Summary of “Calcium and vitamin D supplements may not protect against bone fractures”

The conclusion was clear: vitamin D and calcium supplements do not seem to be warranted to prevent bone breaks or hip fractures in those adults.
The U.S. Preventive Services Task Force, an influential federal advisory body, has raised questions about these supplements since 2013, when it issued recommendations saying evidence to support the benefit of the supplements in older adults without osteoporosis or vitamin D deficiency was “Insufficient.”
Vitamin D is not a vitamin but a hormone that is produced in reaction to sunlight and seems to have many different roles in the body related to bones, cancer, heart disease, diabetes, immune function and reproductive health.
Calcium and vitamin D have been known to be important to bone maintenance for a long time, and the best way to get the daily recommended doses are the natural way.
The issue is many Americans don’t get enough calcium or vitamin D – which is why the debate over supplements has become so important.
While that report has few explicit mentions of supplements, the use of supplements seems assumed, and it includes a lot of discussion about the importance of setting and following upper limits for intake of vitamin D and calcium.
“As North Americans take more supplements and eat more of foods that have been fortified with vitamin D and calcium, it becomes more likely that people consume high amounts of these nutrients,” the group wrote, warning of the possibility of kidney and tissue damage from overconsumption.
The new study did not look at the benefits or risks of vitamin D supplements on other conditions, but previous studies have suggested they can lower risks for diabetes and certain cancers.
