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

Lysine powder

Posted by iHerb Customer on Dec 12, 2017 | Verified Purchase

Arrived well packaged and fresh. Haven't used it long enough to have an opinion as to efficacy.

Thanks for your feedback!

Bought for cats' health, really.

Posted by iHerb Customer on Dec 03, 2017 | Verified Purchase

I read that this is good to give cats to keep them healthy in winter. It is also for humans, and because it is vegan, I can take it too. A large pot for a reasonable price, this will last for ages.

Thanks for your feedback!

Very economical

I like it okay

I put this lysine powder in with my argnine powder and some powdered glycine, and it takes away the nasty taste of the arginine. Works great!! You're suppose to use lysine with arginine anyway, because arginine uses it up, and then you are susceptible to the herpes virus that causes cold sores. I've read that this is also very good for osteoporosis, as it helps the body utilize calcium better. This bottle lasts a long time. Great buy.
