If you have been advised a series of vitamins and are wondering about their effects, here are a few facts you need to know about vitamin D. It is one of the more complex vitamins that are needed by the human body in order to grow and develop. Vitamin D is actually available in two forms, cholecalciferol and Ergocalciferol, better known as vitamin D3 and vitamin D2.

First things first. Vitamin D can be found in 2 forms. Vitamin D2 is manufactured by plants or fungus. You would include it through fortified foods such as juices, milk or cereals. However, vitamin D3 is formed when the body synthesizes sunlight on its surface.
