How It Works
Cold sores don't disappear — they lie dormant in your nervous system, waiting for a trigger. Stress, illness, your menstrual cycle, and foods high in L-Arginine (like chocolate, nuts, and red meat) can all signal the virus to reactivate.
Cold Sore Shield's proactive formula is built to work with your body's immune system around all of these triggers. Rather than treating an outbreak after it starts, this daily supplement is designed to support the immune environment that keeps the virus in check — so you're protected when it counts most.*
Take daily for best results, or begin a few weeks before any high stress enviroment where you've experienced outbreaks in the past.
