ESSENTIAL INFORMATION
HIGH5 Isotonic Hydration Drink Powder is a bottle-based drink mix for runners, cyclists, triathletes, and other endurance athletes who want carbohydrate plus electrolytes in one format. It suits training sessions, longer rides, and race days where you want fluid and fuel together rather than carrying separate tablets and gels.
Each serving provides 28g of carbohydrate plus sodium, magnesium, potassium, and calcium. Compare it with other hydration powders and sports drink mixes based on carbohydrate per serving, bottle concentration, flavour, and whether you want a lower-calorie hydration option or a drink that also contributes to your fuelling plan.
Mix it according to the serving guidance and adjust intake to your session length, sweat rate, and weather conditions. This is a practical option for athletes who want an easy-to-drink isotonic mix that fits into everyday endurance training and racing.
