Isotonic is a new generation of sports drink. In hot conditions, when sweat rates are high, athletes often prefer a “weaker” mixed sports drink with a lower carbohydrate concentration, which they then consume in higher volumes. Isotonic is the same formulation as EnergySource, except that it has a reduced carbohydrate content when mixed as directed. The carbohydrate in Isotonic is 2:1 fructose (with electrolytes).
Research suggests that you should consume a maximum of 60g carbohydrate per hour from traditional sports drinks. The recommended intake for new generation Isotonic with 2:1 fructose can be substantially higher, at up to 90 gram per hour. The ingredients in Isotonic help sustain performance during tough endurance events and help maintain hydration by enhancing the absorption of water. Leading event organisers and Pro athletes choose Isotonic for hot sweaty conditions.
The electrolyte level in Isotonic should be adequate for most race conditions. However, when sweat rates are very high, we recommend adding a High5 ZERO Neutral tab to every 500ml of Isotonic to boost the electrolyte content further.
