إل-لايسين

Haven't had a cold sore flare-up since I started these, and my energy feels steadier through the afternoon. The capsules are easy to swallow and don't leave any weird aftertaste, which is more than I can say for other amino acid pills I've tried.

I've been taking these daily for about three months now and the fact that it's an essential amino acid my body can't make on its own finally convinced me to stick with it. The capsules are easy to swallow and I haven't had any stomach upset, which was my main worry with supplements.

My doctor suggested I try an essential amino acid for immune support, and these capsules are easy to swallow with no aftertaste. I've been taking one daily for a few weeks now, and I feel like my body is getting the building blocks it needs.
