I'm so grateful someone told me about this dosing trick for L-Lysine and cold sores. I've struggled with cold sores for years and at one point, took Lysine on a regular basis to keep them at bay. But, the trick is to take it only when they crop up, and to use the correct dosing. It works like a charm (at least for me and everyone else I know that has tried it!). Hope it's helpful for you too!
Here's the dosing:
L-Lysine, 500 mg
As soon as symptoms start (burning, redness, blisters), take 3 capsules. Take 2 capsules the next day, then take one capsule every day thereafter until cleared.
