People
should use caution in interpreting the HOPE-TOO study.
- Its unprecedented findings reflect a study population
of older patients (average age over 70 at the end of
the study).
- Subjects already had vascular heart disease or very
strong risk factors.
- The study patients also were taking a variety of medications
for different health conditions.
- "Heart failure" as used in the report is
not a heart attack, stroke or death, but a decreased
volume of blood being pumped.
It is not the final wordeven
older patients with a history of heart disease, stroke
or diabetes should understand the study results should
be viewed in the context of other research.
- The study authors concede the results are "unexpected,"
have not been found in any other clinical trial, and
"could be due to chance."
- This study is not the final word on vitamin Eother
clinical trials are already underway.
Vitamin E provides significant health
benefits.
- This study must not obscure vitamin Es essential
role in life and health, nor its long-term benefits.
- The recently revised federal Dietary Guidelines confirm
that most Americans dont get enough vitamin
E in their diets (http://www.ods.od.nih.gov/factsheets/vitamine.asp).
Supplements can fill that gap.
- Vitamin E has many potential long-term benefits for
healthy people, including protecting against oxidative
damage in body cells and reducing harmful inflammation.
- There is study evidence that vitamin E helps protect
against:
- Infectious diseases, especially upper respiratory
infections
- Some cancers
- Eye diseases
- Neurological diseases such as Alzheimers
- Cardiovascular disease in some populations
Vitamin E supplements in common
dosages are safe.
The Institute of Medicine (IOM), a scientific advisory
body, states that vitamin E supplements are safe within
a wide range up to 1,000 mg (1,000 IU synthetic or 1,500
IU natural). HOPE-TOO subjects were taking 400 IU, much
less than the upper level IOM considers to be without
harm. Leading researchers also continue to believe supplements
are safe at high levels, and several on-going studies
are using doses above 400 IU.
Ongoing clinical trials involving
tens of thousands of subjects reflect researchers
confidence in the safety and likely benefit of vitamin
E.
