Lysine is an essential amino acid with a well-documented role in cold sore prevention. The herpes simplex virus (HSV-1) requires arginine — another amino acid — to replicate. Lysine and arginine compete for the same absorption pathways, so maintaining a high lysine-to-arginine ratio in the body suppresses viral replication and reduces the frequency and severity of cold sore outbreaks. Quantum Health's "Super Lysine Plus" formula builds on this foundation with immune-supporting cofactors. Key Benefits Cold Sore Prevention: High-dose lysine suppresses arginine availability — the primary fuel HSV-1 uses to replicate — with multiple clinical trials showing significant reduction in cold sore frequency and healing time Immune Support Blend: "Super" formula pairs lysine with additional immune nutrients including vitamin C, zinc, and echinacea — addressing both the viral suppression and immune response sides of cold sore management Collagen Support: Lysine is essential for collagen cross-linking — supports skin integrity, wound healing, and tissue repair Convenient Tablet Format: 90 tablets — ideal for maintenance dosing during periods of stress, illness, or sun exposure (common cold sore triggers) Ingredients: See image
