Oregon State Finds Vitamin E Intake Critical During “The First 1000 Days”

Amid conflicting reports about the need for vitamin E and how much is enough, a new analysis published today suggests that adequate levels of this essential micronutrient are especially critical for the very young, the elderly, and women who are or may become pregnant.

A lifelong proper intake of vitamin E is also important, researchers said, but often complicated by the fact that this nutrient is one of the most difficult to obtain through diet alone. Only a tiny fraction of Americans consume enough dietary vitamin E to meet the estimated average requirement.

Meanwhile, some critics have raised unnecessary alarms about excessive vitamin E intake while in fact the diet of most people is insufficient, said Dr. Maret Traber, a professor in the College of Public Health and Human Sciences at Oregon State University, principal investigator with the Linus Pauling Institute and national expert on vitamin E.

“Many people believe that vitamin E deficiency never happens,” Dr. Traber said. “That isn’t true. It happens with an alarming frequency both in the United States and around the world. But some of the results of inadequate intake are less obvious, such as its impact on the nervous system and brain development, or general resistance to infection.”

Some of the best dietary sources of vitamin E – nuts, seeds, spinach, wheat germ and sunflower oil – don’t generally make the highlight list of an average American diet. One study found that people who are highly motivated to eat a proper diet consume almost enough vitamin E, but broader surveys show that 90 percent of men and 96 percent of women don’t consume the amount currently recommended, 15 milligrams per day for adults.

In a review of multiple studies, published in Advances in Nutrition, Dr. Traber outlined some of the recent findings about vitamin E. Among the most important are the significance of vitamin E during fetal development and in the first years of life; the correlation between adequate intake and dementia later in life; and the difficulty of evaluating vitamin E adequacy through measurement of blood levels alone.

Findings include:

Dr. Traber said she recommends a supplement for all people with at least the estimated average requirement of vitamin E, but that it is particularly important for all children through about age two; for women who are pregnant, nursing, or may become pregnant; and for the elderly.

This research was supported in part by the National Institutes of Health.
