Calcium Not as Great for Bones as Once Thought

The reports, both published today (Sept. 29) in the journal BMJ, looked at the effects of calcium intake on bone density and risk of fracture in adults over age 50. In the first report, researchers analyzed the results of 59 previous randomized controlled trials of calcium involving more than 12,000 people. The investigators found that increasing calcium intake — either through diet or by taking supplements — increased people's bone-mineral density by up to 2 percent.
