Glutathione (GSH) is a peptide synthesized in cells from glutamic acid, cysteine and glycine. It is one of the most important non-protein sulfhydryl compounds in organisms. It is very abundant in eukaryotes Small molecule thiols, which play a key role in oxidative metabolism. Among them, reduced glutathione is the active form, which accounts for the most under physiological conditions, about 95%, and has a high free radical scavenging rate; oxidized glutathione can assist reduced glutathione Free radical scavenging. This synergy is related to the ratio of GSH and GSSG. When the ratio of GSH and GSSG is 100:1, the free radical scavenging rate is the highest.

When ultraviolet rays irradiate the skin, a large number of free radicals will be generated, which will activate the production mechanism of melanin. Glutathione can destroy these free radicals and prevent melanin production from the front. Glutathione can inhibit the activity of tyrosinase and regulate the conversion mechanism from eumelanin to pheomelanin production. Glutathione is widely involved in all aspects of melanin production, which can scavenge free radicals, resist oxidation, whiten skin, lighten spots, and have anti-aging effects.


GSH can assist other "exogenous" antioxidants without self-circulation function, such as VA, VC, VE, etc., to circulate in the body. GSH works well in combination with major antioxidants such as coenzyme Q10, lipoic acid, and selenium. Through these, it will help to delay aging and keep the skin clear and bright.


Supplementing a certain concentration of GSH can increase the content of GSH in the cells, which can effectively improve the body's functions, self-repair, disease resistance and anti-aging through various channels.


At present, GSH is mainly used in the production of pharmaceuticals, medical beauty and health care products, and can also be used as a food additive, plant health and beauty care products.
