Vitamin D reduces the risk of falls in older adults

elderly fallResearchers from the University Hospital Zurich, in Switzerland reviewed the evidence.

First, the details.

  • Data from 8 well-designed studies of older people receiving a defined oral dose of supplemental vitamin D were combined for a meta-analysis.
    • Vitamin D3 (cholecalciferol) or vitamin D2 (ergocalciferol)
    • Or, an active form of vitamin D (1{alpha}-hydroxyvitamin D3 (1{alpha}-hydroxycalciferol) or 1,25-dihydroxyvitamin D3 (1,25-dihydroxycholecalciferol)

And, the results.

  • High doses of vitamin D (700-1000 IU a day) reduced fall risk by 19%.
  • Those people with blood levels of 25(OH)D concentrations of 60 nmol/L or higher had a 23% fall reduction.
  • Falls were not reduced by low doses (less than 700 IU/day supplemental vitamin D or by blood 25-hydroxyvitamin D concentrations of less than 60 nmol/day.
  • Active forms of vitamin D reduced fall risk by 22%.

The bottom line?
The authors tell us that these findings support earlier study results.

Active forms of vitamin D do not appear to be more effective for fall prevention than 700-1000 IU of supplemental vitamin D.
