Why We Love It

Gu Energy has a loyal following and this Roctane Lemon Berry Energy Drink Mix is just another example of why. Each serving contains 250 calories and carbohydrates in the form of maltodextrin and fructose, which are easily absorbed without causing stomach distress. There’s also sodium to aid with hydration and acid taurine, which improves cardiac output during longer training sessions or races. The dense calorific nature of the drink makes it a great option for longer, more gruelling races where you need more fuel without having to muck around with bars and gels. And the 35mg of caffeine adds a handy boost, too. 

Talk Nerdy To Me

This flavoured mix – all lemons and berries – was formulated specifically for high-intensity and demanding activities like ultra-endurance events. Like a gel, it contains carbohydrates and electrolytes, though this mix goes further by including taurine to help combat heart and skeletal muscle fatigue. It also contains beta-alanine and histidine, which assist the body in dealing with lactic acid during longer efforts.
