Older Adults May Need More Vitamin D to Prevent Mobility Difficulties

Older adults who don't get enough vitamin D - either from diet, supplements or sun exposure - may be at increased risk of developing mobility limitations and disability, according to new research from Wake Forest Baptist Medical Center.

Vitamin D Supplements Could Help Reduce Falls in Homebound Elderly

Every year falls affect approximately one in three older adults living at home, with approximately one in 10 falls resulting in serious injury. Even if an injury does not occur, the fear of falling can lead to reduced activity and a loss of independence. Research has shown that vitamin D plays a key role in maintaining muscle integrity and strength and some studies suggest vitamin D may reduce the risk of falls.
