Highly branched cyclic dextrin (HBCD) is a form of carbohydrate commonly used in sports nutrition, particularly among athletes and individuals seeking to support muscle performance and recovery. Scientific evidence suggests that HBCD is effective in supporting the muscles body system primarily due to its unique structural properties. HBCD is produced by enzymatically rearranging amylopectin, resulting in a high molecular weight and low osmolality carbohydrate. These characteristics enable it to be rapidly emptied from the stomach and absorbed efficiently, which is advantageous during and after strenuous exercise when quick carbohydrate replenishment is desired.

Several studies have compared HBCD with other carbohydrate sources such as maltodextrin or glucose. Research indicates that HBCD can provide a steady release of glucose into the bloodstream without causing significant gastrointestinal distress, making it suitable for consumption during prolonged or intense exercise. Some clinical trials have demonstrated performance benefits, such as improved endurance and reduced perception of fatigue, when HBCD is consumed during exercise. Additionally, replenishing muscle glycogen stores post-exercise is essential for muscle recovery, and HBCD has been shown to be effective for this purpose.

However, while the existing scientific evidence is promising, most studies are small and focused on acute performance markers. There is a need for larger, long-term studies to fully establish the magnitude of HBCD’s benefits for muscle function and recovery. Overall, the use of HBCD to support the muscles body system is supported by a moderate level of scientific evidence.
