Get started

The Maurten Bicarb System does for bicarbonate what Maurten Gel 100 and Drink Mixes did for carbohydrates — use Hydrogel Technology to encapsulate the bicarb and make high doses tolerable for athletes.

Lactate is not the enemy — it’s a fuel source generated during all-out, intense anaerobic exercise. It’s the increase in acidity during these efforts that overwhelms the muscles and leads to exhaustion.

Large doses of sodium bicarbonate counteract the negative effects of the rising acidity, but there’s always been a catch — stomach issues that cancel out any performance gains.

The Bicarb System cracks the code to deliver the smoothest, most effective bicarb experience ever.

More power to you

The Maurten Bicarb System takes a new approach to unlocking the athletic potential of bicarbonate. The system is made up of three individual components — A, B, and C — the mixing bowl, the hydrogel component, and the bicarbonate component. The components work in harmony to create a bicarbonate experience with enhanced tolerability and duration.

The Bicarb System

Component A — Bowl
The Maurten Bicarb System bowl is designed for accurate and optimal mixing and serving. It is printed with clear instructions, and is sized for single-hand holding and includes a screw-top lid for traveling and storage.

Component B — Hydrogel
History in the making. The hydrogel component draws on our years of extensive hydrogel research to create a specially formulated hydrogel to encapsulate and protect the sodium bicarbonate from stomach acid and allow for easy swallowing without chewing. Each serving contains 40g of carbs to help athletes pre-fuel their race or session.

Component C — Bicarbonate
So minuscule, it’s massive. The bicarbonate component contains groundbreaking mini bicarb tablets designed to offer far greater control. They allow for a slower release of bicarbonate in the intestine — which can both help reduce stomach issues and lengthen the duration of the bicarb effect.

Tried, tested — and triumphed

The Maurten Bicarb System has been developed in collaboration with some of the world's greatest athletes and has been used during some iconic performances like Primož Roglič’s Olympic TT gold and Vuelta-winning heroics, Lotte Kopecky’s epic Strade Bianche victory, and Nils van der Poel’s speed skating 5k & 10k Olympic golds & world record.

Hydrogel and Bicarbonate in perfect harmony

We’ve outdone ourselves. Now you can, too. Get used to the most advanced and harmonious athletic bicarbonate product — ever.

Maurten Bicarb Digital System

Preparation is key — and getting bicarbonate right requires forward thinking. The optimal timeframe for a Bicarb System dose is 1–2 hours after a meal, such as breakfast, and 1.5–2 hours before starting high-intensity training or competition.

Each Maurten Bicarb System includes a QR code to unlock the Bicarb Digital System — created by our in-house nutritional scientists to make it intuitive to plan, prepare, and execute a bicarb session or race. It’s virtually your personal bicarb nutritionist.

Maurten Bicarb system — let’s explain why.

The extremity of anaerobic limits was our starting point. The result is a radical product that shatters those limits.

Let’s go granular

Getting into the details of how bicarb can improve the body’s buffering capacity during lactic-heavy activities requires a science lesson.

So let’s go granular.

High-intensity exercise causes a build-up of hydrogen ions (H+), leading to a drop in muscle pH. It’s a process called *acidosis*. It’s what impacts performance — negatively.

Taking sodium bicarbonate can increase blood bicarbonate and blood pH concentration — which helps move H+ ions out of the muscles. This leads to better control of muscle pH — which is a win-win for power-based sessions and races.
