Many folks eat high lysine foods prior to or during a cold sore event, and avoid high arginine foods. For many folks, healing cold sores fast has been as simple as taking 1,000 milligrams to 3,000 milligrams of lysine in capsule supplements during an outbreak. High lysine foods to eat are most meats and dairy products.
Treatment may get rid of the cold sores only 1 to 2 days faster, but it can also help ease painful blisters or other uncomfortable symptoms. The herpes simplex virus that causes cold sores can't be cured. After you get infected, the virus stays in your body for the rest of your life.
