep, 77% fall asleep faster, and 78% wake less frequently throughout the night.
Frequently Asked Questions
Does taurine increase testosterone levels?
Yes, taurine supports testosterone production by regulating hormone release from the hypothalamus and pituitary gland (the HPT axis). It also acts directly on Leydig cells in the testes to increase testosterone synthesis. Research from 2024 confirms taurine’s role in elevating dihydrotestosterone (DHT) levels.
How much taurine should I take for testosterone support?
The recommended dose ranges from 3-5 grams daily for healthy testosterone function. Start with 1 gram per day and increase gradually. Studies show consistent benefits at 3g/day with no adverse effects reported.
How long does it take for taurine to affect testosterone?
Most users notice improvements in energy and muscle strength within 2-4 weeks of consistent supplementation. Hormonal changes occur gradually as taurine supports the HPT axis function over time.
Can women take taurine for hormonal support?
Yes. In women, taurine helps regulate oestrogen metabolism and detoxification by raising testosterone levels in androgen receptors. A 2025 study confirmed taurine’s benefits for hormonal balance in both men and women.
Are there any side effects of taurine supplementation?
Research has not identified any common side effects from taurine supplementation at recommended doses (3-6 grams daily). Taurine is considered safe for long-term daily use according to EFSA guidelines.
Can I get enough taurine from food alone?
While taurine is found in meat, fish, and dairy, supplementation ensures optimal levels for testosterone support and performance benefits. Vegetarians and vegans especially benefit from supplementation as plant foods contain minimal taurine.

So, does potassium calm nerves?
Whilst individual responses vary, potassium has been shown to calm nerves, anxiety, and depression. It does this by regulating a range of hormones produced as a result of stress, like cortisol and adrenaline. Studies have shown that potassium activates neurons involved in positive thoughts and feelings.
Read on to learn more about how potassium helps with nerves and the many more benefits of consuming this mineral.
Can Potassium Help With Nerves?
Yes. Ingesting potassium assists with regulating a variety of hormones in your body, especially those produced as a result of stress, such as cortisol and adrenaline. This helps reduce any feelings of anxiousness or tension that you may be experiencing.
Latest Research (2024-2025)
Recent clinical studies have provided compelling new evidence for potassium’s role in mental health:
A 2024 case study published in BMC Psychiatry documented the rapid treatment of severe depression with potassium supplementation. The patient experienced significant improvement within just one week, with complete resolution of anxiety and depression symptoms by week four. This groundbreaking case suggests that relative potassium deficiency in emotional regulation brain regions may contribute to mood disorders.
Additionally, a 2023 population study found that individuals with lower potassium intake had 3.7 times higher odds of experiencing co-existent anxiety and depression compared to those with adequate potassium levels.
Potassium and Anxiety
A common cause of anxiety is having a poor diet. When you lack a particular vitamin or mineral, your system can be hugely affected. In relation to potassium, low levels can cause mental fatigue, stress, and anxiety. The best way to overcome this is to eat a well-balanced diet with plenty of natural foods. This can help you overcome your anxiety.
Potassium and Depression
Low potassium levels have also been associated with an increase in mood disturbances and depression. A 2008 study published in the British Journal of Nutrition examined the relationship between potassium and mood. They found that a high-potassium diet helped to relieve symptoms of depression and tension. These results show that potassium is extremely effective in generally uplifting our mood.
What Is Potassium and How Does It Work in the Body?
Potassium is a mineral that every cell in your body needs. It helps just about everything in your body, including your brain, nerves, kidneys, heart, and other organs. As an electrolyte, potassium helps to manage how much water is in your body. It also helps to keep up your body’s electrical system whilst moving nutrients into your cells and taking waste out. Additionally, potassium keeps your body’s sodium levels in check.
The Science Behind Potassium and Nerve Function
Research published in 2024 reveals that potassium channels in the brain play a crucial role in regulating neuronal activity linked to mood. Potassium channel openers have shown antidepressant effects in clinical trials, with significant improvements in depressive symptoms and anhedonia (inability to feel pleasure).
Other Health Benefits of Potassium
Potassium is incredibly important because it helps our hearts, kidneys, and other organs work normally. Here is a list of the many benefits of potassium:
1. Increases Brain Function
High potassium levels act as a vasodilator, allowing blood to move more easily through the blood vessels. This blood carries oxygen to the brain, which increases your activity levels and cognitive abilities.
2. Normalises Blood Pressure
Potassium works to balance blood pressure and counteract the effects sodium has on raising it. This helps to reduce the risk of hypertension and heart disease. Recent 2025 research shows potassium supplementation can reduce mean arterial pressure by up to 20% in certain hypertension models.
3. Increases Metabolism
Potassium helps your body extract nutrients from what you eat and helps to break down and process these nutrients. It also plays an important role in synthesising protein and metabolising carbohydrates.
4. Improves Muscular & Heart Health
A diet that is adequate in potassium helps maintain strong muscles. Potassium helps muscle tissue grow properly and is also involved in the electrical signals sent by muscles. This lets them contract properly.
Potassium is also important for a healthy heart, as its movement in and out of cells helps maintain a regular heartbeat.
5. Aids Nervous System
Your nerves send messages to various parts of your body. Potassium helps to make the transportation of these signals easier and more efficient. This improved functioning helps your muscles perform better.
6. Helps Prevent Kidney Stones
Kidney stones are ‘hard stones’ made from calcium in your urine. One form of potassium, potassium citrate, binds up this calcium. This helps prevent crystals from forming that could become kidney stones.
7. Helps Regulate Serotonin
A study in the journal Nature Neuroscience investigated the role of potassium in the regulation of serotonin, the neurotransmitter primarily targeted by antidepressants. The results showed that potassium appears to act as a facilitator in ensuring the brain’s ability to properly utilise serotonin.
Potassium counteracts the thoughts and feelings associated with depression and instead activates neurons involved in positive thoughts and feelings. Without the electrical charge sparked by potassium, neurotransmitters like serotonin cannot be utilised to make us feel better. This explains why even a slight decrease in potassium levels can result in significant feelings of anxiety.
8. Helps Prevent Osteoporosis
Potassium helps maintain bone density and may reduce the risk of osteoporosis, particularly in older adults. Potassium does this by cutting down on how much calcium leaves your body in your urine, keeping this calcium around helps to keep bones strong.
9. Helps Regulate Fluid Balance
The amount of water in your intracellular fluid (water found inside your cells) and extracellular fluid (water found outside your cells in areas such as your blood and spinal fluid) is directly affected by your electrolytes, potassium and sodium. Potassium is the main electrolyte in the intracellular fluid and determines the amount of water inside the cells. It’s therefore crucial that you consume the right electrolytes, including potassium.
How Much Potassium Do You Need?
Adults (19 to 64 years) need 3,500mg of potassium a day (UK NHS guidelines). You should be able to get all the potassium you need from your daily diet.
The recommended daily intake varies by age and gender:
- Adults: 3,500mg per day
- Pregnant women: 3,500mg per day
- Breastfeeding women: 3,500mg per day
Most people can get adequate potassium through diet alone, but certain conditions or medications may require monitoring.

