Cluster Dextrin®
A superior carbohydrate source providing fast, sustained energy with minimal gastrointestinal distress.
Also known as: Highly Branched Cyclic Dextrin • HBCD
Overview
Cluster Dextrin®, or Highly Branched Cyclic Dextrin (HBCD), is an advanced carbohydrate source produced from amylopectin. Its unique molecular structure allows for rapid gastric emptying and a sustained release of glucose into the bloodstream. This makes it an ideal carbohydrate for athletes, as it provides steady energy without the insulin spike and potential stomach issues associated with simpler sugars like dextrose or maltodextrin.
Key Benefits
Fast Gastric Emptying
Its high molecular weight and low osmolality allow it to pass through the stomach much faster than other carbohydrates, preventing bloating or discomfort.
Sustained Energy Release
Provides a steady supply of glucose to the muscles without a rapid and sharp increase in insulin levels, avoiding energy crashes.
Improved Performance & Endurance
By providing a readily available and sustained fuel source, it helps maintain high performance levels during prolonged exercise.
Enhanced Hydration
Its low osmotic pressure helps to pull water into the bloodstream along with it, aiding in hydration.
Dosage & How to Take
Dosage depends on the duration and intensity of activity, typically ranging from 25 to 50 grams.
| Purpose | Dose | Notes |
|---|---|---|
| Intra-Workout Fuel | 25-50 grams | Mix with water and sip throughout your training session to maintain energy levels. |
| Pre-Workout Carb Loading | 25 grams | Consume 30 minutes before exercise for readily available energy. |
Best Time to Take
Ideal for use before, during, or even after workouts to replenish glycogen stores.
With or Without Food
Typically consumed on its own mixed with water or an electrolyte drink during training.

Interactions
Scientific Research
Effect of a sports drink based on highly branched cyclic dextrin on cytokine responses to exhaustive endurance exercise
Athletes who consumed HBCD experienced lower levels of stress hormones and pro-inflammatory cytokines compared to those who consumed maltodextrin, suggesting less physiological stress.
