Question

Is Vitamin D a micronutrient?

Answer 1

Vitamin-D:

1. It is a fat-soluble vitamin that can either be obtained from food sources or synthesized in the human body.
2. The UV rays of the sun are a major source of vitamin D as they trigger vitamin-D synthesis.
3. Vitamin D undergoes hydroxylation in the human body for activation.
4. Initially, Vitamin D is converted into calcidiol in the liver, and the second hydroxylation happens in the kidney, where calcidiol is converted to form calcitriol, the physiologically active form of Vitamin D.
5. Vitamin D is an essential micronutrient required for the maintenance of healthy bones.
6. It promotes calcium absorption, and its deficiency causes the bones to become thin and brittle.
