A large new study suggests vitamin E may help prevent death from
cancer
and heart disease in middle-aged men who smoke, contradicting the
findings of some previous studies on the subject.
In a study of 29,092 Finnish men in their 50s and 60s who were
smokers,
those with the highest concentrations of the vitamin E in their
blood
at the study's outset were the least likely to die during the
follow-up
period, which lasted up to 19 years, Dr. Margaret E. Wright of the
National Cancer Institute in Bethesda, Maryland and colleagues
report.
There are a number of mechanisms by which vitamin E, also known as
alpha-tocopherol, might promote health, Wright and her team note in
the
current issue of the American Journal of Clinical Nutrition. For
example, vitamin E is a powerful antioxidant, while it also boosts
immune system function and prevents tumor blood vessel growth.
But studies investigating blood levels of vitamin E and mortality,
as
well as the effects of taking supplements of the vitamin, have had
conflicting results.
In the current study, Wright and her colleagues compared men's
levels
of alpha tocopherol at the beginning of the study, before they had
begun taking the supplements, with their mortality over the course
of
the study's follow-up period.
Men with the highest levels of vitamin E in their blood were 18
percent
less likely to die than those with the lowest levels, the
researchers
found. They also had a 21-percent lower risk of death from cancer,
a
19-percent lower risk of dying from heart disease, and a 30-percent
lower risk of death from other causes.
The optimum concentration appeared to be 13 to 14 milligrams
vitamin E
per liter of blood, with higher concentrations offering no
additional
benefit.
Because trials of vitamin E supplements have shown no effect on
mortality, the findings don't suggest that they would be
beneficial,
but do suggest that people can benefit from getting more vitamin E
in
their diet through foods such as "nuts, seeds, whole grains, and
dark-green leafy vegetables," the researchers conclude.

Thanks, Roman. Many studies not favorable to vitamin E have been
supplement intake studies, meaning that IU's of vitamin E (as
opposed
to serum levels), were measured. Such endpoint data may only
reflect
the quality of the supplement, ie., its ability to provide a
metabolized nutrient. It's not surprising that synthetic vitamin E,
which is known to be inferior in function to natural vitamin E, has
made up a large percentage of the vitamin E available to consumers
over
the years. In most any drug store, it is difficult to find the
completely natural form. A "dl" designation in the ingredient list
will indicate synthetic vitamin E, while "d" indicates natural.

AND mixed tocopherols are WAY better than simple d-alpha.
Agreed. The only supplement I know that includes them all is "Unique
E," by AE Grace, but there may be others.
PeterB
There are MANY.
That shows how behind I am on this. Is there a brand you like that I
might not know about?
Off the top I know of two that are quite different in constitution.
NOW products
