How It Works
How It Works
L-Lysine competes with arginine, which the herpes simplex virus needs to replicate. By maintaining higher lysine levels, you help keep the virus dormant and reduce outbreak frequency. As an essential amino acid, it also supports your body's natural tissue repair and collagen synthesis processes.
Who It's For
Adults who experience recurring cold sores or want to prevent herpes simplex outbreaks. Vegetarians and vegans who may not get adequate lysine from food sources. People following restricted diets or those looking to support their immune system health.
Who It's Not For
This product isn't necessary if you already consume adequate lysine through a varied diet rich in protein sources and don't experience cold sore issues.
About This Product
Natural Factors L-Lysine capsules supply 500 mg of free-form L-lysine each, in a vegetarian shell. Helps in collagen formation.
What is L-lysine?
Lysine is one of the nine essential amino acids. The body cannot build it from other nutrients, so all of it has to come from food or supplements. Meat, fish, dairy and legumes are rich sources, while most grains provide relatively little. In this product the lysine is supplied as L-lysine hydrochloride, a stable salt, and is not bound up in a larger protein.
Key features

Why supplement with lysine?
Lysine is one of the amino acids found in collagen, the structural protein of tendons and other connective parts of the body. People who eat mostly grain-based or plant-based meals may get less lysine from their diet than people who eat meat, fish or dairy.
