Jacob ★★★★★

Started these after my dermatologist suggested lysine for cold sore flare-ups, and I've had way fewer of them this winter. The 1000 mg dose means I only take one capsule, which is easier than the old 500 mg tabs I used to swallow two of.

Hazel ★★★★★

I've been taking these 1000 mg capsules daily for about two months now, and the difference in how I feel is noticeable. Each tablet is easy to swallow and the bottle lasts a good while at one a day.

Charlotte ★★★★★

My cold sores used to show up every few months, but since taking one of these 1000 mg tablets daily, I've barely had a tingle. The tablets are easy to swallow and don't leave any aftertaste, which I appreciate.
