Vitamin D is a prohormone, which is the precursor to a hormone. In its raw form (sun exposure, foods, supplements), Vitamin D is inert and has to go through a series of complex biochemical reactions before your body can use it. These reactions produce calcitriol, which is the form of Vitamin D that is used by your body (D2 and D3).

Vitamin D is one of the only vitamins that your body can produce by itself. What is the catalyst that gets your D production going? Good old fashioned sunshine! It’s the ultraviolet-B radiation (UVB) that enables vitamin D production to occur in the skin.

Vitamin D is produced in equal amounts in both people with fairly pigmented and darkly pigmented skin after exposure to UVB radiation (sunlight). Sunlight is important for Vitamin D production, but the strength of sunlight and the intensity of UVB exposure can be affected by season, distance from the equator, and even personal habits. If you have a job that keeps you indoors during daylight hours, or you work nights, you don’t produce as much Vitamin D as someone who is outside for at least ten to fifteen minutes each day.

Vitamin D can be supplemented by eating the right foods. See my previous blogpost about foods containing Vitamin D.

Vitamin D plays an important role in bone building by enabling calcium uptake by your body. It is also very important for healthy immune system function and may help lower your risk of contracting colds. Vitamin D also helps confer innate immunity which may protect your body from the influenza virus.

Vitamin D has been linked to the prevention of many different diseases, including multiple sclerosis, arthritis and even cancer. Children with higher vitamin D levels are less likely to suffer from asthma and allergies than those who are vitamin D deficient. Mental agility might be maintained by adequate levels of the vitamin, especially in the elderly.

Calcium is necessary for maintenance of normal bones and teeth. Vitamin D, whilst aiding in calcium absorption, also contributes to the maintenance of normal bones and teeth.
