Solving The Problem You're Experiencing
Your digestion has a schedule. It just isn't yours.
Most advice about regularity assumes your gut behaves the same way every day. For women it doesn't. Transit slows in the second half of the cycle and speeds up when your period starts, and the microbiome that sets your baseline is shaped by the same hormones.1 If several of these sound familiar, this page is for you.
✓
Most common
Constipation in the week before your period
✓
Loose stools or urgency on the first day or two of your period
✓
Bloating that builds through the afternoon
✓
Days where you go, but it never feels finished
✓
Hard stools one week, soft the next, rarely in between
✓
Gas and a tight, heavy belly after meals
✓
You rely on coffee or a laxative to get things moving
✓
A digestive probiotic that helped a little, then stopped
✓
You want regular to mean every day, not most days
The Simple Explanation
Why regularity changes across the month, in three steps.
1
Progesterone slows the gut
After ovulation, progesterone rises. It relaxes smooth muscle, including the muscle of your colon, so transit slows. Stool sits longer, loses water and gets harder to pass. This is the pre-period slowdown.1
2
Prostaglandins speed it up
When your period starts, prostaglandins contract the uterus to shed its lining. They also act on the bowel next door, which is why day one often brings looser, more urgent stools.1
3
Your gut bacteria set the baseline
Underneath the monthly swing, your microbiome shapes stool consistency and transit time every day.3 It also metabolizes estrogen, so the gut that keeps you regular and the gut that handles your hormones are the same gut.4
Steps one and two are your cycle doing its job. Step three is the part you can support every day. A stable, well-fed microbiome gives the monthly swing a steadier baseline to swing around.
What Sets Your Rhythm
Four things that decide whether today is a regular day.
Days 1–3
Prostaglandins
Speeds transitStart of your period
Prostaglandins released to shed the uterine lining also stimulate the bowel, which can mean loose stools and cramping.1
Every day
Your microbiome
Supportable dailyComposition · richness
In a large population study, stool consistency was strongly associated with gut microbiome richness and composition.3
Every day
Fiber and water
Daily inputsBulk · hydration
Fiber adds bulk and feeds your gut bacteria. Water keeps stool soft. Both matter more in the slow week.
Regularity And Hormones
Regularity and your hormones are connected in both directions.
Used estrogen leaves your body in stool. The estrobolome, the gut bacteria that metabolize estrogen, helps decide whether it leaves or gets reabsorbed. When transit is slow, estrogen sits in the gut longer and more of it can be taken back up.4,5
73%
of healthy women reported at least one gastrointestinal symptom before or during their period in a survey study.1
12.4 hrs
shorter whole-gut transit time with probiotics versus placebo, across randomized trials in adults with constipation.2
Direction 1 · Hormones → Gut
Your cycle changes how your gut moves
Progesterone and prostaglandins change transit speed week to week. Estrogen also shapes which bacteria thrive, so the microbiome itself shifts across the month.1,4
Direction 2 · Gut → Hormones
Your gut changes how much estrogen you keep
Slow transit and an imbalanced estrobolome mean more used estrogen is reabsorbed instead of eliminated. Regular bowel movements are part of a healthy estrogen exit route.4,5
This is why a probiotic for women should not stop at digestion. Regularity is a gut outcome and a hormone outcome at the same time, and the formula should be built for both.
The Gut–Hormone Connection
Your gut moves with your hormones. Your probiotic should, too.
Most probiotics were designed for digestion alone. Regularity that holds across the month depends on where your gut and your hormones meet, so the probiotic that supports it has to be built for both.
Why Hormone Balance
Seven strains for a gut that keeps up with your cycle.
Hormone Balance ES1 is the daily probiotic built around the gut–hormone axis. Seven clinically studied strains support a stable, diverse microbiome, the baseline your regularity rests on, and the estrobolome that clears used estrogen. A plant-based omega supports a calm gut lining. One capsule a day, no laxatives, no fiber powders to mix.
12 BILLION CFU
The 7-strain probiotic complex
Seven clinically studied strains selected for women's gut–hormone health, not a generic digestive blend repackaged for women. In pooled randomized trials, probiotics improved stool frequency and transit time in adults with constipation; effects are strain-specific, and each strain here is documented with its code.2

Not a laxative. Hormone Balance works on the baseline, the microbiome that sets your everyday rhythm, rather than forcing a bowel movement. That is why it is taken daily, and why the difference builds over weeks.
Why Consistency Matters
Regular days come first. A steadier cycle follows.
A probiotic works by establishing itself in your gut, and that is dose- and time-dependent. Digestion usually responds within weeks. The pre-period slowdown takes a cycle or two to compare. Here is the arc most women describe.
Weeks 1–2
More regular days
The gut is the fastest-responding piece. Less bloating, softer and more predictable bowel movements, a calmer stomach after meals.
Weeks 3–6
Your next slow week
One full cycle in is often when women first notice the week before their period is less backed up than usual.
Weeks 7–12
The compounding window
By month three you have two or three cycles to compare. The baseline has had time to build, and regular has started to mean every day.
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 about regularity
Why do I get constipated before my period?+
Progesterone rises after ovulation and relaxes smooth muscle, including your colon. Transit slows, stool loses water and becomes harder to pass. It is one of the most common cycle-related gut symptoms.
Why do I get loose stools when my period starts?+
Prostaglandins released to contract the uterus also act on the bowel, speeding things up. Day one or two is often the loosest point of the month for the same reason cramps peak then.
Can a probiotic help with regularity?+
In pooled randomized trials, probiotics improved stool frequency and shortened gut transit time in adults with constipation. Effects are strain-specific. Hormone Balance supports a stable microbiome, the baseline your regularity rests on; it is not a laxative and not a treatment for any condition.
How is this different from fiber or a laxative?+
A laxative forces a single bowel movement. Fiber adds bulk. A probiotic works on the bacteria that set your everyday rhythm. They are complementary: keep the fiber and water, and let the probiotic build the baseline.
Will it make me gassy or bloated at first?+
Some women notice mild changes in the first week as the strains establish. It usually settles. If it does not, take it with food and contact us; we are happy to help.
What does regularity have to do with hormones?+
Used estrogen leaves your body in stool. When transit is slow, it sits in the gut longer and more of it can be reabsorbed. Regular bowel movements are part of a healthy estrogen exit route, which is why this formula is built for both.
Does it contain hormones, laxatives or stimulants?+
No. There are no hormones, hormone analogues, senna, soy isolates or stimulants. It is seven probiotic strains plus plant-based Ahiflower® Omega 3·6·9, one capsule a day.
How quickly will I notice a difference?+
Digestive changes often come first, within the first two weeks. The pre-period slowdown takes a cycle or two to compare. Give it at least three months of daily use before you judge it.
Should I take it with food?+
Either is fine. Take one capsule daily with water, with or without food, at whatever time makes it easiest to remember. No refrigeration needed.
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.
