Introduction
S-acetyl-L-glutathione is an acetylated modified reduced L-glutathione with much better stability and cell membrane penetration compared to ordinary L- glutathione. It is resistant to degradation by gastric acid and significantly enhances oral bioavailability. S-A-GSH is a novel compound widely used in the nutraceutical and pharmaceutical industries, particularly for anti-aging, liver detoxification, skin whitening, and dietary supplements and skin care products. It is the upgraded form of L- glutathione
