Vitamin E - Antioxidant action

Vitamin E is also known as tocopherol and it represents a series of compounds and derivatives that are antioxidants. Like the vitamin A, D and K, vitamin E is fat-soluble.

Alpha tocopherol is the main form found in the body and it acts as an antioxidant.

Why are antioxidants so important?
When we talk about antioxidant action, we have to immediately associate to the inactivation of free radicals.


Free radicals are formed in the body during normal metabolism and also upon exposure to environmental factors such as cigarette smoke, stress and pollutants.

Fats, which are part of all cell membranes, are vulnerable to destruction through oxidation by free radicals. Antioxidants react with free radicals and prevent a chain reaction of lipid (fat)destruction. Vitamin E is one of the antioxidants in the body that neutralizes free radicals.

When vitamin E neutralizes a free-radical molecule, it turns into an oxidized form that no longer can act as an antioxidant. Vitamin C is known to turn vitamin E back to its active form, capable to act as an antioxidant.

Sources and RDA
Natural sources of vitamin E include vegetable oils, nuts, whole grains, and green leafy vegetables. The current Recommended Dietary Allowance (RDA) for adults is 15mg per day.

The association of vitamins and other elements in our diet will maximize benefits and prevent diseases. Ultimately, beauty is health.

Be good, be healthy!
