Advanced Info 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 for 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. The body’s need for vitamin C increases during times of stress because vitamin C participates in the production of vital chemicals, such as those needed for the "fight or flight" response. Natural Factors Vitamin C 500 mg also contains 500 mg of citrus bioflavonoids, plus rutin, hesperidin, and rosehips. Bioflavonoids protect, strengthen, maintain and repair collagen, capillaries and connective tissue; and possess powerful anti-inflammatory and antioxidant agents. Bioflavonoids have been shown to improve the absorption and therapeutic action of vitamin C and protect vitamin C from oxidation in the body.
