Maglucate is an over-the-counter Magnesium nutritional supplement you can take if you require extra magnesium or if you are not getting enough magnesium in your diet. An insufficient amount of this mineral can lead to undesirable outcomes with your health, including an irregular heartbeat, increased irritability, mental derangement, muscle fatigue/weakness, and an electrolyte imbalance called hypomagnesemia. Your body needs Magnesium for functions like bone mineralization, neuromuscular action and transmission, parathyroid hormone operation, and for proper enzyme function.
