L-Threonine is an essential amino acid. It is found in eggs, milk, gelatin, and other proteins. It’s important for the nervous system, threonine also plays an important role in porphyrin and fat metabolism and prevents fat buildup in the liver. Useful with intestinal disorders and indigestion, threonine has also been used to alleviate anxiety and mild depression.
