Product Information

One of the best nutritional treatments for the Herpes simplexvirus is L-Lysine, a well-known amino acid. L-Lysine is one of the nine essential amino acids that the body needs to manufacture proteins. It is considered "essential" because the body cannot manufacture L-Lysine.

As an amino acid it is involved in tissue repair, production of hormones and enzymes and in the synthesis of collagen and bone health. Most persons get adequate L-Lysine in their diet but those who have problems with the herpes virus may need supplemental L-Lysine to keep the virus in check.

This approach originally came from research showing that lysine has anti-viral activity against the Herpes simplex virus in test tube studies. L-Lysine works to inhibit the growth of the virus by blocking its use of another amino acid - arginine.

In order for L-Lysine therapy to really be effective in preventing cold sores and outbreaks of genital herpes it is important that the diet also is low in arginine. Avoid foods high in arginine like chocolate, peanuts, almonds and other nuts, and seeds. It is also a good idea to focus on foods that are high in L-Lysine such as most vegetables, legumes, fish, turkey, and chicken. Follow these dietary guidelines and take one gram of L-Lysine three times daily with meals for maximum benefit. In one double-blind study, after 6 months, L-Lysine was rated as effective or very effective in 74% of cases compared to only 28% for those receiving the placebo.

L-Lysine also plays a role in helping the body to absorb and conserve calcium, so it may also be important for those who have a predisposition to osteoporosis.

L-Lysine should be an essential part of a nutritional protocol to prevent flare-ups of the herpes simplex virus, in whatever form it may take. Combine therapeutic dosages of L-Lysine with a low-arginine diet and extra nutritional help from vitamin C and zinc for effective control of this virus.

Feels good on the skin not greasy
Size: 1.3 Fl Oz (Pack of 1)
Very nice product very concentrated has a very light fragrance that dissipates very quickly not greasy. No I do not have any redness or sensitivity I wanted to try this product anyway because I'm always looking for moderately priced good quality that travels well. And this fit the bill especially with it being on sale.

Good product , but
Size: 1.3 Fl Oz (Pack of 1), Size: 1.3 Fl Oz (Pack of 1)
It seems to be a good product and it’s not too heavy , but still caused few breakouts here and there . Also, Avenue always has protective foil on their cream , this one didn’t have (I replaced it but new one also didn’t have it). Also, it goes away really fast because it’s only 1.3 ounces.

Gold Star
Size: 1.3 Fl Oz (Pack of 1)
This cream is truly gentle and healing for a compromised skin barrier. I prefer this cream in the winter, when the weather is dry, and after procedures like microneedling or laser. It has never irritated my skin, and does soothe and heal. The La Roche Posay cicalfate cream is also excellent, I think it is slightly less rich, so I prefer that in humidity or the summer.

Overpriced but it works.
Size: 1.3 Fl Oz (Pack of 1)
I hate that I love this product. It's stupid expensive. But it's great for broken/damaged/recovering skin. I've used it post microneedling and it is the only thing that soothes, hydrates, and doesn't sting raw, red skin. Great for rashes/hives and allergic reactions too. Luckily a thin layer is often enough to do the trick. so it lasts a long time I wouldn't use for everyday moisture, but when your skin is angry, this stuff works. (Overpriced? Yes. Witchcraft? Maybe. Does it work? Yep.)
