Vitamin D is a fat-soluble vitamin that is naturally present in very few foods, added to others, and available as a dietary supplement. It is also produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis [1-3]. Vitamin D obtained from sun exposure, food, and supplements is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], also known as calcidiol. The second occurs primarily in the kidney and forms the physiologically active 1,25dihydroxyvitamin D [1,25(OH)2D], also known as calcitriol.
Vitamin D promotes the absorption of calcium and helps maintain healthy phosphorous levels in the body. It works with a number of other vitamins, minerals and hormones to promote bone mineralization. Cholecalciferol, also known as vitamin D3, is the most active form of calcium. It is manufactured by the body when the skin is exposed to the UV rays of the sun. It may be necessary to supplement this vitamin within the diet due to inclement weather, aging. strict vegetarian (vegan) diets and overactive parathyroid glands.
