Calcium Supplements May Not Be Heart Healthy

Medical Team Looking at Xray Provider

Researchers from Johns Hopkins University School of Medicine have published a study suggesting that dietary calcium supplements—not calcium-rich foods— might harm the heart. That is, excess calcium may harm the heart and vascular system. Given that nearly 43 percent of U.S. adults take a supplement that includes calcium, this study might give pause. More than 2,700 adults between the ages of 45 and 85 were studied. People who took calcium supplements showed a larger risk of arterial plaque buildup and an increase in heart disease risk than people who were not taking supplements.
