Vitamin D and calcium supplements: Take them or leave them?
How to follow the changing recommendations without making yourself dizzy.
First we were advised to take calcium and vitamin D supplements to strengthen our bones and protect against fractures. Then in June, the U.S. Preventive Services Task Force recommended against low-dose calcium and vitamin D supplements, citing little evidence that they actually prevent fractures and noting that they can increase the risk of kidney stones.
A European study added another dose of bad news, linking calcium supplements with a greater risk for heart attacks. Then the tides shifted again, when another analysis suggested calcium and vitamin D supplements might help older adults live longer.
