Cold Sore

Cold sores are itchy and painful blisters that form around the lips and nose. They are caused by the herpes simplex virus and can often be quite uncomfortable, and for some people, embarrassing. Whilst most cold sores can disappear on their own over time, there are several supplements that can help reduce their severity and prevent their onset. Antiviral creams are good when cold sores occur, as is the amino acid Lysine when applied directly to the blister. Daily consumption of a Lysine supplement can help prevent the formation of new cold sores. Look to take between 500-1000mg daily.
