Ercalcidiol is a vitamin D2 metabolite used as a vitamin D nutritional status indicator. Differentiation between Ercalcidiol (25(OH)D₂) and 25(OH)D₃ is important for monitoring vitamin D therapy, as vitamin D₂ is the predominant prescription form. Ercalcidiol has a shorter half-life and binds less well to the vitamin D binding protein, making it less potent and requiring higher doses than vitamin D₃. Some assays have diminished capacity to detect Ercalcidiol, risking dangerous overdosing when monitoring vitamin D₂ therapy.
