FoodMarble is a health tech company that sells breath test devices and an app that may help people with irritable bowel syndrome (IBS) and other digestive issues identify their food intolerances. Research suggests these devices are accurate.
The bacteria and other microorganisms living in a person’s digestive tract are called the microbiome.
A person’s microbiome is unique to them, which may account for why some people respond to certain foods differently from others. In recent years, researchers have looked more into the microbiome as a potential avenue to treat chronic illness and help with various other health conditions. For example, some evidence
FoodMarble developed two devices and an app that people can use to monitor their meals and how their microbiome reacts to different foods. The concept behind the devices revolves around the principle that certain foods interact with a person’s unique microbiome differently and can account for higher levels of gas, bloating, discomfort, and other symptoms in some people.
This article looks into the FoodMarble brand, including its products and reputation. It also provides information on alternative services and products and advice on when to contact a doctor about digestive problems.

FoodMarble is a health tech company that sells breath tests for digestive health.
FoodMarble devices measure how much gas the bacteria in a person’s gut release during digestion using a breath sample. The FoodMarble app records this as “fermentation.” These gas levels can indicate how quickly or slowly certain sugars pass through a person’s digestive system, which can suggest how effectively their body digests them.
A person can use this information to determine which foods they may have an intolerance to. They can also monitor their meals, stress levels, and sleep symptoms.
FoodMarble sells two breath test devices, the AIRE and the AIRE 2. Both devices provide readings on how a person’s microbiome responds to different foods.
After breathing into the device, users can then use the FoodMarble app to log the foods they ate, any reactions they experienced, and how they felt following the meal or snack.
Combined with the reading from the AIRE product, a person can use this information to develop an understanding of which foods cause excessive gas in their digestive tract. They can then tailor their diet around foods that do not cause this reaction.
FoodMarble also sells a Food Intolerance Kit, a 6-week plan that tests a person’s intolerance to four food components that can be hard to digest: lactose, fructose, inulin, and sorbitol.
Below is an overview of the pros and cons of each FoodMarble product and service as stated by the company.

The devices do not require a prescription, and the company states that it ships its products throughout the United States, Canada, Australia, and Europe.
According to the FoodMarble website, its products are suitable for people living with:
- lactose and dairy intolerance
FoodMarble warns that its devices do not accurately measure or test for celiac disease.
The company writes that its devices are suitable for children, but an adult must supervise them. Its products are not suitable for infants.
A person should work with a doctor to receive a diagnosis for and treat any digestive symptoms they are experiencing. Tests such as those from FoodMarble should not replace regular care or advice from a doctor.
FoodMarble provides step-by-step instructions detailing how to use its devices and food intolerance test on its website.
A person can download the FoodMarble app from Google Play for Android devices or the App Store for iOS. They will then need to open an account with FoodMarble to use the app.
Using the AIRE or AIRE 2
Once set up with the app, a person can follow these steps to use the AIRE or AIRE 2:
- Charge and power on the device.
- Allow it to warm up so it can get an accurate reading.
- Select “Breath” on the home screen.
- Log food, stress levels, sleep, and any symptoms into the app.
The breath test involves three steps. A person should:
- Hold their breath for 3 seconds.
- Create a seal around the device with their mouth.
- Gently blow through the device for 5 seconds.
The device will shut down after the test is complete. The app will then begin tracking and showing patterns in the foods a person eats. This may provide a person with insight into which foods they respond to and those they do not.
A person needs to check their breath up to 10 times a day at the following times:
- once when they get up
- an hour after breakfast and then hourly up until lunch
- an hour after lunch and then hourly up until dinner
They will need to repeat the pattern until they have a total of ten readings for the day.
Using the Food Intolerance Test
To use the Food Intolerance Test, a person must order a kit on the company website and download the FoodMarble app.
The kit follows a 6-week plan divided into three stages: baseline, reset, and discovery.
The baseline stage involves building up a picture of a person’s breath scores, FODMAP intake, the symptoms they experience, and their stress and sleep levels. The app will then compare data from this stage with data from the discovery stage.
For some people, foods containing FODMAP substances can cause digestive symptoms.
In the Reset stage, people cut out FODMAP foods from their diet. This stage lasts 1 week, during which a person continues to log their meals, breath scores, symptoms, stress, and sleep data.
The Discovery stage involves testing lactose, fructose, sorbitol, and inulin. A person will test one of these components per week and continue to log their usual data during this final stage of testing.
The FoodMarble app provides a library of recipes a person can follow throughout the 6-week testing period.
FoodMarble’s devices and app may help people with IBS, SIBO, or other digestive issues figure out trigger foods that cause bloating and gas.
There is a limited amount of clinical data on the effectiveness of the devices. However, some research has produced positive results.
According to a
There is debate among researchers as to whether reducing FODMAP foods help people with conditions such as IBS. Some studies suggest that low FODMAP diets can cause a reduction in beneficial bacteria in the gut. Others suggest they
The authors of the 2019 study note that low FODMAP diets are not sustainable.
A person should share their AIRE results with a doctor to get informed analysis, interpretation, and advice on managing or treating their digestive symptoms.

Is FoodMarble good?
FoodMarble may be helpful for some people in determining which foods cause them excessive gas, bloating, and abdominal cramping. For the tests to provide the most accurate results, they require a person to take some time to test their levels, log the food they eat each day, and record their reactions.
How much does FoodMarble cost?
FoodMarble offers two devices at different prices. The AIRE costs $179, and the AIRE 2 costs $249. The accompanying app is free and does not require a subscription or contain in-app purchases.

What does FoodMarble do?
The FoodMarble AIRE measures hydrogen levels in the breath. The AIRE 2 measures hydrogen and methane levels. These measurements can help show which foods the bacteria in a person’s gut microbiome react to, potentially causing symptoms such as bloating, abdominal pain, and excessive gas. A person can use data the AIRE devices collect to make changes to their diet or lifestyle if necessary to help reduce these symptoms. A person should always talk with a doctor to interpret their results.
How do you use FoodMarble?
FoodMarble uses a combination of a handheld breathalyzer and an app. A person will need to test their breath using the device up to 10 times a day and record the foods they eat and how they respond to the food. The app then helps track and develop recommendations on foods a person may need to avoid to help reduce uncomfortable digestive symptoms.
FoodMarble is a health testing company that sells two breath testing devices: a food intolerance test kit and an app. These devices may be useful for people who experience digestive discomfort after eating and those who live with irritable bowel syndrome, small intestinal bacterial overgrowth, and other digestive conditions.
The device measures the levels of gas a person’s body releases during digestion. This may help people determine which foods they are sensitive to and allow them to reduce symptoms such as excess gas, bloating, and discomfort.
A person should always consult a doctor if they experience symptoms of a digestive condition.
