Magnesium plays a vital role in muscle function by contributing to energy production and muscle contractions. It acts as a cofactor in various enzymatic reactions essential for synthesizing ATP, the body's energy currency. Magnesium helps maintain normal electrolyte balance, ensuring proper muscle function and contraction transmission. Additionally, it is involved in protein synthesis and supports muscle relaxation, preventing cramping and tension. Adequate magnesium levels are crucial for athletes and active individuals, as deficiency can lead to fatigue, weakness, and impaired performance.
