HelloPharmacist Scorecard of Ceylon Cinnamon Extract Powder 1000 mg by BulkSupplements.com

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 bark extract at 1000 mg per dose. The only other ingredient listed is dextrin, an inactive ingredient used as a filler in the powder.

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 extract is limited. For obesity and type 2 diabetes, the research we hold shows it's possibly ineffective — meaning studies haven't found it works for those uses.

For hay fever, COPD, and the common cold, there isn't enough reliable evidence to rate it either way.

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 extract is generally well tolerated, and side effects are uncommon. The most common ones reported are bloating, indigestion (dyspepsia), and nausea.

A small number of trial participants also reported itching or rashes. There's one rare case report of bleeding in a patient who took cinnamon daily for months before surgery, though it's hard to know if cinnamon was the sole cause.

Supplementstrength doses are less studied than food amounts. Food-level cinnamon is likely fine, but the safety data advises getting medical advice before taking medicinal or supplement doses.

There isn't enough data on file to know whether supplement doses are safe while breastfeeding — talk to your pharmacist or doctor about your personal situation.

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 — Ceylon Cinnamon.
  • 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 taking this if you're on blood pressure medications or diabetes medications — both are Moderate severity interactions that could affect how well your drugs work or how low your blood pressure or blood sugar goes.

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.

If you take blood pressure or diabetes medication, check with your pharmacist before starting this product — the interaction is real and your doses might need adjusting. If you're looking for weight loss or blood sugar help, this extract probably won't deliver.

For food-amount cinnamon, you're fine; for supplement strength, get personalized advice first.

Ceylon Cinnamon Extract Powder 1000 mg by BulkSupplements.com: Common Questions

Does Ceylon Cinnamon Extract Powder 1000 mg by BulkSupplements.com interact with any medications?
Yes. Based on its ingredients, Ceylon Cinnamon Extract Powder 1000 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 Extract Powder 1000 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 Ceylon cinnamon lower my blood pressure?
Animal studies show Ceylon cinnamon extract can relax blood vessels and reduce blood pressure. That's why it interacts with blood pressure medications — the two could work together and lower your pressure too much. If you take a blood pressure drug, you need to check with your pharmacist first.
Can this help my blood sugar?
Ceylon cinnamon may lower blood glucose levels, which is why it interacts with diabetes medications. However, our data shows it's possibly ineffective for diabetes as a treatment — meaning studies haven't found it works for that purpose. If you do take it with a diabetes drug, your blood sugar could drop more than intended, so talk to your doctor about dose adjustments.
What side effects should I expect?
Ceylon cinnamon is generally well tolerated. The most common side effects are mild — bloating, indigestion, and nausea. A small number of people in studies reported itching or rashes. Serious side effects are rare, but there is one case report of bleeding in someone who took a tablespoon daily for months before surgery.
Is it safe to take supplement doses, or should I just use cinnamon as a spice?
Food amounts of cinnamon are likely fine, but supplement-strength doses are less studied. The safety data advises getting medical advice before taking medicinal or supplement doses. This is especially true if you're pregnant, breastfeeding, or taking any medications.
What's in this powder besides the cinnamon?
The only other ingredient is dextrin, which is an inactive filler that helps make the powder work in capsule or drink form. There are no other active ingredients.
