With FoodMarble, you can test from home - as often as you need - without the expense or delays of one-off tests.
That’s right, unlimited testing.

Who is this for?

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

Why does breath testing matter?

Whatever you don't fully digest, your gut bacteria will. In doing so, they produce gases like hydrogen and methane. When these gases build up, it can cause symptoms like bloating and discomfort. FoodMarble helps you find out which foods tend to lead to higher levels of these gases for you.
AIRE 2 is the world's first portable digestive tracker using breath testing technology. By measuring hydrogen and methane gas levels, you can start to understand how certain foods affect your digestion — and get a sense of your own tolerance thresholds.

Frequently Asked Questions

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 tracks your hydrogen and methane breath gas levels, giving you visibility into daily patterns and how they shift in response to different foods and habits.

How is this different from a one-off breath test?

Traditional breath 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?

Yes. Many people use FoodMarble to track their own patterns day-to-day while working with a healthcare provider on their overall approach.

Is FoodMarble clinically validated?

Yes - FoodMarble's technology is backed by more than 10 years of research, including studies comparing it against reference lab devices.

How often should I use AIRE 2 if I have SIBO?

As often as you like. Many people test multiple times a day to build a clearer picture of their patterns.
