Vitamin D May Cut Elders' Falls
Fewer Falls Seen in Elderly Taking High Vitamin D Dose
The nursing home was required to keep records of residents' falls. During

than those taking the placebo.
None of the other vitamin D doses were associated with reduced falls.
These results held when the researchers took age, BMI (body mass index), and
other factors into account.
People can fall for many reasons; and it's not certain vitamin D was the

Vitamin D is one vitamin you shouldn't overdo. The body stores vitamin D in
