The report notes a downside to low-dose supplementation: Taking 400 IU or less of vitamin D and 1,000 mg or less of calcium increases the risk of kidney stones, which can be painful and may require hospitalization.

Criticism about the USPSTF guidelines comes from a range of perspectives.

The Council for Responsible Nutrition, a trade association representing the dietary supplement industry, criticized the USPSTF for relying too heavily on data from the Women's Health Initiative (WHI), a study that showed little to no effect on fracture rates in the more than 35,000 postmenopausal women in the trial. They also said that the task force ignored a WHI study out this year that showed a notable reduction in fracture among women who adhered to prescribed doses of calcium and vitamin D.

Some experts prefer a report released by the Institute of Medicine (IOM), a nonprofit organization that gives expert, evidence-based advice on public health issues to policy makers and health professionals.

"That took a very in-depth and I would say a very broad look at the vitamin D and calcium question," said Dr. Sundeep Khosla, a past president of the American Society for Bone and Mineral Research and an endocrinologist and research scientist at the Mayo Clinic. The IOM recommended that most adults get 1,000 mg of calcium, and that women older than 50 and men older than 70 get 1,200 mg of calcium, according to Khosla.

Khosla said the IOM and the USPSTF were each "looking at different parts of the elephant." He said that the USPSTF was focused just on what it took to prevent fracture, ignoring the fact that among healthy people who haven't yet had a break, it would be difficult to detect whether supplements are effective.

"With the IOM taking the physiological perspective, their work might be considered more sensitive [more able to pick up potential benefits or risks]," he said

Marion Nestle, a professor of nutrition, food studies and public health at New York University, co-wrote a journal editorial suggesting that statements from the task force are unlikely to settle the ongoing debate about the use of vitamin D and calcium. "The task force looks at one or two nutrients and one condition at a time, but that's not how people eat or live," she said.
