Middle-aged male doctors who took a daily multivitamin were less likely to develop cataracts as they grew older, according to the Physicians’ Health Study II.
In this large study, more than 5700 men took a Centrum Silver daily and a similar number took placebo. These volunteers filled out annual questionnaires about their health between 1997 and 2011. Those on the multivitamin lowered their risk of cataracts by 9 percent during that time. The benefit was most apparent among older men, perhaps because their risk of cataracts is highest.
