excellent

I love the quality of the ingredients. The size of capsule is easy to swallow. There is not any smell or after taste. It is nice for my skin and I take it in the morning before training. I want to have more strong muscles so it is necessary to take enough protein.

Life extension l-lysine

I have a tendency for an occasional winter cold sore. When I am consistent in taking one a day I don’t get an annoying cold sore. My chiropractor told me to take this to eliminate them and it works. I’m happy with this product

L-lysine is my go to supplement when I feel like Im coming down with a cold and immune system needs support. I'm not sure why Life Extension went with 620 mg...so I take 2 capsules for more benefits. This amino acid can be a bit stimulating (energizing), so I take it in the morning on empty stomach or sometime after breakfast, if my stomach is upset.

High Quality and Smooth to Take

This is a clean and reliable lysine supplement. The capsules are a good size and easy to swallow, and I appreciate that there aren’t any unnecessary fillers. The dosage per capsule is convenient for daily use, and the bottle comes with plenty of servings for the price. After adding it to my routine, I noticed a more balanced overall feel during the day. Overall, solid quality and consistent results.

Fight the Cold Sores

I always have a bottle of L-Lysine on hand as a cold sore preventative / remedy. This is the first time using the Life Extension brand, but is just as effective as all the others.
