Hydroxycholecalciferol may refer to: 1-Hydroxycholecalciferol (Alfacalcidol) 25-Hydroxycholecalciferol (Calcifediol or calcidiol) 1,25-Dihydroxycholecalciferol

Calcifediol, also known as calcidiol, 25-hydroxycholecalciferol, or 25-hydroxyvitamin D3 (abbreviated 25(OH)D3), is a form of vitamin D produced in the
