Vitamin E
Overview
Vitamin E is a vitamin that dissolves in fat. It is found in many foods including vegetable oils, cereals, meat, poultry, eggs, fruits, vegetables, and wheat germ oil. It is also available as a supplement.
Vitamin E is used for treating vitamin E deficiency, which is rare, but can occur in people with certain genetic disorders and in very low-weight premature infants. Vitamin E is also used for many other conditions, but there is no good scientific evidence to support these other uses.
The American Heart Association recommends obtaining antioxidants, including vitamin E, by eating a well-balanced diet high in fruits, vegetables, and whole grains rather than from supplements until more is known about the risks and benefits of taking supplements.
A type of vitamin E called vitamin E acetate is an ingredient in some vaping products. Using vaping products containing vitamin E acetate has been linked to serious lung injury.
Classification

Vitamin
Primary Functions:
Vitamin E deficiency
Also Known As:
Acétate d'Alpha Tocophérol, Acétate d'Alpha Tocophéryl
How Does It Work?
Vitamin E is an important vitamin required for the proper function of many organs in the body. It is also an antioxidant. This means it helps to slow down processes that damage cells.
Uses
- An inherited condition that affects motor control (ataxia with vitamin E deficiency or AVED). The genetic movement disorder called ataxia causes severe vitamin E deficiency. Vitamin E supplements are used as part of the treatment for ataxia.
- Vitamin E deficiency. Taking vitamin E by mouth is effective for preventing and treating vitamin E deficiency.
- Alzheimer disease. Some early research suggests that dietary intake of vitamin E is linked to a lower chance of developing Alzheimer disease. But not all research agrees. Taking vitamin E supplements doesn't seem to prevent Alzheimer disease from developing. In people who already have Alzheimer disease, taking vitamin E along with some anti-Alzheimer medicines might slow down the worsening of memory loss. Vitamin E might also delay the loss of independence and the need for caregiver assistance in people with mild-to-moderate Alzheimer disease.
- Low levels of red blood cells in people with long-term illness (anemia of chronic disease). Some research shows that that taking vitamin E improves the response to the drug erythropoietin, which affects red blood cell production, in adults and children on hemodialysis.
- A blood disorder that reduces levels of protein in the blood called hemoglobin (beta-thalassemia). Taking vitamin E by mouth seems to benefit children with the blood disorder called beta-thalassemia and vitamin E deficiency.
- Leakage of intravenous (IV) drug from the vein into the surrounding skin and tissue (extravasation). Applying vitamin E to the skin together with dimethylsulfoxide (DMSO) seems to be effective for treating leakage of chemotherapy into surrounding tissues.
- Menstrual cramps (dysmenorrhea). Taking vitamin E for 2 days before bleeding and for 3 days after bleeding starts seems to decrease pain and reduce menstrual blood loss. Taking vitamin E with fish oil might provide even more pain relief than taking vitamin E alone.
- Scarring or hardening of blood vessels in the kidney (glomerulosclerosis). There is some evidence that taking vitamin E by mouth might improve kidney function in children with glomerulosclerosis.
- An inherited disorder that causes red blood cells to break down in response to stress (G6PD deficiency). Some research shows that taking vitamin E by mouth, alone or together with selenium, might benefit people with an inherited disorder called G6PD deficiency.
- A type of non-cancerous skin sore (granuloma annulare). Applying vitamin E to the skin seems to clear up skin sores called granuloma annulare.
- An inherited brain disorder that affects movements, emotions, and thinking (Huntington disease). Natural vitamin E (RRR-alpha-tocopherol) can improve symptoms in people with early Huntington disease. However, it doesn't seem to help people with more advanced disease.
- Bleeding within the skull (intracranial hemorrhage). Taking vitamin E by mouth seems to be effective for treating bleeding in the skull in premature infants.
- Bleeding into or around the fluid-filled areas (ventricles) of the brain (intraventricular hemorrhage). Some research shows that giving vitamin E by mouth to premature infants can reduce the risk for bleeding into the brain. But giving high doses of vitamin E might increase the risk for a serious blood infection (sepsis) in these infants.
- Conditions in a man that prevent him from getting a woman pregnant within a year of trying to conceive (male infertility). Taking vitamin E by mouth improves pregnancy rates for men with fertility problems. But taking high doses of vitamin E together with vitamin C doesn't seem to provide the same benefits.
- Reduced benefit of nitrate therapy that happens when nitrates are used all day (nitrate tolerance). There is some evidence that taking vitamin E daily can help prevent nitrate tolerance.
- Swelling (inflammation) and build up of fat in the liver in people who drink little or no alcohol (nonalcoholic steatohepatitis or NASH). Taking vitamin E daily seems to improve inflammation and liver markers of this form of liver disease in adults and children.
- Parkinson disease. People who get more vitamin E in their diet might have a lower risk of Parkinson disease. Taking supplements containing vitamin E doesn't seem to benefit people already diagnosed with Parkinson disease.
- Recovery from laser eye surgery (photoreactive keratectomy). Taking high doses of vitamin A along with vitamin E (alpha-tocopheryl nicotinate) daily seems to improve healing and vision in people undergoing laser eye surgery.
- Premenstrual syndrome (PMS). Taking vitamin E by mouth seems to reduce anxiety, craving, and depression in some women with PMS.
- Physical performance in elderly adults. Research suggests that increasing vitamin E intake in the diet is linked with improved physical performance and muscle strength in older people.
- Scarring of tissue caused by radiation therapy. Taking vitamin E by mouth with the drug pentoxifylline seems to treat scarring caused by radiation. However, taking vitamin E alone doesn't seem to be effective.
- Rheumatoid arthritis (RA). Vitamin E taken along with standard treatment is better than standard treatment alone for reducing pain in people with RA. However, this combination doesn't reduce swelling.
- Sunburn. Taking high doses of vitamin E (RRR-alpha-tocopherol) by mouth together with vitamin C protects against skin inflammation after exposure to UV radiation. However, vitamin E alone doesn't provide the same benefit. Applying vitamin E to the skin, together with vitamin C and melatonin, provides some protection when used before UV exposure.
- A movement disorder often caused by antipsychotic drugs (tardive dyskinesia). Taking vitamin E by mouth seems to improve symptoms associated with the movement disorder called tardive dyskinesia. However, some other research suggests that it doesn't improve symptoms, but may prevent symptoms from worsening.
- Swelling (inflammation) of the eye (uveitis). Taking vitamin E with vitamin C by mouth seems to improve vision, but doesn't reduce swelling, in people with uveitis.

- For preventing sunburn: Vitamin E in combination with topical vitamin C and melatonin applied to the skin prior to sun exposure.
CHILDREN
BY MOUTH:
- For an inherited condition that affects motor control (ataxia with vitamin E deficiency or AVED): 40 mg/kg of RRR-alpha-tocopherol or all-rac-alpha-tocopherol daily.
- For a blood disorder that reduces levels of protein in the blood called hemoglobin (beta-thalassemia): 298 mg of vitamin E daily for 4-8 weeks.

- For swelling (inflammation) and build up of fat in the liver in people who drink little or no alcohol (non-alcoholic steatohepatitis or NASH): 400-1200 IU of vitamin E daily.
For the most benefit, it's best to take vitamin E that has been made in a lab (all-rac-alpha-tocopherol) with food.
Dosing for vitamin E can be confusing. Current guidelines show recommended dietary allowance (RDA) and tolerable upper intake limits (UL) for vitamin E in milligrams. However, most products are still labeled in International Units (IUs).
