A highly effective antioxidant and protects against both free radicals and the active forms of oxygen generated during normal metabolism. It has the ability to regenerate vitamin E. A recent study in smokers found that C regenerates vitamin E from its oxidized form.

It also stimulates the production and function of white blood cells, especially neutrophils, lymphocytes and phagocytes.

Vitamin C protects the integrity of the cells of the immune system. Neutrophils, mononuclear cells, phagocytes and lymphocytes accumulate Vitamin C in high concentrations and protect these cell types from oxidative damage. When there are "invaders", the phagocytes release peroxide radicals, hypochlorous acid, and other oxidants.

These active forms of oxygen kill the "invaders" but in the process simultaneously self-oxidize. Through its antioxidant capacity, it protects white blood cells from self-oxidation by boosting their glutathione levels.

Numerous randomized, double-blind, placebo-controlled studies have shown that Vitamin C improves vasodilation in people with cardiovascular problems.
