L-Ergothioneine Structure

Synonyms: Ergothioneine, L-Ergothioneine, Ergothioneine (EGT), (S)-α-Carboxy-2,3-dihydro-N,N,N-trimethyl-2-thioxo-1H-imidazole-4-ethanaminium inner salt, Thiohistidine betaine, 2-Mercaptohistidine trimethylbetaine, EGT, L-(+)-Ergothioneine

Ergothioneine (EGT) is a naturally occurring amino acid derivative and a potent antioxidant with unique properties. It is synthesized by certain fungi, actinomycetes, and cyanobacteria, and is accumulated in the human body through dietary sources, particularly mushrooms (especially shiitake and oyster mushrooms), black beans, and organ meats. Humans cannot synthesize ergothioneine endogenously, making it a conditionally essential nutrient.

Ergothioneine is distinguished from other antioxidants by its specific transporter, OCTN1 (SLC22A4) , which actively transports EGT into cells, enabling its accumulation at high concentrations in tissues exposed to high oxidative stress, including the liver, kidney, red blood cells, and the lens and retina of the eye. This targeted accumulation, combined with its powerful free radical scavenging activity and its ability to chelate metal ions, provides robust protection against cellular oxidative damage.

Ergothioneine is widely used in dietary supplements, functional foods, cosmetic formulations, and research applications targeting healthy aging, neurological health, skin protection, and cardiovascular support.
