"Eat more fiber" might be the most repeated piece of gut health advice there is. It's good advice. But anyone who has added a scoop of fiber to their morning routine knows the catch: more fiber can mean more gas, more bloating and a heavy, uncomfortable afternoon.
The missing piece often isn't the fiber. It's the bacteria that break it down.
What are butyrate-producing bacteria?
Your colon is home to trillions of microbes. One group does an especially important job: butyrate-producing bacteria.
These bacteria ferment the fiber you eat and turn it into butyrate, a short-chain fatty acid. Butyrate is a main source of fuel for the cells that line your colon, and it helps support a healthy gut lining.
In other words, these bacteria sit right at the center of fiber digestion. When they're well supported, your body can get more out of the fiber you already eat.
Why fiber sometimes feels uncomfortable
Many prebiotic fibers, like inulin and chicory root, are high-FODMAP. They ferment quickly in the gut, and that fermentation produces gas. For a lot of people, that shows up as bloating and discomfort.
So the usual fix of adding more fiber can work against the very comfort you were hoping for.
Acetate: the fuel behind the fuel
Butyrate gets most of the attention in gut health conversations. But many butyrate-producing bacteria rely on another short-chain fatty acid to do their work: acetate.
Acetate acts as a food source for these bacteria. When they have enough of it, they're better equipped to ferment fiber and produce butyrate. Supporting acetate supply supports the whole chain.
How ReBiome® works
ReBiome® is a prebiotic + postbiotic ingredient designed to deliver bioavailable acetate directly to the colon, where butyrate-producing bacteria live.
- Prebiotic: the acetate it delivers feeds butyrate-producing bacteria.
- Postbiotic: acetate is itself a short-chain fatty acid, the same kind of compound healthy gut bacteria produce.
- Low-FODMAP: ReBiome® doesn't rely on adding more fast-fermenting fiber, so it's designed to be gentle on digestion.
- Neutral taste and smell: easy to take every day.
Instead of simply adding more fiber and hoping your gut keeps up, ReBiome® supports the bacteria that help digest it.
Who it's a good fit for
ReBiome® makes sense if you:
- Are working more fiber into your diet and want your gut to keep pace
- Have found that some fiber supplements leave you feeling bloated
- Want a simple, daily step for digestive comfort and overall gut health
Where to find ReBiome® at BIGVITA
ReBiome® is a key ingredient in MindBiome+, our 2-in-1 gut-brain formula. It's built to support the gut side of the gut-brain connection, starting with the bacteria that help you digest fiber.
FAQ
What does ReBiome® do?
ReBiome® delivers acetate directly to the colon, where it feeds butyrate-producing bacteria. Those bacteria help ferment fiber and support a healthy gut lining.
Is ReBiome® a prebiotic or a postbiotic?
Both. The acetate it delivers feeds beneficial bacteria (prebiotic), and acetate is itself a short-chain fatty acid (postbiotic).
Is ReBiome® a probiotic?
No. It doesn't contain live bacteria. It supports the beneficial bacteria already in your gut.
Does ReBiome® help with fiber digestion?
Indirectly, yes. It supports butyrate-producing bacteria, and those bacteria help break down fiber.
Is ReBiome® low-FODMAP?
Yes. That's part of what makes it a gentle option for people who find many prebiotic fibers uncomfortable.
