NutriBiotic Ascorbic Acid with Antioxidant Bioflavonoids delivers 100% pharmaceutical grade vitamin C, an essential nutrient beneficial to the body's overall health, and antioxidant bioflavonoids from lemon in a highly soluble form. Since vitamin C is not produced by the body, it must be replenished daily. Vitamin C is often found in nature accompanied by bioflavonoids, a group of water-soluble plant pigments. Bioflavonoids work synergistically with vitamin C in the body to play an important role supporting numerous biochemical reactions, such as normal fluid balance, the function of various enzyme systems, tissue growth and repair, and strengthening the walls of blood vessels. NutriBiotic Ascorbic Acid with Antioxidant Bioflavonoids is well tolerated by most highly allergic individuals.
