Calcium Supplements Thwart Bone Loss - WebMD

Confused about whether calcium supplements and vitamin D supplements protect your bones?
A report in this week's edition of The Lancet sheds new light on that question.
People aged 50 and older who take calcium supplements are 12% less likely to fracture a bone than their peers who don't take those pills.

That protection rate doubles when calcium supplements are taken correctly, report the researchers, who included Benjamin Tang, MD, of the Centre for Complementary Medicine Research at Australia's University of Western Sydney.
