Not enough vitamin D: Health consequences for Canadians -- Schwalfenberg 53 (5): 841 --... - 0 views

    Not enough vitamin D: health consequences for Canadians.
    Schwalfenberg G.
    Can Fam Physician. 2007 May;53(5):841-54. Review
    PMID: 17872747


    Low levels of VTD are considered a major public health problem in Canada, especially during the winter. Those with risk factors should be screened for low 25(OH)D levels and repletion therapy instituted if needed. Researchers have estimated that the oral dose of vitamin D3 to attain and maintain 25(OH)D levels >80 nmol/L is 2200 IU/d if baseline levels are 20 to 40 nmol/L, 1800 IU/d if levels are 40 to 60 nmol/L, and 1160 IU/d if levels are between 60 and 80 nmol/L.64

    We need to ensure that patients have healthy blood levels of 25(OH)D to prevent levels of parathyroid hormone from rising and to maximize absorption of calcium, magnesium, and phosphate. Positive effects on bone are marginal at best unless patients consume at least 800 IU/d of VTD. The emerging and exciting role of the VTD receptor and the actions of VTD in maintaining health in other cell types have become more apparent during the last decade.

Low Vitamin D Hurts Teenagers' Hearts - 0 views

    March 11, 2009 -- Low vitamin D levels greatly increase a teenager's risk of diabetes and heart disease, Johns Hopkins researchers find.

    It is becoming clear that adults who get too little vitamin D are at higher risk for diabetes and heart disease. Now, it appears vitamin D levels also affect these risks earlier in life, say Johns Hopkins researchers Jared P. Reis, PhD, and colleagues.
