The Problem
In IBS, an overproduction of hydrogen often leads to frequent diarrhea, while excess methane gas typically results in constipation. It’s essential to understand how much gas your body can tolerate without experiencing symptoms.
To better control your symptoms, quantifying hydrogen and methane levels in relation to your food triggers is necessary. This is where AIRE 2 steps in to help master your digestion and take control.
Nearly everyone naturally produces hydrogen in their breath, and many of us have gut microbes that convert it to methane.
However, for IBS, the levels of hydrogen and methane can be quite high.

It has never been easier to test your tolerance to 4 hard-to-digest food components - lactose, fructose, sorbitol, and inulin - using your FoodMarble device and the Food Intolerance Kit.
We’re dedicated to giving you the clarity and confidence you need to manage your IBS.
An independent validation showed that FoodMarble accurately detects lactose malabsorption, with results consistent with clinical methods. This makes FoodMarble a reliable and convenient alternative for diagnosing lactose issues at home.
Measuring hydrogen after eating can help identify patients with chronic gut (GI) symptoms from healthy individuals and may be useful for monitoring patients before, during, and after treatment.
FoodMarble was compared to the top clinical device to evaluate its accuracy in detecting carbohydrate absorption. The comparison showed a perfect match, with 100% diagnostic agreement between the two devices.
Yes, thousands of people with IBS use FoodMarble daily to identify trigger foods and manage their symptoms. The system supports FODMAP testing and long-term tracking.
How does FoodMarble help improve digestion?
FoodMarble identifies how your body responds to different foods by measuring methane and hydrogen levels in your breath, helping you uncover what may be causing bloating, gas, or discomfort.
How long does it take to see results?
You can start identifying patterns in just a few days, but for the most accurate insights, we recommend using the device consistently for a few weeks.
What is the Food Intolerance Kit?
The Food Intolerance Kit contains four sachets of common fermentable carbohydrates: lactose, fructose, sorbitol, and inulin, that are known to be difficult to digest. When used with a FoodMarble device, which measures your fermentation levels, these tests can help you identify which FODMAPs your body may not be tolerating well and in what quantity.
Is FoodMarble clinically validated?
Yes, FoodMarble’s technology has been validated in clinical research settings, including scientific studies on IBS and fermentation patterns. The AIRE 2 uses validated hydrogen and methane sensors, and the testing process aligns with established breath testing protocols.
How often should I use AIRE 2 for IBS management?
Incorporating breath testing into your daily routine can provide valuable insights into your digestion. Aiming for 8–10 breath tests per day is ideal. For long-term IBS relief, we recommend consistent usage over several weeks to establish patterns and identify specific food responses.
