99.9%+ VERIFIED PURITY | NO SYNTHETIC FILLERS | NATURAL INGREDIENTS ONLY. Most ergothioneine supplements don't publish their purity standard. Ours does — 99.9%+ verified by independent third-party testing. Natural fillers only: organic tapioca starch, acacia gum, rice flour, vegetable capsule. No magnesium stearate. No silicon dioxide. No synthetic flow agents.
GETS INSIDE YOUR CELLS — WHERE OTHER ANTIOXIDANTS CAN'T REACH. Most antioxidants work in your bloodstream and never make it inside your cells. L-Ergothioneine has its own dedicated cellular transporter — actively pulled inside your cells to protect your mitochondria and DNA directly. That's why it concentrates in your brain, heart, and liver.*
