    Vitamin D replacement in Asians with diabetes may increase insulin resistance.
    Taylor AV, Wise PH.
    Postgrad Med J. 1998 Jun;74(872):365-6.
    PMID: 9799895

    We report three cases of vitamin D replacement in British Asians with vitamin D deficiency and non-insulin-dependent diabetes mellitus. In all cases, replacement resulted in an increase in insulin resistance and a deterioration of glycaemic control

    Serum levels of free 1,25-dihydroxyvitamin D in vitamin D toxicity.
    Pettifor JM, Bikle DD, Cavaleros M, Zachen D, Kamdar MC, Ross FP.
    Ann Intern Med. 1995 Apr 1;122(7):511-3.
    PMID: 7872586

    CONCLUSIONS: Although the patients had normal or near-normal total 1,25-(OH)2D values, most patients had elevated free 1,25-(OH)2D levels. These findings suggest that elevated free 1,25-(OH)2D levels might play a role in the pathogenesis of hypercalcemia in vitamin D toxicity.

    Vitamin D and diabetes: improvement of glycemic control with vitamin D3 repletion.
    Schwalfenberg G.
    Can Fam Physician. 2008 Jun;54(6):864-6.
    PMID: 18556494

    Conclusion

    These cases support information that is already known about VTD and its effect on the islet cell. As discussed above, this might be true only for vitamin D3 and not vitamin D2, although vitamin D2 has been shown to improve bone health. Vitamin D insufficiency or deficiency is common, and repletion might improve glycemic control early in type 2 diabetes. Diabetes is one of the fastest growing chronic diseases worldwide. Vitamin D3 is inexpensive and readily available. Well-designed clinical studies are required to ascertain if improving 25(OH)D levels from an insufficiency or deficiency to sufficiency improves glycemic control in diabetes. These studies need to be properly designed: a randomized controlled trial with VTD deficiency or insufficiency identified in diabetic patients of various ethnic

The Heart Scan Blog: The case against vitamin D2 - 0 views

  •  
    Why would vitamin D be prescribed when vitamin D3 is available over-the-counter?

    Let's review the known differences between vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol):

    --D3 is the human form; D2 is the non-human form found in plants.

    --Dose for dose, D3 is more effective at raising blood levels of 25-hydroxy vitamin D than D2. It requires roughly twice to 250% of the dose of D2 to match that of D3 (Trang H et al 1998).

    --D2 blood levels don't yield long-term sustained levels of 25-hydroxy vitamin D as does D3. When examined as a 28-day area under the curve (AUC--a superior measure of biologic exposure), D3 yields better than a 300% increased potency compared to D2. This means that it requires around 50,000 units D2 to match the effects of 15,000 units D3 (Armas LA et al 2004).

    --D2 has lower binding affinity for vitamin D-binding protein, compared to D3

    --Mitochondrial vitamin D 25-hydroxylase converts D3 to the 25-hydroxylated form five times more rapidly than D2.

    --As we age, the ability to metabolize D2 is dramatically reduced, while D3 is not subject to this phenomenon
