Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Highly branched cyclic dextrin (HBCD) is a type of carbohydrate used in sports nutrition, particularly among bodybuilders and endurance athletes. Its use is scientifically justified primarily as an intra- or post-workout carbohydrate source due to its unique structural properties. HBCD is produced from amylopectin and has a high molecular weight with low osmolarity, allowing for rapid gastric emptying and quick absorption in the intestines. This results in less gastrointestinal discomfort compared to other carbohydrate sources like maltodextrin or glucose.

Several small-scale studies indicate that HBCD can help rapidly replenish glycogen stores and maintain stable blood glucose during intense exercise, which is beneficial for prolonged or high-intensity workouts. For example, a few randomized, controlled trials have shown improved endurance performance and reduced perceived exertion in athletes consuming HBCD compared to other carbohydrates. Additionally, HBCD is less likely to cause bloating or stomach upset, making it a practical choice for athletes during training or competition.

However, while there is a growing body of research supporting HBCD’s advantages in sports performance and recovery, most studies are limited in scale and often conducted in trained male athletes. There is not yet robust, large-scale evidence directly linking HBCD to increases in muscle mass or strength beyond what would be expected from optimal carbohydrate intake in general. Thus, while use in bodybuilding is scientifically justified for energy and recovery, the evidence base is moderate rather than strong.
