An Insight Into The “Sunshine Vitamin”
Vitamin D is popularly known as the “sunshine vitamin” as it is produced in the skin when exposed to sunshine. It is a fat-soluble vitamin and belongs to the family of compounds of vitamins D-1, D-2 and D-3.
Vitamin D can be derived through specific supplements and food to ensure you get adequate amounts of it in the blood. This vitamin has multiple functions and the most vital of them all are the regulation of phosphorus and calcium along with the control of the normal functions of your immune system.
