Don't Throw away your calcium supplement just yet but a seven-year study of 36,282 women ages 50 to 79 gave half the participants 1,000 milligrams of calcium and 400 units of vitamin D.

The biggest study ever of calcium and vitamin D supplements for older women showed they offered only limited protection against broken bones, raising questions over what has been an article of faith among doctors and nutritionists
