So Why Are Most Prescription Supplements Vitamin D2? Hence the study’s conclusion that ergocalciferol should not be used as a supplement. In fact, D2 and D3 are metabolized so differently that they result in “the production of unique biologically active metabolites.” 1Ĭlearly, these forms of Vitamin D are simply not the same. It takes much longer to make this hepatic conversion with Vitamin D2. In the liver, thanks to a particular hepatic enzyme, Vitamin D3 is more readily metabolized into a bioactive form of D that is easily converted to its hormone form in the kidneys. There are several biological mechanisms that contribute to the superior absorbability and efficacy of Vitamin D3. “… ergocalciferol should not be regarded as a nutrient suitable for supplementation or fortification.” 1 However, the inefficiency of vitamin D2 compared with vitamin D3, on a per mole basis, at increasing 25(OH)D is now well documented, and no successful clinical trials to date have shown that vitamin D2 prevents fractures.” 1 (emphasis added) “Vitamin D2, if given in high enough doses, prevents infantile rickets and is capable of healing adult osteomalacia. Study Proves The Inadequacy Of Vitamin D2 (And The Superiority Of D3)Ī report published in The American Journal of Nutrition points out the very clear difference between Vitamin D3 and Vitamin D2, the latter, the “form of vitamin D used in major preparations of prescriptions in North America.” 1 Vitamin D2 is in fact not the bioavailable equivalent of D3. Today, you’ll learn the difference between these two forms of Vitamin D and why you should take D3 and never D2. You see, if your blood test results have shown that you are Vitamin D deficient, chances are your doctor prescribed Vitamin D2 (ergocalciferol) supplements instead of D3 (cholecalciferol). Today I am going to share with you some crucial but little-known information about Vitamin D that your doctor simply won’t tell you.
