Why BICARRB?

and how FLYCARB is fuelling dreams

Decades of research show that sodium bicarbonate can improve exercise performance. The practical challenge is that the high doses needed can cause gastrointestinal distress. BICARRB solves that problem with our innovative flavoured energy mixes, which drastically improves tolerability and makes those doses easier to take.

How Bicarb Works?

How sodium bicarbonate helps buffer muscle acidity

During intense exercise, hydrogen ions (H⁺) accumulate as energy demand rises, contributing to the fall in muscle pH associated with fatigue.
At an effective dose, sodium bicarbonate increases bicarbonate levels in the blood, strengthening the body’s extracellular buffering capacity. This creates a greater gradient for H⁺ to move out of the working muscle, helping limit the drop in pH. The result: a greater ability to sustain high-intensity pace or power for longer.

At rest

When working at low intensity you produce little to no H⁺. Your body holds a stable blood bicarbonate concentration and any H⁺ is easily neutralised by ions already circulating.
