Ultra A-O is a potent antioxidant supplement that includes vitamins and other nutrients that effectively participate in our body's antioxidant defence systems. This is beneficial as the uncontrolled production of free radicals is thought to be a major contributing factor to many degenerative pathologies.
Vitamin E is recognized as the body's most valuable fat soluble antioxidant. It prevents the oxidation of unsaturated fatty acids by inactivating free radicals, thus stabilizing and protecting cell membranes.
Vitamin C is a potent water-soluble antioxidant nutrient that is also essential for bone metabolism and immune function. When neutralizing free radicals inactivates vitamin E, vitamin C regenerates it back to full activity.
Glutathione is a naturally occurring tripeptide and a major component of two anti-free radical enzymes _ glutathione peroxidase and glutathione reductase. As such, glutathione scavenges toxic free radicals and inhibits peroxidation thereby slowing down free-radical catalyzed chain reactions. Glutathione can also reactivate (reduce) oxidized vitamin C and is dependent on selenium and B vitamins for its effectiveness. Similarly, zinc maintains the activity of the antioxidant enzyme superoxide dismutase.
N-acety-L-Cysteine is a precursor for the sulfur amino acid cysteine, which is used by cells to synthesize glutathione. Supplementation with N-acety-L-Cysteine is recognized as a safe and highly effective method of increasing intracellular glutathione stores.