Signs of Potassium Deficiency (Hypokalemia)
Not enough potassium can make your muscles weak. Common symptoms include:
- Muscle cramps and twitches
- Constipation
- Fatigue and weakness
- Irregular heartbeat
- Mood changes and irritability
- Mental fatigue
It is possible to have hypokalemia because you don’t get enough potassium from food, but it’s more likely to happen with conditions like Crohn’s disease or ulcerative colitis, if you have severe vomiting or diarrhoea, or if you’re taking certain medications.
If you have low potassium, foods are a great natural source. Your doctor may even recommend that you supplement with potassium. To find out how much potassium is in the fluid part of your blood, the NHS has a potassium test.
Can You Have Too Much Potassium? (Hyperkalemia)
A healthy individual will naturally pass extra potassium out of the body, so most people don’t actually have to worry about getting too much potassium. However, if something makes it hard for your body to get rid of potassium, it can cause hyperkalemia.
Those at risk include people with kidney conditions and those who take certain types of medicines. Bear in mind that hyperkalemia doesn’t always cause symptoms. It can, however, make your muscles feel weak or cause nausea.
Important: Always consult your GP before taking potassium supplements. Too much potassium can be dangerous, particularly for people with kidney problems.
Is It Safe To Take Potassium as a Supplement?
Yes. Potassium is generally safe to take as a supplement when used appropriately, but it’s crucial to consult your GP first, especially if you have kidney problems or take certain medications.
Is It Safe To Take Potassium Everyday?
Yes. According to the best available evidence, potassium has no negative side effects when supplemented appropriately. One 2019 report suggests that the highest daily dose of potassium you can safely consume is 3 grams per day. However, the European Food Safety Authority (EFSA) suggested in its 2012 guidelines that you can safely take up to 6 grams per day.
Current Dosage Recommendations
Based on recent research and clinical guidance:
For general health: 3,500mg per day from food sources (UK NHS guidelines)
For supplementation: Only under medical supervision
Best timing: With meals to enhance absorption and reduce stomach upset
Dietary sources: Leafy greens, beans, potatoes, fruits, fish, and dairy contain natural potassium
- Plant-based option: Supplements available for those who cannot meet needs through diet alone
Frequently Asked Questions
Q: Does potassium immediately calm anxiety?
Potassium doesn’t provide instant relief like anti-anxiety medication. However, maintaining adequate potassium levels through diet supports overall nervous system function and may reduce anxiety symptoms over time. The 2024 case study showed initial improvements within one week of supplementation.
Q: Can I take potassium supplements for anxiety?
Always consult your GP before taking potassium supplements. Too much potassium can be dangerous, particularly for people with kidney problems. Most people can meet their needs through a balanced diet rich in potassium-containing foods.
Q: What’s the link between potassium and stress hormones?
Potassium helps regulate the production and effects of stress hormones like cortisol and adrenaline. Adequate potassium levels support the body’s stress response system, helping to prevent excessive anxiety and tension.
Q: How long does it take for potassium to affect mood?
Individual responses vary, but research suggests noticeable improvements in mood and anxiety may occur within 1-4 weeks of maintaining adequate potassium levels through diet or supervised supplementation.
Q: Can low potassium cause panic attacks?
While low potassium alone may not directly cause panic attacks, it can contribute to symptoms like heart palpitations, muscle weakness, and fatigue that may trigger or worsen anxiety and panic symptoms.
Q: Which is better for anxiety: potassium or magnesium?
Both minerals play important roles in nervous system function. Potassium regulates nerve signals and stress hormones, whilst magnesium helps calm the nervous system. A balanced diet containing both minerals is ideal for overall mental health.
Q: Do bananas really help with anxiety?
Bananas contain potassium (451mg per medium banana), which supports nervous system function. However, many other foods contain more potassium per serving. Swiss chard, white beans, and baked potatoes all provide double the potassium of a banana.
Q: Can potassium help with sleep and anxiety?
Yes. Potassium supports the production and regulation of neurotransmitters involved in sleep and mood regulation, including serotonin. Adequate potassium levels may improve both sleep quality and anxiety symptoms.
Q: What time of day should I eat potassium-rich foods?
There’s no specific best time. Spread potassium-rich foods throughout the day as part of balanced meals. Some people find eating potassium-rich foods in the evening supports better sleep.
Q: Can I test my potassium levels at home?
Standard blood tests at your GP surgery can measure serum potassium levels. However, the 2024 research notes that standard serum potassium tests only reflect blood levels and may not detect tissue-specific deficiencies in the brain and nervous system.

In this article, Human Performance Hub deep dives into L-carnitine’s effect on testosterone levels. We’ll cover L-carnitine, how it affects testosterone and the benefits of increased testosterone levels. So, let’s get right into it.
Does L-carnitine actually boost testosterone levels? Yes. L-carnitine is a supplement that has been gaining traction in the fitness community for its potential to increase testosterone levels. This amino acid helps the body produce energy, which means it also plays an important role in metabolism and weight loss. Please bear in mind however that more research is required surrounding the connection between L-carnitine and testosterone. This is because most of the research carried out so far focuses on animals (rats in particular).
Keep reading to learn more about how L-carnitine affects testosterone levels and why men are increasingly using this supplement to boost their vitality and performance.
Quick Summary: L-carnitine is an amino acid that encourages testosterone production, improves testicular function, and makes existing testosterone more active. For men with low testosterone, research shows L-carnitine can provide significant benefits including improved sexual function, energy levels, and libido. Key takeaway: L-carnitine works as a natural testosterone booster by optimising energy production at the cellular level.

Does L-Carnitine Boost Testosterone Levels?
Yes, for low testosterone, research suggests that the amino acid L-carnitine encourages testosterone production, improves testicular function and makes existing testosterone more active. In fact, L-carnitine plays key roles in energy generation and improving blood flow, with major benefits for men’s health.
Unfortunately, an inevitable consequence of ageing is a rapid decline in our cellular energy level. Generally speaking, this often manifests as a sense of overall fatigue, depression and loss of libido. However, taking L-carnitine leads to better carnitine levels within tissues. L-carnitine is responsible for fuelling energy production at the cellular level, whilst enhancing testosterone formation.
Studies Supporting The Claims
Scientific research has started to explore the potential benefits of acetyl L-carnitine for increasing testosterone production. In fact, a study found that men with low testosterone levels who were supplemented with acetyl L-carnitine experienced a 15% increase in testosterone levels. On top of this, acetyl L-carnitine has been shown to improve sperm count and motility in men with fertility issues. It may also enhance exercise performance, which can indirectly lead to higher testosterone levels (1, 2).

