HelloPharmacist Scorecard of Pure Ceylon Cinnamon 1500 mg by HerbTonics

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 Sep 10, 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: Ceylon cinnamon at 1,500 mg per capsule. Cassia cinnamon — the species our safety data covers — has been studied for various uses including blood sugar control and cholesterol support, though the evidence for most of these remains uncertain.

The capsule also contains cellulose, an inactive ingredient used as a binder and filler.

Does it work?

Couldn't assess
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

This is a single-ingredient Cassia Cinnamon product and its label doesn't state a use — see Cassia Cinnamon's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for cinnamon's effectiveness isn't established in our data. We hold insufficient reliable evidence to rate it for amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia.

If you're considering this product for a specific health goal, talk with your doctor or pharmacist about what the research actually supports and whether it makes sense for you.

The evidence, ingredient by ingredient Cassia Cinnamon

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.

Cinnamon in food amounts is generally well tolerated. But at supplement doses — especially high doses taken over weeks or months — there's a concern about liver harm from coumarin, the compound cinnamon contains.

Very high doses of coumarin (50–7,000 mg daily) have caused liver damage in humans, though it reversed when people stopped. In clinical trials, doses of 360 mg to 12 grams daily for three months didn't significantly raise liver enzyme levels, but caution is still warranted with long-term use.

In clinical trials and case reports, a small number of people reported a rash or eyelid dermatitis linked to cinnamon. One person also had a seizure during a trial, though it's unclear if cinnamon caused it.

During pregnancy and breastfeeding, food amounts appear safe, but high-dose supplements aren't recommended due to limited safety data.

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 — Cassia Cinnamon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 443 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.

Check with your doctor or pharmacist before taking this product if you use diabetes medications (insulin or oral drugs to lower blood sugar), since cinnamon may lower glucose further. Also flag any medications known to harm the liver — cinnamon may add to that risk at high doses.

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.

Pure Ceylon Cinnamon may be worth considering if you're interested in herbal supplements, but it's not established for any of the conditions listed in our data. If you take medications for blood sugar control or liver function, or any drug that stresses your liver, check with your doctor or pharmacist before starting — dose adjustments or closer monitoring might be needed.

Stick with lower doses and avoid long-term high-dose use.

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Pure Ceylon Cinnamon 1500 mg by HerbTonics: Common Questions

Does Pure Ceylon Cinnamon 1500 mg by HerbTonics interact with any medications?
Yes. Based on its ingredients, Pure Ceylon Cinnamon 1500 mg has a known interaction with 442 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Pure Ceylon Cinnamon 1500 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 this cinnamon supplement help my blood sugar?
The evidence isn't strong enough to say for sure. We hold insufficient reliable evidence to rate cinnamon for diabetes. Talk with your doctor about whether it's worth trying alongside your other diabetes management.
Is cinnamon safe to take long term?
At food amounts, yes. But at supplement doses, especially high doses for weeks or months, there's concern about liver damage from coumarin, a natural compound in cinnamon. Very high doses have caused liver problems in humans before. Lower doses in clinical trials didn't raise liver markers, but long-term safety data is still limited.
Can I take this while pregnant or breastfeeding?
Food amounts of cinnamon appear safe during pregnancy and breastfeeding. High-dose supplements aren't recommended, though, because the safety data is limited. Talk with your doctor or pharmacist about what's right for you.
What's in this besides the cinnamon?
The capsule contains cellulose, which is an inactive binder and filler. That's it.
Could cinnamon cause a rash or other skin problems?
In clinical trials and case reports, a small number of people developed a rash or eyelid dermatitis tied to cinnamon, especially if they had a sensitivity to cinnamic alcohol. Most people tolerate it well, but if you notice any skin changes after starting, stop and talk with your doctor.
How much coumarin is in this dose?
That information isn't in our product data. If you're concerned about coumarin exposure — especially if you have liver issues — ask your pharmacist or check with the manufacturer.
