HelloPharmacist Scorecard of Inositol 750 mg by Jarrow Formulas

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.

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 750 mg per capsule. Inositol is a carbohydrate compound your body makes naturally and also gets from foods; it plays a role in cell signaling and may affect how your body handles glucose and hormone balance.

The inactive ingredients are hydroxypropyl methylcellulose, water, magnesium stearate, silicon dioxide, and microcrystalline cellulose — standard capsule materials and binders.

Does it work?

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
Not assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: cell membrane function and cellular health.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

Inositol is rated Possibly Effective for polycystic ovary syndrome (PCOS) and metabolic syndrome, and Possibly Effective for preventing preterm labor. For anxiety, diabetic neuropathy (nerve damage from diabetes), and depression, the evidence rates it Possibly Ineffective.

The data we hold doesn't establish effectiveness for other 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 common doses. The most common side effects from oral use are diarrhea, gas, and nausea—typically mild.

One case report described a hospitalization for mania symptoms after consuming a high-caffeine energy drink containing inositol and other ingredients over several days, but it's unclear whether inositol was responsible or if it was caffeine, another ingredient, or a combination. For pregnancy, the safety data rates inositol as Possibly Safe, but clinical use is limited—talk with your doctor or pharmacist before taking it if you're pregnant or planning to become pregnant.

There isn't enough reliable information on lactation, so check with your doctor if you're breastfeeding.

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 antidiabetes drugs (insulin, metformin, sulfonylureas, or others), check your exact medications with the tool on this page before starting inositol—there's a Moderate risk of low blood sugar when combined. For any other prescription medication, use the checker below.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Inositol may help with PCOS, metabolic syndrome, or preterm labor prevention if the evidence supports your situation. The main caution is if you take diabetes medication—low blood sugar risk rises.

Talk with your doctor or pharmacist before starting, especially if you're on any antidiabetes drugs, pregnant, or breastfeeding.

Formula

Jarrow Formulas Inositol is readily absorbed and used to produce the active inositides as necessary. The various forms of inositol (phosphatidylinositol and inositides such as IP3) are active in cell-to-cell communication (such as nerve impulses), including in the brain, liver and muscles. Inositol, also known as myoinositol, is an indirect source of glucuronic acid, which is essential to liver detoxification.

Inositol 750 mg by Jarrow Formulas: Common Questions

Does Inositol 750 mg by Jarrow Formulas interact with any medications?
Yes. Based on its ingredients, Inositol 750 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 750 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.
Will inositol lower my blood sugar if I'm not on diabetes medication?
Inositol does lower blood glucose levels in people with diabetes, but the facts on file don't cover whether it affects blood sugar in people without diabetes. If you're concerned about blood sugar effects, talk with your doctor or pharmacist.
What are the most common side effects?
The main side effects from taking inositol by mouth are diarrhea, gas, and nausea. These are typically mild. One study combining inositol with omega-3 fatty acids in children reported cold and allergy symptoms, but that was with two ingredients together.
Is it safe to take inositol while pregnant?
Inositol is rated Possibly Safe in pregnancy, and it's sometimes studied in that context, but full safety isn't established. Use only under medical supervision if you're pregnant. Talk with your doctor or pharmacist before taking it.
Can I take inositol while breastfeeding?
There isn't enough reliable information on inositol and breastfeeding in our data. Check with your doctor or pharmacist for personalized advice.
Does inositol work for depression or anxiety?
In the data we hold, inositol is rated Possibly Ineffective for both anxiety and depression, so evidence doesn't support its use for those conditions.
What is inositol and where does it come from?
Inositol is a carbohydrate compound your body makes on its own and that's found in foods. In this supplement, it's included at 750 mg per capsule to support metabolism and cell signaling.
