A new study showing that taking a multivitamin decreases cancer risk provides insight on how supplemental nutrition in conjunction with healthy lifestyle practices can prevent disease. The study is noteworthy because it was one of the first randomized trials to test multivitamin use in relation to cancer rates in a large population of doctors.
Called the Physicians’ Health Study II and published in the Journal of the American Medical Association, the trial compared the use of a multivitamin with a placebo taken daily for 11 years in men with an average age of 64 at the start of the study. Results showed that the group that took the multivitamin had a statistically significant 8 percent lower risk of developing cancer than the men in the placebo group. .
