L-Glutamine is the most abundant amino acid in muscle tissue; with intense training, glutamine levels can become severely depleted.

Why supplement with L-Glutamine?

  1. It is the primary fuel source for the intestinal mucosa; this makes it a fantastic supplement for repairing the intestinal lining. Heavy workout sessions can deplete glutamine levels, so topping up levels in a post-workout shake can prevent this. Here at Human Performance Hub, we take gut health very seriously, and glutamine is a go-to supplement when running a ‘gut repair’ protocol.
  2. Taking L-Glutamine post-workout has been shown to help with protein synthesis (muscle building). It does this by helping muscle cells stay hydrated and triggering a boost in growth hormone.
  3. L-Glutamine has also been shown to boost the immune system. After intense training sessions, the body is placed under a great deal of stress, so naturally, the immune system is suppressed, opening up a window for infection and illness. However, supplementing with glutamine provides the body’s immune system with an immediate fuel source, thus keeping it functioning optimally.

To summarise:

Glutamine taken post-workout will help build muscle tissue, increase immune function and also help to protect the gut lining.

One other less-known use for glutamine is that it significantly combat sugar cravings. When you experience a craving for carbohydrates, your brain usually wants sugar or glucose. Glutamine works as a healthy alternative to sugar as it fuels similar brain receptors, so if you find yourself reaching for a late-night cookie when you know you shouldn’t, then try 5 grams of L-glutamine instead, and the craving will soon pass!
