What it is

L-glutamine is a non-essential amino acid, meaning the body can make it. It is found naturally in proteins and is abundant in muscle tissue. It can be produced commercially through fermentation using microorganisms.

Why it's used

It is often added to foods as a dietary supplement, particularly in sports nutrition products like protein powders and energy drinks. Manufacturers may add it to support muscle recovery and overall health.

Health notes

L-glutamine is generally recognized as safe (GRAS) by the FDA for use as a dietary ingredient. It plays a role in various bodily functions, including gut health and immune response. JECFA and EFSA have evaluated amino acids, but specific evaluations for L-glutamine's use as a food additive are not widely publicized. Research into its specific health benefits and optimal intake levels is ongoing.

Allergen info

L-glutamine is not derived from any of the nine major allergens recognized by the FDA. It does not contain gluten.