How Does L-Carnitine Boost Testosterone Levels?
L-carnitine encourages optimal testosterone levels in a number of ways. Understanding these mechanisms can help you appreciate why this supplement has become so popular amongst men seeking to optimise their hormonal health.
Testosterone Production
It appears to directly stimulate production of testosterone. A recent study showed that serum levels of carnitine were independently associated with free testosterone concentrations in men. Consequently, lower levels of carnitine translated into lower testosterone.
Research indicates that L-carnitine can help restore luteinizing hormone (LH), which in men is a hormone that controls testosterone production. Testosterone is made in Leydig cells in the testes, and carnitine exerts a protective effect on the cells of the testes. The function of the testes depends on sexual hormones such as follicle-stimulating hormone (FSH), luteinizing hormone and testosterone (3, 4).
Studies have found that in subjects with depressed testicular function, supplementation with L-carnitine enhances the recovery of serum sex hormone levels including luteinizing hormone, with resulting benefits to testosterone production, sperm count, and sperm motility (5).
Androgen Receptors
L-carnitine improves the number of androgen receptors and their sensitivity to testosterone. Active receptors are necessary to receive and bind testosterone and for the hormone to carry out all of its normal functions. For testosterone to exert any effect on the body, it must first bind to an androgen receptor inside a cell. The attaching of testosterone to its receptors ‘switches on its actions’.
In fact, studies have shown that taking 2,000mg daily of an L-carnitine supplement can boost male androgen receptors within 3 weeks. This is particularly important because there might be plenty of testosterone in the blood but without active receptors, the hormone cannot bind to tissues and bring its benefits (6).
Energy Production and Nitric Oxide
Propionyl-L-carnitine is an amino acid that is naturally produced in the body. This particular amino acid is essential for the delivery of fatty acids to the mitochondria that fuel energy production in each cell. For male hormone output, propionyl-L-carnitine boosts production of nitric oxide, which directly parallels increasing testosterone levels. Nitric oxide and testosterone are inextricably linked: higher nitric oxide leads to better testosterone synthesis in a man’s testes (7).
Types of L-Carnitine for Testosterone
There are several types of carnitine available, each with slightly different properties and benefits. Understanding the differences can help you choose the right form for your goals.
Acetyl L-Carnitine (ALCAR)
Acetyl L-carnitine is known for its ability to boost testosterone levels and improve cognitive function. It crosses the blood-brain barrier more easily than standard L-carnitine, making it beneficial for both physical and mental performance. This form is particularly effective for men with low testosterone seeking to restore optimal levels.
Propionyl L-Carnitine (PLC)
Propionyl L-carnitine is specifically beneficial for boosting nitric oxide production, which directly supports testosterone synthesis. This form is particularly effective for improving erectile function and sexual performance. Studies show that PLC at 2,000mg per day can improve testosterone-related functions more effectively than standard L-carnitine.
L-Carnitine L-Tartrate (LCLT)
L-carnitine L-tartrate is a highly bioavailable form that’s particularly effective for athletes and those engaged in resistance training. Research shows that LCLT supplementation reduces exercise-induced muscle tissue damage and supports recovery. It also enhances the hormonal response to resistance exercise (8).
Standard L-Carnitine
Standard L-carnitine is the most common form and provides general benefits for energy production and metabolism. Whilst less targeted than other forms, it remains an effective option for supporting overall testosterone health.
Optimise your testosterone with the right form. Our L-Carnitine supplements are available in multiple forms to suit your specific health goals.
L-Carnitine vs Testosterone: Which Is Better?
According to the Italian study mentioned already, L-carnitine supplements can work as effectively as testosterone for male vitality and libido. Taking L-carnitine as propionyl-L carnitine at 2,000mg/day and L-carnitine 2,000mg/day, improved testosterone-related functions including erectile capacity, modestly exceeding the benefit seen with oral dosing of testosterone itself.
Researchers compared L-carnitine with testosterone in men who were experiencing erectile dysfunction, low libido, fatigue, and depression. They found that after six months of treatment, L-carnitine was more effective at boosting sexual performance and improving erections than actual testosterone, though the hormone helped somewhat. More importantly, testosterone had the unwanted side effect of causing an increase in prostate volume and size, while L-carnitine did not.
This makes L-carnitine an attractive natural alternative for men seeking to optimise testosterone levels without the potential side effects associated with hormone replacement therapy.
Key Advantages of L-Carnitine Over TRT:
- No increase in prostate volume or size
- More effective at improving erectile function
- Better for overall sexual performance
- Supports energy production at the cellular level
- Improves sperm count and motility
- No prescription required
- Fewer side effects reported
How To Use L-Carnitine for Testosterone Boosting
Acetyl L-carnitine is known for its ability to boost testosterone levels, however further research is needed to confirm its effectiveness in this area. Here are some of our top tips for taking L-carnitine to boost testosterone:
Dosage
Most studies showing testosterone benefits use 2,000mg per day, typically divided into two 1,000mg doses. Some studies have used dosages ranging from 1,000-3,000mg per day. Start with a conservative dosage of 1,000-1,500mg daily and assess your response before increasing.
We consume small amounts of L-carnitine in our diets by eating meat and fish, but our intake is not enough for a therapeutic effect on male testosterone production. L-carnitine is a water-soluble, vitamin-like molecule structurally. In the body, 75% of L-carnitine is ingested from supplements or the diet, and 25% is synthesized internally from two essential amino acids lysine and methionine. L-carnitine is then stored in skeletal muscles, heart, brain, and testes.
Timing
L-carnitine is best taken before exercise to maximise its effects on energy production and hormonal response. Taking it with meals containing carbohydrates and protein can enhance absorption. Most athletes take one dose in the morning and another in the afternoon or evening.
Duration
Most studies showing significant testosterone benefits use supplementation periods of 8-12 weeks. Consistent use is important for results, as testosterone improvements typically manifest after 6-8 weeks of daily supplementation.
Who Benefits Most?
Vegetarians and vegans in particular can benefit from L-carnitine supplements, as can older adults as carnitine levels in the body decline as men age. In men, the decline in testosterone usually begins in their late thirties and decreases at a relatively constant rate of 1 to 3% per year. L-carnitine supplementation can help counteract this natural decline.

Benefits of Optimal Testosterone Levels
Understanding the benefits of optimised testosterone levels can help motivate you to take action. When testosterone is at healthy levels, men experience significant improvements across multiple areas of health and performance.
Sexual Function and Libido
Testosterone is essential for sexual desire and erectile function. Studies show that L-carnitine supplementation significantly improves erectile capacity, sexual performance, and overall sexual satisfaction in men with low testosterone.
Energy and Vitality
Optimal testosterone levels support cellular energy production, reducing fatigue and depression. Men with healthy testosterone report feeling more energetic, motivated, and mentally sharp throughout the day.
Muscle Growth and Strength
Testosterone is crucial for building and maintaining lean muscle mass. Higher testosterone levels support muscle protein synthesis and recovery from resistance training, making it easier to build and maintain muscle.
Bone Density
Testosterone plays a vital role in maintaining bone density. Low testosterone increases the risk of osteoporosis and fractures, whilst optimal levels protect bone health.
Metabolic Health
Testosterone supports healthy metabolism and body composition. Men with optimal testosterone levels find it easier to maintain a healthy weight and reduce body fat.
Cardiovascular Health
Research shows that healthy testosterone levels support cardiovascular function and reduce the risk of heart disease.
Mood and Cognitive Function
Testosterone influences mood, confidence, and cognitive performance. Optimal levels support mental clarity, focus, and emotional well-being.
What Is Testosterone?
Generally speaking, as men age, their testosterone levels naturally decline, leading to a variety of health issues such as decreased libido and muscle mass. Testosterone is an essential hormone for male health, responsible for bone density, sexual function and muscle growth.
Testosterone is produced primarily in the testes through the action of luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones signal the Leydig cells in the testes to produce and release testosterone. A healthy testosterone level is essential for maintaining physical and mental health in men.
The normal testosterone range for adult men is approximately 300-1000 ng/dL, though this varies based on age, health status, and individual factors. As men age, testosterone naturally declines, which can contribute to fatigue, reduced libido, decreased muscle mass, and mood changes.
Whilst there are many ways to boost testosterone levels, acetyl L-carnitine has proven to be successful in boosting men’s testosterone levels. Despite this, it’s important to talk to a healthcare professional before starting any supplement regimen.

