GU Electro Brew Sachets

Advanced Hydration

GU Electrolyte Brew is water's new best friend. The fact is, when you work out you sweat more than just water. So when you drink you gotta have a special Brew with the right amounts of sodium, potassium and carbohydrates to bring your system back into balance. Used consistently, GU Brew will help you perform better and go longer.

Simpler is Better 

No gimmicky additives here. GU Brew is as simple as they come - with just a handful of key ingredients. Complex and simple carbs in optimal balance, vital electrolytes at the proper levels for intense exercise, and all-natural flavors. Simple. This means the product is easy on your stomach and will keep you focused on reaching your goals in training and racing.

Great Flavours / Not Too Sweet 

If you are looking for a sugar bomb, look elsewhere. Loyal GU athletes rave about the lightly sweet taste of our Electrolyte Brew. 


  • Before: Start drinking GU Electrolyte Brew before starting your workout, to maximize hydration levels. We recommend 16-24 oz of GU Electrolyte Brew consumed about an hour before exercise. 
  • During: During exercise, consume 20-30 oz. of GU Electrolyte Brew per hour.
  • After: After finishing your workout continue hydrating with GU Electrolyte Brew, but supplement this with 16-32 oz. of GU Recovery Brew to help your body replenish what was lost during exercise. Combine GU Electrolyte Brew with GU Energy Gels or Roctane Ultra Endurance Gels for the ultimate in sports hydration and fueling. Take one gel 15 minutes before training or competition and then one gel every 30-45 minutes during exercise. Drink GU Electrolyte Brew throughout and when you're finished, complete your workout with GU Recovery Brew. 
  • Note: Because GU Electrolyte Brew contains mostly complex carbohydrates instead of tons of sugar, it does not mix well in icy cold water. Use a little warm or room temperature water to mix it and then top it off with cold water.
