Everyone has a favorite was to fight nasty cold sores. But, did you ever think of fighting them from within? Try taking the vitamin supplement L Lysine. It is an amino acid that builds collagen and is used for tissue maintenance. I call them little miracle workers. Start taking as soon as you feel the itch hot spot of an incoming fever blister. Use it in combination with your usual topical brand of cold sore medicine.
Tip: Follow the directions for use on your own bottle.
