What's In It And What's Not


INDEPENDENTLY CERTIFIED
The Science, Actually
Your gut, explained.
We won't promise to fix your gut. Nobody honestly can. Bloating has lots of causes, and there is no one-size-fits-all solution. So here is the thinking instead: what science believes is going on, and why we built Bloating Bestie the way we did.
Lots of reasons. One common thread.
Stress, alcohol, a high-inflammatory diet of processed foods, antibiotics, your nervous system, travel, environmental toxins. Triggers pile up differently for everyone. What bothers your gut might not bother someone else's.

The Common Thread
What "bloating" usually is
When scientists and gut experts zoom out, they keep coming back to a combo of two things.
Too many of the "bad bacteria"
Your gut is a crowd. When the crowd gets out of balance and the troublemakers take over, gas and discomfort follow. "Bad bacteria" is not even a scientific term, but you know the ones.
The goal: a balanced crowd, where the good guys run the place.
A gut lining with gaps
Your gut lining is one cell thick, and it is supposed to be sealed tight. When little gaps open up, things that should stay in the gut can slip through. That is what people mean by a "leaky" gut.
The goal: a sealed lining, cells shoulder to shoulder.
The Honest Part
Start with the real stuff
The best way to support your gut is still the unsexy list. Work on all of the above first.
Herbs and ingredients do not replace any of that. They support the journey while you do it. Which brings us to the ingredient scientists are most excited about right now.
The Star of the Show
Meet CoreBiome
CoreBiome is a form of butyrate, and butyrate is the food your gut lining eats. Your good bacteria make it when they ferment fiber, and it shows up in butter too. The name literally comes from butyrum, Latin for butter. Yum.
One honest detail: it has a smell. Butyrate comes from fermentation, and butyric acid is literally the compound that gives rancid butter its tang. That smell is how you know it is working.
And since we are showing butter: there is none in the bottle. Bloating Bestie is vegan. No butter, and nothing derived from butter, in the formula. Butyrate is simply a compound that also happens to be found in butter.
So why not just take butyrate? Because most of it doesn't survive the trip. Stomach acid gets to it first, and it never reaches the lower intestine, where it is needed most. That delivery problem is the whole story.
The Delivery Story
The journey
Here is CoreBiome's trip, step by step.
Swallow
You swallow the capsule.
Stomach
Most butyrate doesn't survive the trip. CoreBiome seems to hold up better against stomach acid.
Small intestine
Pancreatic lipases, your digestive enzymes, convert it into butyrate along the way.
Colon
CoreBiome seems to travel further, feeding the good bacteria that help keep the gut happy. In lab models, about half of it arrived.*
Zoom in: the gut lining
Once it arrives, early science is finding a connection: the more butyrate, the healthier and less "leaky" the gut lining tends to look. It is early. Scientists are still discovering. We think it is the most promising thread in gut science right now.
The Formula Logic
Science, meet tradition
We paired that new, promising science with the old wisdom: traditional gut-soothing remedies like ginger, fennel and Oregon grape, the plants herbalists have reached for for centuries.
CoreBiome® (Tributyrin)
In every capsule as your base, surrounded by the traditional remedies in our formula.

*The delivery findings come from a 2025 study (Frontiers in Nutrition) using simulated digestion and laboratory gut models, not a human clinical trial. Butyrate science is new and promising, and how it translates to people is still being discovered.
