AlphaGuard Plus is one of the very best all-in-one antioxidant supplements on the market today, combining many of the most effective antioxidant nutrients and complexes, including Vitamin C, Grape Seed Extract, Curcumin Extract, Quercetin, Zinc, Bilberry Extract, Vitamin E, Alpha lipoic acid, Green tea extract, N-Acetyl cysteine, Zinc, Leutein, Beta-carotene, Lycopene, Zeaxanthin and Selenium. The reason we put such a potent variety of antioxidants into our supplement is that antioxidants work synergistically in the body — their combined benefit far exceeding the benefit we would obtain from taking them separately. And not only that, many of them have their own unique and essential function, so they must all be present for optimum well-being. This makes AlphaGuard Plus the ideal food supplement for helping to prevent excessive oxidation in the body.
