Protects Muscle Tissue & Supports Immune FunctionGLUTAMINE is the most abundant amino acid in the human 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 is a major source of fuel for enterocytes (intestinal cells) and supports the integrity of the intestinal living as well as nucleotide synthesis by lymphocytes.*Jarrow formulas L-Glutamine is produced in Japanby microbiological fermentation and is USP/FCC grade.