Does Taking Berberine Impact Exercise?
There’s limited evidence to suggest that berberine directly impacts exercise. It may, however, impact results. Research into the effects of berberine on metabolism, glucose intake and recovery suggests that it increases energy levels. It may also encourage both fat loss and energy storage in the muscles, making it an ideal supplement for bodybuilders.
Studies found that berberine downregulates genes that are responsible for cholesterol absorption into the intestines, preventing fat accumulations (1, 2). It also activates brown fat thermogenesis which can improve energy levels whilst limiting weight gain. Additionally, berberine may benefit recovery from exercise in that it possesses antioxidant and anti-inflammatory properties. Further to this, berberine may reduce oxidative stress markers, combatting the damage associated with intense workouts.

Does Berberine Affect Muscle Gain?
Berberine has a similar action to insulin, improving glucose uptake into cells. For those looking to build muscle, this boosts energy production, helps to prevent cell breakdown and increases energy storage, all of which are central to building muscle mass.
Berberine increases the uptake of glucose into cells, acting very similar to insulin. This is beneficial for muscle building, as it boosts energy production. Berberine can elevate energy storage levels and halt the breakdown of cells, both essential processes to building muscle mass.

Does Berberine Affect Testosterone?
Previously, research suggested that berberine could lower testosterone levels in men. However, more recent studies found that berberine does not lower testosterone in men. Although, trials found that berberine does lower testosterone in women that have polycystic ovary syndrome. Studies are inconsistent on this matter, with some researchers suggesting that the discrepancies between men and women may simply be down to dosage, or has some unknown relation to polycystic ovary syndrome.
More recent research has shown that berberine may increase testosterone levels in men, suggesting sex-specific effects. Bodybuilders take testosterone to increase their muscle mass and improve their athletic performance. By taking berberine, male testosterone levels increased and this promotes the growth of muscle mass.
Boost your muscle gain naturally. Our Berberine Complex is formulated to support energy production and muscle development.
Does Berberine Speed Up Metabolism?
Yes, berberine is shown to speed up metabolism. Berberine helps boost mitochondrial biogenesis in your muscle mass and help you to burn more energy, even while you are resting. This is because berberine activates brown fat thermogenesis and limits weight gain, rather than building white fat. Energy levels are increased as the body’s energy expenditure is improved.
Berberine is thought to speed up metabolism and reduce blood glucose. This limits the amount of glucose and lipids that get stored in the body, therefore assisting weight and fat loss.
Should You Take Berberine Before or After a Workout?
It doesn’t matter too much whether you take berberine pre-workout or post-workout, but note that it has a half-life of around 5 hours. The main thing to consider when taking berberine is that it shouldn’t be consumed on an empty stomach as it risks hypoglycemia.
As such, it’s best to take it with a meal. Most choose to take one serving with breakfast, and a second serving with their evening meal. This also accounts for the 5-hour half-life, allowing you to make the most of the supplement.
Fun fact: Berberine has been used in Indian Ayurvedic medicine for around 5,000 years.
How Much Berberine Should You Take?
How much berberine you take depends on your goals. But, if you’re looking to build muscle mass, most bodybuilders take around 1-1.5g of berberine per day, divided into 2-3 servings.
Always talk to a qualified practitioner if you need further specific advice for your health. Since berberine works best with meals, it is easy to incorporate into your daily routine by taking it with:
- Breakfast
- Pre-workout meal
- Post-workout meal
- Evening meal
Optimise your dosage with our experts. Our Berberine Complex comes with detailed guidance on how much to take for your specific goals.

Health Benefits of Taking Berberine
Aside from fat loss and metabolic benefits, berberine has a number of other health benefits, including:
Heart Health
Research suggests that berberine may be beneficial in a number of heart health concerns, including heart disease – the number one cause of death worldwide. According to a review of 16 studies, berberine may:
- Lower total cholesterol
- Lower LDL (bad) cholesterol
- Lower blood triglycerides
- Increase HDL (good) cholesterol
Further to this, diabetes, high blood sugar levels, and obesity are also major risk factors for heart disease, all of which seem to be improved with berberine. People with heart disease often have fatigue and irregular heartbeats. Studies show that taking a berberine supplement combined with standard heart disease treatments eases these symptoms, lowering the chance of death without apparent side effects.
Brain Health and Neuroprotection
Berberine has been found to possess many positive neuroprotective effects. Research has shown that berberine improves the survival, development and function of neurons. Berberine can help protect the brain from toxins and aid with memory retention. Studies have also found that berberine can act as an antioxidant and support the brain against oxidative stress. This prevents conditions such as cancer, diabetes and heart disease.
Research shows that berberine might help prevent dementia by protecting against brain damage and improving mental skills. Early studies also suggest that it may one day be able to treat conditions like cognitive dysfunction and Alzheimer’s disease. Berberine also may improve the symptoms of depression.
Gut Health and Microbiota
Berberine has been shown to protect the gut barrier from inflammation. It also kills harmful gut bacteria and encourages the growth of healthy bacteria, which may help treat conditions like diabetes and high cholesterol. Our own Human Performance Hub GI Microbial supplement helps to diversify the gut biome and maximise digestive health.
Anti-Inflammatory and Antioxidant Properties
Berberine lowers inflammation in many ways. For example, it reduces oxidative stress, lowers production of inflammatory proteins, and promotes immune regulation. Its anti-inflammatory activity may mean it can treat inflammatory conditions like arthritis. Berberine is shown to have potent antioxidant and anti-inflammatory properties, which help combat oxidative stress markers and the damage associated with intense workouts.
Other Health Benefits
- Reduces the growth of harmful microorganisms, including bacteria, viruses, and fungi
- May reduce fat build-up in the liver
- May help lower blood pressure
- May improve blood sugar control and insulin sensitivity
- May support weight loss and body composition
Important Considerations for Athletes
Whilst berberine offers many potential benefits, it’s important to understand that berberine is a supplement and supplements are not regulated by the FDA. Like any supplement, you really have no idea what you’re taking in without proper sourcing.
Some sports medicine experts note that appetite suppression and an increase in glucose uptake – two of berberine’s proposed benefits – may actually be detrimental to active individuals who rely on glucose for fuel. If berberine is suppressing your appetite and promoting hypoglycemia (low blood sugar), that could lead to dangerous hypoglycemia. Profound hypoglycemia can cause seizures, unconsciousness, and rapid heart rates.
For this reason, it’s essential to consult your doctor before you start taking berberine, particularly if you’re an active athlete or have any existing health conditions.

