It's true we don't lead a cool down or even suggest one. You know what's sore and what part of you needs some attention. Spend the time taking care of yourself. Your body will thank you (tomorrow) We can guide you.
Do you need a supplement?
Two studies released this week provide additional evidence that vitamin supplements are potentially harmful and, at the very least, do no good.
This depressing news comes from the Iowa Women's Health Study. Older women in the study who took supplements ranging from multivitamins to high doses of single nutrients had a greater risk of dying than those who did not.
Equally depressing are the results of a trial of high-dose vitamin E and selenium versus prostate cancer. It found higher rates of the cancer among men taking vitamin E (selenium was somewhat protective). In this trial, it was so obvious that the supplements did not protect against prostate cancer that the investigators ended it before its scheduled date of completion.
USA Today interviewed me and Dr. Jeffrey Blumberg (Tufts University) about our interpretations of these trials.
I think that the main conclusion to be drawn from this research is that supplements do not make healthy people healthier. They may not cause harm at high doses, but they appear not to do good.
I don't take them and I don't recommend them -- except to people who have diagnosed nutrient deficiencies or other problems handling nutrients.
Dr. Blumberg, in contrast, thinks multivitamins constitute a useful nutrition insurance policy and everybody should be taking them.
