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

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.

GU Electrolyte Brew Tastefully Nude Nutrition Facts

  • Great Taste
    Posted by Sam on 1/27/2014
    I almost just love this stuff because it makes my water taste great. I find that I am much more likely to stay hydrated when I have to stop myself from drinking too much rather than forcing myself to drink. The added benefit of electrolytes and carbs is great as well.
  • Raspberry is the best
    Posted by Carl on 12/24/2013
    I've tried all the flavors and they're all excellent but the raspberry flavor is the best tasting electrolyte water I've ever had. It has a great taste that I crave even when I'm not running or biking.
  • the very best!
    Posted by Bama on 12/17/2013
    This is one of the best recovery tools I've found! Love the flavor
  • Better than competitors tablets
    Posted by Conrad on 11/30/2013
    I worked at a major outdoor retailer and had access to the competitors product for almost free. I still bought GU Electrolyte Brew because of its effectiveness. Also easy on the stomach.
  • So much better than other drinks!!
    Posted by Jimmy on 10/30/2013
    I have tried so many different high electrolyte beverages, and none have matched this product. The taste is the best I have ever had, and it keeps your energy levels higher than any other drink out there!!! Lemon lime rocks!! WAYYY better than gatorade!!
  • Excellent
    Posted by Colby on 9/26/2013
    I tried this product at a sprint triathlon this past weekend and I couldn't believe how great it set me up for the run, and how good I felt afterwards!
  • Tried a few times
    Posted by Brenna on 9/14/2013
    Picked up a handful of free samples of the berry gu brew at a race expo. Have had it as replacement after longer runs. Taste is good! Did not have the heavy/sticky feeling that can be left in the mouth with other sport drinks.
  • Beats others hands down
    Posted by David on 8/16/2013
    After having used the typical sports drinks like Gatoraid during activities this has been an eye opener. When I started reading more on sports nutrition and realized how little electrolytes are actually in the commercial drinks and how much you really lose through sweat this was a no brainer. The extra carbs help replace some of the need for gels and chomps too.
  • Light and delicious
    Posted by Rustin on 8/11/2013
    The sports drink killer, and (possibly) my favorite GU product. A simple electrolyte drink that does everything right without trying too hard. I struggle with sweetness and viscosity, and this is just lightly sweet while having flavor and isn't syrupy. Goes in my water bottle on every long run.
  • positive experience
    Posted by Christopher on 7/13/2013
    I'd have to say that I had a new experience with this electrolyte mix, and I definitely believe it helped, particularly with avoiding muscle cramps which tend to happen to me in the heat when I'm only running on water. The brew had a unique taste, which I am still thinking about, but the performance effects were noticeable.
