Your personal digestive breath tester

You can now run unlimited hydrogen and methane breath tests – all from home

✔️ Unlimited testing: Say goodbye to expensive one-off tests. You can now run as many breath tests as you like. Track your hydrogen and methane levels over time and see how different foods affect your digestion.

✔️  Instant results:  our portable breath tester measures hydrogen and methane quickly and accurately. Results appear on your phone in seconds – no waiting, no guesswork.

✔️  Track symptoms over time: digestive issues can be hard to manage. We help by letting you log your symptoms every day and track changes over time. The more you track, the more you’ll understand what’s going on in your gut.

How does it work?

Our 3-stage program, guides you step by step to better understand your gut and feel your best.

1

Log your food

Enjoy your meal, then log it in the app with a tap. With our food library, you can see the FODMAP content of everything you eat and learn how it may affect your digestion – so you can make smarter choices for your gut.

2

Take breath tests

The more you test, the more insight you’ll get. Take hydrogen and methane breath tests after every meal – and learn what works best for your digestive system.

3

Gain real-time digestive insights

Track your symptoms, review your results, and get personalized guidance on which FODMAPs and foods suit you best – and how much of them you can tolerate. This is what you get: a clear picture of your unique digestive profile.

What makes the difference

Instead of a one-time snapshot, you get the full picture – how your body responds to food, day after day. With this knowledge, you can make confident choices, feel more in control, and finally start to understand what your gut truly needs.

Thousands are using FoodMarble to feel better

“If you’re dealing with unexplained or undiagnosed digestive issues, I highly recommend giving the AIRE a try. It’s been essential for my journey toward understanding and managing my symptoms better, and with the AIRE 2 now able to test for methane as well, it’s an even more powerful tool for people facing issues like SIBO.”

“Great device. I like the instant and repeated feedback unlike a traditional breath test. Other info such as food eaten, etc can be recorded as well to see how that might affect a person's methane and hydrogen levels.”

“The FoodMarble AIRE 2 was the best investment for me since I am toughing out my SIBO/IMO-path...I don't have to pay for other breathtests any more. I can do it with the foodMarble AIRE 2. As I am very critical I first did a good home lab test at the same time as the breath test with the AIRE 2. The result was the same, same curves, just a different scale.”

FoodMarble AIRE 2 FAQs

We have microbes living in every part of our body. This is totally normal and healthy. As we move through the digestive tract, the number of microbes at each site increases. We have the most microbes in our large intestine. However, sometimes excess microbes can end up in our small intestine. When this happens, a condition called small intestinal bacterial overgrowth (SIBO) can occur. Those with SIBO often have symptoms of abdominal pain, bloating, nausea, belching, diarrhea and constipation. Some people with SIBO may produce more hydrogen, while others may produce more methane. It is important to speak with your doctor if you suspect you have SIBO. If you’ve received a diagnosis of SIBO from a doctor, this device could be helpful for tracking the levels of fermentation in your small intestine.

Visceral hypersensitivity (sensitivity to distension of the GI tract) and altered motility (constipation or diarrhea) are characteristics of IBS. About 40% of those with IBS tend to have more diarrhea. About one third of those with IBS are generally more constipated. The remainder switch between constipation and diarrhea. Those with IBS-C tend to have more methane producing microbes than those with IBS-D. Measuring both gases can help you gain clarity around your symptoms, in particular constipation.

Yes, it’s possible for us to share your results securely with your doctor, as long as we get your consent. Assuming your doctor is comfortable to proceed, just send an email to clinical@foodmarble.com with contact details for your doctor and we’ll take it from there.

By making breath testing a part of your day, you can discover a lot about your gut. If you manage to take between 8-10 breath tests each day, you are doing an excellent job. Here’s a good approach to daily breath testing:

– Take a baseline breath test once you wake up, after brushing your teeth and before eating food.

– Wait until one hour after your breakfast, then test hourly until your lunch.

– After lunch, wait an hour, then test hourly until your next meal and so on until you reach a maximum of 10 tests.

AIRE 2 measures both hydrogen and methane gases in your breath. These gases are produced during fermentation in the gut when certain foods aren’t fully digested. By measuring both, AIRE 2 provides more accurate, real-time insights into how your body responds to different foods, helping you better understand your digestive health.

It is important to speak with your doctor if you suspect you have SIBO. If you’ve received a diagnosis of SIBO from a doctor, this device could be helpful for tracking the levels of fermentation in your small intestine.