Frequently Asked Questions
Does berberine work like a pre-workout?
Berberine works differently than stimulant-based pre-workouts. It enhances metabolic efficiency and nutrient delivery rather than providing immediate energy. Many athletes use both complementary products.
How long does berberine take to work?
You may notice improved energy within 1-2 weeks. Metabolic and performance benefits typically appear after 4-6 weeks of consistent use.
Can I take berberine with other supplements?
Yes. Berberine works well alongside other performance supplements. However, always check with a healthcare provider if you’re taking multiple supplements or medications.
Is berberine safe for long-term use?
Research suggests berberine is safe for extended use at recommended dosages. However, consult your doctor if you’re on medications, especially those affecting blood sugar or blood pressure.
What’s the difference between berberine and metformin?
Early research suggests that metformin may help manage diabetes better than berberine. A study on mice found that whilst berberine was better at reducing high cholesterol and obesity, metformin was better at controlling blood sugar levels. Berberine may hinder certain liver enzymes involved in metabolising drugs, which could impact how the body breaks down medications.
Is berberine the same as Ozempic?
Although some call berberine “nature’s Ozempic,” the comparison may be exaggerated. The two also work in different ways. Whilst Ozempic slows down digestion, berberine helps control how the body breaks down and uses energy. Unlike Ozempic, berberine is a dietary supplement that has not gone through the FDA approval processes for weight loss.
Can women take berberine?
Yes, berberine is safe for most women. However, women with PCOS (polycystic ovary syndrome) should consult a healthcare provider first, as berberine may lower testosterone in this specific condition.
Should I stop berberine before surgery?
It’s generally recommended to stop taking herbal supplements like berberine 2-3 weeks before surgery to avoid negative reactions to anaesthesia and side effects like excessive bleeding. Berberine’s effects on blood clotting and blood sugar levels may impact the success of surgery and recovery time.

Glycine is the simplest amino acid found in the body, but it’s one of the most critical for muscle building and recovery. Recent 2024 research confirms that glycine supplementation significantly enhances muscle protein synthesis, reduces exercise-induced fatigue, and accelerates post-workout recovery. Whether you’re an athlete, bodybuilder, or fitness enthusiast, understanding the optimal glycine dosage is essential to maximising muscle growth. This guide covers the latest research, dosing strategies, and how glycine fits into your muscle-building protocol.
You should be taking 12 grams of glycine to build muscle. This is because your body naturally produces around 2.5 grams daily, which falls short of the optimal amount needed for metabolic function and muscle growth. As glycine is a vital component of the compounds creatine and collagen, you need the optimal amount of glycine to build muscle.
Read on to learn more about taking glycine to build muscle and the amounts you should be taking.
How Much Glycine Is Needed To Build Muscle?
The optimal amount of glycine is 15 grams per day for your metabolism to function effectively. As the body only produces around 2.5 grams of glycine daily, supplements can help you reach the optimal amount to build muscle more effectively.
Here at Human Performance Hub, we have glycine powder, the ideal solution for you. We recommend consuming 30 grams (1 scoop of our glycine powder product) with water or any other beverage per day or as your health care practitioner guides.

Latest Glycine Research (2024-2025)
Recent scientific reviews published in 2024 have provided significant insights into glycine’s role in athletic performance and muscle development. Here’s what the latest research shows:
Key 2024 Findings
A comprehensive review published in Sports (2024) examined glycine’s potential as an ergogenic aid and found:
- Glycine supplementation may enhance peak power output during high-intensity exercise
- Reduces lactic acid accumulation during intense training sessions
- Improves sleep quality and recovery between workouts
- Activates mTORC1 signaling, a critical pathway for muscle protein synthesis and hypertrophy
- Decreases pro-inflammatory cytokines (TNF-alpha and IL-6), which accelerates recovery post-exercise
The mTORC1 Connection
Recent research highlights that glycine combined with resistance training upregulates mTORC1 (mammalian target of rapamycin) signaling. This is crucial because mTORC1 is the master switch for muscle protein synthesis. Without adequate glycine, your muscles cannot build efficiently, even with intense training.
Collagen Synthesis for Muscle Repair
High glycine concentrations increase type 2 collagen synthesis by 2.5 times in muscle tissue. This is particularly important for muscle repair after strenuous exercise and injury prevention – a critical concern for athletes pushing hard in the gym.
Is Glycine Good For Building Muscle?
Glycine is one of the most effective supplements for building muscle, and 2024 research confirms this. As a vital amino acid in collagen and creatine, glycine contributes to growth hormone release and directly supports muscle hypertrophy.
Muscle Protein Synthesis
Glycine is essential for muscle protein synthesis, growth, and repair. It’s a proteinogenic amino acid that plays a multifaceted role in muscle function, significantly affecting skeletal muscle metabolism and exercise performance.
Creatine Production
Glycine and arginine work together to increase creatine synthesis in skeletal muscle. Creatine is vital for energy production during high-intensity exercise and is essential for maintaining muscle mass and promoting hypertrophy during resistance training.
Growth Hormone Release
Studies have shown that high dosages of glycine intake can cause an increase in growth hormone release, which directly results in muscle-building.
Joint and Tendon Protection
Glycine is a crucial component in collagen, making it directly responsible for protecting and strengthening joints and tendons. This is critical for those building muscles as it protects your tissue from damage when working out. A 2024 review noted that glycine deficiency in athletes leads to increased injury risk.
Anti-Inflammatory Benefits
Recent research shows glycine decreases the production of pro-inflammatory cytokines such as TNF-alpha and IL-6, and inhibits the NF-κB pathway. This means faster recovery post-exercise and reduced muscle soreness.
How Do I Take Glycine?
Glycine is widely available in capsule or powder form. If you don’t enjoy taking tablets, the powder form easily dissolves into water and tastes sweet. Due to its sweet taste, it can easily be incorporated into your nutrition in foods such as:
- Water
- Coffee/Tea
- Soups
- Oatmeal
- Yoghurt
- Pudding
- Protein Shakes/Smoothies
- Bone Broth Drinks
Glycine Dosing for Different Athletic Goals
While 15 grams per day is the standard recommendation, recent research suggests dosing can be optimised based on your specific goals:
For Muscle Building and Strength
- Standard dose: 15 grams per day
- Optimal timing: 5-10g with post-workout meal to maximise muscle protein synthesis
- Duration: Consistent daily intake for at least 8-12 weeks to see significant muscle growth
For Older Adults and Recovery
- A 2024 clinical trial found that 1.33 mmol/kg/day of glycine combined with resistance training for 24 weeks significantly increased strength and exercise capacity
- Decreased inflammation and body fat
- Lowered waist circumference
- Improved overall muscle function in adults aged 71-80 years
Important Safety Note on Dosing
Recent research emphasises that high doses exceeding 500 mg/kg of body mass could potentially induce cytotoxic effects and contribute to glutamate toxicity. Stick to the recommended 15 grams per day to avoid any adverse effects.
Other Benefits of Glycine
Some other benefits of taking glycine supplements are:
1. Improves Sleep
As glycine is an amino acid, it can have a calming effect on the brain and may help people fall asleep easier. Research has also shown that glycine can help people stay asleep for longer due to the lower temperature of the body.
Read more about the sleep-related benefits of Glycine in our in-depth blog ‘Does Glycine Make You Sleepy?’.
2. Boosts Metabolism
Glycine regulates the metabolism of cells. Research has shown that glycine can treat conditions such as diabetes. Glycine has been shown to decrease visceral fat stores by 50%, which helps you lose weight, which is beneficial when building muscle.
3. Improves Heart Health
As glycine is a powerful antioxidant, some research has shown that this amino acid can reduce the risk of heart disease. Glycine prevents the accumulation of a compound that, in high amounts, has been linked to atherosclerosis (the hardening and narrowing of the arteries).
4. Brain Food
Glycine contributes to making the compound of creatine. Creatine has been linked to healthy brain function and memory. Creatine has also been shown to increase muscle size, strength and power. This is ideal for those trying to build muscle, as glycine is a crucial component and getting too little may reduce how much creatine you are producing.
Fun Fact: Scientists have shown interest in using glycine to treat schizophrenia and improve memory due to its involvement in transmitting chemical signals in the brain.
5. Lowers Inflammation
Another benefit of glycine is that it lowers inflammation in your cells. This is ideal for those building muscle, as glycine can help to heal any muscle damage and prevent cell damage.
To learn more about the benefits of taking glycine, check out our dedicated blog, ‘The Top 7 Benefits Of Glycine Powder’.
Glycine and Exercise Performance
Beyond muscle building, recent 2024 research highlights glycine’s role in athletic performance:
Reduces Lactic Acid Accumulation
Glycine supplementation may reduce lactic acid accumulation during high-intensity exercise, potentially allowing you to train harder for longer before fatigue sets in. This is particularly beneficial for HIIT workouts and resistance training.
Enhances Recovery Between Sets
By reducing inflammation and supporting the one-carbon cycle (important for cellular energy production), glycine helps your muscles recover faster between sets and training sessions.
Improves Sleep Quality
Glycine’s calming effect on the brain and its ability to lower body temperature make it particularly effective for improving sleep quality – which is when most muscle growth actually occurs. Better sleep means better recovery and faster muscle gains.

