The First Sign: Muscle Twitches, Spasms, and Cramps.
Experiencing a sudden, sharp pain in your calf or foot—commonly known as a charley horse—often points directly to a magnesium shortfall. In healthy muscle tissue, calcium triggers muscle fibers to contract, while magnesium steps in to help those fibers relax.
When you lack adequate magnesium, calcium floods your muscle cells unchecked, keeping the fibers in a state of hyper-contraction. For older adults, these painful spasms frequently strike during the night, severely disrupting sleep patterns and leaving muscles feeling bruised or exhausted the following day.
