Energy Supplements & Performance Nutrition

It all started in 1993 in a Berkeley, CA kitchen. Our founder, Dr. Bill Vaughan was on a mission to create a better, more easily-digestible fuel for his ultra-runner daughter to race at the iconic Western States 100.

Taking in the right nutritients at the right time allows you to perform your best and feel great doing it. Our Energy Gels contain carbohydrates, electrolytes, and amino acids to keep you going strong.

If it doesn't taste good, athletes won't use it. That's why we continue to add new flavors to our lineup each year. We focus on sweet, sour, bitter, and salty tastes to make sure there's a GU flavor for every craving.

We first created our original gel packets for ultra-trail runners pushing the boundaries of the sport, but over 30 years later, our Energy Gels are just as beneficial for someone hitting the gym after work as they are for world champion triathletes, cyclists, and runners.
