Multivitamins may not be the answer in preventing heart disease a new study found.
Researchers at Brigham Women's Hospital and Harvard Medical School found that men who took multivitamins over the long-term found no benefit for preventing cardiovascular issues.
The study looked at 15,000 physicians over the age of 50 participating in a research project called the Physicians Health Study, which looks at a number of indicators over decades, said WebMD.
According to Time, none of the participants knew they were taking the placebo or the multivitamin.
During the over a decade-long study, 2,757 of the men (18.8 percent) died of heart disease.

The deaths included 1,345 of the men taking vitamins and 1,412 of the men taking the placebo, said AFP.
Researchers said it was the first large study to test the effectiveness of multivitamins for cardiovascular issues.
"The main reason to take a daily multivitamin ... remains to prevent vitamin and mineral deficiency,'' said study author Howard Sesso, an epidemiologist at Brigham and Women's Hospital and Harvard Medical School, reported WebMD.
"There is no reason to recommend multivitamins for cardiovascular disease."
The study was published in the journal of the American Medical Association (JAMA)
