24,25-Dihydroxycholecalciferol, also known as 24,25-dihydroxyvitamin D₃, refers to a mixture of epimers (24R)-hydroxycalcidiol and (24S)-hydroxycalcidiol (abbreviated as 24(R),25-(OH)₂D₃ and 24(S),25-(OH)₂D₃) closely related to 1,25-dihydroxyvitamin D₃, the active form of vitamin D₃. Like vitamin D₃ itself and calcifediol (25-hydroxyvitamin D₃), it is inactive as a hormone both in vitro and in vivo. It was first identified in 1972 in the laboratory of Hector DeLuca and Michael F. Holick.
