VITAMIN D (CALCIFEROL) – The Sunshine Vitamin Vitamin D is insoluble in water and cannot be easily destroyed by heating.
This vitamin is absorbed in the jejunum of small intestine and is transported to the blood stream. Vitamin D is stored in the bones, brain, liver and skin. Functions in the Body
During childhood and adolescent period Vitamin D is needed for the proper formation of bones and teeth. It also prevents dental caries. Parathyroid gland regulates the calcium level in the blood, and for healthy functioning Vitamin D is essential.
Satisfactory future development of the child is assured when a pregnant mother takes a good supply of this vitamin. It also protects against rickets and assists assimilation of calcium, phosphorus and other minerals in the digestive tract. Sources
