L-Lysine from Webber Naturals is one of the best-known nutritional supplements for treating cold sores caused by the Herpes simplex virus. L-Lysine is one of nine essential amino acids needed by the body to manufacture proteins. It is called "essential" because the body cannot manufacture it.

L-Lysine is involved in tissue repair, production of hormones and enzymes, and in the synthesis of collagen and bones. 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. Laboratory research into lysine's anti-viral activity indicates that it may inhibit the growth of the Herpes simplex virus by blocking the virus' use of arginine – another amino acid. Foods are high in arginine – like chocolate, peanuts, almonds and other nuts, and seeds – and should be avoided if you want to prevent cold sores.

Experts recommend combining therapeutic dosages of Webber Naturals L-Lysine with a low-arginine diet and extra nutritional help from vitamin C and zinc for effective control of the herpes simplex virus.
