L-Lysine

Helps reduce the recurrence of herpes simplex virus (HSV) infection Provides lysine, an essential amino acid that maintains good health Provides lysine, an essential amino acid that maintains good health. The essential amino acid L-lysine cannot be synthesized by the body and must be obtained from the diet. It is best known for its ability to reduce the recurrence of infections caused by the herpes simplex virus (HSV), which primarily affects the skin and mucous membranes. Since HSV requires arginine to replicate, lysine plays an important role in maintaining the health of gums and lip tissue. Lysine competes with arginine for transport into cells and reabsorption in the kidneys, increasing arginine excretion. It also stimulates the activity of arginase, an enzyme responsible for breaking down arginine. Studies suggest that lysine supplementation significantly reduces the frequency of HSV recurrences, including cold sores. Additionally, a randomized, placebo-controlled trial demonstrated that lysine reduces the occurrence, severity, and healing time of recurrent infections.
