Energy Source Advanced 2:1 fructose sports drink for general training & racing. Energy Source is a new generation sports drink for use during exercise. It contains a carbohydrate formulation of maltodextrin & fructose in a ratio of 2:1 & key electrolytes. Many of the world’s leading event organisers & Pro athletes choose award-winning Energy Source for success in the toughest endurance events. Research suggests that you should consume a maximum of 60g carbohydrate per hour from traditional sports drinks. The recommended intake for new generation Energy Source with 2:1 fructose can be substantially higher at up to 90grams/ hour. The ingredients in Energy Source help sustain performance during tough endurance events & help maintain hydration by enhancing the absorption of water. The electrolyte level in Energy Source should be adequate for most race conditions. However, when sweat rates are very high, we recommend adding a High 5 ZERO Neutral tab to every 500ml of Energy Source to boost the electrolyte content further.
