Calcium supplements: A risk factor for heart attack?

Over the years, many studies have suggested that women who have a higher calcium intake experience not only improved bone health but also a lower risk of cardiovascular disease. One recent study, however, raised questions about the protective effect of calcium supplements on cardiovascular disease. The study — which was published February 2008 in BMJ — was done primarily to evaluate the effect of calcium supplementation on bone density and bone fracture in elderly women. Later, however, the results were reanalyzed to note the occurrence of cardiac events among study participants. Although more heart attacks occurred in women who took calcium supplements, the statistical analysis indicated that the difference could have been due to chance. Also, a similar placebo-controlled study of calcium supplementation showed no increase in the risk of heart attack or other cardiovascular disease in women taking calcium. Current recommendations regarding calcium supplementation haven't changed because of this study. As with any health issue, it's important to consult your doctor to determine what's best in your case. Many factors may influence your specific needs for calcium.
