The part people don’t always see.
Late periods. Skipped months. Another week of wondering what your body is doing.
Stubborn acne. Unwanted facial hair. Another thing to manage before leaving the house.
The checking. The covering up. The feeling that your body has become another job.
PCOS is already demanding enough. Getting support should feel simpler.

Why women consider inositol.
PCOS connects all three. Inositol research looks at them together.
For the months that keep you guessing.
Late periods. Skipped months. Checking the calendar again. When PCOS makes your cycle unpredictable, it can take up more of your day than anyone sees.
Where inositol fits.
Clinical trials have reported more regular menstrual cycles with inositol. Cycle support is one of the reasons women include it in their PCOS care.
The insulin connection, made simple.
Inositol is a compound your body makes and gets from food. It helps carry signals inside your cells.
Insulin helps your cells take up glucose from your blood.
Insulin resistance can lead to higher insulin levels. This can fuel excess androgens, which can disrupt ovulation.
Its role in insulin signalling is why researchers are studying supplementation for metabolic support.

Why this formula.
Related forms with roles in the body’s insulin-signalling pathways. They’ve been studied individually and together for metabolic and reproductive health.
That’s what 40:1 means. A combination studied in women with PCOS, with the ratio clearly stated on every pouch.
4g of inositol per serving. Unflavored powder. A month’s supply in each pouch. Mix it into a drink you already enjoy.

Keep the routine simple.
Add to water or your drink of choice. Follow the serving directions on your pouch.
Breakfast, an afternoon pause, your usual drink. Choose a moment that’s easy to remember.
Make it a daily habit. Track your cycle and any changes you notice, so you have something concrete to review with your clinician.
What to expect
PCOS care takes time. Give yourself a routine you can keep, and a clear point to review it.
Note your usual cycle pattern and what you’d like support with. Share your plan with your clinician.
Follow your pouch directions and pair your serving with a familiar moment. Consistency matters more than a complicated ritual.
Studies often follow women for three to six months. Review your cycle record and how you’re feeling with your clinician.
If periods are absent or very infrequent, seek medical advice promptly as part of your PCOS care.
The research behind the routine.
Explore the findings on menstrual cycles, metabolic measures and hormone levels.
01 / Metabolic measures
A small six-month trial of a 40:1 blend found improvements in insulin resistance and some hormone measures in women with PCOS. It used a different dose and formulation from this product.
Benelli et al., 2016 ↗02 / Cycle regularity
A 2023 analysis found more regular cycles with inositol than placebo across studies using different formulations.
Greff et al., 2023 ↗03 / The wider picture
The international PCOS guideline includes inositol as an option to consider with your clinician, based on your preferences and priorities.

Choose my inositolThe formula & benefits
Inositol occurs naturally in your body and in foods including fruit, beans and grains. It is involved in signals inside your cells, including insulin signalling. Research in PCOS has explored benefits for menstrual regularity, insulin sensitivity and hormone measurements. Our blend combines myo-inositol and D-chiro-inositol in a 40:1 ratio. See the research.
Clinical trials have reported improved menstrual regularity with inositol. Track your cycle as part of your routine, and seek medical advice promptly if periods are absent or very infrequent.
These are areas of research, but improved ovulation, egg quality or pregnancy outcomes have not been reliably established. If you’re trying to conceive, discuss inositol with your fertility clinician as part of your wider plan. It isn’t a replacement for fertility treatment or a prenatal supplement.
No. Cycle and metabolic health matter whether or not pregnancy is part of your plans. We brought inositol to Deen Health for women looking at their everyday PCOS care, too.
Studies have reported changes in some androgen levels, but that doesn’t reliably translate into clearer skin or less facial hair. These symptoms deserve their own care plan; don’t rely on inositol alone to address them.
They are two related forms of inositol involved in insulin-signalling pathways. Our 40:1 blend means 40 parts myo-inositol to one part D-chiro-inositol. Researchers have studied both forms, individually and together, in women with PCOS.
Your daily routine
Mix your serving into water or your usual drink, following the measuring and daily-use directions on your pouch. Each serving provides 4g of inositol, and each pouch is a one-month supply. It’s unflavored, so it fits into a drink you already enjoy.
Build a consistent daily habit. Studies often run for three to six months, so plan a review around three months with your clinician. Bring your cycle record and notes on how you’re feeling.
Your clinician or pharmacist can help check how inositol fits with your medication. This is especially important with metformin or other medicines that affect blood sugar. Keep taking prescribed treatment unless your clinician advises a change.
Check with your maternity clinician before starting or continuing. They can review your needs alongside the supplements and medicines you already take.
Inositol is generally well tolerated in studies, though nausea, bloating or other digestive discomfort can occur. Follow the label directions. If it makes you feel unwell, pause and ask your clinician for advice.

A personal note from our founder.
I brought Inositol to Deen Health because PCOS can affect far more than a period. There’s the calendar you keep checking, changes in your skin, and the frustration of trying to understand what your body needs.
I want our Sisters to understand their options without having to make sense of a research paper on their own.
One important connection is insulin. When the body struggles to respond to it, that can also affect the hormones involved in ovulation. Inositol plays a role in insulin signalling, which is why researchers have studied it for PCOS.
That connection is what makes inositol worth our attention. We brought together myo-inositol and D-chiro-inositol in a 40:1 blend, with a simple daily routine and clear information about the research behind it.
My aim is simple: help you understand your body, feel supported, and take your next step with confidence.
