The RDA recommends the average daily dietary intake level that is sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in each age and gender group .

In Table 2, RDAs for vitamin E are based only on the alpha-tocopherol form of vitamin E . Table 2 also lists RDAs for vitamin E in International Units (IU) because food and most supplement labels list vitamin E content in International Units (1 mg alpha-tocopherol vitamin E = 1.49 IU).

There is insufficient scientific data on vitamin E to establish an RDA for infants. An Adequate Intake (AI) has been established that is based on the amount of vitamin E consumed by healthy infants who are fed breast milk. Table 2 lists the adequate intakes for vitamin E for infants in mg alpha-tocopherol and IUs (1 mg alpha-tocopherol = 1.49 IU) .

"Low-fat diets can substantially decrease vitamin E intakes if food choices are not carefully made to enhance α-tocopherol intakes" [

Who is at risk for vitamin E deficiency?

Vitamin E deficiency is rare in humans. There are three specific situations when a vitamin E deficiency is likely to occur.
  1. persons who cannot absorb dietary fat due to an inability to secrete bile or with rare disorders of fat metabolism are at risk of vitamin E deficiency;
  2. individuals with rare genetic abnormalities in the alpha-tocopherol transfer protein are at risk of vitamin E deficiency ; and
  3. premature, very low birth weight infants (birth weights less than 1500 grams, or 3 pounds, 4 ounces) are at risk of vitamin E deficiency
Blood levels of vitamin E may also be decreased with zinc deficiency Vitamin E deficiency is usually characterized by neurological problems associated with nerve degeneration in hands and feet . These symptoms are also associated with other medical conditions. A physician can determine if they are the result of a vitamin E deficiency or are from another cause.
