Vitamin D is a fat-soluble vitamin that is naturally present in some foods and added to other foods. It is also known as calciferol. It is also produced by sunlight on the skin which triggers Vitamin D synthesis.  

Vitamin D Deficiency is caused by the lower intake levels of Vitamin D in the body. This happens when sunlight exposure is limited and the kidneys cannot convert the inactive form of Vitamin D into the active form or when absorption of vitamin D is hindered. It is also known as Hypovitaminosis D

A lack of vitamin D can cause many health problems over time.  Vitamin D is an important nutrient that performs multiple functions including bone health, and calcium absorption.
