The Importance of Vitamin E Intake During ‘The First 100 Days’ of Pregnancy

A new study has revealed that vitamin E is especially critical for the very young, the elderly, and women who are or may become pregnant.

According to researchers, 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 and it has been estimated that only a tiny fraction of Americans consume enough dietary vitamin E to meet the estimated average requirement.

The study found that inadequate vitamin E is associated with increased infection, anemia, stunting of growth and poor outcomes during pregnancy for both the infant and mother and overt deficiency, especially in children, can cause neurological disorders, muscle deterioration, and even cardiomyopathy.

Meanwhile, some critics have raised unnecessary alarms about excessive vitamin E intake while in fact the diet of most people is insufficient, said 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.

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:

  • Inadequate vitamin E is associated with increased infection, anemia, stunting of growth and poor outcomes during pregnancy for both the infant and mother.
  • Overt deficiency, especially in children, can cause neurological disorders, muscle deterioration, and even cardiomyopathy.
  • Studies with experimental animals indicate that vitamin E is critically important to the early development of the nervous system in embryos, in part because it protects the function of omega-3 fatty acids, especially DHA, which is important for brain health. The most sensitive organs include the head, eye and brain.
  • One study showed that higher vitamin E concentrations at birth were associated with improved cognitive function in two-year-old children.
  • Findings about diseases that are increasing in the developed world, such as non-alcoholic fatty liver disease and diabetes, suggest that obesity does not necessarily reflect adequate micronutrient intake.
  • Measures of circulating vitamin E levels in the blood often rise with age as lipid levels also increase, but do not prove an adequate delivery of vitamin E to tissues and organs.
  • Vitamin E supplements do not seem to prevent Alzheimer’s disease occurrence, but have shown benefit in slowing its progression. A report in elderly humans showed that a lifelong dietary pattern that resulted in higher levels of vitamins B,C, D and E were associated with a larger brain size and higher cognitive function.
  • Vitamin E protects critical fatty acids such as DHA throughout life, and one study showed that people in the top quartile of DHA concentrations had a 47 percent reduction in the risk of developing all-cause dementia.

“It’s important all of your life, but the most compelling evidence about vitamin E is about a 1000-day window that begins at conception,” Traber said. “Vitamin E is critical to neurologic and brain development that can only happen during that period. It’s not something you can make up for later.”

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