HelloPharmacist Scorecard of Inositol 1000 mg by Double Wood Supplements

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: inositol at 1000 mg per capsule. Inositol is a naturally occurring compound related to vitamin B that your body makes and also gets from food.

The only other ingredient listed is hypromellose, which is a standard capsule material.

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: cellular signaling and metabolic support.
  • We looked for evidence on: Anxiety, Depression, Metabolic syndrome, Panic disorder, Polycystic ovary syndrome (PCOS), insulin resistance — and 2 related terms.
  • 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 "Possibly Ineffective" for Anxiety, Depression.

Inositol shows the most promise for polycystic ovary syndrome (PCOS), metabolic syndrome, and preterm labor, where it's rated possibly effective based on available research. However, for anxiety, diabetic nerve pain (diabetic neuropathy), and depression, the evidence is rated possibly ineffective—meaning studies haven't shown it works well for these uses.

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.

Inositol is generally well tolerated at typical doses. The most common side effects when taken by mouth are mild digestive issues: diarrhea, gas, and nausea.

When inositol was combined with omega-3 fatty acids in clinical research with children, a small number of participants reported cold and allergy-like symptoms. Safety in pregnancy hasn't been fully established, though inositol has been studied in pregnant patients.

Because the data isn't complete, use it in pregnancy only under direct medical supervision. There isn't enough reliable information on inositol in other situations either, so check with your doctor or pharmacist before starting, especially if you have any health conditions.

Side effects, ingredient by ingredient Inositol

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Inositol.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 86 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

If you take any antidiabetes drug—insulin, metformin, glyburide, or any other medication to lower blood sugar—double-check it with your pharmacist before adding inositol. The combination raises your risk of low blood sugar.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you have PCOS, metabolic syndrome, or are facing preterm labor risk, inositol may be worth discussing with your doctor. The biggest caution is if you take diabetes medication—low blood sugar becomes a real possibility.

Talk to your pharmacist before you start, particularly about your current medications and whether inositol fits your situation.

Inositol 1000 mg by Double Wood Supplements: Common Questions

Does Inositol 1000 mg by Double Wood Supplements interact with any medications?
Yes. Based on its ingredients, Inositol 1000 mg 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?
Inositol 1000 mg 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.
Can I take inositol if I'm pregnant or trying to become pregnant?
Safety in pregnancy hasn't been fully established, even though inositol has been studied in pregnant women. If you're pregnant or planning to become pregnant and want to use inositol, you need to do it only under direct medical supervision. Talk to your doctor or OB/GYN first.
What are the side effects I might experience?
Most side effects are mild and digestive: diarrhea, gas, and nausea. In research where inositol was combined with omega-3 fatty acids in children, a small number reported cold and allergy-like symptoms. Overall, inositol is generally well tolerated.
Does inositol actually work for PCOS?
For PCOS, inositol is rated possibly effective based on available research. That means there's evidence it may help, but it's not definitive. Talk with your doctor about whether it makes sense as part of your treatment plan.
Will inositol help my depression or anxiety?
For anxiety and depression, the evidence is rated possibly ineffective—studies haven't shown inositol works well for these conditions. It's not recommended as a first choice for either.
Why can't I just take inositol with my diabetes medication?
Inositol lowers blood sugar levels on its own. If you combine it with diabetes medication, your blood sugar might drop too low (hypoglycemia), which can be dangerous. Your doctor or pharmacist may still allow it with close monitoring and dose adjustments, but you need to check first.
Is there anything else in these capsules besides inositol?
The capsules contain hypromellose, which is a standard capsule material. There are no other active ingredients.
