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.

iHerb Customer Reviews

good value

Posted by iHerb Customer on Nov 17, 2017 | Verified Purchase

Good product. good value. our vet recommended lysine for our young cat who contracted herpes as a young kitten{she was a rescue so didn't know till she was vet checked}. She needs to be on this for life to keep it at bay and stop flare ups and it works. She needs 250mg twice a day so has half tablet crushed with her food twice a day and she eats it no problem. So this product having 250 tablets is economical for us. recommend. will keep buying.

Thanks for your feedback!

Must have

Posted by iHerb Customer on Mar 17, 2017 | Verified Purchase

I've been using L-lysine for years to prevent and cure shingles outbreaks. I don't know for sure, but I believe it helps alongside with zink, vitamin D, and a healthy diet and lifestyle. I take 500-1000 mg on a daily basis, and 1500-2000 during outbreaks. I also recently started taking Olive Leaf Extract, which I read can kill the herpes virus, and is also a good immune support.

Thanks for your feedback!
