Vitamin D, also known as calciferol, is popularly referred to as the "sunshine vitamin." Vitamin D can be synthesized in the body with appropriate exposure to the ultra-violet rays of the sun (a process called photosynthesis). This process requires cholesterol, so the resulting fat-soluble vitamin form is known as "cholecalciferol." The synthesized vitamin enters the bloodstream and makes its way to the liver, where it is converted to 25-hydroxycholecalciferol. From there, it goes to the kidneys for the final conversion to 1,25 dihydroxycholecaciferol.

In this final form, as a natural hormone, the body uses vitamin D to help calcium absorption in the intestines, and to release calcium stores from the bones when necessary to maintain calcium blood levels.
