• Dehydration can cramp you up, elevate your heart rate, and cause headaches. Staying hydrated helps make tough workouts feel easier. GU Hydration Drink Tabs provide a boost to your water by supplementing it with electrolytes for improved performance and recovery. Each drink tab contains just 10 calories, in addition to 320 milligrams of sodium and 55 milligrams of potassium to help maintain fluid balance and delay fatigue by replacing electrolytes depleted during exercise.
  • Created for demanding training and competition, GU Roctane Energy Gel stands out from original GU Energy Gel with more sodium, an electrolyte that aids in hydration, and even more branched-chain amino acids (leucine, valine, and isoleucine) that reduce mental fatigue and decrease muscle damage than our original GU Energy Gel. The amino acid beta-alanine helps promote formation of the intramuscular buffer carnosine, while ornithine alpha-ketoglutarate helps promote muscle repair. The 100-calorie packets contain carbohydrates (maltodextrin and fructose) that use non-competing pathways to help maximize carbohydrate absorption and utilization while diminishing stomach distress.
  • Introducing our new 15-Serving GU Energy Gel pouches. We’ve ‘bulked up’ our proven GU Energy Gels into a larger serving size to give you, our athletes, more ways to fuel while training and racing. Loose trash and sticky pockets are hard to avoid when you’re out on the trail or road for hours and hours. That’s why we partnered with Hydrapak to create a custom 5-serving flask and nozzle designed specifically for GU energy gels. Our Flask makes it easy to carry the fuel you need while reducing trail-litter along the way. Less-mess, less-litter, more Energy Gel! After adding your 15 serving gel-pouch to the cart why not check out the 5-serving flask.
  • Created for daily training and competition, GU Energy Gel packs energy-dense calories in a portable packet to help sustain energy demands of any duration or activity.

Sodium, the primary electrolyte lost in sweat, aids in hydration by maintaining water balance. The branched-chain amino acids (leucine, valine, isoleucine) may reduce mental fatigue and decrease muscle damage. This product is made with all vegan ingredients. All GU Energy Gels are gluten free and kosher.
  • We teamed up with our neighbors at Hydrapak to design a customized soft-flask with a high-flow nozzle to make fueling for long efforts more convenient and less sticky. The Flask holds 5-Servings of Energy Gel and includes marks on the back to measure your fuel. Fill it with Energy Gel from our new 15-Serving pouches, fuel with it, and reuse it!

Each bottle includes 50 capsules that are packed with electrolytes (sodium, magnesium, chloride) to aid in hydration by maintaining water balance and plasma volume. Vitamin D is important for calcium absorption and bone health. Vitamin B6 and ginger root may help to combat nausea. Take GU Roctane Electrolyte Capsules before, during, or after exercise to replenish electrolyte levels from any energy-demanding activity resulting in sweat loss.
  • For use before, during, and after activity, our BCAA Capsules help maintain mental clarity, prevent muscle tissue damage, and enhance muscle growth. Each capsule delivers a 4:1:1 ratio of the three BCAAs (leucine, valine, and isoleucine) along with B Vitamins that facilitate muscle tissue recovery and reduce nausea during exercise. Branched-Chain Amino Acids (BCAAs) are the three amino acids responsible for helping to reduce muscle fatigue, speed recovery, and decrease the loss of other amino acids from muscle during exercise. These building blocks of proteins can be found naturally in your diet and are essential to maintaining a positive balance between muscle damage and muscle repair. When: Anytime is a good time to prevent muscle tissue damage. Taking BCAA capsules before, during, and after exercise helps decrease muscle tissue damage as a result of strenuous exercise. This product is made with all vegan ingredients.
