Finally something for the bloat
Every probiotic I tried did nothing. This is the first thing actually built for perimenopause bloating, and it shows.
REACT Biome Estrobiotic
from 1.290 ReviewsREACT Biome is the first Estrobiotic, a gummy made for the gut bacteria that help your body recycle estrogen.
In perimenopause, those bacteria begin to fade, and that's a real driver of the bloating so many women feel after 40. It's built to support them, so your gut can settle.
No heavy, full feeling through your day
Made for perimenopause bloating
Two gummies a day. 0g sugar. Gentle dosed

Benefits
We know you've likely tried more than a few things already. The truth is, none of them were built for what actually changed during perimenopause, and this one is. Here's what it looks like once you actually fix the root cause:
- Flat all day, not just the first hour after you wake up.
- Put on a fitted top without turning sideways in the mirror.
- Back out to dinner with friends, instead of canceling again.
- Finally, proof it was never in your head, and never you being dramatic
You've heard promises before. So this time, the risk is on us, not you.
Nothing to lose but the bloat.
The Science
Your estrobolome is the group of gut bacteria that recycle your estrogen (basically, the reason you used to stay flat without trying). For years it just worked, so bloating was never really your problem.
It's the whole gut-estrogen system researchers Plottel and Blaser mapped out in peer-reviewed studies, and it holds up right until perimenopause, when your estrogen drops and those bacteria die off with it. Now you lose it from both sides: your body makes less, and holds onto less of what's left. That double drop is why the bloating feels new, and why your old routine stopped working.
A regular probiotic just adds random strains for general gut health. REACT Biome is built to rebuild your estrobolome, not just pile more on top. It brings back the exact strains that recycle your estrogen and feeds them daily, so the system can get back to work and the bloating can finally settle

THE SCIENCE
Meet the system behind the bloat.
It's called your estrobolome, the gut system that helps recycle your estrogen. As it fades in perimenopause, the bloating follows. Watch the series to see how it works, and how we help it recover.
Chapter 1
The Research says 90% feel less bloated.Here's what that actually feels like.
My jeans fit again
Peri hit and suddenly nothing buttoned by the afternoon. I was living in flowy tops, hiding. Three weeks in I am back in my normal clothes and I almost cried in the fitting room. I did not think this part of me was coming back.
No rough start
No bad first week. Smooth from day one.
That 5pm swell is gone
I would wake up flat and look pregnant by dinner. Classic perimenopause, my doctor said, learn to live with it. I did not want to. The afternoon swelling is so much better now.
Bought it for my wife
My wife was miserable with the bloating and too busy to research anything for herself, so I did it for her. Best thing I have ordered in a long time. She is happier and more comfortable at night, and honestly so am I. Buy it for the woman in your life going through this.
Skeptic here
I roll my eyes at supplements. My sister wore me down. I owe her an apology, because this actually works.
The confidence came back
The bloating was quietly killing my confidence all through perimenopause. I started skipping dinners out. I feel like myself again, and I did not realize how much I had shrunk away until it came back.
Easy
Two gummies in the morning, done. They taste fine and I actually remember them.
Wish I found it sooner
Nobody warned me perimenopause came with this kind of bloating. This is the only thing that explained why it was happening and then did something about it.
Not a quick fix, and that is fine
It built up over a few weeks. By month two I knew it was real. Worth the wait.
Stopped hiding
A whole drawer of clothes I could not wear past noon. Wearing them again. That is all I wanted.
Different from the rest
I have spent a small fortune on gut stuff in my fifties trying to fix this. This is the only one that went after the actual perimenopause cause instead of just throwing more bacteria at me. Five weeks in and it is the only one still in my cabinet.
What the labs found about each ingredient
THE BLOATING-FIGHTER
We made it the anchor of our formula for a reason: it has one of the strongest bloating-relief results ever published in probiotic research.
THE BELLY-FAT TARGETER
Bloating isn't always about gas. The visceral fat that accumulates in midlife adds pressure and discomfort across your whole midsection. This strain was tested to target it directly.
THE BLOATING-SCORE REDUCER
The strain you already trust from yogurt. We just put it at the dose the research actually used.
THE BAD-BACTERIA BLOCKER
Most bacteria-killers wipe out the good with the bad. Cranberry doesn't. It only blocks harmful bacteria from sticking, leaving beneficial ones alone.
THE GROWTH SPARK
A healthy gut isn't just about which bacteria are there. It's about whether they can grow. FOS and Inulin are the plant fibers that let your beneficial bacteria multiply.
YOUR DAILY DELIVERY
The best research-backed formula on the planet only works if you actually take it. That's why we made ours a gummy: people are 60% more likely to stick with it daily.

Questions?
We've got answers
How is this different from the probiotic I already tried?
Most probiotics add random strains for general gut health. React Biome is an estrobiotic, built to rebuild your estrobolome, the gut bacteria that recycle estrogen and fade in perimenopause. That is the part a regular probiotic was never made for, which is likely why it did nothing for your bloating.
How long until I notice something?
This is a protocol, not a quick fix. Most people notice a shift around weeks 4 to 6, with a full reset cycle running about 12 weeks. Taking it daily is what makes it work.
How do I take it?
Two gummies every morning. That is the whole protocol. No powders, no timing rules.
Is it safe with my other supplements or medication?
React Biome is a food-based daily gummy. As with any new supplement, if you take medication or have a health condition, check with your doctor first.
How does the subscription and shipping work?
Choose delivery every 28, 84, or 140 days. Skip, pause, or cancel anytime in two clicks. Orders arrive within 7 to 9 days of shipping.
What if it is not for me?
