Paris: Ordinary calcium supplements taken by the elderly to strengthen bones may boost the risk of heart attacks, according to a study released on Friday.The findings, published in the British Medical Journal, suggest that the role of calcium in the treatment of osteoporosis should be reconsidered, the researchers said.
The link was consistent across trials and was independent of age, sex, and type of supplement.While the added risk is modest for any individual, the widespread use of calcium supplements could translate into a significantly larger disease burden across an entire population, the authors warn.Previous studies have found that upping calcium intake through changes in diet does not increase cardiovascular problems, suggesting that the risks are restricted to supplements.In a commentary, John Cleland of the University of Hull in Britain and colleagues point out that -- regardless of possible impacts on heart attack rates -- calcium supplements are probably not very efficient in reducing fractures in any case.Bureau Report
