Vitamin E Good or Bad
for Those with Diabetes?
posted December 01, 2004
Last week a study came out that said
it was bad, this week we have a study that says it’s good?
A new study, published in the November issue of the journal "Diabetes Care" has
indicated that about 40 percent of diabetic patients can reduce their risk of
heart attacks and of dying from heart disease by taking vitamin E supplements.
According to the study, conducted by researchers at the Technion- Israel
Institute of Technology, diabetics with a particular form of a blood protein
called haptoglobin has as much as a 500 percent increased risk of developing
heart disease.
But when these at-risk patients, who have the 2-2 form of haptoglobin, take 400
international units of vitamin E daily, they reduce their risk of heart attack
by 43 percent, and their risk of dying of heart disease by 55 percent.
About 40 percent of diabetics have the 2-2 form of haptoglobin, while the rest
have the 1 -1 or 2-1 forms. When they took the same vitamin E supplements, they
did not show any significant reduction of cardiovascular risk resulting from
vitamin E therapy.
The researchers had earlier demonstrated that haptoglobin 2-2 is predictive of
heart disease, but only in people with diabetes. That's because diabetics tend
to have more free radicals that destroy antioxidants. Furthermore, haptoglobin
2-2 is a very poor antioxidant when compared to the other haptoglobin types.
This combination means that diabetics with haptoglobin 2-2 have an even greater
deficiency of antioxidants than do diabetics with the other haptoglobin
variants. Therefore, an increased supply of antioxidants, such as those found in
vitamin E, would be expected to provide the greatest benefit for these patients.
"If this larger study confirms our findings, the public health implications will
be huge. Vitamin E would represent an inexpensive and safe way to reduce the
risk of cardiovascular death and heart attack in a significant proportion of
diabetic patients," the researchers wrote in their study.
