L-Ergothioneine  | CAS:497-30-3 | Nutritional supplements

L-Ergothioneine (EGT), a rare natural chiral amino acid, is a rare chiral amino acid antioxidant existing in nature. It was originally found in mushrooms and cyanobacteria and widely distributed in mammalian cells and tissues.

Because of its strong oxidation resistance and natural safety, ergothionine can be used in food, health care products, cosmetics and other fields, and has many physiological functions such as scavenging free radicals, whitening, anti-aging, maintaining DNA synthesis and normal cell growth.

L-Ergothioneine has unique biological characteristics:

1. Natural source: It naturally exists in fungi (such as edible fungi) and some animals and plants.

2. The human body can't synthesize ergothionine: the human body lacks the enzyme system to synthesize ergothionine, so it can't be produced by its own metabolism, and it must rely entirely on dietary intake.

3. Main sources: Boletus edulis, Pleurotus citrinopileatus, Lentinus edodes and other edible fungi are its main natural sources.

Based on its remarkable antioxidant activity, ergothionine is recognized as a natural and safe dietary nutrient.

How safe is L-ergothionine?

For a new food raw material, safety has always been the most concerned issue for the public. According to the Scientific Consensus, the safety of ergothionine has been fully confirmed:

1.No genotoxicity: many bacterial reversion mutation tests and mammalian erythrocyte micronucleus tests have not shown genotoxicity.

2.Good tolerance: The clinical study of the population shows that healthy volunteers take it continuously within the recommended dose range (5~25 mg per day), and no adverse events related to the test substance are found, and the liver and kidney functions and blood lipid indexes remain stable.

3.Large safety margin: Based on the existing evidence, the actual dietary intake is far lower than the "no adverse effect level" determined by animal experiments (NOAEL: 800 mg/kg bw).
