Glutathione is the first line of protection against environmental chemical & toxins. Hence it protects against the mitochondrial DNA and nucleus of the cell. It is important in the protein biosynthesis process. It is transport amino acid into the cell where protein biosynthesis takes place.
However, glutathione can protect against stress of the immune system, allows newly formed immune cells to proliferate to attack germs and viruses. It also helps maintains oxidational levels of the cells.
Glutathione is also beneficial for its skin whitening effect. It works by interrupting melanin in our body. Melanin is the substance responsible for our skin colour, produced by the activation of the enzyme tyrosinase. Glutathione binds to tyrosinase, preventing the formation of melanin. Lesser melanin means a lighter skin tone.
Glutathione is the master antioxidant found in the liver; therefore helps in the liver detoxification process maintain skin radiance.
