Vitamin D is not a true vitamin. It's a hormone that organisms have been photosynthesizing for over 750 million years as a result of exposure to sunlight.

Vitamin D:

  1. enables your bones and teeth to grow properly
  2. helps your body absorb calcium and phosphorous

Vitamin D is found in:

  • oily fish
  • cod liver oil
  • mushrooms exposed to sunlight

Vitamin D is produced in the body when it is exposed to sunlight.

Vitamin D3, also known as cholecalciferol is the natural human form of vitamin D made in the skin when cholesterol reacts with sunlight.It doesn't have significant biological activity, so it must be metabolized first by the liver and then by the kidneys to be converted into fully-active, hormonal form of Vitamin D known as calcitrol.

Vitamin D3 is now being studied for treatment of certain cancers.
