A Daily Multivitamin Reduces Cancer Risk in Older Men
By Olivia B. Waxman October 18, 2012
There hasn’t been strong evidence to support the idea that vitamins can combat cancer—until now.
In the first rigorous, long-term study of multivitamins and their effect on cancer, older men who took daily vitamins lowered their risk of cancer by 8% compared to men who skipped the supplements over an average of 11 years of follow up.
Participants included 14,641 male U.S. male physicians ages 50 and over for 11 years enrolled in the Physicians’ Health Study. The men were randomly assigned to take a multivitamin —Centrum Silver — or a placebo, and neither they nor the scientists were aware of their status. Overall, they were healthy; two-thirds exercised on a regular basis and only 4% were current smokers. The doctors’ mean age was 64. Nine percent (1,312) reported a history of cancer (excluding nonmelanoma skin cancer).
