Lysine is used to balance someone's immune system when they have HSV1 or HSV2 (Herpes)...and if an outbreak seems to be on the way, higher dosing can keep it from happening...primarily cold sores (HSV1).

Great bargain

It's great I finally found a pill that's recommended dose in one pill. I've always had to take 2 pills so buying this was a money saver also.

Did wonders for cold sores!

It got rid of my frequent cold sores in days!
Pills are big, but went down. They are extra
strength so can be cut in half and last twice as long
(but double is good for cold sores). Love that it's healthier,
than most supplements, too!Read full review...
