Vitamin D is not one, but many chemicals. The natural type is created in the skin from a universally present form of cholesterol, 7-dehydrocholesterol. Sunlight's is the key. Ultraviolet B (UVB) energy converts the precursor to vitamin D3. Contrast that to most dietary supplements that are manufactured by exposing a plant sterol to ultraviolet energy, that produces vitamin D2. Because their function is nearly identical, D2 and D3 are lumped together and simply called vitamin D.
