The Second Sign: Unexplained Fatigue and Generalized Weakness.
Feeling tired after a long, active day is completely normal; however, persistent, heavy exhaustion that sleep cannot cure often signals a cellular energy crisis. Magnesium binds with adenosine triphosphate (ATP), the primary energy currency of your cells, to create the biologically active form of energy your body uses.
Without sufficient magnesium, your cells quite literally cannot produce enough power to keep you moving comfortably. Furthermore, this deficiency forces potassium out of your muscle cells, resulting in myasthenia—a condition characterized by profound physical weakness that makes climbing stairs or carrying groceries feel monumental.
