L-(+)-Ergothioneine is a naturally-occurring amino acid derived from histidine via hercynine. Ergothioneine is a stable antioxidant that scavenges and detoxifies free radicals and oxidants, increases intracellular thiol levels, controls nuclear factor-κB activation, and inhibits inflammatory gene expression. In addition, it inhibits the peroxynitrite-dependent nitration of nitrotyrosine, blocks oxidative DNA damage and cell death, and prevents the formation of xanthine and hypoxanthine. Ergothioneine is transported by the organic cation/carnitine transporter 1, which has been linked with autoimmune diseases, including rheumatoid arthritis and Crohn’s disease.

L-(+)-Ergothioneine is a natural molecule isolated from the rye ergot fungus and later identified in rat erythrocytes and liver and in numerous other animal tissues. Its antioxidizing properties may afford the compound therapeutic potential or it may be used as a food additive or in cosmetics.

L-(+)-Ergothioneine is a natural antioxidant, which has various physiological functions such as scavenging free radicals, detoxification, maintaining DNA biosynthesis, normal cell growth and cellular immunity.

L-(+)-Ergothioneine (ET) is a sulfur-containing amino acid, which is only produced by Actinomycetales bacteria and non-yeast like fungi belonging to the division Basidiomycota and Ascomycota. It was originally isolated from Claviceps purpurea or rye ergot. It is obtained from L-histidine, which is converted into betaine form called hercynine. It is found in both animals and plants, and mammals usually obtain it from their diet, e.g. through mushrooms or oats. It is tautomeric in nature, and in neutral aqueous solution exists in thione form.
