The C2MAX Advantage
PowerBar sports nutrition products feature the muscle-fueling innovation C2MAX, a powerful, dual-source energy blend featuring a 2:1 mixture of glucose to fructose.
C2MAX can lead to measurable performance benefits*. Clinical studies have shown that this exclusive carbohydrate combination delivers up to 50% more energy to working muscles than glucose alone**. Cycling time trial performance improved 8% over glucose alone!* More energy to muscles and improved endurance performance — that's the C2MAX difference.
How does C2MAX deliver more energy?
Until recently, glucose had been thought of as the gold standard for fueling muscles. But glucose moves more slowly through the stomach than C2MAX. It then travels into the small intestine, where it is absorbed into the bloodstream.
At the micro level, glucose molecules must pass through transporters in the digestive tract before they can enter the bloodstream. These transporters process only about 1 gram of carbs per minute. If more glucose is ingested than can be absorbed, it can remain in the gut, causing delayed fluid absorption, GI distress, and, ultimately, reduced performance. It doesn't have to be this way.
The C2MAX dual-source energy blend of glucose and fructose can mean greater endurance*, better performance*, and increased GI comfort during exercise. With C2MAX you'll experience a faster rate of carbs emptying from the stomach and faster delivery to the small intestine for improved absorption into the bloodstream. This efficient delivery process can lessen the chances of GI discomfort while you work out. It might also improve fluid delivery, which is critical to maintaining hydration.
Consuming a mixture of both glucose and fructose takes advantage of two separate micro-level transport systems. Compared to glucose alone, more carbohydrate fuel is delivered to blood and muscles when glucose and fructose are taken together in a 2:1 ratio. With C2MAX you will utilize the carrying capacity of two transport systems instead of just one as with glucose alone. When more carbohydrates are delivered, more energy makes its way to working muscles.
More fuel to muscles with C2MAX
Energy fuel stores last longer and cause less GI distress, better fluid absorption, and significantly increased endurance performance: significantly better than water and 8% better than glucose alone.* Imagine what you could do if your endurance performance were boosted by up to 8%!
So look for PowerBar products formulated with C2MAX. Mix and match them to find an energy combination that meets your performance goals. Get similar results in any form: bar, sports drink, gel, or chew.
