Daily supplementation with high-dose vitamin D (700-1000 IU) appears to substantially reduce the risk of falling among older adults, report scientists in Switzerland and the United States (Bischoff-Ferrari HA et al. BMJ. doi:10.1136/bmj.b3692 [published online October 1, 2009]).
The researchers analyzed the results of 8 randomized controlled trials to assess the effectiveness of various doses of vitamin D in preventing falls in more than 2400 persons aged 65 years or older. Participants received a defined oral dose of supplemental vitamin D3 or vitamin D2 or an active form of vitamin D.
