Ergothioneine (EGT) Natural Antioxidant & Cellular Protection

High-Purity Ergothioneine (EGT) Antioxidant Ingredient

Ergothioneine (EGT) is a rare, naturally occurring chiral amino acid with exceptional antioxidant and cell-protective functions. Chemically known as 2-thio-L-histidine trimethylbetaine, EGT is a powerful natural antioxidant featuring a unique thione–thiol tautomeric structure that provides outstanding stability against oxidation. Unlike other antioxidants such as glutathione, EGT remains stable under physiological pH, offering long-lasting cellular protection.

Humans cannot synthesize Ergothioneine and must obtain it externally, making it a vital micronutrient with diverse health benefits. Produced with advanced fermentation and purification technology under ISO22000, HACCP, and FDA standards, our EGT features ultra-high purity, excellent bioavailability, and consistent quality suitable for food, pharmaceutical, cosmetic, and nutraceutical applications.
