I have been learning about vitamin D for years and one of the experts that has taught me the most is Dr John Cannell who founded the Vitamin D Council. In this short interview he talks about the role and power of vitamin D and on its role in optimising the immune system.
A “must watch” 🙂
To test your blood level of your vitamin D check out my Helpful Lab’ Tests page and to check out my recommended vitamin D supplement which is a drop or 2 of vitamin D3 liquid on Amazon click on the picture to the left
For a vitamin D3 capsule the best I could find is Garden of Life Vitamin Code RAW D3
