Natusport FUEL+ Dual Sportdrink has been developed for (elite) athletes who want to consume more than 90 grams of carbohydrates per hour. Therefore, FUEL+ products contain relatively more fructose: a glucose-fructose ratio of 1:0.8, compared to 2:1 in our regular sports nutrition.
Why? The absorption of glucose and fructose in the intestine takes place via different transporters. The most important transporter for glucose, the SGLT transporter, becomes saturated at approximately 60 grams of glucose per hour. With a ratio of 2:1, you can add about 30 grams of fructose to this, equivalent to 90 grams of carbohydrates per hour.
Do you want to consume more than 90 grams of carbohydrates per hour? Then a higher amount of fructose can help utilize extra carbohydrates via a different absorption route, via the GLUT5 transporter. At a ratio of 1:0.8, 60 grams of glucose corresponds to 48 grams of fructose: a total of 108 grams of carbohydrates. In short: 2:1 is an excellent ratio for an intake of up to approximately 90 grams of carbohydrates per hour. FUEL+ 1:0.8 was developed for athletes who want to go above that.
If you consume fewer carbohydrates (up to 90 grams per hour), which applies to more than 90% of athletes, choose the standard 2:1 ratio, such as our trusted Isotonic Sports Drink with a glucose-fructose ratio of 2:1. This reduces the risk of stomach upset.
Thanks to the combination of maltodextrin, fructose, and isomaltulose, as well as the flexible mixing ratio, you can use FUEL+ Dual Sportdrink as both an isotonic sports drink and a carbohydrate-rich sports drink for sustained efforts. Additionally, FUEL+ contains the electrolytes sodium, calcium, and potassium, which are lost through sweat during exercise.
Two uses in one sports drink
FUEL+ Dual Sportdrink distinguishes itself by allowing you to use one product in two ways. At a lower dosage, an isotonic sports drink is created that is suitable for training and competitions where fluids, electrolytes, and carbohydrates need to be replenished.
With a higher dosage, FUEL+ transforms into a carbohydrate-rich sports drink that delivers a large amount of carbohydrates per bottle. This makes the drink suitable for long endurance rides, marathons, triathlons, and other sustained efforts where a high carbohydrate intake is desired. This dosage can also be used as part of a carboloading strategy in the run-up to a competition.
With FUEL+, you choose one flexible product that grows with your training goal: from light endurance training to the toughest race.
