NutriBiotic Ascorbic Acid with Antioxidant Bioflavonoids Crystalline Powder Hypo-Allergenic pH 3.1 A Dietary Supplement NutriBiotic Ascorbic Acid with Bioflavonoid Complex delivers natural nutrients in concentrations higher than can be found in food, while being hypo-allergenic (free of all common food antigens). Our ascorbic acid is produced in a 15 step process, and has the highest solubility of all Pharmaceutical Grade vitamin C powders. It mixes easily in water or any other beverage. This potent, pure and 100% natural, water-soluble nutrient is then combined with phyto-antioxidant flavonoids from lemon. Vitamin C in whole foods is always found in combination with flavonoids. The action and stability of vitamin C, and other antioxidants, is enhanced by the presence of these natural plant antioxidants. This formulation replicates that natural synergism. Bioflavonoids are antioxidant co-factors always found with vitamin C in nature. The Bioflavonoid Complex in this product possesses the highest level of active compounds available. Bioflavonoids provide a wide range of physiological benefits. They are derived from the inner peel (albedo) of lemons. First, the peel is removed, dried, and powdered, yielding a product with 3% flavonoid activity. Then through added natural and rigorously controlled extraction and filtration methods, the flavonoid concentration is increased to the industry"s highest level: 50%. When you purchase any NutriBiotic product containing bioflavonoids, you will always be sure you are receiving a 50% extract. Slightly less acidic than ascorbic acid.
