HelloPharmacist Scorecard of Ceylon Cinnamon by Ceylon Cinnamon Shop

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 12, 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. It comes in a vegetarian capsule.

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 Ceylon Cinnamon product and its label doesn't state a use — see Ceylon 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 Ceylon Cinnamon's effectiveness is limited. For obesity and diabetes, the data we hold rates it as possibly ineffective.

For hay fever, COPD, and the common cold, there isn't enough reliable evidence to rate it either way — we simply don't have enough solid research yet.

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.

Ceylon Cinnamon taken by mouth is generally well tolerated, though adverse reactions do occur. The most common are bloating, indigestion (dyspepsia), and nausea.

There's also a single case report of bleeding in a patient who took a tablespoon daily for ten months and had surgery shortly after — the connection is unclear, but it's on the record. A small number of people have reported itching or rashes, and in rare cases, allergic skin reactions have happened, especially in people already sensitized to cinnamon compounds.

For pregnancy, the safety data indicates it's likely safe, though one entry also notes likely unsafe — the evidence is mixed, so talk with your doctor or midwife before using a supplement dose. For breastfeeding, it's rated likely safe, but the safety of supplement doses specifically isn't fully known, so mention it to your OB or pediatrician.

Food amounts are fine; supplement or medicinal doses warrant medical advice first.

Why this rating?

  • 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.

Check with your pharmacist before using this product if you take blood pressure medications or diabetes medications. Both categories carry a Moderate risk of additive effects that could lower your blood pressure or blood sugar too far.

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.

Ceylon Cinnamon may be worth a conversation if you're curious about it, but the evidence that it works for obesity or diabetes is weak. The main concern is if you take blood pressure or diabetes medications — you'd need to check with your pharmacist first.

Food-amount cinnamon is safe; supplement doses need a doctor's green light, especially in pregnancy or while breastfeeding.

Ceylon Cinnamon by Ceylon Cinnamon Shop: Common Questions

Does Ceylon Cinnamon by Ceylon Cinnamon Shop interact with any medications?
Yes. Based on its ingredients, Ceylon Cinnamon 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 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 weight loss or blood sugar?
The evidence we have rates it as possibly ineffective for both obesity and diabetes. So while people take it for those reasons, we don't have solid proof it works for them.
What are the most common side effects?
Bloating, indigestion, and nausea are the most common complaints when taken by mouth. They're uncommon overall, but they do happen. A small number of people have also reported itching or rashes.
Is it safe to take if I'm pregnant?
The safety data is mixed — one entry says likely safe, another says likely unsafe. Because of this uncertainty, talk with your doctor or midwife before you use a supplement dose. Food amounts are fine.
Can I take this while breastfeeding?
It's rated likely safe for breastfeeding, but the safety of supplement doses specifically isn't fully studied. Check with your pediatrician or OB before starting a supplement dose.
Is the capsule itself vegetarian?
Yes, it's made of a vegetarian capsule, so if you avoid animal-derived gelatin, this one works for you.
