Perimenopause & the estrobolome

The support system your hormones have been waiting for.

In perimenopause, estradiol stops tapering and starts swinging, and the gut bacteria that clear it are shifting at the same time. Hormone Balance Probiotic ES1 is the daily probiotic built for that loop.

So glad I found these!!!
This is my first time ever taking any supplement/ vitamins, and I will be 48 soon. I have always had problems with sleep, and now that I'm in perimenopause it's been so much worse. I started these a month ago and for the first time in my life I am sleeping great! The whole night through! I also feel better through out the day. The only regret I have is not starting these sooner!!!

Symptoms of perimenopause

Six changes women experience and how Hormone Balance Probiotic ES1 supports each

Perimenopause can start in your late thirties and run four to eight years before your final period. These are the changes women describe most, and the part of the gut-hormone loop ES1 is built to support.

Woman in perimenopause
Woman in perimenopause
You notice
Cycles that shorten, lengthen, or arrive heavier
How ES1 supports it

Supports healthy estrogen metabolism through the estrobolome, so estrogen is cleared rather than over-recirculated while your own production swings.

You notice
Bloating and irregularity that weren't there before
How ES1 supports it

Pediococcus acidilactici KABP™-021 and Lactiplantibacillus plantarum KABP™-051 support everyday digestive comfort and regularity while building gut diversity.

You notice
Weight settling differently, especially around the middle
How ES1 supports it

Lactobacillus gasseri KABP™-064 is a cornerstone estrobolome strain also studied for metabolic and weight support.

You notice
Energy and mood that swing with no clear trigger
How ES1 supports it

Supports a steadier gut-hormone connection day to day. The gut has endocrine inputs and outputs that reach far past digestion.

You notice
Skin turning reactive, dull, or uneven again
How ES1 supports it

Lacticaseibacillus rhamnosus SP1 is studied along the gut–skin axis, complementing the estrogen metabolism support the rest of the blend provides.

You notice
Vaginal and urinary changes as estrogen drops
How ES1 supports it

Levilactobacillus brevis KABP™-052 reinforces the gut–immune interface and a balanced vaginal microbiome, part of the whole female-microbiome picture.

Perimenopause & the estrobolome

In perimenopause, your gut has more to say about estrogen than ever. That's the estrobolome.

The estrobolome is the collection of gut bacteria that metabolize and regulate estrogen. It is the control point for how much estrogen is reabsorbed versus eliminated. As ovarian output turns erratic, that control point matters more than it ever has. Hormone Balance supports it at the root.

01
Estrogen swings, then exits

In perimenopause estradiol spikes and drops instead of tapering. Whatever your body makes still ends up in the gut to be cleared.

02
The estrobolome sorts it

Estrobolome bacteria express β-glucuronidase, deciding what gets reabsorbed back into circulation versus eliminated. This is the part of the loop your ovaries don't set.

03
Balance is supported

Hormone Balance supports the microbes that keep estrogen recycling in a healthy range, daily, all the way through the transition.

Under the microscope

This is where the estrobolome lives.

Sectioned and stained, the intestinal mucosa reveals the crypts and villi that house your gut microbiota. Here, along the lower-GI epithelial lining, estrobolome bacteria express β-glucuronidase, the enzyme that decides how much estrogen is reabsorbed versus eliminated. It is the one part of the perimenopausal picture you can support every day.

What it supports

One capsule, support through the transition.

Supports healthy estrogen metabolism

Supports the estrobolome to metabolize and clear estrogen.

Cycles that no longer follow the rules

Helps steady the hormonal ups and downs as cycles become shorter, heavier, or less predictable.

Skin health

A balanced gut shows up on your skin: calmer, clearer, more even.

Digestion & microbiome health

Nurtures a diverse, resilient microbiome. The bloating and irregularity that arrive with perimenopause start here.

How it works over time

Benefits that build, week by week.

The estrobolome responds to consistency, not to a two-week trial. Here's what daily use supports across your first 90 days and beyond.

Weeks 1–2Colonizing the estrobolome
  • The seven strains reach the lower gut, where estrogen is metabolized
  • Estrobolome-active species begin to establish
  • Bloating and irregularity start to ease
Weeks 3–4Estrogen clearance, supported
  • β-glucuronidase activity moves toward a healthy range
  • Less estrogen recycled back into circulation
  • Steadier energy and mood through the swings
Weeks 5–8Cycle and skin follow
  • Cycles feel less erratic month to month
  • Skin looks calmer and more even
  • The perimenopausal peaks and dips soften
Weeks 9–12The full 90-day window
  • Microbial diversity continues to build
  • The gut side of estrogen balance is established
  • The same window most probiotic studies run
90 days & beyondThrough the transition
  • A resilient estrobolome, maintained daily
  • Ongoing estrogen metabolism support
  • Carries from perimenopause into menopause

What's inside

Clinically studied strains, built for the gut-hormone connection.

