My daily go-to to keep cold sores under control
I’ve had cold sores since I was a kid, and they can be really painful whenever stress hits. I started taking this Lysine supplement daily, and it’s made a huge difference for me. When I’m consistent with it, I hardly ever get flare-ups, and if I do, they’re much smaller and heal faster. I like that the tablets are easy to take, the bottle lasts a long time, and it’s affordable compared to some of the other brands I’ve tried. It’s become part of my daily routine now — a small habit that’s helped me feel more confident and in control, especially when life gets stressful.

Experts recommend resveratrol for healthy heart. I bought this because I don’t trust India brands making the same product. It has suit me well. USA made. I have had no side effects. Combine it with ashwagandha tablets to manage stress.
