Description
White odorless solid; [CAMEO] White powder; [Sigma-Aldrich MSDS]
Sources/Uses
Synthetic form of vitamin D used as a rodenticide and therapeutic vitamin; [Merck Index] Used as a nutritional supplement; [FDA] "Ergocalciferol may be used as a vitamin D supplement, and a 2011 clinical guideline considered it to be as effective as cholecalciferol (vitamin D3), which is produced naturally by the skin when exposed to ultraviolet light. Conflicting evidence exists for how similarly D2 and D3 behave in the body and whether they are equally active, with preliminary studies suggesting D3 is more potent, while others report equal efficacy." [Wikipedia]
