CARBOHYDRATE-THE INSIDE STORY
Carbohydrate is the premium-grade fuel your muscles use to race fast and far. Unfortunately your body can only store a relatively small amount of carbohydrate. In events lasting more than ninety minutes, you will deplete your body’s store of carbohydrate reducing your best performance. To race fast and far, you need to provide your body with additional carbohydrate during your race. The best way to do this is to use a drink or gel.
Drink and gel manufacturers formulate their products from a range of commonly available carbohydrates. These include maltodextrin, dextrose, glucose polymers etc. Although each manufacturer chooses a different blend of carbohydrates in their product, all drinks and gels are digested and absorbed in the same way: the majority of the carbohydrate they contain rapidly breaks down during digestion to glucose, which is then absorbed through the wall of the intestine before being carried away by the bloodstream to the working muscles..
THERE IS A LIMIT TO HOW MUCH CARBOHYDRATE YOUR BODY CAN ABSORB EACH HOUR
Before the glucose provided by your drink or gel can get into your blood stream, it must first pass through the wall of your intestine. It does this using the glucose-transporters known as SGLT1 and GLUT2. These are like revolving doors, allowing one molecule of glucose through at a time. Although there are vast numbers of transporters, they still work relatively slowly. They can only cope with moving a maximum of 60g of glucose per hour through your intestine wall.

VERY HIGH FRUCTOSE IS THE KEY
Super Carbs easily exceeds the 60g
absorption limit for carbohydrate. Even standard High5 Super Carbs drinks have been shown by researchers to deliver 90g of carbohydrate per hour. This is possible because they contains a very high level of fructose (up to 40%).
Fructose is the carbohydrate found in fruit and it’s unique. Fructose passes through the wall of the intestine using a totally separate transporter system called GLUT5, it doesn’t use the glucose-transporters at all. Fructose is the only carbohydrate that is absorbed in this way. In effect it uses a second set of revolving doors to gain entry.
Super Carbs drinks are formulated to take advantage of both the fructose and glucose absorption pathways - it uses both sets of revolving doors. It provides just the right amount of carbohydrate to saturate the glucose-transporter system and a large amount of fructose to make maximum use of the fructosetransporter pathway. The result is 60g of glucose and 30g of fructose passing into the blood stream each hour. That's a total of 90g of carbohydrate to fuel your best race performance, or 50% more than traditional drink and gel formulations can deliver. But that’s not all. High5 EnergySource Plus (with Super Carbs) is now enhanced with a moderate dose of caffeine, which offers two additional benefits..
THE 1ST BENEFIT OF CAFFEINE
Caffeine has been shown to speed up the action of the glucose-transporters by as much as 25%. EnergySource Plus is now able to deliver 110g (440kcal) of carbohydrate per hour..

bottleneck. You are able to swallow a very large amount of carbohydrate and your muscles would be able to burn much more than 60g per hour, if you could get it into your blood stream.
In fact the glucose-transporters are the major bottleneck when it comes to getting the maximum amount of carbohydrate into your body. This is where current drink and gel formulations simply fail to deliver.
The 60g absorption limit is not affected by how quickly your brand of drink or gel empties from your stomach. Nor is it affected by how fit or how big you are, or if your drink is isotonic or not. The 60g limit applies to every athlete and it’s bad news for endurance racers, who must get as much carbohydrate on-board as they can.
If it were possible to bypass the bottleneck caused by the glucosetransporters, then you would be able to get more carbohydrate into your body each hour. Super Carbs is the first drink in the world designed to do just that.
