L Lysine is an essential amino acid; therefore it must be obtained from the diet as the body cannot produce it on its own. L Lysine has long been considered an excellent treatment for the prevention of cold sores and, in more recent years, has been attracting attention as an excellent addition to the already long list of mass building nutrients. L Lysine is an essential building block for all protein in the body and also plays a major role in: calcium absorption, building lean tissue, recovering from surgery or sports injuries. L Lysine supplementation has been shown to increase the absorption of calcium. Lysine also works with other essential amino acids to maintain growth, lean body mass, and improve the body’s store of nitrogen.
