Each taster pack contains a complete, weight-specific serving split into two sachets. The Energy Mix supports absorption and stomach comfort, followed by the Bicarb Mix which delivers the active bicarbonate dose. This two-step approach makes BICARRB far easier to tolerate than traditional bicarbonate loading, while still delivering proven performance support during high-intensity efforts.

BICARRB is trusted by runners, cyclists, triathletes, HYROX and hybrid athletes looking to push harder for longer when intensity is high. It helps delay fatigue, reduce muscle burn, and improve repeat sprint and sustained power output, all while remaining legal, WADA compliant, and suitable for tested athletes.

During high-intensity exercise, your muscles produce hydrogen ions as a by-product of energy production. This increase in acidity is a key contributor to fatigue and the familiar burning sensation in the muscles. Sodium bicarbonate acts as a buffer, helping neutralise these ions and maintain a more optimal muscle pH.

By improving acid buffering, BICARRB can increase time to exhaustion, support repeated high-power efforts, and help athletes sustain performance when intensity is high. Research also suggests bicarbonate can aid post-exercise recovery by reducing residual acidity, allowing athletes to train and compete more consistently.
