In the past few years we've been bombarded by sensational news reports about the possible danger of taking higher doses of Vitamin E. These reports have been based on a review article that was published in the Annuals of Internal Medicine [4 January 2005; Vol. 142 No. 1] written by Dr. Edgar Miller, of the John Hopkins School of Medicine. Miller concluded that a "high" dosage of vitamin E supplements (over 400 IU per day) may increase death rates and should be avoided. Obviously, careful evaluation of this study is warranted, since most of us are consuming these optimal or advanced levels of vitamin E.
The Rest of the Wonderful Story
Here are important facts that the media reports didn't mention:
• This is not a new study. It is simply a review of 36 controlled trials, with follow-up of longer than 1 year, done from 1966 to 2004. There is no new research here, just an interpretation of old data.
• Only 19 trials were considered for statistical interpretation. Out of the original 36, they eliminated 17 trials that did not have more than ten deaths.
• None of the individual trials noted any statistically significant differences in the mortality between the control group and the Vitamin E group.
• The studies involved patients that were already very ill. For example, the CHAOS study (Cambridge Heart Antioxidant Study) involved over 2,000 patients who had already suffered a heart attack. The ADCS study (the Alzheimer's Disease Cooperative Study) involved patients who already had moderate to severe Alzheimer's dementia.
• Many of the patients in both the Vitamin E group and the control group died.
• 8 of the 19 studies actually showed fewer deaths in the Vitamin E group than the control group. The authors were even very careful to point out that their marginal findings of increased deaths from all-causes could not be carried over to healthy individuals. But you didn't hear that on the evening news.
