The body usually gets the required vitamins from food and not getting proper nutrients can increase the risk of developing certain serious diseases.

Vitamins are vital nutrients that are classified as either water-soluble or fat-soluble. There are thirteen types of vitamins and each of them has a distinct job to do. Water soluble vitamins such as Vitamin C and B vitamins are absorbed by our intestines and carried by the blood to specific tissues or organs where they are required.

On the other hand, fat-soluble vitamins, such as A, D, E, and K, take a lot longer to break down and remain in the body for longer periods of time. Unlike water-soluble vitamins, fat-soluble vitamins are not easily lost through either sweating or urinating. The body usually gets the required vitamins from food and not getting proper nutrients can increase the risk of developing certain serious diseases.
