Daily D and Calcium for Bones

This review of 28 studies covering over 120,000 people found those who combined 800 IU of vitamin D per day along with 1,000 to 1,200 mg of calcium per day, for approximately six years, were 6 percent less likely to have any bone fracture, and were 16 percent less likely to have a fracture of the hip. Doctors said the benefits depended on consuming D and calcium daily, not intermittently.

Also, each increase in circulating vitamin D levels of 10 nanograms per milliliter of blood reduced chances of any bone fracture by 7 percent, and by 20 percent for hip fracture.
