Research from in vivo human clinical trials conducted in 2013 by Glico with Cluster Dextrin (Highly Branched Cyclic Dextrin / HBCD) has been accepted for publication in the journal Bioscience, Biotechnology and Biochemistry.
 
The studies showed that during a cycling exercise, 24 practiced adult males experienced significantly less exhaustion after being administered 15 grams of Cluster Dextrin than a similar group given the same amount of maltodextrin. When interviewed they described more energetic performance at both 30 and 60 minute intervals after taking Cluster Dextrin. Additionally, blood was drawn after 30 minutes and examined for blood sugar levels, which tended to be higher in the Cluster Dextrin group. This suggests that it offers a pronounced benefit in promoting endurance and reducing fatigue during exercise.
 
Cluster Dextrin was developed by Ezaki Glico Co., Ltd. and is distributed by Glico Nutrition Co., Ltd. It offers the optimal benefit a carbohydrate-based supplement can provide in the performance of vigorous exercise, according to the company.
 
As an energy source in sports drinks, Cluster Dextrin has low osmotic pressure, and empties swiftly from stomach to small intestine. There it quickly breaks down to enter the bloodstream, thereby sustaining a high blood sugar level.
