As a powerful antioxidant it protects the aqueous areas of the body (including the blood, intracellular fluid and interstitial fluid) from free radicals. Vitamin C protects LDL cholesterol from oxidation and also helps to regenerate vitamin E. As it is a water-soluble vitamin, the body does not store vitamin C, so regular supplementation is 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 norepinephrine, needed for the "fight or flight" response. Vitamin C also acts as a detoxifier, helping to cleanse the body of toxins, such as cigarette smoke, carbon monoxide, etc. Natural Factors includes bioflavonoids in their vitamin C products.
