Threonine is an essential amino acid that promotes normal growth by helping to maintain the proper protein balance in the body. Threonine also supports cardiovascular, liver, central nervous, and immune system functions. Threonine is needed to create glycine and serine, two amino acids that are necessary for the production of collagen, elastin, and muscle tissue. Threonine helps keep connective tissues and muscles throughout the body strong and elastic, including the heart, where it is found in significant amounts. It also helps build strong bones and tooth enamel, and may speed wound healing or recovery from injury. Threonine combines with the amino acids aspartic acid and methionine to help the liver with lipotropic function, or the digestion of fats and fatty acids. Without enough threonine in the body, fats could build up in the liver and ultimately cause liver failure. Threonine supports the immune system by aiding in the production of antibodies, and because it is found largely in the central nervous system.
