Calcifediol, also known ascalcidiol,25-hydroxycholecalciferol, or25-hydroxyvitamin D3(abbreviated25(OH)D3),is a form ofvitamin Dproduced in theliverbyhydroxylationofvitamin D3(cholecalciferol) by the enzymevitamin D 25-hydroxylase.Calcifediol can be further hydroxylated by theenzyme25(OH)D-1α-hydroxylase, primarily in the kidney, to formcalcitriol(1,25-(OH)2D3), which is the activehormonalform of vitamin D.
Calcifediol is strongly bound in blood by thevitamin D-binding protein.Measurement of serum calcifediol is the usual test performed to determine a person's vitamin D status, to showvitamin D deficiencyor sufficiency.Calcifediol is available as an oral medication in some countries to supplement vitamin D status.
