NORTHRIDGE, Calif., Nov. 16 /PRNewswire/ -- Pharmavite, makers of Nature
Made(R) vitamins and supplements said the conclusions drawn by Johns Hopkins
researchers on vitamin E use and increased mortality risk are misleading
because the researchers only looked at a select, limited group of studies.
The researcher's conclusions appeared in the November 10 online edition of The
Annals of Internal Medicine.
"This analysis focused on a carefully selected group of earlier published
clinical studies whose populations suffered from a number of grave diseases
where there was a very high risk of mortality to begin with, including
Alzheimer's, Parkinson's, cancer, cardiovascular disease and more," said Dave
Madsen, Ph.D., Pharmavite director of scientific affairs. "The researchers
chose not to review long term studies of the general population which
demonstrate vitamin E's positive health benefits, including the Nurses Study,
the Finnish Study and the Iowa Women's Study." (1) (2) (3)
For example, a study of approximately 90,000 nurses suggested that the
incidence of heart disease was 30 to 40 percent lower among nurses with the
highest intake of vitamin E from diet and supplements. Researchers found that
the apparent benefit was mainly associated with intake of vitamin E from
dietary supplements. High vitamin E intake from food was not associated with
significant cardiac risk reduction.
Vitamin E is a fat-soluble vitamin and a powerful antioxidant that has
been touted for its numerous health benefits, including a study by Johns
Hopkins researchers published in the Annals of Neurology showing that 400 IUs
of vitamin E, taken in concert with 500 mg of vitamin C, reduced the risk of
Alzheimer's by 60 percent. (4)
"There is a great body of evidence documenting the proven health benefits
of Vitamin E. People who want to maintain good health should consume 100 to
400 IUs of vitamin E every day, in addition to maintaining a healthy diet,"
says Carroll Reider, M.S., R.D., Pharmavite director of consumer education.
Madsen reported other weaknesses in the analysis including the fact that
only nine of the studies reviewed had people taking vitamin E alone, and that
18 of the 19 studies analyzed had no statistically significant increase in
mortality. Further, the Institute of Medicine (IOM) has set the upper
tolerable intake level for vitamin E at 1,000 mg or 1,600 IUs per day.
Madsen said, "The IOM defines upper limit as 'the maximum intake of a
nutrient that is likely to pose no risk of adverse health effects in almost
all healthy individuals in the general population.' It will take more than
one skewed analysis of pre-existing studies to refute this long-standing
"The bottom line: Overwhelming evidence supports that vitamin E is safe
when taken as recommended and has proven health benefits for healthy people."