Your 7-Day New Year Reset: The Science-Backed Supplement Stack That Actually Works
Between Christmas and New Year, most people make resolutions they abandon by January 15th. Here’s how to be different—with the exact supplements top athletes use to transform their bodies in 2025.
You’ve just finished Christmas. Your body feels sluggish. Your energy is low. Your digestion is off. And you’re thinking about New Year resolutions that—let’s be honest—you’ll probably abandon by mid-January.
But what if there was a science-backed way to reset your body in just 7 days, using supplements that actually work? Not gimmicks. Not fad products. Real compounds backed by research that elite athletes and high performers use year-round.
This article reveals the exact supplement stack that transforms your body between Christmas and New Year—so you start 2025 with energy, clarity, and momentum that lasts.
Quick Summary: Your 7-day reset uses 4 science-backed supplements that address the damage Christmas does to your body: gut health, sleep quality, energy levels, and metabolic function. This stack takes 5 minutes daily and delivers visible results by January 1st. Most importantly, it builds momentum for sustainable 2025 goals.

Why a 7-Day Reset Actually Works (The Science)
Christmas does real damage to your body. Not moral damage—biological damage.
Between December 20th and 26th, the average person consumes:
- 7,000+ extra calories (equivalent to 2+ weeks of normal eating)
- 3x normal sugar intake
- Disrupted sleep patterns (late nights, alcohol, sugar crashes)
- Zero exercise for most people
- Compromised gut bacteria from processed foods
This creates a cascade of problems:
The Post-Christmas Damage Cascade
Day 1-2 (Boxing Day): Insulin resistance spikes. Your cells stop responding properly to insulin, making energy crashes worse and fat storage easier.
Day 3-5: Gut dysbiosis develops. Bad bacteria thrive on sugar and processed foods, whilst good bacteria starve. This triggers inflammation, bloating, and brain fog.
Day 6-7: Sleep quality collapses. Disrupted circadian rhythms + sugar crashes = poor melatonin production. You feel exhausted but wired.
Day 8+: Metabolic adaptation. Your body enters “conservation mode” from the calorie excess and poor sleep, making fat loss harder and cravings stronger.
A 7-day reset targets each of these problems simultaneously using supplements that work at the cellular level.
Why 7 Days? The Science
Research shows that:
- Gut bacteria respond in 3-5 days to dietary changes and targeted supplementation (Wang et al., 2025)
- Sleep quality improves within 5-7 days of consistent supplementation with taurine and glycine (PMC Sleep Studies, 2024)
- Insulin sensitivity recovers in 7-10 days with proper nutrition and targeted compounds like berberine (Journal of Clinical Nutrition, 2024)
- Energy levels stabilise in 5-7 days once gut health and sleep improve
Seven days isn’t arbitrary—it’s the minimum time needed for your body’s systems to reset and stabilise.
Ready to start your reset? Scroll to the shopping list below to grab everything you need. Most customers complete their 7-day reset for under £156.
The 4-Supplement Stack Explained
This stack targets the 4 systems that Christmas damages most: gut health, sleep, energy, and metabolism. Each supplement has a specific job.
Supplement #1: Bone Broth Protein (Gut Health + Protein)
Why it matters: Christmas destroys your gut. Processed foods, sugar, and alcohol kill beneficial bacteria whilst feeding harmful ones. Your gut barrier becomes “leaky,” triggering inflammation and brain fog.
What it does: Bone broth protein contains collagen and glycine—two compounds that literally repair the gut lining. Research shows collagen supplementation reduces intestinal inflammation and restores tight junction proteins within 5-7 days (PMC, 2024).
Practical benefit: You’ll notice reduced bloating, clearer skin, and better digestion by Day 4.
Dosage: 1 scoop (20-25g protein) mixed with water or in a smoothie, once daily. Best taken in the morning or post-workout.
Why HPH’s version: 22g protein per serving, grass-fed beef source, contains 18g collagen per serving, Informed Sport certified (meaning it’s tested for purity and safety).
Supplement #2: Taurine (Sleep Quality + Recovery)
Why it matters: Christmas disrupts your sleep-wake cycle. Late nights, alcohol, and sugar crashes destroy melatonin production. Poor sleep = higher cortisol = stronger cravings + slower metabolism.
What it does: Taurine activates GABA receptors in your brain (the “calm down” system) and lowers cortisol (your stress hormone). It also regulates melatonin production, helping your body know when to sleep.
Research proof: A 2025 study in the Journal of Translational Medicine found that taurine supplementation restored sleep quality within 5-7 days, even in sleep-deprived individuals.
Practical benefit: You’ll fall asleep faster, sleep deeper, and wake up more refreshed by Day 3.
Dosage: 500-1000mg taken 1-2 hours before bed.
Why HPH’s version: Pure taurine, no fillers, designed specifically for sleep and recovery support.
Supplement #3: Berberine (Metabolism + Energy)
Why it matters: Christmas causes insulin resistance. Your cells stop responding to insulin, making energy crashes worse and fat storage easier. Berberine fixes this at the cellular level.
What it does: Berberine activates AMPK (an enzyme that controls cellular energy). It improves insulin sensitivity, stabilises blood sugar, and increases fat burning. Research shows a 3-5% increase in metabolic rate within 7-10 days.
Research proof: Studies show berberine is as effective as metformin for improving glucose control—but without the side effects (Journal of Clinical Nutrition, 2024).
Practical benefit: Energy crashes disappear. You’ll feel stable, focused, and less hungry by Day 5.
Dosage: 500mg taken with meals, 2-3 times daily (total 1000-1500mg per day).
Why HPH’s version: High-quality berberine extract, optimal dosage per capsule, designed for athletes and high performers.
Supplement #4: Magnesium + Vitamin D3 (Hormonal Balance + Immunity)
Why it matters: Christmas depletes two critical nutrients: magnesium (used for stress response, sleep, muscle function) and vitamin D (immune function, mood, bone health). This combination creates a perfect storm of fatigue and illness.
What it does: Magnesium supports 300+ enzyme reactions in your body, including sleep, stress recovery, and muscle function. Vitamin D3 regulates immune function and mood. Together, they restore hormonal balance.
Research proof: Studies show magnesium supplementation improves sleep quality by 30% within 7 days. Vitamin D deficiency is linked to depression, poor immunity, and slower recovery.
Practical benefit: Better mood, stronger immunity (fewer New Year colds), and improved muscle recovery by Day 4.
Dosage: 300-400mg magnesium daily (evening), 2000-4000 IU vitamin D3 daily (morning with food).
Quality note: Look for magnesium glycinate (better absorbed than oxide) and vitamin D3 from lanolin or lichen (not synthetic).
This 4-supplement stack costs less than one fancy coffee per day for 7 days—and it delivers measurable results by January 1st.
Your Day-by-Day Reset Plan
The goal: Simple, consistent supplementation that requires 5 minutes daily.
Morning Routine (2 minutes)
- Vitamin D3 (2000-4000 IU) with breakfast
- Berberine 500mg with a meal
- Drink 500ml water with a pinch of salt (restores electrolytes)
Midday (1 minute)
- Berberine 500mg with lunch
- Bone Broth Protein shake (20-25g protein, water or almond milk)
Evening Routine (2 minutes)
- Berberine 500mg with dinner
- Magnesium 300-400mg (glycinate form) with water, 1-2 hours before bed
- Taurine 500-1000mg with water, 1-2 hours before bed
Daily Nutrition Guidelines (Supports the Stack)
The supplements work best with proper nutrition. You don’t need to be strict—just follow these principles:
- Protein at every meal: Aim for 25-30g per meal (bone broth shake counts)
- Whole foods only: No processed foods, no sugar, no alcohol for 7 days
- Vegetables with every meal: Especially leafy greens (support magnesium absorption)
- Healthy fats: Olive oil, avocado, nuts, fatty fish (support hormone production)
- Hydration: 2-3 litres of water daily (supports detoxification)
- Sleep: Aim for 8 hours (the supplements help, but sleep hygiene matters)
Day-by-Day Expectations
Days 1-2: You might feel slightly worse before better. This is normal—your body is clearing out sugar and processed foods. Stay consistent.
Days 3-4: Sleep improves noticeably. Bloating starts to reduce. Energy becomes more stable.
Days 5-6: Brain fog clears. Cravings disappear. You’ll notice your clothes fit slightly better.
Day 7: Full reset. You feel energised, clear-headed, and ready to start 2025 with momentum.
What to Expect: Real Results Timeline
By Day 3
- Sleep quality improves (deeper, more restorative)
- Morning grogginess reduces
- Energy crashes become less severe
By Day 5
- Bloating noticeably reduces
- Brain fog clears
- Cravings for sugar and processed foods disappear
- Digestion improves
- Skin looks clearer
By Day 7
- Energy levels stabilise (no more crashes)
- Mental clarity improves
- Mood lifts (cortisol is lower)
- Clothes fit slightly better
- You feel ready to start 2025 with momentum
Important: What This Reset Is NOT
This isn’t a weight loss program. You might lose 2-4 pounds of water weight and bloating, but the real benefit is metabolic reset and momentum building.
The true value appears in Week 2 onwards, when:
- Your body naturally craves healthier foods
- Exercise feels easier (better energy, faster recovery)
- Sleep quality remains high
- You maintain the habits you’ve built
Most people who do this 7-day reset continue the stack into January and beyond—because they feel the difference.
The reset works because it’s simple and science-backed. No extreme diets. No 2-hour workouts. Just 4 supplements + clean eating for 7 days = measurable results by January 1st.

