AN ESSENTIAL VITAMIN
Vitamin D is a fat soluble vitamin that is very important for maintaining normal levels of calcium and phosphorus in the the blood. Vitamin D has other roles in the body, too, including modulation of cell growth, neuromuscular and immune function, and overall health.*
VITAMIN D SOURCES
Vitamin D encompasses two forms: vitamin D2, which is produced by plants, and vitamin D3, which is synthesized when human skin is exposed to the sun’s ultraviolet B shortwave rays.
A very limited variety of foods contain naturally occurring vitamin D; among them are salmon, mackerel, and some mushroom varieties. Foods is also additionally fortified with vitamin D; these commonly include milk and yogurt, tuna, sardines, beef, eggs, orange juice, and plenty of breakfast cereals. Fortified foods may contain either vitamin D2 or vitamin D3.
VITAMIN D ABSORPTION
Vitamin D obtained from sun exposure, food, and supplements is biologically inert and will have to undergo two chemical processes in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D [25(OH)D], sometimes called calcidiol. The second one occurs primarily in the kidney and forms the physiologically active 1,25-dihydroxyvitamin D [1,25(OH)2D], sometimes called calcitriol.
Vitamin D3, as cholecalciferol, is bioidentical to the vitamin D produced by the human body. Studies have shown that Vitamin D3 increases the total [25(OH)D] concentration more than vitamin D2, suggesting that vitamin D3 is more bioavailable in supplementation.*
