Vitamin C is a powerful vitamin with infection-fighting properties, playing a large role in immune system function. Vitamin C is crucial for the formation of collagen, making this vitamin very important for wound repair, healthy gums, strong bones and teeth, and in the prevention of bruising. As a powerful antioxidant, it protects the aqueous areas of the body (including the blood, intracellular fluid and interstitial fluid) from free radicals. Because it is a water-soluble vitamin, the body cannot store vitamin C, making regular supplementation vital. Natural Factors 100% C 500 mg natural fruit chews in blueberry, raspberry, and boysenberry flavours are made with natural fruit flavours and sweeteners. Each easy-to-take wafer also contains citrus bioflavonoids, rosehips, and rutin for added benefits. Bioflavonoids have been shown to improve the absorption and therapeutic action of vitamin C and protect vitamin C from oxidation in the body, allowing the body to reap more benefits from the vitamin. Also known to have a positive impact on the cardiovascular system as well as memory, bioflavonoids increase vitamin C absorption.
