2. Lysine

Lysine is a natural supplement that can decrease the frequency of cold sore outbreaks and speed up the healing process. Avoid taking high doses of lysine for long time, and take the supplement cautiously if you have high cholesterol levels or heart disease. You can safely increase the amount of lysine in your diet by adding more lysine rich foods like fish, chicken and eggs.
