Product Description

    Ergothioneine (2-mercaptohistidine trimethylendolide, L-Ergothioneine, EGT) is the only known natural 2-thioimidazole amino acid (2-thioimidazole). EGT has an absorption wavelength similar to DNA in the UV absorption range, which can effectively protect against UV damage. EGT has a strong antioxidant capacity and can inhibit the formation of various oxidation active substances. In addition, EGT is chemically stable, can accumulate in the epidermal cells of the skin belly and is non-toxic.

    L-(+)-Ergothioneine is a natural antioxidant and amino acid derivative found in various organisms, including fungi, plants, and some bacteria. L-(+)-Ergothioneine acts as a potent antioxidant, protecting cells from oxidative stress by scavenging free radicals and reactive oxygen species. It is believed to play a protective role in cells and tissues, particularly those exposed to high levels of oxidative stress, such as skin cells and certain organs. L-(+)-Ergothioneine is primarily obtained from dietary sources, especially mushrooms (such as shiitake and oyster mushrooms), as well as from some plants and microorganisms. Research suggests that ergothioneine may have potential health benefits, including anti-inflammatory properties and protective effects against various diseases linked to oxidative damage. Due to its antioxidant and potentially health-promoting properties, L-(+)-Ergothioneine is being studied for use in dietary supplements, skincare products, and pharmaceutical applications.
