Terrific product. I have suffered from cold sores my whole life. I am over 45 and have been taking L-Lysine for about 10 years. It works. If I catch a cold sore early, it doesn’t emerge if I take L-Lysine. At the onset of a tingle, I take two in the morning, one in the afternoon, and two before bed. I do this for as long as I feel the tingle and two days after it stops. This product is fantastic! They do cause some constipation, so drink plenty of water with them.
