What Is Vitamin D?
Vitamin D is produced on our skin when we are exposed to sunlight. It helps our bodies to absorb calcium and phosphorous for healthy bones. It is also needed to support the immune system.
Why take a Vitamin D supplement?
The most common cause of a vitamin D deficiency is a too low production via the skin as a consequence of insufficient exposure to sunlight due to seasonal variations, the use of sun creams, too little time spent outdoors, or wearing clothes that cover too much the body. Furthermore, the capacity of our skin to produce vitamin D declines as we become older and among people with a darker skin. Another cause of vitamin D deficiency is insufficient absorption as a consequence of a dietary inadequacy or a less efficient absorption from the daily food intake.
