Ergothioneine (2-mercapto-L-histidine trimethyl inner salt) is a natural amino acid derivative with chiral properties, widely found in animals and plants. Humans cannot synthesize ergothioneine, but after ingestion through food, the body's cation transport protein OCTN1 helps absorb and accumulate it in large quantities. As a natural antioxidant, ergothioneine effectively scavenge free radicals, playing an important role in human physiological activities and showing broad application prospects.

Efficacy: Protects the nervous system, enhances memory, protects the cardiovascular system, and is a food antioxidant.
