The Vitamin Myth: Why We Think We Need Supplements

On October 10, 2011, researchers from the University of Minnesota found that women who took supplemental multivitamins died at rates higher than those who didn't. Two days later, researchers from the Cleveland Clinic found that men who took vitamin E had an increased risk of prostate cancer. "It's been a tough week for vitamins," said Carrie Gann of ABC News.

Seven previous studies had already shown that vitamins increased the risk of cancer and heart disease and shortened lives.

In May 1980, during an interview at Oregon State University, Linus Pauling was asked, "Does vitamin C have any side effects on long-term use of, let's say, gram quantities?" Pauling's answer was quick and decisive. "No," he replied.

Seven months later, his wife was dead of stomach cancer. In 1994, Linus Pauling died of prostate cancer.
