Evidence Summary
Lysine is particularly important in the creation of carnitine, which converts fatty acids into energy and also lowers cholesterol levels. It also seems to play a role in absorbing calcium and helps the body form collagen, which aids in the growth and maintenance of bones and connective tissue (including skin). The most commonly practiced use of L-lysine is in the treatment of the herpes simplex virus, but it has various mechanisms and variations through which it may be able to fight cancer, reducing tumour size and causing cell death in cancer cells without damaging nearby healthy cells.
