A 2010 study suggests “that cardiovascular risks from high calcium intake might be restricted to use of calcium supplements,” according to researchers. Calcium supplementation — without giving vitamin D at the same time — appears to increase the risk of myocardial infarction, a new review of past research has shown. Read Todd Neale’s July 2010 article on this topic. Dr. Ian Reid, MD of the University of Auckland in New Zealand and colleagues reported online in BMJ some years ago,”As calcium supplements are widely used, these modest increases in risk of cardiovascular disease might translate into a large burden of disease in the population,” the researchers wrote. “A reassessment of the role of calcium supplements in the management of osteoporosis is warranted.”
Comments from Physicians on the study
Dr. Stephen Richardson, an endocrinologist at NYU Langone Medical Center,noted that the analysis was limited in that it excluded trials in which calcium supplements were given along with vitamin D.
Dr. John Cleland of the University of Hull in England and colleagues wrote in an accompanying editorial.
“Calcium supplements, given alone, improve bone mineral density, but they are ineffective in reducing the risk of fractures and might even increase risk, they might increase the risk of cardiovascular events, and they do not reduce mortality. They seem to be unnecessary in adults with an adequate diet. Given the uncertain benefits of calcium supplements, any level of risk is unwarranted. Considering the available evidence, patients with osteoporosis should generally not be treated with calcium supplements, either alone or combined with vitamin D, unless they are also receiving an effective treatment for osteoporosis for a recognized indication.”
Dr. Murray Favus, an endocrinologist at the University of Chicago, said, “I am sufficiently concerned to advise those with high calcium supplement intake to limit calcium supplement use in favor of dietary sources until the risk of supplements can be sorted out.”
