From 1991 until today, athletes all over the world have come to the same conclusion: GU works. Our Berkeley-based sports nutrition company started with our original GU Energy Gel, a revolutionary and more effective method to keep athletes fueled during exercise. Since then, GU has continued to improve the recipe, incorporating the latest scientific research into its products. In 2001, GU Electrolyte Brew (formerly Gu2o) was launched as the perfect hydration companion to GU Energy Gel. 2008 saw the introduction of Roctane Ultra Endurance Energy Gel, followed by Chomps Energy Chews and GU Recovery Brew in 2009. Every product is formulated to further GU’s mission: to help athletes go faster and longer than ever before.
