Description and Uses
L-Threonine is used to alleviate anxiety and mild depression. It is an important component of many proteins such as tooth enamel, collagen, and elastin. It is an important amino acid in the nervous system and plays a vital role in porphyrin and fat metabolism. It is useful in intestinal disorders and indigestion. It is also used as a prodrug to reliably elevate brain glycine levels.
