I still don't get why Magnesium levels are not tested; the more reading I do about magnesium. People who can be depleted of Mag are ones who have malabsorption, intestinal issues, use laxatives, use drugs like albuterol, diurtetics, some antibitoitics..etc.
They are pushing for Vit D level to be a certain level but don't check the Mag level. It's weird.
