Magnesium is an essential intracellular cation involved in more than 300 enzymatic reactions in the human body. It plays a critical role in neuromuscular transmission, energy metabolism (ATP-dependent reactions), DNA/RNA synthesis, and cardiovascular stability. Despite its importance, subclinical magnesium deficiency is common, particularly in populations with modern dietary patterns. Physiological Role of Magnesium Magnesium is crucial for: Neurological function: Modulates N
