Electrolytes, such as sodium, potassium, and magnesium, play a crucial role in physical performance. They help regulate hydration, muscle function, and nerve signaling, all of which are vital for effective exercise. During physical activity, electrolytes are lost through sweat, and replenishing them is essential for maintaining optimal performance, preventing cramps, and avoiding fatigue. Additionally, balanced electrolyte levels support recovery and can enhance overall endurance during prolonged workouts, making them an essential component of athletic nutrition.
