What is L-Lysine?
L-Lysine is an essential amino acid that your body cannot produce--it must come from diet or supplements. It's crucial for protein synthesis, hormone and enzyme production, calcium absorption, and collagen formation.
Cold Sore Prevention
Lysine's most popular use is preventing and treating cold sores caused by herpes simplex virus. Lysine competes with arginine, which the virus needs to replicate. Supplementation may reduce outbreak frequency and healing time.
Collagen Production
Lysine is essential for collagen synthesis, making it important for skin, wound healing, and connective tissue health. It helps convert lysine residues in collagen to hydroxylysine, strengthening the collagen structure.
Calcium Metabolism
Lysine helps the body absorb calcium and reduce calcium loss in urine. This may benefit bone health, particularly when combined with adequate calcium intake.
Dosage
For cold sore prevention: 500-1000 mg daily. During outbreaks: 1000-3000 mg daily. Lysine is most effective when combined with a low-arginine diet.
