Taking a daily supplement with at least 800 international units (IU) of vitamin D is recommended for people age 65 and older who are recovering from a bone fracture. Coupled with that is recommended calcium intake of 1,200 milligrams (mg) daily, with diet preferably supplying most or all of this amount and calcium supplements used to fill any gaps. For example, most Americans get about 500 to 700 mg of calcium daily in their diets, so calcium supplementation of around 500 to 700 mg daily would bridge the gap toward the 1,200 mg goal.
