L-Ergothioneine (EGT) is a naturally occurring, sulfur-containing amino acid derived from histidine, with the chemical formula C9H15N3O2S and a molecular weight of 229.30 g/mol . First discovered in 1909 by Charles Tanret in the ergot fungus Claviceps purpurea, this compound has intrigued researchers for over a century due to its unique chemical properties and potent biological activities.

L-Ergothioneine is a unique, stable, and potent antioxidant with a specific transporter system that enables its accumulation in tissues prone to oxidative stress. While its in vivo physiological role remains an active area of investigation, substantial evidence supports its cytoprotective effects and safety. It is widely used in dietary supplements and cosmetic formulations, particularly for skin protection against UV-induced oxidative damage.
