To avoid bonking while exercising, you need a portable source of easily digestible carbohydrates to fuel your muscles. GU Original Energy Gels pack quick, effective, and sustained energy to meet the demands of all types of activity. All Energy Gels are Vegan, Gluten Free, and Kosher. Espresso Love is the ideal flavor for a busy athlete. This flavor will remind you of a bold, rich, dark-roasted cup of joe – so good you might just sip on the gel like it’s a lazy Saturday morning. Plus, with 40mg of caffeine, it’s perfect for those early morning workouts. Love is in the name, and it’s also in the recipe, because here at GU, one of our six core values is love.
