Glutamine provides a critical link in muscle metabolism not shared by any other single amino acid, and GL3 makes utilizing glutamine a realistic and effective endeavor. GL3 is pure, L-Glutamine in an odorless and tasteless powder.
Glutamine is the most abundant single amino acid in the blood and in the intracellular free amino acid pool (most abundant amino acid in muscle tissue). It comprises 61% of the amino acid pool in skeletal muscle. Glutamines unique structure, containing two nitrogen side chains, consists of 19% nitrogen - making it the primary transporter of nitrogen into the muscle cell. In fact, glutamine alone is responsible for 35% of the nitrogen that gets into the muscle cell. Glutamine literally drives muscle building nitrogen into the muscle cell where it is synthesized for growth.
Glutamine concentrations fall markedly after training and remain low until complete recovery. What this means is, the very rigors of weight training leak nitrogen carrying glutamine from muscle tissue. This fall in glutamine is catabolic to muscle tissue - The Training Paradox . Supplementing with glutamine spares free glutamine in muscle tissue, counteracts the fall in muscle protein synthesis, and improves nitrogen balance. Glutamine overcomes The Training Paradox .
