Bicarb System

Is the Bicarb System for me?

Bicarbonate can be used in training and competition for sports that require intermittent or constant intensity near or above the anaerobic threshold, such as cycling, middle-distance running, rowing, swimming, team sports, and combat sports.

It can also be used in threshold (interval) training for all types of endurance sports.

However, the use of bicarbonate during prolonged steady-state endurance events such as marathons or long-distance triathlons is still an area of research.

The mixing instructions for the Maurten Bicarb System can be found on the box, or in the digital planner. The powder of component B is mixed with water in component A to create a hydrogel. The bicarbonate mini tablets (Component C) are added to the hydrogel and stirred in before consuming.

If you are a Bicarb user, please refer to the more detailed mixing instructions on the box or in the Digital System to ensure an optimal Bicarb experience.

No. The Bicarb System is specifically designed with precise serving sizes to ensure optimal efficacy. Component C (mini tablets) and Component B (hydrogel powder) are formulated to work in synergy with their designated ratios. Altering the serving size by splitting a larger portion into two smaller servings disrupts this balance and may compromise both the effectiveness of the system and — ultimately — athlete performance.

No. The hydrogel component of the Bicarb System has been specially designed for its dual functionality:

1. Ingestion: Mini tablets, when dispersed in the hydrogel, should be kept suspended. The consistency of the hydrogel makes it easier to swallow the mini tablets.

2. Protecting against premature release of bicarbonate in the stomach by contact with gastric acid: Although other products may be called “gel” or “hydrogel”, this does not mean that they can replace the Bicarb System hydrogel.

For optimal results, always follow the recommended pairing included in the Maurten Bicarb System.

Maurten does not recommend the use of Bicarb for those younger than 18 years old. This product is specifically designed for elite athletes, and its high sodium content makes it unsuitable for children. If you have more questions, reach out to us here: Contact form


Large doses of sodium bicarbonate balance the rising acidity that overwhelms the muscles during all-out, intense anaerobic efforts. Sodium bicarbonate has a long history of use in sports.

The Maurten Bicarb System has received Informed Sport certification, guaranteeing a product free from substances prohibited by WADA (World Anti-Doping Agency), and manufactured to high-quality standards. Every batch is tested before it’s released to market.

The Maurten Bicarb System is different from bicarb solutions and bicarb capsules, the two traditional forms of bicarbonate. The Maurten Bicarb System is a combination of bicarb mini tablets and a hydrogel.

The hydrogel helps ingesting the mini tablets and protect from dissolving prematurely in the stomach. Because of their small size, mini tablets are not caught in the stomach as capsules do, resulting in a more controlled transfer from the stomach to the intestine, where they gradually disintegrate and the sodium bicarbonate is dissolved and absorbed.

The intake of sodium may lead to water retention and weight gain.

Daily or weekly high intake of sodium may lead to an increase in blood pressure. Individuals with a previous history of high blood pressure should consult with a healthcare professional before using the product.

Total sodium of each dose:

Bicarb System 15 (15g of Sodium Bicarbonate) = 4100mg

Bicarb System 19 (19g of Sodium Bicarbonate) = 5200mg

Bicarb System 22 (22g of Sodium Bicarbonate) = 6000mg

Bicarb System 25 (25g of Sodium Bicarbonate) = 6800 mg

Component B contains a total of 39.2 grams of carbohydrate, of which 14.4 grams are sugars, composed of maltodextrin and fructose - this is the same across all bicarb doses.

The Bicarb System should be ingested 1.5–2 hours before intense exercise - warming-up can be started before this. The Bicarb Digital System has been 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.

No.

The carbohydrate mix is designed for use together with water that does not have a high mineral content. The amount of water should be about 200 ml, with the possibility to take a little less or more to obtain the viscosity that suits you the best.

For water with high mineral content/high hardness, a reduced water volume may be used.

Component A and B can be prepared the day before. It is then recommended to keep it overnight at refrigerator temperature. Component C should only be added immediately before consuming.

The mini tablets should always be ingested alongside the hydrogel.

If the digital system states that you have the incorrect dose based on you weight you have provided, please follow our returns policy.

No, each of the three types of products are different in terms of the hydrogel.

Yes. The Maurten Bicarb system is suitable for vegans and vegetarians.

We recommend not to exceed 2–3 doses per week. On days when you use the Maurten Bicarb System, there is no need for taking sodium supplements.
