I recently started taking protein powder and developed cold sores. I have since learned protein powder contains Arginine which can cause cold sores to develop. Now, I've added Lysine supplements which is supposed to help counter against the Arginine. I did, however, always know that the cold sores were herpes and they are unpleasant.
