Vitamin D (Cholecalciferol)

Vitamin D is also known as calciferol because of its role in calcium metabolism and antirachitic factor because it prevents rickets.
Other name is SUNSHINE Vitamin

Cholecalciferol is an inactive form of vitamin D.
It needs further metabolism to produce the active form of the vitamin.
1, 25 dihydroxycholecalciferol also known as calcitriol is the active form of vitamin D.
