Xi an Pincredit Bio-tech Co., Ltd sell "L-Ergothioneine Powder"

Main specifications: mushroom-extracted grades at 0.5% and 1%, and a fermented grade at 99%. L-ergothioneine powder is sourced either from natural mushroom extraction (Agaricus blazei), yielding a brown powder at 0.5% and 0.1% purity, or from fermentation, yielding a white crystalline powder at 99% purity. The powder is generally water-soluble but insoluble in organic solvents. It functions as a natural antioxidant that protects cells in the body and serves as an important active substance; research shows cells deficient in ergothioneine are more vulnerable to oxidative stress, leading to greater mitochondrial DNA damage, protein oxidation, and lipid peroxidation.
