Threonine is an essential amino acid that cannot be synthesized for use in mammalian tissues. Because of this, a dietary supply of threonine must be achieved on a daily basis to regulate and maintain proper protein balance within the body. Threonine is an important component of many proteins found in the human body and is needed for the formation of such protein rich tissues as collagen, elastin, and tooth enamel. [1] The heart, central nervous system, and skeletal muscle provide the highest concentrations of this essential amino acid.

A precursor to glycine and serine, threonine also provides the body with a mild glucose sparing effect, assisting in the stabilization of blood sugars via gluconeogenesis in the liver. Nutrients consumed by diet are more readily absorbed when threonine is present, aiding in both its metabolism and assimilation. Threonine may also prove therapeutic when combined with the branched-chain amino acids valine, isoleucine, and leucine.
