    Yin L, Raum E, Haug U, Arndt V, Brenner H.
    Cancer Epidemiol. 2009 Dec;33(6):435-45. Epub 2009 Nov 25.
    PMID: 19939760
    doi:10.1016/j.canep.2009.10.014

    CONCLUSIONS: According to available evidence from longitudinal studies, serum 25(OH)D is not associated with PC incidence.

    Benefit-risk assessment of vitamin D supplementation.
    Bischoff-Ferrari HA, Shao A, Dawson-Hughes B, Hathcock J, Giovannucci E, Willett WC.
    Osteoporos Int. 2009 Dec 3. [Epub ahead of print]
    PMID: 19957164

    Conclusion Our analysis suggests that mean serum 25(OH)D levels of about 75 to 110 nmol/l provide optimal benefits for all investigated endpoints without increasing health risks. These levels can be best obtained with oral doses in the range of 1,800 to 4,000 IU vitamin D per day; further work is needed, including subject and environment factors, to better define the doses that will achieve optimal blood levels in the large majority of the population.

    Breast Cancer Res Treat. 2009 Oct 23. [Epub ahead of print]
    PMID: 19851861

    These results provide strong evidence that vitamin D and calcium have a chemopreventive effect against breast cancer.

    Vitamin D and prevention of breast cancer: pooled analysis.
    Garland CF, Gorham ED, Mohr SB, Grant WB, Giovannucci EL, Lipkin M, Newmark H, Holick MF, Garland FC.
    J Steroid Biochem Mol Biol. 2007 Mar;103(3-5):708-11.
    PMID: 17368188

    CONCLUSIONS: Intake of 2000 IU/day of Vitamin D(3), and, when possible, very moderate exposure to sunlight, could raise serum 25(OH)D to 52 ng/ml, a level associated with reduction by 50% in incidence of breast cancer, according to observational studies.

    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.

    Aliment Pharmacol Ther. 2009 Jul 1;30(2):113-25. Epub 2009 Apr 15.
    PMID: 19392870
    DOI: 10.1111/j.1365-2036.2009.04022.x

    Conclusions Our results support suggestions that serum 25(OH)D is inversely related to CRC risk.

    Fracture prevention with vitamin D supplementation: a meta-analysis of randomized controlled trials.
    Bischoff-Ferrari HA, Willett WC, Wong JB, Giovannucci E, Dietrich T, Dawson-Hughes B.
    JAMA. 2005 May 11;293(18):2257-64. Review.
    PMID: 15886381

    Conclusions Oral vitamin D supplementation between 700 to 800 IU/d appears to reduce the risk of hip and any nonvertebral fractures in ambulatory or institutionalized elderly persons. An oral vitamin D dose of 400 IU/d is not sufficient for fracture prevention.

    Vitamin D supplementation and total mortality: a meta-analysis of randomized controlled trials.
    Autier P, Gandini S.
    Arch Intern Med. 2007 Sep 10;167(16):1730-7. Review.
    PMID: 17846391

    Conclusions Intake of ordinary doses of vitamin D supplements seems to be associated with decreases in total mortality rates. The relationship between baseline vitamin D status, dose of vitamin D supplements, and total mortality rates remains to be investigated. Population-based, placebo-controlled randomized trials with total mortality as the main end point should be organized for confirming these findings.

    .CONCLUSIONS: Vitamin D and calcium insufficiency may negatively influence glycemia, whereas combined supplementation with both nutrients may be beneficial in optimizing glucose metabolism.

    Arch Intern Med. 2009 Mar 23;169(6):551-61.
    PMID: 19307517

    Conclusion Nonvertebral fracture prevention with vitamin D is dose dependent, and a higher dose should reduce fractures by at least 20% for individuals aged 65 years or older.
