How to get your vitamin D

 “Humans make thousands of units of vitamin D within minutes of whole body exposure to sunlight. From what we know of nature, it is unlikely such a system evolved by chance.”

– John Cannell MD, Executive Director, Vitamin D Council.

There are only two ways to receive vitamin D in the amounts necessary for proper health: Ultraviolet B (UVB) exposure and vitamin D supplementation. Diet should not be considered a satisfactory source of vitamin D. The few foods which do contain vitamin D, contain too little to be of any noticeable benefit. 12

  • Ultraviolet B (UVB) exposure – Sun exposure should be your method of choice for getting vitamin D. Learn about the factors which influence vitamin D production from sunlight and how to make the most of your time in the sun.
  • Vitamin D supplementation – Information supplementing with vitamin D3. Learn why the amount recommended by the US government is not enough to receive the full health benefits of vitamin D.
