The Gut-Hormone Connection: What Women Need to Know
Most women have never heard of the estrobolome, the gut bacteria that help determine how your body processes estrogen. Ten questions give you a clear read on yours, and what it means for your hormones, cycle, energy, and weight.

What to do with this score.
Educational only, and not a treatment plan. Talk to your healthcare provider before changing medication or supplements.
One capsule a day, aimed at the estrobolome itself.
Hormone Balance Probiotic ES1 is formulated to support the bacteria that help the body clear estrogen rather than recirculate it, supporting beta-glucuronidase balance, gut motility, and microbiome diversity together.
- Clinically studied strains, one capsule daily
- Supports healthy estrogen metabolism
- Designed for daily, ongoing support
Consistent daily support can help.
Hormone Balance Probiotic ES1
The daily probiotic that supports clearing estrogen: the exact process your score flagged.
How Hormone Balance Probiotic ES1 is designed to work.
- Week 1Daily dosing begins. The clinically studied strains start to establish in the gut, the groundwork for everything after.
- Week 4Designed to support beta-glucuronidase balance and regularity, so estrogen is more likely to clear than recirculate.
- Week 8Formulated to support microbiome diversity, the stage many women say they notice most across their cycle.
- Week 12Matches the length of the clinical trial behind these strains, the window they were studied over.

What is the estrobolome, and why has no one told you about it?
The estrobolome is a collection of gut bacteria that specialize in one critical job: metabolizing estrogen. The liver processes and packages excess estrogen for elimination, but before it leaves the body, it passes through the gut, where estrobolome bacteria help determine its fate.
When the estrobolome is balanced, these bacteria help ensure estrogen is properly eliminated. When it’s imbalanced, an enzyme called beta-glucuronidase can reactivate estrogen that was already packaged for excretion and send it back into circulation. Over time this can mean more estrogen recirculating than the body intended, a researched pattern in the science of estrogen balance.
The research is accelerating. In 2026, researchers reported that modern industrialized lifestyles may be changing how the gut microbiome processes estrogen, increasing estrogen recycling in ways researchers are actively studying in relation to women’s hormonal health. The estrobolome is no longer niche science. It’s one of the most important pieces of the hormonal health picture that most doctors aren’t discussing yet.
“The gut microbiome plays a central role in regulating hormones that affect menstrual cycles, fertility, mood, and symptoms across the reproductive years.”
Patterns women often connect to the estrobolome
An imbalanced estrobolome rarely announces itself as a gut problem. The experiences women report are often hormonal. Many women who report three or more of the following find the estrobolome worth understanding:
These experiences aren’t random, and they’re not inevitable. Researchers increasingly connect them to the gut-hormone axis, a system you can support.
These experiences have many possible causes. This is educational only and is meant to prompt a conversation with your healthcare provider, not to attribute any symptom to the estrobolome specifically.
How the gut helps regulate estrogen
The connection between gut health and hormones works through a process called enterohepatic circulation, a feedback loop between the liver and digestive system.
The liver processes excess estrogen and packages it for elimination, sending it to the gut via bile. In a balanced estrobolome, this estrogen is eliminated through stool. But when gut bacteria are imbalanced, whether through antibiotics, a low-fiber diet, chronic stress, or hormonal contraceptive use, beta-glucuronidase activity can increase, “unwrap” the packaged estrogen, and release it back into the bloodstream, where it circulates again.
The more imbalanced the estrobolome, the more times estrogen may recirculate before it’s eliminated. Research connects recirculating estrogen to mood, skin, sleep, metabolism, and inflammation. The gut-hormone connection isn’t a secondary factor in women’s health. It’s foundational.
Which estrobolome type are you?
The Estrobolome Score reads ten key signals across gut symptoms, hormonal patterns, lifestyle factors, and history, and places you into one of four educational profiles, each with an explanation and a clear next step.
The Thriving Estrobolome
At this range, the gut appears to be metabolizing and eliminating estrogen efficiently. The goal is protecting what’s working.
The Burdened Estrobolome
This range is associated with rising beta-glucuronidase activity and early estrogen recirculation. Many women here begin noticing hormonal shifts, a good time to support the estrobolome.
The Disrupted Estrobolome
This range is associated with estrobolome imbalance, more estrogen recirculation, and slower gut transit. Systematic support is often the most helpful next step.
The Depleted Estrobolome
This range is associated with depleted beneficial bacteria and more estrogen recirculation, which many women connect to changes in hormones, mood, skin, and energy.
Discovering their gut-hormone connection
“I’d been to three doctors about my PMS and no one mentioned my gut once. My score came back Disrupted, and for the first time, the gut-hormone connection was actually explained to me. It finally gave me a place to start.”
“I went through this expecting my gut to be fine. I don’t have obvious digestive symptoms. My score came back Burdened, and it gave me a completely new lens on the gut-hormone connection I’d never considered.”
“I’ve been in functional medicine for two years and no one used the word estrobolome with me until Daily Nouri. It explained in three minutes what I hadn’t figured out in two years.”
