ActiVite contains L-Glutathione with L-Cysteine, Alpha-Lipoic Acid and Niacinamide. Glutathione is a natural substance found in the human body. It is composed of 3 types of amino acids; glutamate, cysteine and glycine. Benefits of Glutathione: 1. Inhibits melanin synthesis resulting in a brighter and whiter appeal. 2. Provides antioxidant property preventing cell deterioration. 3. Lack of glutathione will lead to oxidative stress. Glutathione makes your skin clear and bright by interfering with the metabolic pathway of melanin synthesis leading to reduction of large black melanins. Cysteine, a glutathione generation amino acid enhancer, has potent antioxidant activity. Alpha-lipoic acid, another powerful antioxidant, can effectively reduce oxidative stress as well as restore glutathione. Glutamine is the source of glutamate which is a precursor in building glutathione in our body. A study from Australia revealed that with higher blood glutamine, glutathione synthesis is accelerated. Moreover, both cysteine and glycine play an important role in facilitating glutathione production. Alpha-Lipoic Acid is an effective antioxidant vital to the reduction of oxidative stress. In addition, it promotes re-synthesis of used-up glutathione back to the active state. Vitamin B3 (niacin) is essential for maintaining healthy skin, hair, eyes and the nervous system. Lack of niacin will lead to a condition called pellagra. The skin will appear rough, easily bruised and hyper-pigmented. In summary, the above mentioned nutrients are all vital for naturally beautiful skin. Together with the consumption of nutritious food, adequate rest, regular exercise and avoidance of external hazardous stimuli (pollution, ultraviolet light and smoke), you will easily have a youthful, healthy and beautiful skin.
