GU Energy Labs

From 1991 until now, athletes around the world have come to the exact same conclusion: GU functions. Our Berkeley-based sports nutrition company started with our original GU Energy Gel, an innovative and more effective system to keep athletes fueled during exercise. Each gel is created in-house under rigorous regulations with emphasis on quality and taste. GU has continued to improve the recipe, incorporating the most recent scientific research into its products. In 2001, GU Electrolyte Brew was started as the ideal hydration companion into GU Energy Gel. Back in 2008 Roctane Ultra Endurance Energy Cable was released, followed by Chomps Energy Chews and GU Recovery Brew in 2009. Every product is formulated to additional GU's assignment: to aid fuel athletes' operation.
