Calcitriol

This product is one of the most important metabolic product of vitamin D3, under normal circumstances, calcitriol by its precursor, 25 - hydroxyl bile solidified alcohol in kidney synthesis.
Physiological synthesis of calcitriol daily body is about 0.5 to 1.0 ug.
In bone formation active period (such as growth or pregnancy), its synthetic quantity also increased slightly.
Calcitriol can promote the intestinal absorption of calcium, and adjust the calcification of bone.
For severe renal failure, especially in patients receiving hemodialysis treatment for a long time, the synthesis of endogenous calcitriol significantly reduced or even stopped completely.
The lack of calcitriol for the formation of renal bone dystrophy play a key role.
