NOW L-Lysine is a single-ingredient lysine supplement from a large, long-established supplement brand. Lysine is an essential amino acid the body cannot make, so it has to come from food or a supplement; it is used for protein production, collagen formation and calcium absorption. It suits people who want a plain amino acid supplement without added blends, and it competes with other single-ingredient lysine capsules and tablets on purity and brand reputation rather than on extras. Buyers rate it highly, though the listing gives no capsule count, dose or form details.

Buyers rate it very highly, and the few comments point to the brand and the simple single-ingredient formula as the reasons they keep buying.
L-Lysine is an essential amino acid. The body cannot make it, so it must come from the diet or from supplementation.
Lysine is needed to produce all protein in the body, including hormones, enzymes and antibodies. It is also needed to produce carnitine and collagen. Collagen is the structural protein that forms connective tissue such as skin, tendon and bone.
L-Lysine also plays a major role in calcium absorption. Some evidence suggests that supplementation may help support a healthy immune system and proper cardiovascular function.
