L-Glutamine is the single most abundant amino acid found in large amounts in the muscles. Because this amino acid helps to build and maintain muscle, it is useful for dieters, high intensity training atheletes and bodybuilders.

Glutamine is important in supporting a healthy digestive tract and is essential for supporting repair of the gastrointestinal tract.  The cells of the body require an adequate supply of glutamine as this is also a primary source of fuel for a healthy immune system and amino acid balance.
