L-Glutamine has become increasingly popular as new studies reveal its unique contribution to protein synthesis, muscle growth, anti-catabolic (prevents muscle tissue breakdown) function and growth hormone elevating effects.

Glutamine provides a critical link in muscle metabolism not shared by any other single amino acid.

USN's L-Glutamine powder is pure, pharmaceutical grade 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 compromises 61% of the amino acid pool in skeletal 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 remarkably after training and remain low until complete recovery.
