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.

Seems to do the job.

I've used it before and will continue to do so in combination with L-Proline and vitamin C to clean up arterial plaque as suggested by Dr. Linus Pauling.

Thanks for your feedback!

L-Lysine 1000mg

I haven't been taking this product long enough to know if it has made a change to my health, but it gives me terrible heartburn. I stopped taking it for a few days and the heartburn stopped. I started again and the heartburn started again, it gave me a terrible pain in my gut.

Thanks for your feedback!

Huge pill size

I haven't noticed any negative side affects, but also didn't notice any improvement in my skin (I heard it could help with hormonal acne) but I haven't taken it consistent enough to make a conclusion. I have a hard time taking this pill because I'm not use to this size.
