Nutricost L-Lysine 1000mg Per Serving, 250 Servings, 500 Capsules - Gluten Free, Non-GMO, 500mg Per Capsule

I have used this brand for years and it works so well on cold sores, sore throats, any little infections. Highly recommend if, for example, eating corn on the cob makes your mouth swell.

This is the only brand I order. We take it every day for autoimmune issues. Doesn't bother my Mast Cell. Great price, ships fast. Doesn't make you burp after!

Easy to take capsules that work well for prevention of canker sores in my mouth. This is the second time ordering this brand.

As someone who’s always curious about how small lifestyle tweaks can support overall wellness, I decided to try Nutricost L‑Lysine 1000 mg (500 capsules, roughly 250 servings). I’ve been taking it consistently for a few months now, so here’s what I’ve discovered from daily use. ✅ What stood out to me: Straightforward formula, real value: It’s just pure L-lysine paired with a clean capsule shell—no fillers, non-GMO and gluten-free. I appreciate knowing exactly what I’m consuming without guessing from a long ingredient list. Improved immune resilience: I tend to get minor cold symptoms during high-stress periods or travel, but since starting this supplement, I’ve noticed fewer outbreaks—especially around the mouth (cold sores). It’s subtle, but consistent. Easy to manage daily: I take two capsules with breakfast. The bottle lasts roughly 4–5 months at my pace—convenient to reorder before I’m close to finishing. 🏁 Would I recommend it? Yes, if you want a simple, plant-based amino acid supplement to support immunity and wellness routines—not as a replacement for medical care, but as part of your holistic toolkit. Skip it if you're allergic to gelatin (capsule material) or expect immediate dramatic effects. Patience and consistent use are key.

came quick, big bottle, easy to swallow capsules. four stars for now just purchased

Take it every morning. Good product.

Just what I ordered. Good Value!

Finally a canker sore treatment that works. If I feel one coming on I usually take 3000mg once a day and that cuts down the duration and pain. Very pleased with the results.
