Preventing the risk of fractures as you grow older is important. Previously, vitamin D and calcium supplements were thought to help reduce that risk – but recommendations have changed.
The Task Force actually recommends against vitamin D in daily doses of 400 IU or less and calcium in daily doses of 1000 mg or less because it can increase the risk of kidney stones. At those doses, supplements do not prevent fractures in younger men and women.
However, the Task Force continues to recommend vitamin D supplements to prevent falls in adults 65 and older who are at higher risk for falls.
