Cold sores and HSV-1 nutritional supplements

User Profile
ummm... odd question. hopefully this is the correct section for it. i recently purchased an overpriced nitric oxide supplement for bodybuilding. i began taking the supplement after briefly scanning the bottle for directions, etc... today i got looking at the bottle and it warns against taking it if you have a history of cold sores (and I do) what the heck is this all about?? should i stop taking it??

A cold sore is a small painful blister on or near the lips, or sometimes the nose, caused by the virus Herpes simplex type-1 (HSV-1). Nitric oxide increases blood circulation in the muscles which is important for supplying the muscles with nutrients in order for them to work and build muscle mass. I'm unable to produce any data about nitric oxide's influence on people with HSV-1 infection but you might consult the producers of the supplement to ask why the supplement is contraindicated for people with HSV-1.
