GU Roctane Energy Drink Review

Since 1991, GU Energy Labs has been manufacturing products designed for endurance athletes involved in activities that require their body to produce as much energy as possible. From marathon running to ironman training, GU Energy Labs employs a revolutionary and more effective way to ensure these athletes remain sufficiently fuelled during exercise. The company is proud to only use the highest quality ingredients that are blended at the proper temperature and speed to make certain every product is of the utmost quality and consistency.

GU Roctane Ultra Endurance Energy Drink is packed with the much needed carbohydrates athletes need to maintain their endurance over long distances or periods of time. It includes these critical carbs as well as electrolytes and amino acids to ensure that endurance athletes can compete at optimal levels.

GU Roctane Energy Drink Key Ingredients

  • Beta-Alanine – an amino acid that improves performance and muscle buffering capacity during intense workout sessions, reducing the effects of lactic acid in the muscles.
  • Taurine – a key amino acid needed to maintain heart and muscle performance during long periods of exercise.

  • Electrolytes – including potassium and sodium, that are required for proper hydration and muscle function.
  • Caffeine (not included in Grape flavour) - acts to stimulate the central nervous system, as well as decrease the perception of pain. It also delays the feeling of fatigue and improves overall performance.
  • BCAA’s - Leucine, valine and isoleucine are BCAA’s that decrease muscle damage, improve recovery time, and delay the onset of fatigue.
