GlycoDrive Highly Branched Chain Cyclic Dextrin
This unique HBCD was also found to increase post-workout performance, increasing maximal endurance by up to 23 per cent when compared to maltodextrin and sugars. In other research, a different patented HBCD made from potato, rice, and corn was found to be quickly absorbed into the blood stream 18.2 per cent faster than dextrose.

GlycoDrive features Highly branched cyclic dextrins (HBCD) which is made from the starch isolated from barley, corn, potatoes, or rice. HBCDs have low osmolarity and high molecular weights — this unique structure allows for an even faster transit time versus other simple sugars. Unlike waxy starch, GlycoDrive is arranged in linear structures. By changing the structure of the amylopectin through enzymatic processes, this increases the extent of branching and cross-linking and creates unique cyclic structures of branched linked units. Unlike linear chains, the cyclic structures allow for greater access of digestive enzymes that can break apart the bonds faster, passing through the digestive system quicker and providing a sustained release of glucose to the body. In a recent study, research in humans showed that a drink containing a 10-per cent solution of branched-chain cyclic dextrin accelerated stomach emptying much more rapidly versus a drink containing 10-per cent maltodextrin.
This unique patented structure of fractionated barley amylopectin has been shown in university studies to empty the stomach up to 2.3 times faster than maltodextrin and simple sugars. It has also been shown to replenish muscle glycogen 1.7 times faster and is 1.8 times faster at increasing insulin response versus maltodextrin and sugars after intense, exhaustive exercise. Lastly, this unique HBCD was also found to increase post-workout performance, increasing maximal endurance by up to 23 per cent when compared to maltodextrin and sugars. In other research, a different patented HBCD made from potato, rice, and corn was found to be quickly absorbed into the blood stream 18.2 per cent faster than dextrose.
For the new paper in Food Science and Technology Research , the researchers performed three discrete test trials one week apart. For each trial swimmers were randomly assigned to receive either glucose or water or cyclic dextrin. The swimmers then carried out 10 intermittent swimming trials, beginning with 5 minutes of swimming at 75% VO2max, followed by a 3 minute rest, and subsequently an allout effort at 90% VO2max to the point of exhaustion. Trials were conducted in a countercurrent water machine, and so exhaustion was indicated by the swimmer’s forward movement being reversed one full meter by the current.
The studies results indicated that the cyclic dextrin group outperformed swimmers in the other two groups.
“HBCD, a type of maltodextrin with a narrow molecular weight distribution, was proposed to enhance endurance performance in elite athletes, likely by maintaining relatively high blood glucose levels without the negative effects of low-molecular weight carbohydrate,” concluded the researchers.
Commenting on the ingredients potential benefits, they noted that the cyclic dextrin’s very low osmolality and swift gastric emptying time affects water absorption in the small intestine, and hydration during athletic activity.
“Cluster Dextrin HBCD goes to the small intestine rapidly, and there distinguishes itself from glucose supplementation in its maintenance of blood glucose levels, which have been shown to beespecially important during the final stages of an exercise routine,”
