The vitamin C and vitamin E, are known to protect the body against the destructive effects of free radicals. Antioxidants neutralize free radicals by donating one of their own electrons, ending the electron-"stealing" reaction. The antioxidant nutrients themselves don't become free radicals by donating an electron because they are stable in either form. They act as scavengers, helping to prevent cell and tissue damage that could lead to cellular damage and disease.
Vitamin E is the most abundant fat-soluble antioxidant in the body. Vitamin E is one of the most efficient chain-breaking antioxidants available. It is the primary defender against oxidation and lipid peroxidation (creation of unstable molecules containing more oxygen than is usual).
Vitamin C is the most abundant water-soluble antioxidant in the body. Vitamin C acts primarily in cellular fluid. It is particularly beneficial in combating free-radical formation caused by pollution and cigarette smoke. It also helps return vitamin E to its active form.
