  Vitamin D deficiency is a major global, public health problem and is prevalent among all ages and ethnic groups. Nevertheless, it is preventable cost-effectively, if proper public health interventions are implemented. Only a handful of expensive foods contain vitamin D and it is difficulty to change people’s attitude and lifestyles. Therefore, an inexpensive supplements and food-fornication programs have been recommended. More than 80% of the requirement vitamin D should generate from our skin, but sun avoidance behaviors prevent this. The combination of lifestyle and environmental issues, decreased exposures to sunlight have led to vitamin D insufficiency. This affects approximately, 50% of the global population and estimated 1.5 billion people worldwide have vitamin D deficiency [1]. Sunlight remains the primary source of vitamin D3 that is synthesis in dermal tissues in humans and in animals. The details of vitamin D metabolism through sun or by ingested food are shown in figure 1.
