L-Glutamine is an amino acid found in the human body.  It is the most important amino acid because it plays an important role in strengthening the immune system, transporting nitrogen, and supporting protein synthesis.

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). The substance plays an important role in the cellular metabolism of animals and is the only amino acid with the ability to easily cross the barrier between blood and brain tissue. Combined, glutamine and glutamic acid are responsible for the vast majority of the amino nitrogen located in the brain, and are of central importance in the regulation of bodily ammonia levels. Glutamine is popularly sold as a nutritional supplement for athletes.

It comprises 61% of the amino acid pool in skeletal muscle. Glutamine’s 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.
