What Is Highly Branched Cyclic Dextrin?
Highly Branched Cyclic Dextrin (HBCD) is a performance carbohydrate created by enzymatically breaking down amylopectin into a high‑molecular‑weight, low‑osmolality cyclic structure. The result is a carb source that:
- Empties from the stomach extremely fast
- Provides smooth, sustained energy
- Doesn’t spike or crash blood sugar like simple sugars
- Doesn’t cause bloating or GI distress
HBCD is the gold standard for intra‑workout carbs in 2026 — especially for lifters, CrossFit athletes, hybrid athletes, and endurance athletes who need fuel without stomach issues. Learn how to use HBCD.

- Low osmolality: Absorbs smoothly without GI stress
- Stable energy curve: No crash mid‑session
- Supports pump + performance: Better glycogen availability
- Pairs well with EAAs, creatine, electrolytes, and pump formulas

When to Use HBCD
- Pre‑workout: 15–20 minutes before training
