This episode was previously recorded while we were on the road, but we could not post it due to a lack of internet connection.  We are releasing it today as a follow-up to our conversation with Dr McGetrick.  Nutritional deficiency is a real thing, even in first world countries.  Magnesium, the second most common nutritional deficiency in the U.S., gives us an opportunity to look at how this happens and the problems it causes.