Frequently Asked Questions
Can I do this reset if I have dietary restrictions?
Vegetarian: Yes. Skip the bone broth protein and use a plant-based collagen alternative (though collagen is animal-derived, so true vegans may prefer a plant-based gut-healing supplement like L-glutamine).
Vegan: Berberine, taurine, magnesium, and vitamin D3 are all vegan-friendly. For protein, use a high-quality plant-based protein powder.
Allergies: All HPH supplements are free from common allergens. Check labels for your specific allergies.
What if I’m already on medications?
Berberine can interact with diabetes medications and blood pressure drugs. Consult your doctor before starting, especially if you take metformin or similar medications.
Can I do this reset multiple times per year?
Yes. Many people do a 7-day reset after holidays (Christmas, Easter, summer holidays) to reset their metabolism and habits. It’s safe to repeat every 3-4 months.
What if I miss a day?
Don’t stress. Just pick up where you left off. The reset is about consistency, not perfection. Missing one dose won’t derail your progress.
Will I feel withdrawal symptoms?
Possibly, especially if you’re used to high sugar intake. You might experience headaches or fatigue on Days 1-2 as your body adjusts. This is normal and temporary. Stay hydrated and get extra sleep.
Can I exercise during the reset?
Light exercise (walking, yoga, stretching) is fine. Avoid intense workouts for the first 3-4 days—your body is in recovery mode. Resume normal training by Day 5.
How long do the benefits last?
The 7-day reset resets your baseline. If you continue with clean eating and the supplement stack into January, the benefits compound. Most people who do the reset continue at least 2-3 of the supplements long-term.
What’s the best time to start?
December 27th-30th is ideal. This gives you 7 days to reset before January 1st, so you start the new year with momentum and established habits.
Can I combine this with other supplements?
Yes, but keep it simple. The 4-supplement stack is designed to work together. Adding too many other supplements can complicate things. If you want to add something, consult our team.
What if I don’t see results by Day 7?
Results vary by individual. Some people see dramatic changes by Day 3; others take the full 7 days. Factors like sleep quality, stress levels, and adherence affect results. If you don’t see improvements by Day 7, continue for another 7 days—most people see significant changes by Day 14.
Your 2025 Starts Now—Not January 1st
The difference between people who succeed with New Year resolutions and those who fail is momentum. This 7-day reset builds that momentum.
You’ll start January 1st with:
- Stable energy (no crashes)
- Better sleep (deeper, more restorative)
- Clearer mind (no brain fog)
- Healthier gut (less bloating)
- Established habits (easier to maintain)
That’s not just a reset. That’s a foundation for 2025 success.

