Glutathione binds free radicals that are formed in the body on a daily basis, inactivates them and stops cellular stress. It stimulates energy synthesis in mitochondria and prevents photoageing. It ensures a clean complexion and restores energy to the skin. L-cysteine enhances glutathione absorption and raises plasma concentrations. As an integral part of L-glutathione, it is also a reserve for this protein, which is why it is important that it is present in the body in sufficient quantities. It is needed for the formation of compounds and the formation of other amino acids. Vitamin C acts synergistically with glutathione and enhances the antioxidant effect. It acts as an exogenous antioxidant and reduces oxidative stress in the cell. It contributes to collagen synthesis and improves skin appearance.
