The role of magnesium in muscle function includes supporting muscle contraction and relaxation processes. It is crucial for energy production, as it aids in the synthesis of ATP (adenosine triphosphate), the primary energy carrier in cells. Magnesium also plays a vital role in regulating calcium levels, which are essential for muscle contraction. Adequate magnesium intake can help mitigate muscle cramps, enhance exercise performance, and promote recovery post-exercise. Foods rich in magnesium include leafy greens, nuts, seeds, and whole grains, making it important for overall muscle health.
