Vitamin E is found in nuts, olive oil, and sunflower oil. The body uses vitamin E as an antioxidant to help fight damage to cells. Vitamin E can be taken as a pill and has been used to promote heart health. It has also been used to improve muscle and brain function.
Vitamin E can also be applied to the skin as an oil. It has been used to protect the skin from aging and damage from chemotherapy.
400 milligrams 1 to 2 times daily
Editorial process and description of evidence categories can be found at EBSCO NAT Editorial Process.
It is likely safe to use vitamin E on the skin and to take it orally in small doses for a short time. Doses higher than 1000 milligrams per day may not be safe. Not enough studies have been done to say whether it is safe to use for a long period. Women who are pregnant or breastfeeding should avoid high doses of vitamin E.
Talk to your doctor about any supplements or therapy you would like to use. Some can interfere with treatment or make conditions worse.