A targeted blend of clinically studied probiotic strains, chosen for the gut-hormone connection and the years it's under the most strain, delivered in one capsule-in-capsule dose a day.

Precision Probiotic BlendTap to explore ↓

A cornerstone estrobolome strain: it helps keep β-glucuronidase activity in a healthy range, so estrogen is metabolized and cleared rather than over-recirculated through the gut. Also studied for metabolic and weight support.

Works across the estrobolome to crowd out less favorable bacteria and build a diverse, resilient gut community, the foundation that healthy estrogen metabolism depends on. Human-studied alongside IMC-502®.

Paired with IMC-501® to reinforce the gut lining where the estrobolome lives, supporting a strong intestinal barrier and calm, comfortable digestion, keeping the niche favorable for estrogen-regulating microbes.

Supports estrogen metabolism through the estrobolome while reinforcing the gut–immune interface and a balanced vaginal microbiome, part of the whole female-microbiome picture that shifts in perimenopause.

Supports estrogen metabolism by keeping the gut environment stable and favorable for estrobolome activity. A robust, acid-tolerant strain that also eases bloating and maintains regularity.

Supports estrogen metabolism by nourishing gut-lining diversity and short-chain fatty acid production, one of the most-studied and hardiest probiotic species.

Studied along the gut–skin axis: it complements estrogen metabolism support and the clearer, more even skin that comes with a balanced estrobolome.

Not a probiotic. The plant-based omega oil that forms the protective outer capsule. Rich in stearidonic acid (SDA), a highly convertible omega-3 that supports whole-body inflammatory balance while shielding the live cultures on their way to the gut.

Capsule-in-capsule delivery

A capsule, inside a capsule.

Most probiotics lose potency before they ever reach your gut. Our capsule-in-capsule design seals the live cultures inside a protective second shell, so they survive the journey and release where they actually work.

Survives stomach acid

The protective outer shell shields delicate strains from harsh stomach acid.

Releases deeper in the gut

Delayed release delivers cultures to the lower gut, where the estrobolome lives.

2× more live cultures delivered

More strains arrive alive and active, a key reason it's twice as effective.

“As an Integrative Reproductive Endocrinologist, I see the profound impact hormones have on people's lives every day. I am so excited there is now a probiotic that focuses on the foundational role the gut microbiome has on hormone regulation and its downstream effects: metabolism, skin, mood, and fertility.”

“So exciting to have an everyday probiotic that actually supports women's health. The gut has endocrine inputs and outputs that regulate so much, from menstrual cycles and weight to immune function and mood. Women deserve a high-quality probiotic that promotes balance by acting at the intersection of the gut-brain axis.”

Questions

Good questions, straight answers.

01What exactly is the estrobolome?
The estrobolome is the collection of gut bacteria that metabolize and regulate estrogen. It's a key control point for how much estrogen is reabsorbed versus eliminated, which is why your gut has so much to say about hormone balance.
02Why does the estrobolome matter more in perimenopause?
Because two systems destabilize at once. Ovarian estrogen output turns erratic, and the microbiome that helps buffer it is shifting at the same time. Your ovaries aren't something you can act on daily. Your gut is.
03How is this different from a regular probiotic?
Ordinary probiotics use generic blends aimed at digestion. Hormone Balance is built around the gut-hormone connection, with clinically studied strains chosen to support healthy estrogen metabolism at the root.
04I'm still getting my period. Is it too early to start?
No, that's exactly the window this is built for. Perimenopause begins while you're still cycling, often years before periods stop. Starting while the estrobolome is still resilient is the point.
05Can I take it alongside HRT?
Hormone Balance works on gut metabolism, not on hormone replacement. The two act on different parts of the system. Talk to your prescriber about your own regimen before adding anything.
06When will I notice a difference?
Everyone's microbiome is different. Many women feel a difference within the first few weeks, but the estrobolome responds to consistency, so we recommend daily use for at least 8 to 12 weeks.
07Is it safe to take long-term, through menopause and beyond?
Yes. Hormone Balance is made for daily, long-term use across the female lifecycle. As always, check with your doctor if you're pregnant, nursing, or managing a medical condition.
08How do I take it, and how long does a bottle last?
One capsule once a day with water, any time, with or without food. Each bottle is a 30-day supply.