Taurine (2-aminoethanesulfonic acid) is an organic compound widely found in the human body. It is considered a conditional amino acid because it can be manufactured by the body. Taurine is essential for cardiovascular function, development of skeletal muscle, retinal function and the nervous system. One area that people tend to neglect are the benefits that taurine has on sleep. In this article, Human Performance Hub explores whether you should take taurine before bed and how it can impact sleep quality.
So, should I take taurine before bed? Whilst it is completely up to personal preference, taurine can be taken before bed to help you fall asleep more easily. This is because taurine helps lower cortisol levels, the stress hormones in the body. It also helps regulate the body’s production of melatonin, the chemical that signals to your brain when it should be feeling sleepy.
Keep reading to learn more about taurine’s impact on sleep and where to find any important information about this organic compound.
Key Takeaway: Taurine reduces cortisol levels and activates GABA receptors in your brain — two mechanisms that directly improve sleep quality and help you fall asleep faster.
Can I Take Taurine Before Bed?
Yes. Early research shows that taurine, especially if combined with other ingredients, can act as a natural sedative to calm anxiety and lessen reactivity to stress, therefore allowing you to sleep more easily at bedtime. Taurine is a naturally-occurring compound found in the body that increases in response to prolonged periods of being awake. It activates GABA (A) receptors in the brain region known to regulate sleep and is also involved in the creation of the ‘sleep hormone’ melatonin, in the pineal gland.
This is the taurine I use with clients — 1000mg, dosed for exactly this.
Does Taurine Help You Sleep and How Does Taurine Help You Sleep?
Taurine works through multiple mechanisms to improve sleep quality:
- 1.Reduces cortisol (your stress hormone)
- 2.Activates GABA receptors (calms your nervous system)
- 3.Regulates melatonin production (controls sleep timing)
- 4.Improves sleep quality (deeper, more restorative rest)
Martin Seeley, the CEO and sleep expert at Mattress Next Day, reported to The Mirror that taurine helps regulate a person’s sleep-wake cycle because it helps lower cortisol levels, otherwise known as the stress hormone, in the body. This means that taurine can promote restorative sleep more quickly because it stops you from feeling stressed before bed. He states that:
What Sleep Experts Say
“Taurine is a powerful amino acid that can help regulate your sleep-wake cycle and reduce the time it takes to fall asleep.” — Martin Seeley, Sleep Expert
“Whilst there’s still a lot of research that needs to be conducted to better understand taurine’s positive impact on sleep, it’s believed that taurine helps lower a person’s cortisol levels. As many studies show that stress can have a significant impact on how long it takes a person to fall asleep, taurine can, therefore, promote restorative sleep more quickly.“
Martin also added that taurine helps regulate the body’s production and release of melatonin, the chemical that signals to your brain when it should be feeling sleepy and when it should feel more awake.
Recent Research (2023-2025)
Sleep Deprivation & Gut Health Connection (2025)
Recent groundbreaking research published in the Journal of Translational Medicine (Wang, Zhou, Zheng) reveals a critical link between sleep deprivation, gut health, and taurine levels. The study found that sleep-deprived individuals exhibit significantly reduced taurine levels in their microbiome. Taurine, a sulfur-containing amino acid produced by gut bacteria, plays a crucial role in maintaining intestinal integrity and preventing metabolic disturbances linked to poor sleep. This research highlights that maintaining adequate taurine levels is essential for protecting gut health from the negative effects of sleep deprivation.
Sleep Deprivation & Skin Health (2025)
A 2025 study in PMC demonstrated that taurine supplementation can restore skin barrier function and collagen production in sleep-deprived individuals. The research showed that taurine works at the cellular level to promote tight junction proteins and enhance collagen production, effectively counteracting the skin damage caused by circadian rhythm disruption from poor sleep.
Taurine’s GABA Mechanism for Sleep (2023)
A 2023 comprehensive review in PMC confirmed taurine’s neuroprotective effects and its role as a GABA receptor agonist. This mechanism is key to sleep improvement – taurine activates GABA receptors in the brain, which reduces neuronal excitability and promotes relaxation. This scientific confirmation strengthens the article’s existing explanation about how taurine works.
Sources of Taurine
Taurine is a naturally-occurring substance mainly found in:
- Fish (Scallops, tuna, octopus)
- Meat (Beef, chicken, turkey)
- Dairy products
In addition to getting taurine from food, you can also get it from some energy drinks and supplements.
Myths and Misconceptions Surrounding Taurine
More often than not, people have never heard of the organic compound taurine; however, if you have heard of it, there is a good chance you will have come across some bizarre theories. Let’s dismantle some of these common misconceptions:
Let’s start with the word taurine. Whilst its name is derived from the zodiac name for bull, ‘Taurus’, it’s important to remember that taurine does not come from any part of the bull, in particular, bull’s urine or semen.
Fun fact – Historically, taurine was first isolated in 1827 from ox bile, which may help to explain its name and the enduring “made from bulls” myths
While many are aware of taurine’s ability to stimulate muscle growth and improve athletic performance, taurine actually promotes many more health benefits that are often neglected. Taurine has a number of other advantages, including its ability to provide relaxing sedative effects that help you fall asleep naturally.
Further Health Benefits of Taurine
Clinical studies have shown that supplemental taurine has many verifiable benefits, these include:
- Improves athletic performance, increasing endurance and strength
- May reduce the risk of cardiovascular disease by reducing blood pressure and inflammation
- May help to increase the growth of brain cells (can decrease the side effects of Parkinson’s disease)
- May help to treat metabolic syndrome. Researchers have found that taurine reduces triglycerides to prevent obesity, improves insulin resistance to regulate the metabolism of glucose, lowers cholesterol and reduces blood pressure.
- Taurine is an antioxidant, which means it can help prevent inflammation. Studies have shown it can actually help to heal periodontal disease.
- It can help prevent congestive heart failure and liver disease (hepatitis)
- In diabetics, taurine can improve blood sugar control.
Is It Safe To Take Taurine as a Supplement?
Yes. Taurine is completely safe to take as a supplement and has many benefits. Research studies have not identified any common side effects to date, however, bear in mind that there is not sufficient evidence to support the idea that taurine is the ‘best supplement for promoting sleep’.
Industry experts use their customers to vouch for taurine’s effectiveness as a sleep aid. According to them, 98% would recommend taurine to a friend, 97% reported that they slept better, 77% report that they were able to fall asleep faster and 78% reported that after trailing taurine, they woke up less frequently throughout the night.
Is It Safe To Take Taurine Everyday?
Yes. According to the best available evidence, taurine has no negative side effects when supplemented appropriately.
One 2019 report suggests that the highest daily dose of taurine you can safely consume is 3 grams per day. However, the European Food Safety Authority (EFSA) suggested in its 2012 guidelines that you can safely take up to 6 grams per day
If better sleep is the goal, this is where I’d start — one capsule 30–45 minutes before bed.
Current Dosage Recommendations
Based on recent research and clinical guidance:
For sleep support: 500-2000 mg per day (no associated side effects)
Optimal dosing: 1000 mg once or twice daily
Best timing: Evening, 1-2 hours before bed

Frequently Asked Questions About Taurine and Sleep
Q: How long does it take for taurine to work for sleep?
Most users report improvements within 3-7 days of consistent supplementation, though some notice effects within the first dose. Results vary based on individual metabolism and dosage.
Q: Can I take taurine with other sleep supplements?
Yes. Taurine works well with GABA, magnesium, and glycine for enhanced sleep support. However, avoid combining with stimulants like caffeine.
Q: Is taurine better than melatonin for sleep?
Both work differently. Taurine addresses cortisol and GABA receptors (the “why you’re stressed” problem), while melatonin signals sleep timing. Many users find combining both more effective than either alone.
Q: What’s the best time to take taurine for sleep?
Take 500-1000 mg approximately 1-2 hours before bed for optimal results.
Q: Will taurine make me drowsy during the day?
No. Taurine works by supporting your natural sleep-wake cycle, not by forcing drowsiness. It only promotes sleep when taken in the evening.
Q: Can vegetarians get taurine naturally?
Limited amounts from dairy products. Most vegetarians benefit from supplementation since taurine is primarily found in animal sources.
Q: Is taurine safe for long-term use?
Yes. Research shows no negative side effects with daily supplementation up to 6 grams per day (EFSA guidelines).
Taurine Supplements At Human Performance Hub
Now that you are aware of the many benefits of taking taurine, why not take a look at our taurine supplements at the Human Performance Hub.
If you are looking to improve the quality of your sleep, taurine supplements are a great way to help with recovery and sleep by downregulating the nervous system.
