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.

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.

Pills too big
Does the job but they are huge! (pictured with a quarter for size reference) My biggest annoyance is that they don’t fit in my pill organizer with my multivitamins, etc.

Anxiety Reduced
I have bad anxiety when I drive places I don't know well. So my ex-girlfriend told me that her students w anxiety at her Howard County school take L-Lysine to help. So I said what the heck and found this huge value bottle and bought it. Does it work miracles? No. Does it take the edge off without affecting the monster in my pants, absolutely! I take this about an hour before a drive and I definitely notice a difference in the way I feel when driving. I don't even think about it while driving it's after I get there I realize - well, that wasn't so bad.

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.
