|'''[[Calcium#Calcitriol (Active Vitamin D3)|Calcitriol]]'''

|Also known as ''Active Vitamin D3'', or ''1-25-Dihydroxyvitamin D3'', Calcitriol is vital for [[Calcium|Calcium Homeostasis]], and acts to raise plasma calcium levels. Within the kidney, vitamin D from dietary sources or the skin is 'activated' by hydroxylation.
