Lysine is an essential amino acid that must be obtained through diet or supplementation.
Lysine is necessary for the production of all proteins in the body and is necessary for the maintenance of the structural proteins collagen and elastin, which form all connective tissues such as skin, tendon and bone.
Lysine is also a precursor to carnitine, which is necessary for fat metabolism and energy production. Additionally, lysine may help maintain a healthy immune system and proper cardiovascular function.
