    Effects of vitamin D supplementation on strength, physical performance, and falls in older persons: a systematic review.
    Latham NK, Anderson CS, Reid IR.
    J Am Geriatr Soc. 2003 Sep;51(9):1219-26. Review.
    PMID: 12919233
    DOI: 10.1046/j.1532-5415.2003.51405.

    Conclusion: Although there is insufficient evidence that vitamin D supplementation alone improves physical performance in older people, some data suggest a benefit from vitamin D combined with calcium supplementation, but this requires confirmation in large, well-designed trials.

    Fall prevention with supplemental and active forms of vitamin D: a meta-analysis of randomised controlled trials.
    Bischoff-Ferrari HA, Dawson-Hughes B, Staehelin HB, Orav JE, Stuck AE, Theiler R, Wong JB, Egli A, Kiel DP, Henschkowski J.
    BMJ. 2009 Oct 1;339:b3692. doi: 10.1136/bmj.b3692.
    PMID: 19797342
    doi: 10.1136/bmj.b3692

    Conclusions Supplemental vitamin D in a dose of 700-1000 IU a day reduced the risk of falling among older individuals by 19% and to a similar degree as active forms of vitamin D. Doses of supplemental vitamin D of less than 700 IU or serum 25-hydroxyvitamin D concentrations of less than 60 nmol/l may not reduce the risk of falling among older individuals.

Over 65? Take lots of vitamin D to prevent a fall: MedlinePlus - 0 views

  •  
    "NEW YORK (Reuters Health) - Important news for seniors: A daily dose of vitamin D cuts your risk of falling substantially, researchers reported today.

    But not just any dose will do. "It takes 700 to 1000 international units (IU) of vitamin D per day and nothing less will work," Dr. Heike A. Bischoff-Ferrari, who directs the Center on Aging and Mobility at the University of Zurich, Switzerland, noted in an email to Reuters Health.

    Those recommendations - which are higher than those by the U.S. Institute of Medicine -- are based on the results of eight studies that looked at vitamin D supplements for fall prevention among more than 2,400 adults aged 65 and older. Falls were not notably reduced with daily doses of vitamin D lower than 700 IU.

    An analysis of all eight studies, posted online today in the British Medical Journal, add weight to several others which have shown that vitamin D improves strength and balance, and bone health in the elderly, the researchers note."

    Effects of vitamin D and calcium supplementation on falls: a randomized controlled trial.
    Bischoff HA, Stähelin HB, Dick W, Akos R, Knecht M, Salis C, Nebiker M, Theiler R, Pfeifer M, Begerow B, Lew RA, Conzelmann M.
    J Bone Miner Res. 2003 Feb;18(2):343-51.
    PMID: 12568412

    A single intervention with vitamin D plus calcium over a 3-month period reduced the risk of falling by 49% compared with calcium alone. Over this short-term intervention, recurrent fallers seem to benefit most by the treatment. The impact of vitamin D on falls might be explained by the observed improvement in musculoskeletal function.

    Vitamin D supplementation improves neuromuscular function in older people who fall.
    Dhesi JK, Jackson SH, Bearne LM, Moniz C, Hurley MV, Swift CG, Allain TJ.
    Age Ageing. 2004 Nov;33(6):589-95.
    PMID: 15501836
    doi:10.1093/ageing/afh20 9

    CONCLUSIONS: vitamin D supplementation, in fallers with vitamin D insufficiency, has a significant beneficial effect on functional performance, reaction time and balance, but not muscle strength. This suggests that vitamin D supplementation improves neuromuscular or neuroprotective function, which may in part explain the mechanism whereby vitamin D reduces falls and fractures.
