HelloPharmacist Scorecard of Myo-Inositol for Women and Men by Fairhaven Health

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: myo-inositol, a naturally occurring compound related to B vitamins. The capsule also holds a few inactive ingredients—microcrystalline cellulose, hypromellose, silicon dioxide, and magnesium stearate—which are fillers and binders that help hold the capsule together.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: Supports hormonal balance, ovarian function, and sperm health.
  • We looked for evidence on: Polycystic ovary syndrome (PCOS), Infertility, Metabolic syndrome, Menstrual cycle regularity, Egg quality.
  • The strongest evidence on file: Inositol is rated "Possibly Effective" for Polycystic ovary syndrome (PCOS) (Natural Medicines).
  • Also on file: Inositol is rated "Possibly Effective" for Metabolic syndrome.
  • Also on file: Inositol is rated "Insufficient Reliable Evidence To Rate" for Infertility.

The evidence supports myo-inositol for a few specific uses. It's rated possibly effective for polycystic ovary syndrome (PCOS) and metabolic syndrome.

There's also possibly effective evidence for reducing preterm labor risk. On the other hand, the data don't support its use for anxiety, diabetic nerve pain, or depression—those are rated possibly ineffective.

The evidence, ingredient by ingredient Inositol

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Myo-inositol is generally well tolerated at typical doses. The most common side effects are mild digestive issues: diarrhea, gas, and nausea.

One clinical study found that inositol combined with omega-3s was linked to cold and allergy symptoms in children, though it's unclear whether inositol itself was responsible. Safety in pregnancy hasn't been fully established, so use it only under medical supervision if you're pregnant or planning to become pregnant.

Myo-Inositol for Women and Men by Fairhaven Health: Common Questions

Does Myo-Inositol for Women and Men by Fairhaven Health interact with any medications?
Yes. Based on its ingredients, Myo-Inositol for Women and Men has a known interaction with 86 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Myo-Inositol for Women and Men contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Will myo-inositol help with PCOS?
There's possibly effective evidence for myo-inositol in polycystic ovary syndrome. That means the research supports its use, but it's not a guaranteed cure—talk with your doctor about whether it fits your treatment plan.
What are the side effects?
Most people have mild digestive side effects: diarrhea, gas, or nausea. These tend to be gentle and often improve over time. In one study, children taking inositol with omega-3s reported cold and allergy symptoms, though it's unclear if inositol caused them.
Can I take this if I'm pregnant?
The safety data aren't complete enough to say for sure either way. If you're pregnant or planning to be, talk with your doctor or pharmacist about whether myo-inositol is right for you.
Does myo-inositol help with anxiety or depression?
The research we have doesn't support it for either one—those are rated possibly ineffective. If you're dealing with anxiety or depression, your doctor or pharmacist can suggest options with stronger evidence.
Is it safe to take with my diabetes medication?
Myo-inositol lowers blood sugar, so taking it with antidiabetes drugs could cause your blood sugar to drop too far. Check with your pharmacist or doctor before you start—they may want to monitor you more closely or adjust your dose.
