What is 25-hydroxy calcifediol? The precursor of 25-hydroxy calcifediol, which is also known as cholecalciferol in medicine, is vitamin D3, which can be obtained by hydroxylation of 25-hydroxy calcifediol, which has biological activity. It is also the main form of vitamin D3 stored in our bodies. It is also an important intermediate in vitamin D metabolism. The 25-hydroxy calcifediol is stable and vitamin D itself has no biological activity. Vitamin D can only play its biological role when transformed into 25-hydroxy calcifediol.
The absorption effect of 25-hydroxy calcifediol in the human body is superior to that of vitamin D3, which can be directly absorbed into the intestinal tract and enter the blood circulation, effectively improving the level of 25-hydroxy calcifediol in the blood. For the human body, 25-hydroxy calcifediol maintains normal development, bone and muscle function, etc. Therefore, it is very important for maintaining good health.
