Glutamine is one of the most versatile of all amino acids, and among the top aminos used by elite athletes. In short, glutamine levels are depleted during exercise, by supplementing with it you are replinshing the levels lost during hard training.*
Glutamine accounts for about 60% of the body´s total intramuscular free amino-acid pool and 20% of the total circulating amino acids. Unlike almost all other aminos, glutamine contains two nitrogen atoms. Because of this additional nitrogen atom, glutamine is called a nitrogen shuttle.* Glutamine is available in both powder and capsule forms.
