Postmenopausal women shouldn’t take low doses of vitamin D and calcium to prevent broken bones, a government-backed expert panel said on Tuesday. The U.S. Preventive Services Task Force (USPSTF), which makes recommendations on a range of prevention issues, said studies of the supplements suggest they do little to prevent fractures at doses lower than 400 IU of vitamin D and 1,000 milligrams (mg) of calcium daily. But it is clear that they come with a slightly increased risk of certain side effects, including kidney stones.
