L-Ergothioneine: The Longevity Vitamin Your Body Can't Make

Sale price  $24.99 Regular price  $37.95 / 25mg | 30 Capsules

Most antioxidants your body makes on its own. This one it can't.
Ergothioneine comes only from your diet — trace amounts in mushrooms and a few other foods — yet your cells build a dedicated transporter just to capture and hold onto it. That's the body's way of flagging a molecule it treats as worth protecting, and it's why most people don't get nearly enough.
MyGevity L-Ergothioneine delivers a clean 25mg dose at 99.9%+ purity to help fight oxidative stress and protect your cells from age-related damage.* Every capsule is physician-formulated, third-party tested, and made in a GMP-certified U.S. facility — 100% vegan, non-GMO, gluten-free, and free from seed oils and artificial fillers.*
