Large size, good quality
I was told by a physician that this helped to ward off canker sores. I have been using it for years. But other brands are hard pills. This one is a capsule. It’s a good strength so you don’t have to take multiple pills. It’s a value pack. It’s really effective.

Great product for the money
I like the health benefits of these. The pill isn’t too big, pretty easy to swallow. The strength is 1000mg, which is perfect for me. Great value price point too.

Simple amino acid, huge difference—I feel it in immunity and comfort
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.

Helps My Skin
I have been taking for about three years now, and I think these are what are a contributing factor for clearing up my skin and making it look healthier. Prior to taking these, I would get horrible cystic acne, now it’s very rare, maybe once a year. They are easy to swallow and no bad taste.
