Uses for Formula E 400
Vitamins are substances that your body needs for growth and health. You only need them in small amounts, and they come from the foods you eat. Vitamin E helps prevent a process called oxidation, which can sometimes harm your body. It is also important for how your nerves and muscles work.
Certain health conditions may increase your need for vitamin E. These include:
- Intestine disease
- Liver disease
- Pancreas disease
- Surgical removal of stomach
Your health care professional should determine if you need more vitamin E.
Infants who are on formula that does not have added vitamin E may be at risk for a vitamin E deficiency. Additionally, diets that are high in polyunsaturated fatty acids may raise your need for vitamin E.
There is no proof that vitamin E effectively treats cancer or prevents or treats acne, aging, hair loss, bee stings, liver spots on the hands, bursitis, diaper rash, frostbite, stomach ulcers, heart attacks, labor pains, certain blood diseases, miscarriage, muscular dystrophy, poor posture, sexual impotence, sterility, infertility, menopause, sunburn, or lung damage from air pollution. Although some people use vitamin E to try to prevent certain types of cancer, there isn't enough information to show that it works.
A lack of vitamin E is very rare, except in people who have conditions that prevent it from being absorbed by the body.
You can get vitamin E without a prescription.
To stay healthy, make sure you eat a balanced and varied diet. Follow any diet recommendations from your health care professional closely. If you think you are not getting enough vitamins and/or minerals from your diet, you might consider taking a dietary supplement.
You can find vitamin E in various foods, including vegetable oils (corn, cottonseed, soybean, safflower), wheat germ, whole-grain cereals, and green leafy vegetables. Cooking and storing these foods can reduce the amount of vitamin E they contain.
Vitamin supplements cannot replace a healthy diet and will not give you energy. Your body also needs other nutrients found in food, like protein, minerals, carbohydrates, and fat. Vitamins often need the presence of other foods to work properly. For example, you need small amounts of fat to absorb vitamin E.
The daily amount of vitamin E needed is defined in several ways.
- For U.S.—
- Recommended Dietary Allowances (RDAs) are the amounts of vitamins and minerals needed for adequate nutrition in most healthy people. RDAs may vary based on a person's age, sex, and health status (e.g., pregnancy).
- Daily Values (DVs) are used on food and dietary supplement labels to show the percentage of the recommended daily amount of each nutrient that a serving provides. DV replaces the earlier term United States Recommended Daily Allowances (USRDAs).
- For Canada—
- Recommended Nutrient Intakes (RNIs) are used to determine the amounts of vitamins, minerals, and protein needed for adequate nutrition and to reduce the risk of chronic disease.
Vitamin E comes in different 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 was expressed in Units. This has now been changed to alpha tocopherol equivalents (alpha-TE) or milligrams (mg) of d-alpha tocopherol. One Unit equals 1 mg of dl-alpha tocopherol acetate or 0.6 mg of d-alpha tocopherol. Most products sold in stores still use Units on their labels.
Normal daily recommended amounts in milligrams (mg) of alpha tocopherol equivalents (mg alpha-TE) and Units for vitamin E are generally defined as follows:
| Persons | U.S. | Canada | ||
|---|---|---|---|---|
| mg alpha-TE | Units | mg alpha-TE | Units | |
| Infants and children Birth to 3 years of age | 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 adult males | 10 | 16.7 | 6–10 | 10–16.7 |
| Adolescent and adult females | 8 | 13 | 5–7 | 8.3–11.7 |
| Pregnant females | 10 | 16.7 | 8–9 | 13–15 |
| Breast-feeding females | 11–12 | 18–20 | 9–10 | 15–16.7 |
