L-Lysine is an essential amino acid, which means that is cannot be manufactured by the body and must be obtained through the diet or by supplementation. Lysine is necessary for the production of all protein in the body including hormones, enzymes, and antibodies, as well as carnitine and collagen, which is the structural protein forming all connective tissue such as skin, tendon, and bone. L-Lysine also plays a major role in calcium absorption. Some evidence suggests that L-Lysine supplementation may help to support a healthy immune system as well as proper cardiovascular function.

Good immune booster

Posted by 5551886917147044888 on Dec 05, 2016

When I start feeling super run down I take this on an empty stomach every few hours for one or two days, and it helps me bounce back quicker. The only downside to this product is that the tablets are quite large. It's okay for me, but you'll definitely want to choose a smaller dose if you have any trouble swallowing pills.

Huge Hard to Swallow

Posted by Reviewer3301351 on Nov 21, 2016

In error thought I was ordering GEL "CAPS "' but CAPs are huge hard cap shaped pills -- very difficult to swallow. Even if Lysine may be good quality, not very "bio-available"!
