L-Lysine, 500 mg, 100 Capsules

I get cold sores occasionally and started taking lysine at the first sign — that early tingle stage. Genuinely surprised by how well it works. Outbreak either doesn't develop at all or is much milder and shorter than usual. I don't take it daily, just as needed at the first warning sign, loading up for a few days. Been doing this for a while now and it's become my first response — before anything else. No side effects, easy to swallow, good price per capsule on iHerb. If you're a cold sore sufferer this is worth trying.

I had to really search to find a capsule form of this. Tablets are usually huge and difficult to swallow. these are great. price is excellant. Swanson is the Cadillac of supplements and their prices are great. I have on repeating order.

Swanson L-Lysine offers an affordable, single-ingredient supplement delivering the essential amino acid L-Lysine. It's well-regarded for its role in supporting immune function and collagen synthesis. Many users take it to manage occasional cold sores, as lysine can counterbalance arginine. As a trusted brand, Swanson provides a cost-effective option for those seeking these specific benefits, ensuring purity and potency without unnecessary additives.

. But when we're under increased stress, our need for L-lysine increases even further. Our Free-Form L-Lysine capsules are a great way to meet the additional demands of high-stress times.

Lysine is alpha omega to take with collagen and vitamin c and I love this one. huge package and excellent quality with top ingredients. i can honestly really see the benefits in my skin already, it's much plumper ❤️

Thank you for providing such outstanding supplements! The quality is exceptional, with thoughtfully selected ingredients that offer remarkable health benefits. Your products have made a significant positive impact on my overall well-being. I also appreciate the secure and reliable packaging. Thanks again, iHerb!

My husband started taking this amino acid again. Along wih l- carinitine he has seen and felt a difference with his training. Difference in muscle and recovery time. Clean ingrediants and great value for money. The benefits so far are very noticible and energy as well.

I have been using l-lysine for many years and have noticed the benefits. This particular one has a nice package and no weird taste, the size is okay too.

Great quality L-Lysine at a good price. I use it to support skin and immunity, and it really helps keep cold sores away. Capsules are easy to swallow and gentle on the stomach. I’ll definitely keep buying this brand.

I’ve been taking L-Lysine for a couple of months now, and it’s become one of my favorite supplements. I originally tried it for immune support, and I’ve noticed I don’t get cold sores as often as I used to. Even when one does pop up, it seems to heal much faster. On top of that, my skin looks clearer and healthier, and I feel like my overall recovery from workouts has improved. The capsules are easy to take and gentle on my stomach—no side effects at all. It’s a simple supplement, but it really delivers. Definitely worth trying if you’re looking for natural support for immunity, skin, or recovery.
