#2 — Dextrose
Dextrose is cheap, fast‑absorbing, and widely available — but it spikes insulin and can cause GI distress during intense training.
#3 — Maltodextrin
Maltodextrin mixes easily and fuels training well, but its higher osmolality makes it more likely to cause bloating or stomach sloshing.
Why HBCD Is the Best Workout Carb
- Fast gastric emptying: No sloshing or slowdown
- Low osmolality: Smooth absorption
- High molecular weight: Better fluid dynamics
- Stable blood sugar: No crash mid‑session
- Pairs perfectly with EAAs, creatine, electrolytes
