Question: I have just read the report on the Iowa Women’s Health Study by the Mayo Clinic concerning the dangers of taking vitamins. Can you give me your take on this study?

Dr. Blaylock's Answer:

Virtually all of these studies are epidemiological or population studies, which are almost always poorly done and provide only confusion and few answers.

The problem with such studies is that it is impossible to carefully evaluate tens of thousands of people — especially for factors such as dietary intake, exposure to environmental toxins, pre-existing diseases and toxins, lifestyle habits, and other variables. All of these factors can make a big difference in the study outcome.
As I repeat often, one’s diet is essential to good health, and taking a few vitamins has little effect on health if the diet remains poor. Also, many of these studies use poorly compounded vitamins and only single vitamins, which is just bad science. In addition, many of these studies are generated by pharmaceutical company money to downplay the effectiveness of nutritional supplements, which are direct competitors of drugs.
My advice is to ignore such studies. For every one of these pharmaceutical company-supported studies, there are thousands of well-conducted research studies showing the tremendous benefits of vitamins, as well as proving their safety.
I think many of these articles should be labeled as advertisements.
