It's ironic to live in the Valley of the Sun and learn you are vitamin D deficient when the sun is our best source for it.
In this ABC15 Health Insider conversation, Dr. Shad Marvasti is explaining that our hotter climate contributes to people spending more time inside than out.

Watch our full conversation in the player above to learn your options for improving your levels — with the help of your doctor — using foods rich in vitamin D like mushrooms, fatty fish, and fortified grains as well supplements.
