According to two new studies published this week, researchers say multivitamins and supplements do not help prevent heart disease or cancer.

Some researchers went even further, saying consumers should stop wasting their money buying products that do not work.

Winthrop Hospital's Chief of Cardiology Dr. Kevin Marzo says he doesn't think average healthy adults benefit from taking vitamins, but he would like to see more research done.

"I think the important things to reduce risk of heart attack and stroke and cancer is to lead a healthy lifestyle," said Marzo. "Eat your fruit and vegetables. Eat whole grains. Reduce your red meat and exercise every day."
