What is a 2-in-1 Prebiotic and Postbiotic? Meet ReBiome®
TL;DR: The most well-known postbiotics are butyrate, propionate and acetate. ReBiome® is a patent-pending triacetin – a unique acetate – that works as both a prebiotic and a postbiotic. It delivers bioavailable acetate directly to the colon while also feeding butyrate-producing bacteria. Butyrate-producing bacteria help us digest fiber, so ReBiome® is a critical tool giving formulators a no-bloat way to support gut health, fiber tolerance and next-generation gut health innovation.
In one sentence: ReBiome® helps you digest fibers more easily! ReBiome® is a no-bloat Prebiotic + Postbiotic 2-in-1 that delivers acetate directly to the colon and helps support butyrate-producing bacteria.
Key facts: Triacetin, no-bloat Prebiotic + Postbiotic 2-in-1, delivers bioavailable acetate directly to the colon, supports butyrate-producing bacteria
What is a 2-in-1 prebiotic and postbiotic?
A 2-in-1 prebiotic and postbiotic is an ingredient that works in both categories at the same time. As a prebiotic, it feeds beneficial bacteria. As a postbiotic, it is the end-product the body produces after digesting fiber. Being both a prebiotic and a postbiotic is what makes ReBiome® very different.
ReBiome® delivers bioavailable acetate (a postbiotic) directly to the colon while also helping feed (prebiotic) butyrate-producing bacteria. That dual function is why it fits both the prebiotic and postbiotic conversation, rather than only one.
So ReBiome® is both a prebiotic and a postbiotic?
Yes! ReBiome® is a postbiotic because it delivers acetate, a short-chain fatty acid (SCFA), directly to the colon. It is also a prebiotic because that acetate helps feed butyrate-producing bacteria, which play an important role in fiber digestion and overall gut function.
The combination is what makes ReBiome® a no-bloat prebiotic and postbiotic, rather than a single-lane gut health ingredient.
How does ReBiome® work?
At the center of ReBiome® is acetate.
ReBiome® delivers bioavailable acetate directly to the colon, where it helps support butyrate-producing bacteria. Those bacteria play an important role in fiber digestion, short-chain fatty acid (SCFA) production and the broader foundation of gut health.
This same mechanism connects to fiber tolerance, a healthy gut barrier, leaky gut support and the broader gut-metabolism and gut-brain conversation.
So this is not just another gut health ingredient. It is a more foundational approach to supporting the gut environment, and it’s being used in next-generation formulas.
Why does a 2-in-1 gut health ingredient matter?
Because gut health innovation is moving beyond single-function ingredients. Think of AG1, Huel or Ka’Chava. These are all multi-ingredient formulas catering to overall wellness. ReBiome® is also multi-functional.
Brands are looking for ingredients that do more than check one box, especially in formulas built around digestive wellness, fiber tolerance and leaky gut support. ReBiome® delivers on that shift by bringing more than one gut health function to the table.
How is ReBiome® different from traditional prebiotics or postbiotics?
Traditional prebiotics are usually framed as inputs. They feed beneficial microbes and support fermentation in the gut. Classic examples are inulin, FOS and GOS. The problem with those highly-fermented prebiotics is that they can cause excess gas.
Traditional postbiotics are usually framed as outputs. They deliver beneficial compounds directly.
ReBiome® brings those categories together by delivering acetate directly to the colon while also helping feed butyrate-producing bacteria. That means it does not fit cleanly into only one bucket. It works across both, which is what makes the 2-in-1 framework so important.
Why ReBiome® fits next-generation gut health innovation
ReBiome® was made for the fibermaxxing gut health conversation. We can’t fibermaxx without enough acetate in the colon to feed our butyrate-producing bacteria.
It combines direct acetate delivery, support for butyrate-producing bacteria and a no-bloat Prebiotic + Postbiotic 2-in-1 approach in a way that feels more relevant to where the category is headed. It also fits naturally into fibers, greens, reds, shakes, synbiotics and other gut health products, giving formulators a flexible platform for innovation. ReBiome® is not just patent-pending; it’s the first and only short chain fatty acid (SCFA) to taste good in powder formulas and reach the colon.
For brands trying to create differentiated gut health products, that matters. ReBiome® does not just help them enter the conversation. It gives their product a stronger way to stand apart.
FAQ
What is a 2-in-1 prebiotic and postbiotic?
A 2-in-1 prebiotic and postbiotic is an ingredient that works in both roles. ReBiome® fits that definition because it delivers acetate directly to the colon while also helping feed butyrate-producing bacteria.
Is ReBiome® a prebiotic?
Yes. ReBiome® acts as a prebiotic because the acetate it delivers feeds butyrate-producing bacteria.
Is ReBiome® a postbiotic?
Yes. ReBiome® is also a postbiotic because it delivers acetate, a short-chain fatty acid (SCFA), directly to the colon.
Is ReBiome® just another postbiotic?
No. ReBiome® works as both a postbiotic and a prebiotic, which is why the 2-in-1 framing matters.
How does ReBiome® support butyrate-producing bacteria?
Because ReBiome® delivers acetate to the colon, and acetate is a key food source for butyrate-producing bacteria.
What makes ReBiome® different from other gut health ingredients?
ReBiome® combines direct acetate delivery with prebiotic and postbiotic function, giving brands a more differentiated and no-bloat way to support gut health innovation.
Interested in a no-bloat pre + postbiotic for your next formula?
ReBiome® gives brands a new way to think about gut health by combining direct acetate delivery with support for butyrate-producing bacteria in one no-bloat ingredient.
