Why it works on bloat
59%
Arrives where bloat begins. 59% of CoreBiome® from a capsule reached the colon intact in a simulated digestive tract.
3 wks
Builds a calmer gut. Three weeks of daily use raised butyrate and enriched beneficial bacteria in a lab model of the human gut.
9
Fast comfort. Nine traditional digestive botanicals, including ginger and fennel, to ease occasional gas and bloating.
550 mg
A full dose. 550 mg of CoreBiome® tributyrin per serving, in the capsule form the research tested.
CoreBiome® delivers butyrate, the fuel your gut lining runs on, past your stomach to where occasional bloating starts, and it does it without the gassy fermentation of fiber-based gut supplements. Figures from Duysburgh et al., Frontiers in Nutrition, 2025 and Jenkins Sánchez et al., Int J Mol Sci, 2026 (laboratory models of the human gut). Benefit statements reflect structure-function claims published by CoreBiome®'s manufacturer, Compound Solutions, Inc. Not a clinical trial of Bloating Bestie. Individual results vary.*

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.
Tap a slice of the wheel
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.
100% Vegan
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.
CoreBiome® (Tributyrin) · Ginger Root · Fennel Seed · Licorice Root (DGL) · Marshmallow Root · Cascara Sagrada · Oregon Grape · Yellow Dock · Cloves
*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.

Why we use it:
The science behind CoreBiome®
Built to beat the bloat from the inside.
Bloating starts in the gut, so that's where Bloating Bestie goes to work. Nine botanicals traditionally used to ease gas and that heavy, puffy feeling, plus CoreBiome® tributyrin , a patented postbiotic that carries butyrate, the fuel your gut lining runs on, past your stomach to where it's needed. Think of it as a fire extinguisher for the flare-ups behind occasional gas, irregularity and that heavy, puffy feeling. Here's what it does, and what the research shows.*
59%
Arrives where bloat begins. 59% of CoreBiome® from a capsule reached the colon intact in a simulated digestive tract.
3 wks
Builds a calmer gut. Three weeks of daily use raised butyrate and enriched beneficial bacteria in a lab model of the human gut.
9
Fast comfort. Nine traditional digestive botanicals, including ginger and fennel, in every serving to ease occasional gas and bloating.
550 mg
A full dose, not a sprinkle. 550 mg of CoreBiome® tributyrin per serving, in the capsule form the research tested.
What CoreBiome® does for your gut
Most gut supplements feed your bacteria and hope for the best. CoreBiome® delivers butyrate, the fuel your gut actually runs on, straight to where it's used.*
Eases occasional gas and bloating
Puts out the flare-ups behind that tight, gassy, heavy-after-dinner feeling, so you feel lighter and more comfortable.
Supports regularity
Butyrate helps keep things moving on schedule, without the urgency or unpredictability of a laxative.
Strengthens your gut barrier
Fuels the cells lining your colon so the barrier that keeps you comfortable stays strong and intact.
Balances your microbiome
Enriches beneficial bacteria and supports a healthier gut environment with consistent daily use.
Promotes a healthy inflammatory response
Supports the calm, balanced gut response that underpins digestive comfort and immune health.
Fuel, not fermentation
Your gut lining prefers butyrate to glucose. CoreBiome® supplies it directly, with none of the gassy fermentation fiber supplements cause.
What the research shows
Peer-reviewed research on tributyrin and butyrate, linked straight to PubMed.
It survives your stomach and gets to work in your gut. In simulations of the human digestive tract, 59% of the CoreBiome® capsule dose reached the colon intact. Three weeks of daily use raised butyrate levels, enriched beneficial bacteria, and had a protective effect on the intestinal barrier.
Lab model of the human gutWhy it matters: plain butyrate breaks down before it reaches the colon. CoreBiome® delivers it where occasional bloating and gas actually start, so it can support a healthier gut environment over time.
Duysburgh C, et al. Frontiers in Nutrition , 2025. Read on PubMed →
It raises butyrate without adding gas. In an ex vivo model using gut microbiota from adults with sensitive digestion, tributyrin-containing formulas increased butyrate while producing milder gas increases than inulin, a common prebiotic fiber.
Lab model, human gut samplesWhy it matters: many gut supplements feed your bacteria with fiber, which ferments and makes you gassier before it makes you better. Butyrate from tributyrin skips that step.
Jenkins Sánchez L, et al. International Journal of Molecular Sciences , 2026. Read on PubMed →
It feeds the gut lining that keeps you comfortable. Butyrate is the key energy source for colonocytes, the cells lining your colon. Maintaining healthy butyrate levels supports colonocyte function, helps maintain the gut barrier, and promotes a healthy microbiome.
ReviewWhy it matters: a well-fed gut lining and a balanced microbiome are the foundation of smoother digestion and fewer bloat-prone days.
Hodgkinson K, et al. Clinical Nutrition , 2022. Read on PubMed →
It supports a strong gut barrier. Butyrate supports intestinal barrier function and mucosal immunity, and directly affects the growth and differentiation of the cells that line the colon.
ReviewWhy it matters: when your gut barrier is doing its job, you digest more comfortably and bounce back faster from a heavy meal.
Fu X, et al. Critical Reviews in Food Science and Nutrition , 2018. Read on PubMed →
It protects your gut lining when life stresses it. In a preclinical model, tributyrin supplementation protected a butyrate-producing microbe and supported small intestinal barrier integrity during a gut-stress challenge.
PreclinicalWhy it matters: big dinners, travel, a glass of wine, a stressful week. Your gut takes hits. Tributyrin helped the gut lining hold the line under pressure.
Siddiqui MT, et al. International Journal of Molecular Sciences , 2024. Read on PubMed →

