Multivitamin Intake Yields Mixed Results

Men who took a daily multivitamin had a reduced risk for cancer, according to a study published in this week's Journal of the American Medical Association. After an average 11-year follow-up, researchers from Harvard's Physicians' Health Study II found a modest reduction in risk for total cancer among 14,641 men who took a multivitamin. The benefit was seen both among men who were cancer survivors and men who had never had cancer.

When looking at the same group of men taking multivitamins, researchers found no benefit for heart health.
