Listen- Do you smell something?
Your gut microbiome speaks in gases.
Let’s listen.
(no, not that kind of gas. well, yes, a lot of that kind of gas, but not that kind of listening. grow up. or don’t. we haven’t)We’re building the first at‑home device to reliably measure three key markers of gut microbiome activity — in real time.
Your breath carries signals from deep inside your gut. These signals come from three gases produced by microbial communities as they break down food, compete for resources, and interact with your digestive environment. They aren’t produced anywhere else in the body, which makes them a uniquely direct window into your gut microbial activity. Each gas reflects a different microbial guild- together they form a dynamic outline of your gut ecosystem.
Hydrogen (H2)
Produced by microbial fermentation of carbohydrates. Often linked to the activity of disruptor fauna like Escherichia and Klebsiella. Shifts in hydrogen reveal how quickly microbes are breaking down foods and how active certain fermenting species are.Methane (CH4)
Generated by methanogenic archaea. Methane production correlates with gut transit speed and reflects organisms such as Methanobrevibacter smithii.Hydrogen sulfide (H2S)
Produced by sulfate‑reducing bacteria like Desulfovibrio and Fusobacterium. H2S levels indicate sulfur‑metabolizing pathways and microbial activity tied to mucosal interactions.
Together, these gases form a dynamic signature of what your microbiome is doing — not last month, not last year, but right now.
You can’t manage what you can’t measure.
We’re building the yardstick for you. We’re engineering a device that gives reliable, repeatable results. With it, we can build a map of your gut microbiome and how it functions- a map you can use to help navigate to your goals- and probably to help set a few, too.
