谷胱甘肽Glutathione (GSH)

Glutathione (GSH) is a powerful tripeptide composed of glutamine, cysteine, and glycine, naturally produced in the body. It plays a critical role in cellular defense against oxidative stress by neutralizing free radicals and maintaining the redox balance within cells. GSH also supports liver detoxification, immune function, and the regeneration of other antioxidants such as vitamins C and E.

As a "master antioxidant," glutathione is especially valued for its anti-aging, skin-brightening, and immune-boosting properties. Supplementation is popular among individuals seeking to improve skin tone, reduce inflammation, and enhance overall wellness. However, the body’s GSH levels decline with age, stress, illness, or exposure to toxins, making dietary intake or supplementation beneficial.

In nutraceuticals and cosmetics, reduced glutathione (GSH) is widely used due to its high bioactivity. Available in oral, sublingual, and intravenous forms, GSH continues to attract interest across global health and beauty markets.
