Each tube contains 12 tablets. 1 tablet mixes with 16 ounces of water. Simply drop a tablet into water, the tablet will fizz (effervesce) for a few seconds and will then be ready to drink. Now you can hydrate and stay hydrated longer with ease.

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 Flavors / 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.

GU Electrolyte Brew Hydrating Instructions
To enjoy GU Electrolyte Brew at its most effective, prepare it just before your workout. If setting out on a multi-hour training adventure, carry GU Electrolyte Brew in powder form and mix it with water while on the go.

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.
