Description

Unlike many conventional sports drinks, Roctane uses maltodextrin and fructose to maximise carbohydrate absorption through non-competing pathways. This results in steady energy without digestive discomfort, allowing athletes to stay focused and fuelled. Each serving also provides 1,900mg of Branched-Chain Amino Acids (BCAAs), which aid in muscle repair, reduce fatigue, and promote faster recovery during and after exercise.

The formula is further enhanced with beta-alanine, which supports carnosine production to delay muscle fatigue, and taurine, known for supporting heart function and cardiac output in demanding sessions. To maintain hydration and electrolyte balance, Roctane includes sodium, the primary electrolyte lost through sweat, keeping your muscles firing and your body properly hydrated.

Lightly flavoured and easy to mix, Roctane is ideal for long runs, rides, and races where consistent energy and hydration are key. It's performance-focused nutrition, designed to help you go further, faster, and stronger.

How does it work

GU Roctane Energy Drink Mix is designed around the needs of endurance athletes, combining fast-absorbing carbs, recovery-supporting amino acids, and performance-enhancing ingredients like beta-alanine and taurine. Its dual-source carbs (maltodextrin and fructose) speed up energy delivery and reduce gastrointestinal issues common in long events.

The drink mix also supports muscle endurance and cardiovascular output with beta-alanine and taurine, while BCAAs work to reduce fatigue and improve recovery. Sodium plays a vital role in keeping fluid levels stable and supporting muscle contraction, making Roctane a comprehensive fuel solution for extended, high-effort sessions.
