Isotonic is a scientifically formulated carbohydrate and electrolyte sports drink for use during exercise. This is a 2:1 fructose mix similar to EnergySource except for a lower carbohydrate concentration and a higher electrolyte content when mixed as directed. In hot conditions, when sweat rates are high, athletes often prefer a “weaker” mixed sports drink with a lower carbohydrate concentration. This can be consumed more easily at higher volumes.

Research on traditional sports drinks suggests that you can only consume 60g carbohydrate per hour. Using Isotonic with 2:1 fructose, you can consume substantially more carbohydrates, up to 90g per hour. That means you get 50% more energy!

Isotonic helps you to sustain your performance during endurance events and keeps you hydrated by enhancing the absorption of water¹. 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 750ml of Isotonic to boost the electrolyte content further.
