1. Antioxidant
Some oxidants occurs in body's metabolic process. The reductive mercapto group of L-Glutathione can reduce the oxidants to protect protein and enzyme from oxidation.
2. Detoxication
Heavy metal ions, like Hg2+, Ag2+, Pb2+ and As3+, connect irreversibly with the sulfhydryl of the enzyme in the body, inhibiting the enzyme activity. The mercapto group of L-Glutathione can connect with those heavy metal ions to protect mercapto enzymes.
3. Skin whitening
L-Glutathione can prevent the formation of new melanin and reduce its oxidation. It can bind with the copper ions of tyrosinase to cause inactivation of tyrosinase. And, it is able to reduce free radicals and peroxides to lower the activity of melanocytes. Also, it protects skin from UV radiation for its antioxidant property. Both internal and external use have good effect of skin whitening.
Dietary supplements, food, beverage
Whitening pill/capsule, whitening soap, whitening injection VSC
L-Glutathione is a very important antioxidant in human body, but it gradually decreases because of age, irregular life or diet, and so on. So it's necessary to supply it.
