Mega L-Ergothioneine, 30 Vegetarian Capsules

I’ve recently upgraded to Mega L-Ergothioneine (25 mg) and I absolutely love it. This stronger strength feels like the premium version of what I already liked about the regular form — cleaner support, deeper antioxidant protection, and just a more solid “feel” in my wellness routine. The quality is clearly high (gluten-free, non-GMO, vegetarian) and the branded ErgoActive® form gives me confidence. I’ve noticed subtle but meaningful differences: better resilience, a calmer internal environment, and a general sense of being better protected from oxidative stress. If you’re looking for next-level support rather than just a basic dose, this one hits that mark. This is one of those supplements I enjoy taking because it feels like a meaningful upgrade. Highly recommend if you’re ready to invest in a strong antioxidant step.

I added Mega L-Ergothioneine from Life Extension to my routine mainly for long-term health support, and I’ve been happy with it so far. It’s not something you “feel” immediately, but over time I’ve noticed a more stable sense of energy and better overall resilience, especially during busy or stressful periods.

I'm really happy with this supplement! The quality is top-notch, and I can tell it's made with care. I've been taking it for a while now, and I feel like it's making a positive impact on my overall health. Would definitely recommend!

Healthy aging support. Contains both L-ergothioneine (mega dose of 25 mg) and vitamin C. Both help neutralize reactive oxygen species and protect cells from oxidative stress.

It's not bad, don't really feel anything either way, but this product is positioned for long term health benefits, not acute. No bad side effects which is a plus. The quality is fine. Uniform white powder color.

Bought to help my eye health. I read studies that suggest it is good for eyes, and as I have Glaucoma, I thought it was worth trying. Not the kind of supplement that has immediate, noticeable effects, but it is a good high dose of L-ergothioneine and is easy to take, just 1 powder capsule a day. Bought 3 bottles to really give it a go. So far no side effects, no taste or after-taste. iHerb always seems to have the best price too.

i like the regular dose that's why I bought this to try. it sud be the same quality and same ingredients. but i feel the regular dose ergothioneine made me more comfortable and relax. will compare more

I have included Life Extension’s Mega L-Ergothioneine in my nutritional protocol as a high-end dietary supplement for cellular protection. This specific amino acid is fascinating because humans have a dedicated transporter for it, making its bioavailability a key factor for those on a clean, plant-based diet.
