Cluster Dextrin®: The King Of All Carb Supplements Designed To Fuel Endurance Performance

What Is Cluster Dextrin®?

Cluster Dextrin Carb For Endurance

 

 

 

 

 

 

 

 

 

Cluster Dextrin® is a low glycemic, highly branched cyclic dextrin (HBCD), which has a high molecular weight and ultra-low osmolality. These properties of HBCD makes it highly soluble and promotes fast gastric emptying, virtually eliminating any gastric distress often associated with less advanced carbohydrates.

ClusterDextrin® also maintains a slow release, offering the ideal interaction between carbohydrate breakdown and the normal release of free fatty acids. The result is a superior carbohydrate that delivers smooth, constant energy and replenishes muscle glycogen stores without spiking blood sugar levels.

What Does The Research Say About Cluster Dextrin®?

Cluster Dextrin® is research proven to enhance endurance performance, promote fast gastric emptying times, and lower markers for stress hormones after exhaustive exercise compared to other carbohydrate sources. No other carbohydrate source can demonstrate clinical data like this.

Cluster Dextrin Carb For Runners

  • In a 2013 human clinical trial of Cluster Dextrin®, 24 adult male athletes showed that during cycling exercise, the group administered 15 grams of Cluster Dextrin performed better than those who took the same amount of a maltodextrin.
  • An additional research study conducted in 2015 found swimmers who supplemented with HBCD before doing intervals at 75–90% VO2 max were able to improve time to exhaustion by 70% compared to when they supplemented with either water or glucose.
  • Hiroshi et al. (2004) discovered subjects who consumed a sports drink based on 10% HBCD during bicycle exercise experienced few gastrointestinal disorders and consequently could continue the exercise comfortably with little fatigue compared to the groups who consumed a glucose-based sports drink.
  • Lastly, a 2014 study conducted by Suzuki et al. found that triathletes who consumed HBCD before a race had a reduced stress hormone response and lower urinary cytokine levels compared to when they supplemented with glucose. This suggests that HBCD lowers the inflammatory response of exercise, which in turn leads to increases in performance and less time spent recovering.

The Bottom Line On Cluster Dextrin®

Cluster Dextrin Carb For Cyclists

Cluster Dextrin® has the same molecular weight as maltodextrin but with more “branching.” Branching refers to short chains of poly- and oligosaccharides that “branch” out from the main starch molecule. This enhances digestion. Research on Cluster Dextrin® has demonstrated that it has faster gastric emptying time, reducing the potential for upset stomachs, and improves endurance performance. This is why it is the primary carbohydrate in our SustainElite sports drink.
