I`ve been using L-Lysine 1000 mg from Solgar a few years now, and i believe it`s the number one L-Lysine brand, with evident quality. It prevents cold sore outbreaks. Started to use it when i read about a study which refers the imbalance of the aminoacids L-Lysine & L-Arginine as one of the main triggers of cold sore outbreaks (if the amount of L-Arginine is superior to L-Lysine because of an unbalanced diet). For those with very often outbreaks, it helps cutting with chocolate, caffeine, peanuts, nuts e other seeds with high amounts of L-Arginine. Nuts can have 5000 mg of L-Arginine ! A huge trigger for someone with frequent cold sore outbreaks.

Works good for me for the immune system. If the tablet is too big to swallow you can easily chew it.

Didn't give it 5 stars well, because I haven't been using it for long, but my skin seems to be getting nicer and I didn't get any coldsores, even though it's the depth of winter right now, so yey!

I give it a four, just because the pills edges are so tough to tolerate. Otherwise, it has served me well and done its job. My skin appears so much healthier and others have even commented on it.
