Multivitamins don’t guard against heart attack
A vitamin a day may have its benefits, but protecting against a cardiovascular crisis isn’t one of them. That’s the conclusion of researchers who randomly assigned more than 14,000 men age 50 and older to get a multivitamin or placebo. After 11 years, both groups of men had a similar risk of a heart attack, stroke or of dying of a heart-related event. About one-third of U.S. adults take a multivitamin, said Howard Sesso, an epidemiologist at Harvard Medical School and Brigham and Women’s Hospital in Boston. The study, which Sesso presented November 5, is the first long-term trial to assess whether multivitamins have a cardio-protective role. “The main reason to take multivitamins remains to prevent vitamin and mineral deficiency,” he concluded. The study also appears in the Nov. 7 Journal of the American Medical Association.
