Vitamins are compounds that you must have for growth and health. They are needed in only small amounts and are available in the foods that you eat. Vitamin E prevents a chemical reaction called oxidation, which can sometimes result in harmful effects in your body. It is also important for the proper function of nerves and muscles.
Some conditions may increase your need for vitamin E. These include:
Increased need for vitamin E should be determined by your health care professional.
Infants who are receiving a formula that is not fortified with vitamin E may be likely to have a vitamin E deficiency. Also, diets high in polyunsaturated fatty acids may increase your need for vitamin E.
Claims that vitamin E is effective for treatment of cancer and for prevention or treatment of acne, aging, loss of hair, bee stings, liver spots on the hands, bursitis, diaper rash, frostbite, stomach ulcer, heart attacks, labor pains, certain blood diseases, miscarriage, muscular dystrophy, poor posture, sexual impotence, sterility, infertility, menopause, sunburn, and lung damage from air pollution have not been proven. Although vitamin E is being used to prevent certain types of cancer, there is not enough information to show that this is effective.
Lack of vitamin E is extremely rare, except in people who have a disease in which it is not absorbed into the body.
Vitamin E is available without a prescription.
For good health, it is important that you eat a balanced and varied diet. Follow carefully any diet program your health care professional may recommend. For your specific dietary vitamin and/or mineral needs, ask your health care professional for a list of appropriate foods. If you think that you are not getting enough vitamins and/or minerals in your diet, you may choose to take a dietary supplement.
Vitamin E is found in various foods including vegetable oils (corn, cottonseed, soybean, safflower), wheat germ, whole-grain cereals, and green leafy vegetables. Cooking and storage may destroy some of the vitamin E in foods.
Vitamin supplements alone will not take the place of a good diet and will not provide energy. Your body also needs other substances found in food such as protein, minerals, carbohydrates, and fat. Vitamins themselves often cannot work without the presence of other foods. For example, small amounts of fat are needed so that vitamin E can be absorbed into the body.
The daily amount of vitamin E needed is defined in several different ways.
Vitamin E is available in various forms, including d- or dl-alpha tocopheryl acetate, d- or dl-alpha tocopherol, and d- or dl-alpha tocopheryl acid succinate. In the past, the RDA for vitamin E have been expressed in Units. This term has been replaced by alpha tocopherol equivalents (alpha-TE) or milligrams (mg) of d-alpha tocopherol. One Unit is equivalent to 1 mg of dl-alpha tocopherol acetate or 0.6 mg d-alpha tocopherol. Most products available in stores continue to be labeled in Units.
Normal daily recommended intakes in milligrams (mg) of alpha tocopherol equivalents (mg alpha-TE) and Units for vitamin E are generally defined as follows:
|Infants and childrenBirth to 3 years ofage||3–6||5–10||3–4||5–6.7|
|4 to 6 years of age||7||11.7||5||8.3|
|7 to 10 years of age||7||11.7||6–8||10–13|
|Adolescent and adultmales||10||16.7||6–10||10–16.7|
|Adolescent and adultfemales||8||13||5–7||8.3–11.7|

Problems in children have not been reported with intake of normal daily recommended amounts. You should check with your health care professional if you are giving your baby an unfortified formula.

Your health care professional may recommend a vitamin E supplement.
Problems in older adults have not been reported with intake of normal daily recommended amounts.
