Certain factors such as amount of melatonin, lack of sunshine and certain lifestyles can diminish Vitamin D stored within the body.

Supplementation with Vitamin D alongside a healthy diet can contribute to the normal absorption and utilization of calcium and phosphorus (which contribute to normal bones and normal teeth). Vitamin D is also used within the body for the normal function of the immune system. Vitamin D also contributes to normal blood Calcium levels and has a role in cell division.
