Magnesium is an essential mineral needed by every cell in the body. As an electrolyte, it’s important for regulating fluid balance, nerve and muscle function, blood pH, and neurotransmission. It also serves as a cofactor for hundreds of different enzymes, giving it a role over 300 metabolic reactions—including pathways for cell signaling, energy production, protein synthesis, nucleic acid synthesis, and ion transport. Magnesium also has important structural functions in cells and bone tissue. Co
