Understanding how food intolerance works — and measuring it — is the first step toward feeling better.

Identify Food Triggers

You can measure it

The Problem

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, when there are food sensitivities, the levels of hydrogen and methane can be quite high.

Recognized by health and clinical institutions

A clinical study showed that using the FoodMarble’s first-of-its-kind digestive breath device with its app-led program helped reduce digestive symptoms in just one week, by lowering FODMAP intake and tracking fermentation levels through breath.

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.
