What is Vitamin D
Vitamin D is an essential, fat-soluble vitamin. Fat-soluble vitamins are absorbed along with dietary fats, and are stored in the liver and body fat.
Within food and supplements, there are two forms of vitamin D: vitamin D2 and vitamin D3. It is most often found in the form of vitamin D3, otherwise known as cholecalciferol. Both forms occur naturally and are synthesised through exposure to ultraviolet-B (UVB) rays in sunlight. However, vitamin D2 is synthesised in plants and fungi, whereas vitamin D3 is synthesised in humans and other animals.
Both forms of vitamin D can be used to fortify foods. Howeve`r, research suggests that vitamin D3 is superior for raising vitamin D levels within the body. Thus, vitamin D3 has become the prominent form used in supplements and fortified foods (1).
