Most probiotics are one-size-fits-all, built for digestion and sold to everyone. A woman's gut does a job those formulas ignore: through the estrobolome, the gut bacteria that help regulate estrogen, it helps decide how much used estrogen leaves her body. Hormone Balance ES1 is the daily probiotic from a women-owned team, made for that job at every stage of life.

  • 7 clinically studied strains, 12 billion CFU, chosen for the gut–hormone axis
  • Plus 265 mg Ahiflower® Omega 3·6·9 for a calm gut lining, no fish oil
  • One small capsule a day. No hormones, no soy isolates, no stimulants

Not Another Generic Probiotic

Most probiotics are made for everyone. Your body isn't everyone's.

A generic probiotic is formulated around digestion alone. It doesn't account for a monthly cycle, for estrogen that rises and falls, or for the way perimenopause and menopause change the gut. If several of these sound familiar, your probiotic may not have been made with you in mind.

✓

PMS, cramps or mood swings month after month

✓

Breakouts that follow your cycle

✓

Weight that is harder to manage than it used to be

✓

Energy that dips for days at a time

✓

New gut changes in your late 30s or 40s

✓

A label that never mentions hormones or the estrobolome

✓

Strains chosen for digestion only

✓

A formula sold the same way to men and women

The Simple Explanation

How a woman's gut and hormones affect each other, in three steps.

1

Your hormones act on your gut

Estrogen and progesterone both affect how fast food moves through your gut and how much water it holds. As they rise and fall through your cycle, digestion and bloating often change with them.3

2

Your body clears used hormones through your gut

Your liver packages used estrogen and sends it to your gut, so it can leave the body in stool.1

3

Your gut bacteria help decide what stays

Some gut bacteria make an enzyme, β-glucuronidase, that unpacks used estrogen so it is reabsorbed instead of eliminated. Their balance helps decide how much estrogen stays in circulation.2,3

It works in both directions. Your hormones change your gut, and your gut helps regulate your hormones. That is the gut–hormone connection, and your gut is the part of it you can support every day.

Made For Every Woman

One formula for every stage of a woman's life.

Cycling years

A gut that moves with your cycle

Monthly

Estrogen and progesterone rise and fall each month

Support for the estrobolome and a calm gut lining through the week-to-week shifts of a monthly cycle.

Late 30s and 40s

Perimenopause

Variable

Estrogen swings higher and lower

As hormones become less predictable, the gut–hormone connection matters more. The same daily capsule supports it.

Around 51

Menopause

Transition

Hormones settling at a new baseline

The gut microbiome shifts across the menopause transition. Daily support for the estrobolome keeps working with it.

Beyond

Postmenopause

Long term

Estrogen and progesterone stay low

The estrobolome keeps working after your final period, and supporting it remains part of long-term health.

The Estrobolome

Your gut doesn't just react to estrogen. It helps regulate it.

The estrobolome is the collection of gut bacteria that metabolize estrogen. A balanced estrobolome helps used estrogen leave the body. An imbalanced one can produce more β-glucuronidase, sending more estrogen back into circulation.1,2

Researchers describe this as a two-way axis: estrogen shapes the gut microbiome, and the gut microbiome shapes how much estrogen your body keeps.3 Supporting the estrobolome is one of the few parts of hormone balance you can work on every day.

The Gut–Hormone Connection

Your gut supports your hormones. Your probiotic should, too.

Most probiotics were designed for digestion alone. Hormone balance depends on where your gut and your hormones meet, so the probiotic that supports it has to be built for both.

Why Hormone Balance

Made for women: seven strains chosen for the gut–hormone axis.

Hormone Balance ES1 is the daily probiotic built around the estrobolome, the gut bacteria that decide how much used estrogen is cleared and how much is reabsorbed. When that system is in balance, digestion stays more regular, the gut lining stays calm and your hormones have steadier support through the month. That is the gut–hormone connection, and supporting it every day is how you support healthy hormone balance.

Seven clinically studied strains selected for women's gut–hormone health, not a generic digestive blend repackaged for women. Lactobacillus species in particular have been studied for their role in estrogen metabolism and the gut–hormone axis.3

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!!!"

Why Consistency Matters

One capsule a day, built around your cycle.

A probiotic works by establishing itself in your gut, and that is dose- and time-dependent. Because your hormones move in cycles, the clearest way to judge it is across cycles. Here is the arc most women describe.

Weeks 1–2

Digestion settles first

The gut is the fastest-responding piece. Less bloating, more regular days and a calmer stomach after meals.

Weeks 3–6

Your first full cycle

One cycle in, many women notice the week before their period feels different from the last.

Weeks 7–12

The compounding window

By month three you have two or three cycles to compare, and the pattern is usually clear.

✦

Consistency beats intensity. One capsule, every day. Missing a day will not undo your progress, but starting and stopping means the strains never get the chance to establish. Give it at least three cycles.

Proof

1,632 clinicians, including OB/GYNs, share it with patients.

"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."

Dr. Lauren Rubal
Reproductive Endocrinologist

"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."

Before You Buy

Questions women ask us most

What makes this a probiotic for women?+

Most probiotics are built for digestion alone. Hormone Balance ES1 uses seven strains chosen for the gut–hormone axis, plus Ahiflower® Omega 3·6·9 for a calm gut lining, so it supports digestion and the estrobolome together.

Who is it for?+

Women at every stage, from cycling years through perimenopause, menopause and postmenopause. The estrobolome's job changes with you, and one daily capsule supports it throughout.

What is the estrobolome?+

It is the collection of gut bacteria that metabolize estrogen. Some of them make an enzyme called β-glucuronidase that can reactivate used estrogen so it is reabsorbed instead of eliminated. Their balance is part of how your body regulates estrogen.

I already take a probiotic. Can I switch?+

Yes. Most women replace their current probiotic with one Hormone Balance capsule a day. If you are unsure, ask your healthcare provider.

Does it contain hormones or herbs?+

No. There are no hormones, hormone analogues, soy isolates or stimulants. It is seven probiotic strains plus plant-based Ahiflower® Omega 3·6·9, one capsule a day.

Can I take it with birth control or HRT?+

Many women take it alongside other care, but if you use hormonal birth control, HRT or any medication, check with your prescriber before starting.

How quickly will I notice a difference?+

Digestive changes often come first, within the first two weeks. Cycle-related changes take longer because you need a full cycle or two to compare. Give it at least three months of daily use before you judge it.

Do I need to refrigerate it?+

No. Store it at room temperature, out of direct sunlight. Take one capsule daily with water, with or without food.

Is it safe if I'm pregnant or taking medication?+

It's hormone-free, vegan, third-party tested, and free from nine major allergens. If you're pregnant, breastfeeding or taking medication, talk to your healthcare provider before starting, as you should with any new supplement.

What if it doesn't work for me?+

Email hello@dailynouri.com within 30 days of delivery and we'll arrange a return and full refund. We'd rather you tell us it didn't work than quietly give up on it.
