There are two kinds of Vitamin D, D2 or Ergocalciferol and D3, or Cholecalciferol . D2 is a synthetic product that is derived from plant precursors. D3 is a natural product that’s produced in all animals upon exposure to sunlight, and can also be made using sheep lanolin. The 50,000 IU cap prescribed by doctors is D2 but most supplements are D3.
