Whether you're engaging in sports, walking, or other activities, or even during daily life such as work or sleep, your body loses water through sweat. Through perspiration, not only water but also electrolytes are lost from the body. Sustain Sports is a beverage that replenishes body fluids, containing four electrolytes: calcium, magnesium, potassium, and sodium. Please dissolve one packet in 500mL of water and drink. It's a convenient stick type for easy carrying.
