    Ergothioneine (Cas 497-30-3) Usage


    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.


    We use fermentation technology in the manufacturing process. The ergothioneine fermentation broth is crudely extracted, purified and crystallized to obtain high quality ergothioneine products. 

    The ergothioneine product obtained by this process has a purity of over 99% no obvious odor (0.1% solution).
