Glutamine is the most abundant amino acid in the body and is involved in many metabolic processes. Skeletal muscles are the primary sites of glutamine concentration. Glutamine protects muscle tissue and supports immune function during periods of immune and muscular stress. Glutamine supplementation supports protein synthesis as well as the rate of glycogen production (by serving as a carbon donor). Glutamine supports integrity of intestinal mucosal cells and nucleotide synthesis by lymphocytes.
