• What does my fermentation score mean?

  A fermentation score is an objective reading of the gases (hydrogen and methane) detected in your breath at a given time. It provides a snapshot of the fermentation activity happening in your gut — a natural process driven by your gut microbes as they break down certain carbohydrates or FODMAPs as they're also referred to. Remember, this number isn’t a “good” or “bad” score — it’s simply information to help you better understandPopular

• Your Results: Hydrogen & methane

  Fermentation is a natural and healthy process. It’s something everyone experiences — but for some, the balance tips and those normal processes can start to feel uncomfortable. In your gut, bacteria break down certain carbohydrates through fermentation, producing gases as byproducts — primarily hydrogen and methane. Fermentation plays a vital role in maintaining a balanced gut environment. However, when gas builds up too quickly orPopular

• Combined Fermentation Score Explained

  📊 Understanding Your Fermentation Score Your fermentation score (or F-score) reflects the combined levels of hydrogen and methane gases in your breath. These gases are produced when microbes in your gut ferment food, and together they give us a picture of what’s happening in your digestive system. Both hydrogen and methane contribute to fermentation. Their combined effect is stronger than either one alone — so even if each gas is low individually, the total score may place you in the mPopular

• Getting High Scores? Here’s How to Make Sense of Them

  Understanding Your Fermentation Scores Fermentation is a natural process that happens in the gut — and high levels are not always a bad thing. What matters most is learning how your body responds to different foods. By using your FoodMarble device consistently, you can track fermentation levels over time and see how they change with what you eat. Logging meals in the app helps you connect changes in your scores with specific foods, giving you clearer insights into your unique digestive pSome readers

• Helpful Tips to Understand Your Results

  Look for High Readings When your breath test readings rise into the high range, it can feel concerning — but it doesn’t always mean something is “wrong.” What it suggests is that part of what you ate or drank wasn’t fully digested. Instead, those carbohydrates are being fermented by bacteria in your gut, producing gas that shows up in your breath results. After each test, the app will match your logged meals with your readings.

• Understanding Bloating and Your FoodMarble Results

  Understanding Bloating and Your FoodMarble Results If you’re dealing with bloating, you’re definitely not alone — it’s one of the most common digestive complaints. It can feel frustrating when your symptoms don’t always match your FoodMarble fermentation scores, but this doesn’t mean your device isn’t working. Bloating can have many causes, and fermentation is just one of them. Your AIRE 2 is designed to track fermentation — a powerful piece of the puzzle — but there are other factors at pSome readers

• What do a healthy person's readings look like?

  What scores should I aim for? What do a healthy person's reading look like? We regularly get asked “What f-scores should I aim for?” or "What do a healthy individual's readings look like?" This usually comes from people who are struggling with high fermentation levels and daily gut symptoms. The honest answer? There isn’t a one-size-fits-all target. The Goal Isn’t Zero While low fermentation scores often correlate with fewer symptoms, aiming for zero shouldn't be the goal. ReSome readers

• How Often Can I Test?

  How Often Should You Use AIRE 2 for Breath Testing? It’s natural to want as much data as possible from your AIRE 2, but spacing out your tests is key to getting accurate and reliable results. Why spacing matters Each time you take a breath test, a small amount of moisture is left on the sensor. If you test again too soon, that moisture can temporarily skew your readings. To keep your results accurate, we recommend: Leaving at least one hour between regular day-to-day breath testsFew readers

• Why You Can’t Compare AIRE 2 Readings with SIBO Test Results

  Understanding Your AIRE 2 Readings vs. SIBO Test Results If you’re living with IBS or SIBO, you already know how important it is to understand what’s happening in your gut. AIRE 2 is designed to give you daily insights into your breath hydrogen and methane levels, helping you spot changes and patterns over time. If you’ve previously had a formal SIBO test, you might be curious about how those results compare with your day-to-day AIRE 2 readings. It’s a great question — and here’s what youFew readers

• Inulin Challenge: Late rise in your f-scores

  Concerned about Inulin? If you’ve completed your Inulin Challenge having suspected an issue with this FODMAP, only to observe no real change in your fermentation levels during the 3 hour Challenge —you might be feeling confused or discouraged. Please know you’re not alone. Inulin is a complex FODMAP, and it can sometimes behave in ways that aren’t immediately obvious in your results.

• There's something about Inulin

  What is Inulin? If you’ve ever felt confused about why your digestive symptoms appear hours—or even a full day—after eating, you’re not alone. One possible culprit could be inulin, a type of dietary fiber that belongs to a group of carbohydrates called fructans. Inulin occurs naturally in many foods. It’s especially abundant in garlic, onions, and root vegetables, and it’s also a major component of wheat—meaning it shows up in everyday staples like bread, pasta, and cerealsFew readers

• Lactulose Test Results vs Day to Day Readings

  Why You Can’t Compare Daily Breath Readings to a Lactulose Test Daily breath tests and lactulose challenge tests are two very different tools—and their results aren’t directly comparable. A lactulose test is done while fasting. You drink a synthetic sugar, and your gut’s response is measured in a clean, controlled setting. This helps identify specific fermentation patterns, but it doesn’t reflect how your gut behaves in real life. Daily breath readings, on the other hand, happen dFew readers

• Gastric Transit Time

  Gastric Transit Time Gastric transit time refers to how long it takes for food and drink to move through your digestive system, from the stomach to the intestines and eventually to the colon. This process is unique to each individual and can be influenced by many factors, so the times given below are general guidelines rather than exact rules. Small intestine: Food typically leaves the stomach and enters the small intestine within 1–2 hours. Colon: From there, it usuaFew readers

  FODMAP Stacking: Why Portions Matter Managing a low FODMAP diet can sometimes feel tricky and unrewarding—especially when symptoms appear even though you’ve carefully chosen low FODMAP foods. If this sounds familiar, know that you’re not alone. This is a very common experience, and it doesn’t mean you’re doing anything wrong. What’s happening is something called FODMAP stacking. Even small amounts of FODMAPs from different meals, drinks, and snacks can add up across the day. That’s whyFew readers
