The mineral magnesium is crucial for nerve function and muscle contraction. It plays a vital role in muscle relaxation, energy production, and maintaining electrolyte balance. Adequate magnesium levels contribute to efficient nerve signaling, which is essential during physical activity. A deficiency in magnesium can lead to muscle cramps, fatigue, and increased risk of injury. Including magnesium-rich foods such as leafy greens, nuts, seeds, and whole grains in one’s diet can help maintain optimal levels for overall health and performance.
