Magnesium is a vital electrolyte integral to over 300 enzymatic reactions essential for normal physiological functions. These include ATP metabolism, nucleic acid synthesis, muscle contraction, and nerve function. Its crucial role in cellular energy production and stabilization of cellular processes underscores the importance of maintaining appropriate magnesium levels. Despite its significance, magnesium imbalance, particularly hypermagnesemia, is relatively rare but can have severe clinical implications, especially in critically ill patients.
