"I think you guys [gals ?] are the best. Free shipping on hammer products and super fast service. What's not to like?"

Nancy H.

Dear,

Proline Sports Nutrition & Equipment,

I was shopping for the product below using Google as which time I saw your Google add. This was the first I heard of your company. I went to your site and liked what I saw and proceeded to order the Optygen HP. The order was placed on late Friday afternoon and was delivered (to my surprise) on Saturday. Your service is awesome as well as your price match guarantee. There is no doubt that I will continue to use you in the future, as well as recommend you to others.

Regards,

Brian H
Aurora, IL
 I am very impressed with your customer service.  I was worried about getting my order with a marathon a week and a half out.  Wow, less than 24 hours and my order was sitting on the porch.  That is phenominal service.  I will definately shop with you again.  I have had free shipping take 10 days.  Proline Sports Nutrition is a site I will recommend to my many running/cycling buddies.  Thanks for the great response.  BTW, that info on the Hammer Nutrition products was wonderful!!  It helped me hone in on my nutrition/hydration plan for my marathon.  I printed off the entire 120 pages!  This is my 4th marathon.  I've trained hard, and my Hammer plan I do believe will give me a PR.

Advanced Hydration
GU Electrolyte BrewTM 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 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.
 

Whether you're playing soccer at the park or competing in an Ironman triathlon, you need to replace the fluid you sweat out. If you don't then your body won't function at its best. Even a 2-3% drop in body weight due to dehydration can lead to fatigue and lactic-acid build-up. That can translate into a 7% drop in your performance. If you think that's no big deal, consider this: on average, the difference between the finishing time of the winner in the Tour de France and the last place rider's time is roughly 5%. In an Ironman triathlon, 7% adds around 40 minutes to an elite amateur's time. We thought that would get your attention.

However, the body needs more than plain water to rehydrate. It also needs to restore the electrolytes, sodium and potassium, that it loses through sweat. In addition to these key electrolytes, and to make rehydration even more effective, GU Electrolyte Brew packs a light dose of easily-digestible carbohydrates and a light flavor that keeps your taste buds craving more. That's all it contains because that's all you really need. Anything more would just slow you down.

Electrolytes: Necessary for Optimum Hydration and Muscle Function

There are two major electrolytes in the body: sodium and potassium. You lose them because the body works with its own perfect ratio of water-to-electrolytes1, 2. So when your body turns on the sweat glands in an effort to cool you down, it also expels excess electrolytes to keep that ratio in balance. Conversely, when you drink fluid, you also need to add a proportionate amount of electrolytes back in2, 3. The addition of electrolytes enables your body to keep that new fluid around instead of dumping it in order to restore the water-to-electrolyte balance. These electrolytes also facilitate the neuromuscular system's ability to work effectively so that your muscles keep doing what your brain tells them to do. GU Electrolyte Brew packs 325mg of sodium and 50mg of potassium into one 21 oz. serving.

GU Electrolyte Brew's Carbohydrate Blend: Fuel in the Name of Rehydration

The mix of maltodextrin and fructose found in GU Electrolyte Brew serves a dual role: it supplies working muscles with easily available fuel, and it speeds up the rehydration process by stimulating the absorption of both electrolytes and fluid in the stomach2, 4. 66% of the blend is maltodextrin, a corn-based complex carbohydrate that the body digests faster than simple sugar. The other 33% is comprised of fructose, the principle sugar found in fruit. Research shows that this 2:1 ratio of complex to simple carbohydrates will improve endurance performance by increasing the rates of exogenous carbohydrate absorption.NEW GU Electrolyte Brew uses fructose because the stomach absorbs it in tandem alongside maltodextrin and provides your muscles with as much fresh energy as possible. Fructose also adds just the right amount of sweetness and palatability. Studies have shown that we become highly sensitive to taste after extensive exercise. As a result, what tasted good at the beginning of exercise will, two-plus hours later, taste sickly sweet and become unpalatable. GU Electrolyte Brew, on the other hand, tastes perfect, which means you'll continue to drink it and keep yourself hydrated.

Citric Acid: A Tart and Powerful Energy Helper

Central to the production of energy is the citric acid cycle (Krebs Cycle), which taps citric acid and is responsible for the breakdown of amino acids, glucose, and fatty acids to produce ATP5 (the actual energy molecule that fuels your muscles). GU Electrolyte Brew uses it to speed along the processing of its carbohydrate blend. Citric acid also helps us attain a well-balanced taste flavor profile for GU Electrolyte Brew that keeps you wanting more.

Natural Flavors & Color: The Case for Natural Appeal

Studies show that taste, aroma, and color will most likely determine whether or not you keep drinking. Too much flavor or sweetness?often found in artificially flavored drinks?will cause you to stop hydrating after a while. That's why we invest in all-natural flavor and color. We want you to keep gulping down GU Electrolyte Brew all day and enjoy keeping your fluid level topped off.

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.
