✅ Test as Often as You Need: You can track your breath readings whenever you like, see how different foods, treatments* and supplements affect your digestion and your SIBO symptoms.

✅ Results in Seconds: We send your methane and hydrogen levels straight to your phone instantly.

✅ Designed for Life with SIBO: Whether you’re just starting treatment*, adjusting your diet, or managing post-treatment care, FoodMarble helps you monitor progress, track symptom triggers, and catch early signs of relapse so you can stay on track with your plan.

For anyone who wants to take an active role in understanding their digestion, especially if you:
- Experience digestive symptoms like bloating, gas, constipation, or diarrhea and want clearer insights into what’s driving them- Live with conditions such as IBS, SIBO, IMO, or other digestive disorders where imbalances in the gut can sometimes play a role- Want to identify your personal food triggers, track changes over time, and support dietary approaches such as the Low FODMAP diet

Whatever you don’t fully digest, your microbes will. In doing so, they’ll produce gases like hydrogen and methane. When these gases build-up, it can cause symptoms like bloating and abdominal pain. FoodMarble helps you find out which foods are leading to excessive amounts of these gases.
AIRE 2 by FoodMarble is the world’s first portable digestive tracker using breath testing technology. Now, by measuring hydrogen and methane gas levels, you can easily understand how certain foods affect your digestion, also allowing you to determine your tolerance thresholds. How much of a particular food is fine for you?

What is SIBO and how does it affect digestion?

SIBO stands for Small Intestinal Bacterial Overgrowth. It occurs when excessive bacteria grow in the small intestine, leading to symptoms like bloating, gas, abdominal pain, diarrhea, or constipation. SIBO can interfere with nutrient absorption and disrupt the gut microbiome.

How does FoodMarble help with SIBO?

FoodMarble’s AIRE 2 device measures hydrogen and methane gas levels in your breath. These gases are produced when bacteria ferment food in your gut. By tracking them on the app after meals or food challenges, you can detect abnormal fermentation patterns: a key indicator of SIBO and better understand which foods trigger symptoms.

How is this different from a traditional SIBO breath test?

Traditional SIBO tests are often done in clinics and only provide a snapshot in time, they are also costly. With FoodMarble, you can test from home, multiple times over the course of your day and week, using real-time technology. This allows for personalized and continuous tracking of your digestive response, which offers deeper insights.

Can I use FoodMarble if I’ve already been diagnosed with SIBO?

Absolutely. If you’ve been diagnosed with SIBO, FoodMarble will help you monitor progress, track symptom triggers, and assess how your digestion changes during treatment or dietary adjustments. It’s also really helpful for post-treatment relapse monitoring and making sure you are on track.

Is FoodMarble clinically validated?

Yes, FoodMarble’s technology has been validated in clinical research settings, including scientific studies on intolerances and fermentation patterns. We use validated hydrogen and methane sensors, and the testing process aligns with established breath testing protocols.

How often should I use AIRE 2 for SIBO tracking?

Thousands of people use the device multiple times daily to manage their SIBO, after meals or during testing protocols. For SIBO tracking, we recommend consistent usage over several weeks to establish patterns and identify specific food responses.
