The carbohydrate matrix that forms the protective hydrogel. When mixed with water and xanthan gum, it creates a thick gel that physically encases the sodium bicarbonate — slowing its contact with stomach acid and dramatically reducing GI distress. Also provides fast-acting carbs for pre-session fueling.
19g
Sodium Bicarbonate
The active performance ingredient. At 0.27–0.3g per kg of body weight, it raises your blood's buffering capacity before exercise — allowing your muscles to sustain harder efforts for longer before acidity forces you to back off. Studied in sports science since the 1980s and endorsed by the ISSN.
12g
Fructose
Paired with maltodextrin at a 2:1 ratio to unlock dual-transporter carbohydrate absorption — the same mechanism used by Maurten and FLYCARB. This allows your gut to absorb more carbohydrate per hour than glucose alone, and produces a lower blood sugar spike compared to sucrose or glucose-only formulas.
1g
Freeze-Dried Mango
Real freeze-dried mango, ground into a fine powder. Makes a high dose of bicarb gel genuinely palatable — you need to drink the full 60g in one go, and this makes that possible. Contributes a small amount of natural sugar (~0.8g) and trace fiber. No artificial flavoring, no extracts.
0.6g
Xanthan Gum
The hydrogel agent. When mixed with water, xanthan gum thickens the liquid into a viscous gel within minutes. This gel physically surrounds the sodium bicarbonate particles, protecting them from dissolving in stomach acid and enabling controlled release in the small intestine — the same mechanism Maurten's system uses.
0.2g
Silicon Dioxide
Food-grade silica — a tiny amount that keeps the dry powder blend free-flowing in the sachet. Without it, the mix can clump over time, especially in humid conditions. It's the same excipient used in Maurten's formula and is found in most dry supplement powders. Completely inert, passes through the body unchanged.
What's not in it.
✗
Artificial flavors
Flavor comes from real freeze-dried mango only.
✗
Artificial colors
No dyes, no colorants. The powder is off-white naturally.
✗
Preservatives
Dry powder is shelf-stable without them. None needed.
✗
Caffeine
Pure bicarb buffering — no stimulants added.
✗
Magnesium stearate
A tablet lubricant Maurten uses for their pellets. Not needed in our gel format.
✗
Modified starch
Maurten uses this for extra gel thickness. Xanthan gum handles that for us.
✗
Gluten
All six ingredients are naturally gluten-free.
✗
Animal products
Every ingredient is plant-derived or mineral. Fully vegan.
