HelloPharmacist Scorecard of Ceylon Cinnamon 1200 mg by Number One Nutrition

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: Ceylon Cinnamon at 1200 mg per capsule. The capsule also holds inactive ingredients (cellulose and microcrystalline cellulose), which are standard binders and fillers.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Cassia Cinnamon's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Supports immune health.
  • We looked for evidence on: Common cold.
  • The closest evidence on file: Cassia Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Common cold (Natural Medicines).

The evidence we hold on cinnamon for its common uses — amenorrhea, angina, common cold, diabetes, diarrhea, and dyslipidemia — is insufficient to rate. That means clinical trials haven't yet established whether it really works for these purposes.

If you're considering cinnamon for a specific health goal, talk with your pharmacist or doctor about what the current evidence actually shows.

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 is generally well tolerated in food amounts, but this supplement dose is much higher. The main safety concern is the coumarin content.

Very high intakes of coumarin (50–7000 mg per day) can harm the liver, though symptoms go away once you stop. In clinical trials, doses from 360 mg to 12 grams daily for three months didn't significantly raise liver enzymes in the people tested.

That's reassuring but not a guarantee of safety for everyone, especially with long-term use. Rare side effects reported include a rash (one patient on 1 gram daily) and in one case, contact dermatitis in someone with a cinnamon allergy.

A single hypoglycemic seizure (low blood sugar event) was reported, though it's unclear if cinnamon caused it. During pregnancy and breastfeeding, food amounts are fine, but avoid high-dose supplements — there isn't enough safety data.

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 — 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 pharmacist before taking this product if you're on diabetes medications (blood sugar–lowering drugs) or hepatotoxic drugs (medications that can stress the liver). Both are Moderate severity interactions.

Blood sugar may drop further, and liver strain could add up. Use the checker on this page with your exact medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Ceylon Cinnamon 1200 mg is generally well tolerated at this dose, but it's not a proven treatment for the common conditions people take it for. If you take diabetes drugs or medications that stress your liver, you need to check with your pharmacist or doctor first — this supplement could affect how those work.

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.

Ceylon Cinnamon 1200 mg by Number One Nutrition: Common Questions

Does Ceylon Cinnamon 1200 mg by Number One Nutrition interact with any medications?
Yes. Based on its ingredients, Ceylon Cinnamon 1200 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?
Ceylon Cinnamon 1200 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.
Does Ceylon Cinnamon actually help with diabetes?
The evidence we have is insufficient to rate. Clinical trials haven't yet proven it works for diabetes, so we can't say yes or no based on the data. Your doctor is the best person to discuss whether it might help in your case.
Is it safe to take this while I'm pregnant or breastfeeding?
Food amounts of cinnamon are fine, but this supplement at 1200 mg per capsule is a medicinal dose. The safety data is limited, so avoid high-dose supplements during pregnancy and breastfeeding — talk with your doctor or pharmacist for personalized advice.
What's coumarin, and why should I worry about it?
Coumarin is a natural compound in cinnamon that, in very high amounts over time, can stress your liver. At the doses tested in humans (360 mg to 12 grams daily for three months), liver damage hasn't been significant, but long-term high-dose use is a concern worth monitoring with your doctor.
Can I take this if I'm already on a blood thinner?
The interactions we hold data on don't include blood thinners specifically. Use the medication checker below with your exact drug name, or ask your pharmacist — they can tell you if there's a risk with your particular medicine.
What side effects should I watch for?
Side effects are rare. A rash and contact dermatitis have been reported in very small numbers of people. One person had a low blood sugar event, though it's unclear if cinnamon caused it. Stop and contact your doctor if you experience unusual symptoms.
