What’s Your Estrobolome Health Score?
Most women have never heard of the estrobolome — the gut bacteria that directly control how your body processes estrogen. This free 3-minute quiz reveals whether yours is thriving, burdened, or depleted, and what that means for your hormones, cycle, energy, and weight.

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. Your liver processes and packages excess estrogen for elimination — but before it leaves your body, it passes through your gut, where estrobolome bacteria determine its fate.
When the estrobolome is healthy, these bacteria ensure estrogen is properly eliminated. When it’s disrupted, an enzyme called beta-glucuronidase reactivates estrogen that was already packaged for excretion and sends it back into circulation. The result is a slow, compounding accumulation of estrogen your body never intended to keep — a primary driver of what’s known as estrogen dominance.
The research is accelerating. In 2026, researchers showed that modern industrialized lifestyles are fundamentally changing how the gut microbiome processes estrogen — increasing estrogen recycling in ways that may explain the rise in estrogen-driven conditions in women. The estrobolome is no longer niche science. It’s one of the most important pieces of your 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.”
Signs your estrobolome might be disrupted
An imbalanced estrobolome rarely announces itself as a gut problem — it shows up as hormone problems. If you recognize three or more of the following, your estrobolome is worth paying attention to:
These symptoms aren’t random, and they’re not inevitable. They’re signals from a gut-hormone axis that needs support.
How your gut controls your estrogen
The connection between gut health and hormones works through a process called enterohepatic circulation — a feedback loop between your liver and digestive system.
Your liver processes excess estrogen and packages it for elimination, sending it to your gut via bile. In a healthy estrobolome, this estrogen is eliminated through stool. But when your gut bacteria are imbalanced — through antibiotics, a low-fiber diet, chronic stress, or hormonal contraceptive use — beta-glucuronidase activity increases, “unwraps” the packaged estrogen, and releases it back into your bloodstream, where it circulates again.
The more disrupted your estrobolome, the more times estrogen recirculates before it’s eliminated. This doesn’t just affect your period — recirculating estrogen affects your mood, your skin, your sleep, your metabolism, and your inflammation levels. The gut-hormone connection isn’t a secondary factor in women’s health. It’s foundational.
Which estrobolome type are you?
The Estrobolome Health Score quiz analyzes ten key signals — gut symptoms, hormonal patterns, lifestyle factors, and history — and places you into one of four profiles, each with a personalized explanation and a clear action plan.
The Thriving Estrobolome
Your gut bacteria are efficiently metabolizing and eliminating estrogen. Hormone balance is your baseline. The goal is protecting what’s working.
The Burdened Estrobolome
Beta-glucuronidase activity is elevated and estrogen is beginning to recirculate. Early estrogen dominance symptoms are likely showing up. This is the best time to intervene.
The Disrupted Estrobolome
Your estrobolome is in clear dysbiosis. Estrogen is actively recirculating and accumulating, and gut transit issues are amplifying the problem. Systematic support is needed.
The Depleted Estrobolome
Beneficial bacteria have been significantly compromised. Estrogen is circulating largely unchecked, affecting hormones, inflammation, gut lining, mood, and immune function at once.
Discovering their gut-hormone connection
“I’d been to three doctors about my PMS and heavy periods and no one mentioned my gut once. My score was 28 — Disrupted. Within six weeks on the reset, my periods were the lightest they’d been in years.”
“I took the quiz expecting my gut to be fine — I don’t have obvious digestive symptoms. My score came back Burdened. The breast tenderness, the brain fog, the weight that won’t move — finally, an explanation.”
“I’ve been in functional medicine for two years and no one used the word estrobolome with me until Daily Nouri. The quiz explained in 3 minutes what I hadn’t figured out in two years.”
