Glutamine is an amino acid essential for many important functions and for the optimal functioning of a number of tissues in the body, particularly the immune system and the gut:

- It prevents acidosis, helping the kidneys acid excretion
- Anabolic effect, and ergogenic effect
- It is the nutrient of gut cells
Athletes suffering from the overtraining syndrome (OTS) appear to maintain low plasma glutamine levels.

 All these observations have important implications for organ functions in these athletes, particularly with regard to the gut and the cells of the immune system, which may be adversely affected. In conclusion, plasma glutamine level may be useful as an indicator of an overtrained state.

Athletes should take 1,5 to 4,5 grams of L-Glutamine a day—supplementing it 2 to 3 times daily, between meals, above all when training intensity increase.
