All Flavors 11/2025

GU Original Sports Nutrition Energy Gel is the energy gel that started it all. In 1993, Dr. Bill Vaughn developed the world’s first energy gel to help his daughter perform better during ultra-marathons, and GU has been helping to propel the world’s most successful extreme athletes to success ever since. GU Energy Gel sustains all forms of athletic activity with a highly compact, portable, and calorie-dense packet that is loaded with carbohydrates for rapid absorption. Branched-chain amino acids limit muscle fiber damage and increase speed of recovery, and extra electrolytes help maintain water balance. Some flavors feature caffeine to increase concentration. While the original formula has been tweaked and evolved over the years, the end result is still the same: GU Energy Gels fuel the best endurance athletes in the world. GU Original Energy Gel comes in a wide variety of good tasting flavors. With the release of the new Raspberry Lemonade Gel, GU is honored to support Rising Hearts and its Running on Native Lands initiative - a program that aims to make it common practice to acknowledge a respectful connection with the land, recognizing that the trails and roads we are privileged to run on are borrowed. Proceeds from the sale of this Gel will support Rising Hearts. Together, all of us can help make the running community and the outdoor places where we play more accessible, safe, supportive, inclusive, and visible.
