Anything that is tight, irritable, crampy, and stiff—whether it is a body part or even a mood—can be a sign of magnesium deficiency. This critical mineral is actually responsible for over 600 enzyme reactions and is found in all of your tissues—but mainly in your bones, muscles, and brain. You must have it for your cells to make energy, for many different chemical pumps to work, to stabilize membranes, and to help muscles relax. Yet, so many of us are deficient in this important mineral.  In today’s episode of a new series called Health Bites, I discuss why magnesium deficiency is a huge problem, why most of us are deficient, how to identify if you are magnesium deficient, and what to do about it.   This episode is sponsored by ButcherBox and Athletic Greens.
