This mineral helps regulate muscle contractions and nerve function, facilitating proper relaxation after exercise. Adequate magnesium levels can alleviate muscle cramps and support overall performance and recovery. Additionally, magnesium contributes to energy production, making it essential for athletes and active individuals aiming for optimal physical performance.
