HelloPharmacist Scorecard of Ceylon Cinnamon 1,200 mg by Nature's Lab

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: Ceylon cinnamon at 1,200 mg per capsule. The rest of the capsule is made up of inactive ingredients like hypromellose (the capsule shell itself), rice, rice extract, gum acacia, and sunflower oil.

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 Ceylon Cinnamon's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Ceylon Cinnamon wellness support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Dyspepsia, Diarrhea, Blood sugar control, Cholesterol management — and 2 related terms.
  • The closest evidence on file: Ceylon Cinnamon is rated "Possibly Ineffective" for Diabetes (Natural Medicines).
  • Also on file: Ceylon Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Diarrhea, Dyspepsia, Impaired glucose tolerance (prediabetes).

The evidence for Ceylon cinnamon as a supplement is mixed at best. For weight loss and diabetes, the data we hold rates it as possibly ineffective — meaning the studies don't show it works for these uses.

For hay fever, COPD, and the common cold, we don't have enough reliable evidence to rate it one way or another. Bottom line: Ceylon cinnamon at supplement doses isn't proven to treat these conditions.

The evidence, ingredient by ingredient Ceylon 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.

Orally, Ceylon cinnamon is generally well tolerated, and most people don't have side effects. When they do occur, the most common ones are bloating, indigestion, and nausea.

Allergic reactions like itching or rashes have been reported in a small number of people. There's also a rare case report of bleeding in a patient who took a tablespoon daily for months after surgery — something to keep in mind if you're having surgery or taking blood thinners.

As a food spice, cinnamon is safe; supplement-strength doses are less studied, so use caution. We don't have safety data on supplement doses during breastfeeding, so talk with your doctor or pharmacist before using this at medicinal strength.

  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 258 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 blood pressure medications or diabetes drugs, check your specific medications with our search tool before starting this product. These are the two medication types Ceylon cinnamon can interact with, both at Moderate severity.

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 is a common kitchen spice that's generally well tolerated at food amounts. At supplement doses like this one, it's less proven to work and carries potential interactions with blood pressure and diabetes drugs.

If you take either of those medication types, check your exact drugs with our tool before starting. If you don't take those medications and want to try it, just watch for bloating or nausea and talk with your pharmacist if side effects pop up.

Formula

Cinnamon is a spice obtained from the Cinnamomum genus of trees native to Sri Lanka. The bark of this tree is prized for its potential wellness benefits with use dating back thousands of years. Ceylon Cinnamon (Cinnamomum verum) possesses plant antioxidants in the form of phenols and flavonoids that provide support against damaging free radical molecules. Ceylon cinnamon is prized for its effect on balancing the body's use of carbohydrate fuel for healthy energy levels.

Ceylon Cinnamon 1,200 mg by Nature's Lab: Common Questions

Does Ceylon Cinnamon 1,200 mg by Nature's Lab interact with any medications?
Yes. Based on its ingredients, Ceylon Cinnamon 1,200 mg has a known interaction with 258 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ceylon Cinnamon 1,200 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 work for weight loss or blood sugar?
Based on the research data we have, Ceylon cinnamon rates as possibly ineffective for both weight loss and diabetes. That doesn't mean you can't try it, but the evidence doesn't back up those claims, so go in with realistic expectations.
What are the most common side effects?
Bloating, indigestion, and nausea are the ones reported most often. Most people taking it don't have any problems, but if your stomach gets upset, that's the most likely culprit.
Is Ceylon cinnamon safe to use every day?
As a food spice, yes — people eat it all the time. At supplement-strength doses like this, there's less long-term safety data. Stick to food amounts if you want to be safest, and talk with your pharmacist before taking a supplement dose regularly.
Can I take this if I'm having surgery?
There's a rare case report of bleeding in someone who took cinnamon daily and then had surgery. If you're scheduled for a procedure, mention this supplement to your surgeon or doctor beforehand so they can advise you on whether to pause it.
Is this safe during breastfeeding?
We don't have safety data on supplement-strength cinnamon doses while breastfeeding. Food amounts are fine, but for this product at medicinal doses, talk with your doctor or pharmacist first — they can give you personalized advice based on your situation.
What makes Ceylon cinnamon different from regular cinnamon?
The product facts we have focus on Ceylon cinnamon specifically. The facts don't detail how it differs from other types, so that's a good question for your pharmacist.
