GU2O is now GU BREW Electrolyte - During exercise proper fluid intake is critical. Good hydration helps to prevent overheating and increases your blood flow, transporting vital nutrients and oxygen to your working muscles, which is the most important factor for a good workout. Yet during exercise water is not enough to keep your body properly hydrated. Your body needs electrolytes in the correct ratio to replace the sodium and potassium you are losing through sweat. At the same time, your body needs complex carbohydrates (not sugar) to maintain your blood glucose and muscle glycogen at levels necessary to have a great workout/race from start to finish.

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.
