L-Lysine 90 Capsules

L-Lysine Supplement for Cold Sore Support, Collagen Synthesis, and Immune Defense

L-Lysine 90 Capsules by XYMOGEN is a targeted L-lysine supplement providing 1,000mg of L-lysine per capsule — the essential amino acid that plays critical roles in collagen production, calcium absorption, and immune defense against herpes simplex virus (HSV) reactivation. This 30-day supply supports adults managing cold sores, connective tissue health, or essential amino acid needs.

How L-Lysine Helps Manage Cold Sores and HSV

HSV reactivation is promoted by arginine — an amino acid that competes with lysine for intestinal absorption and cellular uptake. L-lysine supplementation raises the lysine-to-arginine ratio, reducing arginine availability for viral replication and decreasing the frequency and severity of HSV cold sore outbreaks. This mechanism is well-supported in clinical research.
