Vitamin D is a group of compounds known as secosteroids. These compounds are fat-soluble and responsible for maximizing the intestinal absorption of essential minerals like zinc, magnesium, calcium and phosphate as well as other beneficial health effects like reduction of the risk of colon cancer. Vitamin D includes Vitamin D2 and D3 and is present naturally in some foods. It is usually spiked, fortified, or added to other foods and is endogenously produced by the sun’s UV light when these rays strike the skin starting the synthesis of this vitamin.
