24 citrus flavoured stick packs. Get more from your exercise with Lucozade Sport Hydro Active, the great-tasting, low calorie exercise drink designed to hydrate you better than water. Water replaces the fluid lost during exercise, but when you sweat your body also loses essential electrolytes such as sodium. Lucozade Sport Hydro Active contains sodium to help hydrate the body more effectively. Its also a hypotonic drink, meaning it encourages fast absorption from the stomach into the body, leading to effective fluid replacement. One stick pack has enough powder to make a 500ml drink - simply mix with water.
