In this randomized, double-blind, placebo controlled study of approximately 14,641 male physicians ages 50 or older from the United States, participants were randomly assigned to take a daily multivitamin/ mineral supplement or a placebo between 1997 and June 2011. During the median follow-up of 11.2 years, researchers recorded 2,669 cancer cases, including 1,373 prostate cancer cases and 210 colorectal cancer cases. When examining outcomes at the study's end, the researchers found an 8 percent reduction in total cancer occurrence among participants assigned to multivitamin use.
Although the main reason to take multivitamins is to prevent nutritional deficiency, this study reinforces the value of long-term consistent use of a daily multivitamin as a convenient and affordable insurance policy for good health and possible cancer prevention in middle-aged and older adults.
