GU Brew

New GU Brew is about electrolytes first, then carbohydrates. But carbs are key to endurance nutrition so we take them seriously. We use a 50:50 ratio of fructose (simple) and maltodextrin (complex) carbs because carbs in this combination increase the amount of energy available to muscles.

GU Brew is naturally flavored with an ultralight taste profile for great drinkability prized by hardworking athletes.


Box of 24 single serve stick packs - $32.40
Canister (24 servings) - $18.00

*Flavor is temporarily unavailable when unable to choose flavor.

GU Brew focuses more on hydration and less on carbohydrate delivery, offering 70 calories per serving. This 3% carbohydrate solution provides added flexibility to the athlete. Mix it as instructed for rapid absorption or combine with your favorite GU/Roctane gel for increased energy density during longer workout days. For athletes looking for a more energy dense carbohydrate solution, try Roctane Energy Drink.

Hydration before exercise:

To ensure proper pre-exercise hydration, consume approximately 16-24 oz. (470-720 ml) of GU Electrolyte Brew within an hour of the start of your workout.

Rehydration during exercise:

Fluid replacement should approximate sweat and urine losses during exercise and is dependent on many environmental factors. Generally, it is required to consume 7-10 oz. of fluids (200-300 ml) every 10 to 20 minutes during exercise, but specific individual recommendations are based on exercise duration, sport dynamics, sweat rates, and individual tolerance.

Rehydration after exercise:

Rehydration after exercise should aim to correct fluid loss accumulated during exercise. Depending on one’s exercise duration and intensity, replace the electrolyte losses from sweat by consuming GU Brew and jump start protein syntheses with the help of GU Recovery Brew.


What happened to Brew Electrolyte? Can I still purchase it?

Brew retains all of the attributes of the previous formula with a slight formulation tweak to improve performance.

Why GU Brew when original GU is already great?

They’re two different products, designed to work in tandem. Electrolyte Brew keeps you hydrated by replenishing the electrolytes your body sweats out during exercise. GU provides your body with energy to exercise and to maintain your effort during long workouts and events. The two products serve different, but equally important, functions. Most of our elite athletes carry both GU energy gels and Electrolyte Brew with them during training and racing.

GU Brew tastes lighter than some of the other sports drinks I’ve tried. Does this mean it’s less effective?

No! Many sports drinks on the market are full of sugary sweeteners and other unnecessary additives. Large amounts of sugar in your drink can lead to bloating in your belly. With GU Brew, we give you only the stuff you need to stay hydrated and none of the extra fluff.

How much should I drink each hour?

Approximately 24-32 ounces will do it. On hot days, you may even want to drink twice as much.

Will GU Brew recharge my body faster than GU energy gel?

Try it, every person will react differently. However, we don’t suggest you forgo eating GU or Roctane altogether. These gels pack valuable amino acid formulas that reduce fatigue and sharpen your mental state. Our sports drink was designed to work in tandem with the regular intake of GU Energy Gel and Roctane.

How long does GU Brew, once mixed into a beverage, remain stable? Does it need to be refrigerated?

Ideally GU Brew should be mixed just prior to exercise or competition. If you know you’re going to need more than one bottle of GU Brew, we suggest you carry it along in powder form and mix it with water when needed.

Should I dilute GU Brew?

No! GU Brew was specifically formulated to deliver the energy and electrolytes you need to perform your best, hour after hour.

Is it affected by heat if warmed up for use on cold days?

It is not affected by heat, but some people like the taste of hot GU Brew while others don’t.

Are there any foods or drinks to avoid while using GU Brew that would stunt or block the effectiveness of the ingredients?

All food, when taken simultaneously with GU gels or GU Brew, will diminish their powers. GU gels and GU Brew are designed to be used on an empty stomach (at least 3 hours after the last meal). This way you can keep fueling even when you’re pushing yourself to the max without worrying about slowing down to digest food.

Is GU Brew Kosher?

GU Energy Gel, Roctane, GU Brew, and GU Recovery Brew are all certified Kosher. Chomps are not.

  • Perfect pre-workout

    Nearly every hydration drink is far too sugary to me. I was continually finding myself in need of cutting the beverage in half with more water. GU Brew is the first that I find to be a fantastic balance. As a marathoner, hydration is increasingly important. I can drink it before and during runs with no issues at all. Highly recommend trying the Blueberry Pomegranate, especially on a hot day.
  • easy to use

    I loved this product , so easy to carry out and use, and the flaver it's very good , I recomend
  • Great Stuff!
    Posted by Eric R. on 10/19/2014
    Tastes great, with a slightly sweet taste. For those who cannot stand the thought of drinking another sip of an overly sugarery sports drink, this is a great alternative to keep you going strong.
  • Switched and not going back

    Over the years I have tried many sports drinks for energy and replacing lost sodium. I am an endurance athlete who sweats ALOT. I was introduced to Gu Brew at this year's Levi's Gran Fondo. First I thought the rest stop volunteers were making it too weak because of the light taste. Turns out I was wrong. This stuff doesn't overpower you with flavor but delivers electrolytes and some carbs. It didn't upset my stomach in the 90 degree heat and I never felt bloated like I do with some other sports drinks. Bought two flavors today and I' m tossing the remaining Accelerade I have in the pantry.
  • Solid effects with taste

    The consistant great taste that GU gives wins again with this electrolyte drink. I feel the hydration effects and increase performance when I use GU Brew
  • Wow!
    Posted by Brett on 8/2/2014
    I can't stand the popular brands of sports drinks b/c they are way too sweet. GU has really nailed it here, the perfect combination of flavor and sweetness. A must drink for every run / bike I do. Love it!!!
  • Goes down easy

    Finally switched over to Gu Brew and wish I had done earlier. Very light tasting, no sugary aftertaste, and perfect no matter what the weather. Wish I had changed from Gatorade a lot sooner.
  • A very good hydration powder
    Posted by PAUL on 7/1/2014
    I wanted a cheaper and more green alternative to buying bottles from the grocery store. I started training to run half marathons and decided water was not going to be enough. Gu Brew has been a great supplement to my training regime. The powder mixes well with water and tastes fantastic when cold. The price can't be beat and there are great flavors to choose from. I highly recommend this product.
  • Good flavor, not too sweet
    Posted by Patricia on 6/16/2014
    These won't gross you out with the sensation that you're guzzling sugar. Perfect refreshment for working out in the heat.
  • Love it!
    Posted by Emily on 6/15/2014
    I've discovered drinking calories and supplementing with gel is the right combo to fuel me for ultra marathons. This is a great product that is easy on the stomach and even tastes great 100 miles later.
