New Study Reaffirms Calcium Safety for Heart Health

Washington, D.C., October 11, 2016In response to a study, “Calcium Intake from Diet and Supplements and the Risk of Coronary Artery Calcification and its Progression among Older Adults: 10-year Follow-up of the Multi-Ethnic Study of Atherosclerosis (MESA),” published today in the Journal of the American Heart Association, the Council for Responsible Nutrition (CRN), the leading trade association for the dietary supplement and functional food industry, issued the following statement:

Statement by Duffy MacKay, ND, senior vice president, scientific & regulatory affairs, CRN: 

“This observational study demonstrated that people with the highest total calcium intake from both food and dietary supplements had the lowest risk of coronary artery calcification. This confirms the safety of calcium supplementation for heart health, which has been the conclusion of several large studies1, 2, 3, 4, 5 in recent years. Consumers should have confidence in the safety of calcium supplements, and women in particular should be aiming to get the targeted daily amount of calcium through a combination of diet and supplementation.”
