L-Lysine is an essential amino acid and must be obtained from food or by supplementation. Vegetarians and athletes who participate in frequent vigorous exercise are at highest risk for a lysine deficiency. Lysine helps the body absorb and conserve calcium and it plays an important role in the formation of collagen, a substance important for bones and connective tissues including skin, tendons and cartilage.*
