Exercise is a powerful and beneficial form of stress on the body — but it is a stressor nonetheless.

During physical activity, especially endurance training, high-intensity workouts, or explosive movement, the body increases its demand for energy, vitamins, and minerals. These nutrients are required for muscle contraction, nervous system signaling, hormone production, and tissue repair. In addition, minerals such as magnesium, sodium, potassium, and zinc are lost through sweat.

To recover efficiently from exercise, these nutrients must be replenished.
