What Is a Reasonable Vitamin E Dosage?

Even though the recommendations for vitamin E intake are confusing, dosing can be quite simple. Vitamin E comes in several strengths, but the most commonly made (and used) strengths are 400 IU and 1000 IU. No matter what form of vitamin E, 400 IU definitely exceeds the RDA. Since some studies have suggested that taking more than 400 IU of vitamin E a day may increase the risk of death (from all causes combined), it is usually recommended that vitamin E dosages not exceed 400 IU per day.
If you are concerned about meeting the recommended dietary requirements, a simple multivitamin will provide enough vitamin E (usually 30 IU). If you are interested in higher doses for other purposes, it is best to use 400 IU or less.

General Information on Dosing for Vitamin E

Considerations for people taking vitamin E include the following:
  • In general, you should not to take more than 400 IU of vitamin E daily without your healthcare provider's approval, since higher doses may potentially do more harm than good.
  • Although some sources suggest that vitamin E is best absorbed with a high-fat meal, research suggests that it probably does not matter much.
  • If you are unsure about anything related to your dosage or vitamin E dosing in general, please talk with your healthcare provider.
