Vitamin D is normally obtained from the diet or produced by the skin from the ultraviolet energy of the sun. Seasonal difference in sunlight, geographic location, age, the use of sunscreens and clothing to block UV light, and skin pigmentation all influence the cutaneous production of vitamin D.

Because of this and the fact that Vitamin D is not abundant in foods, supplementation becomes even more necessary to ensure that the body is receiving an adequate supply.  Vitamin D3 (as Cholecalciferol) is the most readily absorbed and utilized by the body, and has extremely low toxicity.
