Vitamin E – The Antioxidant

Posted by Luca Willington

Vitamin E is a fat-soluble antioxidant crucially important for our skin’s health. Is also has a proven anti-inflmmatory effect, independent of its antioxidant action.

Vitamin E is a generic name for eight chemical compounds – four tocopherols (alpha-, beta-, gamma- and delta-) and four tocotrienols (alpha-, beta-, gamma- and delta-). Of these, the form most often found on cosmetic labels is alpha-tocopherol. It is also the most common form of Vitamin E naturally found in the human body.

Vitamin E’s Antioxidant Function

Antioxidants can inhibit the oxidative damage in our bodies neutralising free radicals or preventing their formation. Free radicals are unstable atoms or molecules – they need an electron to become stable, and they will “steal” it from the nearest available molecule. When the “attacked” molecule loses its electron, it can become a free radical itself. This can be the beginning of a free radical chain reaction. When out of control, free radical chain reactions cause cell damage or death.

The body has the ability to keep free radicals in check. To that end, it need antioxidants. Antioxidant molecules are able to donate an electron and yet remain stable, so they don’t become free radicals themselves. Since antioxidants are stable with or without the extra electron, they can act as free radical scavengers. Vitamin E is the primary defender against lipid peroxidation i.e. it prevents the oxidation of fats and oils in our bodies. (Research Info) Read the rest of this entry »
