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 and fructose.

Groundbreaking studies have shown that this exclusive carbohydrate combination delivers up to 50% more energy to working muscles than glucose alone. This muscle fuel can lead to measurable performance benefits. Studies reveal that with C2MAX as the fuel source, 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. Glucose then travels into the small intestine, where it is absorbed into the bloodstream.

At the micro level, glucose molecules have to 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.

C2MAX's 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 may 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 with glucose alone. The more carbohydrates are delivered, the 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: 17% better than water and 8% better than glucose alone. Imagine what you could if your endurance performance was boosted by 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.
