In antioxidant cycling, antioxidants work together for an enhanced, combined effect. When the antioxidant vitamin E disables free radicals, it becomes a minor free radical. Both vitamin C and alpha-lipoic acid convert the radical form of vitamin E back to its antioxidant-self. However, when vitamin C recycles vitamin E, it changes to a free radical. Alpha-lipoic acid and glutathione can both “recycle” vitamin C back into a potent antioxidant.
Glutathione not only recycles vitamin C, but is the cells’ primary antioxidant. Maintaining high levels of glutathione is critical for life – low glutathione levels are a marker for death at an early age.
Glutathione diminishes as we age and cannot be boosted significantly through supplements. N-acetylcysteine manufactures glutathione, and alpha-lipoic acid regenerates glutathione, ensuring that the body has an adequate supply. Selenium is part of the enzyme glutathione peroxidase, which recycles glutathione.
OPCs also play a role in cycling as they sacrifice themselves in order to neutralize harmful free radicals. In doing so, they make it possible for vitamins C and E and selenium to do less “antioxidant” work, allowing these nutrients to perform their other functions in the body.
The ingredients found in AIM Proancynol® 2000 work together to provide optimum free radical protection.
