Question

What Is The Role Of Vitamin D In Calcium Absorption?

Answer 1

Vitamin D:

1. Vitamin D is essential to trigger calcium absorption from the intestine and kidneys.
2. This is found in milk products.
3. Precursors to vitamin D are formed in the skin and then processed in the liver.
4. The last stage in the conversion of an inactive form to an active form occurs in the proximal tubules of kidney cells.
5. Upon activation, vitamin D triggers calcium absorption from the intestine and proximal tubule hence an increase in the levels of blood calcium absorption.
