And there's evidence that another supplement, vitamin K2, can "help the calcium go to the bone rather than the heart," Kapadia added. He noted that vitamin D - which your body requires for bone to absorb calcium - by itself did not cause any heart health problems among the patients in his study. Kapadia said that aging people would be better off getting their recommended calcium through their diet, and should talk to their doctor about their bone health concerns. "We would do well to remember that 'more' is not always 'more' - supplements can be double-edged swords," Tomey concluded. "The findings of the study are nonetheless hypothesis-generating and underscore the need for a randomized study of benefits and risks of commonly used supplements for cardiovascular health," Tomey said. However, he cautioned that since this is an observational study, it cannot establish a clear cause-and-effect link between calcium supplements and heart valve problems. Matthew Tomey, a cardiologist with Mount Sinai Morningside in New York City, noted that the development of aortic stenosis closely resembles the way bone normally forms.īecause of that, "the concept of calcium supplementation as a modifier of aortic stenosis disease progression is interesting," said Tomey, who wasn't involved in the study. The results were published online Monday in the BMJ.ĭr. Supplemental calcium plus vitamin D increased risk of death from any cause by 31%, while calcium alone was linked to a 24% higher risk of all-cause mortality, the study found. (Person-years is the product of number of years times number of members of a population who have been affected by a certain condition.) The study found that people taking calcium with vitamin D had an absolute risk of heart-related death of 13.7 deaths per 1,000 person-years, compared with 5.8 deaths per 1,000 person-years in people not taking any supplements. Patients were divided into those taking calcium, those taking calcium plus vitamin D, and those not taking any supplements. ![]() ![]() ![]() The patients' average age was 74, and they were tracked more than 5.5 years on average.
