Ergothioneine(CAS 497-30-3)Anti-inflammatory,Anti-aging API

Ergothioneine (EGT) is a naturally occurring, diet-derived amino acid and a highly potent, stable antioxidant. Unlike traditional antioxidants, humans possess a highly specific transporter protein (OCTN1) dedicated to drawing EGT directly into the cells, particularly those under high oxidative stress. Widely regarded as a “longevity vitamin,” EGT has become a blockbuster ingredient in both premium skincare formulas and longevity supplements for its unparalleled cytoprotective (cell-protecting) properties.
