Customer Ratings & Reviews

As someone who is sensitive to cold sores, I find that the combination of L-lysine and vitamin C helps to protect against cold sores. In the very rare occasion that I do get one, it's much less intense and heals quicker. L-lysine + vitamin C also promote the formation of collagen, which is essential to maintain healthy, youthful skin.

Great! I bought it for my cats which one of them is having a herpes, it seems to imprive her health as it helps form all connective tissue such as skin, tendon and bone, and also functions as an immune system booster. A vet recommended me giving her 1 capsule a day, I simply open it and mix it with a wet food she loves. I also use it on myself when my skin has to heal from something, a wound, a cut or recover from a little surgery, or even a cold, and it also improve my hair elasticity.

Whenever I feel the tingle of a coldsore coming on I make sure I start taking or upping my l-lysine maintenance dose (1 cap a day). When I have a breakout I take 2-3 caps a day and it helps to quell the longevity and severity of the coldsore. L-lysine is a natural anti-viral, so is a perfect thing to have in your coldsore/viral toolkit. Jarrow always makes high quality products, this is no exception. Pills are easy to swallow with no smell or taste. Tip: if you do have a coldsore make sure you’re also eating a diet high in l-lysine and low in l-arginine!

I have been using the products of this brand for a long time and with great pleasure. I like the quality and proven ingredients very much.

I use 2 capsules every morning with water, and it has benefitted me greatly, it reduced the amount of cold sores I get, which is such a horrible feeling, thus I'm super happy with this supplement. I haven't had a cold sore in months now, and when I had just started taking these I did get one and swallowed some extra Lysine at night, prior to sleep. That helped me get rid of the existing cold sore more quickly.

Great price. I enjoy Now products so I trust this will do the job. I usually use the vimergy which you can't get on here anyway, and it got rid of my husbands worts on his feet in just a few months. Its good for any herpes zoster virus including shingles. I will update if it doesn't work.

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. Lysine is also a precursor to carnitine, which is needed for fat metabolism and energy production. In addition, lysine may help to support a healthy immune system and proper cardiovascular function.

I used to get cold sores all the time, until I found out about lysine. I take 3 a day with vitamin c on an empty stomach and have not had a cold sore or a cold in years. If you feel a cold coming on you can triple the dosage and it never comes. This is a large bottle that lasts a long time. Great brand with speedy delivery from iHerb.
