Vitamin D - Food Sources and Deficiency Symptoms
It is a fat soluble vitamin that is found in food and can also be made in your body after exposure to ultraviolet rays from the sun. Calciferol is the most active form of vitamin D. The liver and kidney help convert vitamin D to its active hormone form. Once vitamin D is produced in the skin or consumed in food, it requires chemical conversion in the liver and kidney to form 1,25 dihydroxyvitamin D, the physiologically active form of vitamin D.
Vitamin D is a hormone precursor that contributes to the maintenance of normal levels of calcium and phosphorus in the blood. It is a steroid hormone, which play important role in regulating body levels of calcium and phosphorus, and in mineralization of bone.
