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.
