I have a prostate issue at 67 years old. Right now it was prostatitis & not yet diagnosed further. I am taking various natural high grade supplements. I eat organically and am a vegetarian. I exercise every day. I was taking two 400 IUs of a Vit E supplement. Half before bedtime along with a preventive cardio supplement that contains nattokinase and amla. I am not yet sure but it seemed that my prostate may have been more troublesome when taking the Vit E. That is what led me to post the question. My case is not scientific & I take other supplements during the day. So it is difficult to know. I just felt that the Vit E might be a factor in the inflamation. I am checking this out further but was surprised when I googled the question that there was a Harvard study out there that came to a conclusion (possibly erroneously) that there was a negative connection between prostate cancer risk and Vit E usage. I agree with the comments made that there may be other variables with that study but I was not aware of that study when I posed my question.

Unfair to say that Vitamin E is the culprit for the increase risk of prostrate cancer. How about the lifestyle of those men participated in the study? How about the alcohol intake? Is he a smoker? or other factors and genetics. This study is totally rubbish and will not stand any scientific evidence!

This article is full of partial. incomplete, and very misleading statements. It was obviously written by someone with an agenda to promote synthetic drugs and to discourage taking supplements. Some supplements are indeed worthless, or nearly so, but unless taken in serious excess are highly unlikely to be harmful. The ONLY way to tell if supplements are advisable is by having periodic blood tests. Yes, blood tests cost money (which may or may not be covered by your insurance) and require having a needle stuck into your arm but if you are serious about achieving and maintaining your good health this will not be an impediment.

I agree with ClaudeA. We are not told what vitamin E was used and how much, and the way they come up with numbers…

17% are more likely to get cancer.. How many people, where were these people geographically located, what water did they drink, what kind of diet have they followed besides vitamin E, stress factors.. etc..

For all we know, they might have had the prostate cancer due to not enough sun light. I’m sorry Martin, but this kind of research is completely useless and does not sound unbiased and scientific at all.

How much vitamin E are we talking about? My husband is taking a suppliment that has vitamin E i it.. I believe it is 100mg.

Your comment is based upon pseudoscience and alternative facts, whereas the study cited draws its conclusions from a set of objective and unbiased scientific data.

Sadly, as usual for the promoters of toxic, synthetic meds manufactured by big pharma, this “research fails to specify the actual vitamin E combination that was used. There are over 100 combinations of vitamin E in its 8 natural elements and the toxic, synthetic poor mimic that these deceiving pharmacologists concoct, adding at least that number of variables to the fray.

Therefore, this proposed study is utterly moot. Based on zilch.