WHAT TO EXPECT
Every body is different, and results can vary — but here's what most of our besties experience:
How To Use
If you are pregnant, breastfeeding, taking medication, or under medical supervision, consult your doctor before use.
How to take it
How do you take Bloating Bestie?
Three capsules, a glass of water, and about an hour. That's it. Take it after the meal that got you, during your period, or on one of those days when your jeans are suddenly a size too small.
It smells sharp, cheesy, a little like butter left out too long. That means it's working.
Think parmesan, not perfume.
The smell stays in the bottle. Once you swallow the capsule, it's gone.
How it works
Step 1
Take 3 capsules with water. After a meal, or whenever your belly feels tight, heavy, or gassy.
Step 2
Give it the first hour. Ginger, fennel, and CoreBiome® get to work on gas and that puffy, stuffed feeling.
Step 3
Stay consistent. The gut flora support from CoreBiome® builds with regular use, so your bloat-prone days get fewer.
Questions, answered
How fast will I feel it? +
Most women notice comfort within the first hour. Give it the full hour before you decide it isn't working.
How many capsules, and when? +
Three capsules per day as needed, with water. Best after meals or whenever bloating shows up. Don't exceed the recommended intake.
Can I take it every day? +
Yes, as needed, up to three capsules a day. The gut flora support from CoreBiome® builds with consistent use, which is why regulars tend to notice fewer bloaty days over time.
Why does the bottle smell like cheese? +
That's the CoreBiome® tributyrin, a stable form of butyric acid. It's the same compound behind the smell of parmesan and aged butter. Strong scent means the butyrate is intact. It fades the moment you swallow.
Will it send me running to the bathroom? +
It's formulated for comfort, not urgency. Cascara sagrada is traditionally used to support regularity, so if you notice things moving more than you'd like, take fewer capsules.
Does it help with period bloat? +
Bloat is bloat. Ginger and fennel are traditionally used to ease digestive discomfort, whether the cause is a big dinner or Day 24 of your cycle.
What about puffiness and water weight? +
Cascara sagrada and yellow dock are traditionally used to support the body's natural release of excess water, so you feel less swollen and heavy.
Can I take it with probiotics? +
Yes. CoreBiome® is a postbiotic, so it pairs naturally with your probiotic and supports the environment your good bacteria need.
I ate something I know doesn't agree with me. +
Bloating Bestie can support digestion after a meal that sits heavy, but it isn't a hall pass. If you know a food doesn't agree with you, it's still best to skip it.
What's actually in it? +
Nine traditional digestive botanicals in a 1,350 mg blend, including ginger, fennel, marshmallow root, and licorice, paired with 550 mg CoreBiome® tributyrin. One vegetable capsule shell, nothing else. No artificial colors, sweeteners, flavors, or preservatives.
Does it taste like anything? +
No. It's a capsule, so there's no flavor and no aftertaste. The smell stays in the bottle.
I still feel bloated. Now what? +
Digestion is complex, and some bodies take longer. If nothing has shifted after 1 to 2 weeks of consistent use, look at what else is on your plate, literally, and talk to your healthcare provider. Persistent bloating is worth a conversation.
I'm pregnant, breastfeeding, on medication, or under medical care. +
Check with your healthcare provider before starting. Bloating Bestie is for adults only.
How is it tested? +
Third-party tested and validated for purity and quality. Made in the USA in a GMP-certified facility.
