Maurten Bicarb System

$70.00 USD

Maurten Bicarb System is built for high-intensity performance, where acidity becomes the limiter and power starts to fade. By pairing sodium bicarbonate with Maurten’s Hydrogel Technology, it delivers a meaningful bicarb dose in a format designed to be more usable and more tolerable than traditional sodium bicarbonate loading. Best suited to efforts near or above threshold, from TTs and punchy races to hard interval days and repeated anaerobic work.

IS THE BICARB SYSTEM RIGHT FOR YOU?

Maurten’s Bicarb System is for riders targeting hard efforts near or above anaerobic threshold– crits, cyclocross, punchy road races, and any effort above your lactate threshold. This is not an everyday endurance fuel. It is a specific tool for sessions and events where buffering capacity can meaningfully affect repeatability and power output, and where that extra punchy effort could be the difference between winning and blowing up.

KEY FEATURES

Blood Buffering Mechanism

Maurten Bicarb System is built around sodium bicarbonate’s role as an extracellular buffer. During hard exercise, hydrogen ions accumulate and lower muscle pH, making it harder to sustain power. Increasing bicarbonate availability helps buffer that acidity and can extend performance in efforts around threshold and above. Bicarb System is for high-intensity training and racing – repeated hard efforts, short-duration racing, and sessions where acidity becomes a limiter.

Hydrogel Technology

The key differentiator of this and traditional bicarbonate protocols is delivery. Maurten’s Hydrogel Technology is designed to improve tolerance and control how the bicarbonate is consumed and absorbed. The mini-tablet format and hydrogel system help protect the bicarbonate from dissolving too early in the stomach and enable a more controlled transfer through the gut. That matters because bicarbonate has long been effective in theory but inconsistent in practice due to GI distress. Maurten’s Bicarb System solves that.

System Sizing

Maurten Bicarb System is offered in five serving sizes: 12, 15, 19, 22, and 25. The system of you is determined by two things: body weight and previous experience using bicarbonate. Maurten’s sizing guide separates novice and experienced users before recommending a dose, which makes this a protocol rather than a generic pre-race supplement. The takeaway is simple: choose the system that matches your weight and tolerance history–doing so ensures proper dosing, and optimal performance.

BICARB SYSTEM COMPONENTS

COMPONENT A

The bowl is the setup piece. Maurten designed it for accurate mixing and serving, with printed instructions, a one-hand-friendly shape, and a screw-top lid for storage or travel. In practice, it’s there to make the prep precise, clean, and repeatable.

COMPONENT B

This is the delivery system. Maurten’s hydrogel is formulated to encapsulate and protect the sodium bicarbonate from stomach acid, so it goes down easier and doesn’t need chewing. Each serving also includes 40g of carbohydrate, so it doubles as a bit of pre-fuel before a hard session or race.

COMPONENT C

This is the working part. Maurten uses mini bicarbonate tablets designed for more controlled delivery, with a slower release in the intestine. According to Maurten, that slower release can help reduce stomach issues and extend the duration of the bicarbonate effect. The whole point is to help buffer the rise in acidity that builds during high-intensity work, where effort starts to get expensive.

Maurten Bicarb System FAQS

Maurten Bicarb System is a hydrogel-based bicarbonate fuel designed for high-intensity exercise. It combines sodium bicarbonate with Maurten’s Hydrogel Technology to help buffer exercise-induced acidity in a format designed to be more tolerable than traditional bicarbonate loading.

It works by increasing bicarbonate availability to help buffer hydrogen ions that build up during hard efforts. The hydrogel system helps control delivery and protect the bicarbonate from dissolving too early in the stomach.

It is designed to support performance during efforts where acidity becomes a limiter — typically high-intensity sessions and races around or above threshold. That includes hard interval days, TTs, repeated surges, and short-duration race efforts.

Choose your system based on body weight and prior bicarbonate experience. Maurten offers five sizes — 12, 15, 19, 22, and 25 — and uses a guide that distinguishes between novice and experienced users before recommending the right system.

1–2 hours after a meal and 1.5–2 hours before a race, event, or high-intensity session. It should be part of a deliberate pre-session fueling plan, not an improvised last-minute addition.

The active ingredient is sodium bicarbonate, but the product is more than a spoonful of baking soda. The system adds hydrogel-assisted delivery, mini-tablet dosing, structured sizing, and a clear pre-session protocol designed to improve usability and tolerance.

WHY MAURTEN

Maurten has a clear lane in performance nutrition: make effective fueling strategies more usable in the real world. With Bicarb System, that means taking a well-established ergogenic aid and applying the same hydrogel logic that made its carbohydrate products so influential. The result is a more structured, more tolerable bicarbonate protocol for high-intensity efforts, rather than a traditional approach built around guesswork.
