Hi Five Zero tablets produce a clean tasting and highly refreshing sports drink with zero calories. The tabs contain light natural flavours with no artificial colours or preservatives. With electrolytes and magnesium. Zero hydrates fast, so it can be used as part of an anti-cramp strategy. Simply drop a tab into your re-usable sports bottle and watch it rapidly dissolve. The 20 tab tube makes up to 15 litres of drink, so itâ€™s great value for money. With minimal packaging, Zero is environmentally friendly and easy to keep with you. The easy- break tabs mean that you can choose your ideal drink strength. Zero is great for anyone who wants to stay hydrated and with a low calorie intake. Itâ€™s suitable for a wide range of sports activities such as: football, rugby, biking, martial arts, motor racing, running, triathlon, swimming, hiking, aerobics and racquet sports. With a light non-sweet taste, Zero can be consumed for long periods when working in hot environments such the mining and oil industry, fire fighting and the military.
