Swiss researchers evaluated monthly high-dose vitamin D supplementation in 200 adults 70 years and older with a history of a fall in the past year. They were randomized to receive one of three monthly regimens, including the control group. At 12 months, lower extremity function was the same in all groups, but fall rates were higher except in the control group. An editorial suggested those over 70 should consume 800 IU daily of vitamin D, preferably from a balanced diet.
PositiveTip: Adequate exposure to sunlight daily, combined with a balanced diet is important to assure sufficient vitamin D.
