Fact Sheet

Vitamin E

Vitamin E is a fat soluble vitamin that has anti-oxidant properties- it helps protect fatty cell membranes from becoming oxidized from free radicals. Vitamin E has been dubbed the 'vitamin in search of a deficiency disease'. Although deficiency symptoms are rare, recent research has shown that higher intake of vitamin E is associated with protection against diseases associated with ageing- ie cancer and heart disease. Vitamin E supplementation has been suggested as a stimulant for the immune system(1).

Vitamin E is also commonly used as a supplement to improve dry skin. Although there is no definite basis for its use in skin care, anecdotal reports do indicate it may be of benefit. Vitamin E is a constituent of many beauty creams that are applied to the face.

Vitamin E is measured as mg or international units (1 mg = 1.49 i.u).

Deficiency

Deficiency of vitamin E in the diet has no defined disease but chronic deficiency has been implicated as a contributor to cancer and heart disease.

Benefits

The recommended daily allowance of Vitamin E is 10mg per day but the upper safe level for daily supplementation = 800mg (1200i.u.). Together with Vitamins C and A they are known as the'anti-oxidant group'. The combination is also important for prevention of respiratory ailments and asthma.
