What’s inside

Full disclosure
Ingredient Transparency · database check

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.

Nature's Craft Ceylon Cinnamon is a single-ingredient supplement: organic Ceylon cinnamon powder in tablet form. The product also contains inactive ingredients — acacia gum, rice extract, rice husk, gum arabic, sunflower oil, organic silica concentrate, and silicon dioxide — which are fillers and binders that help hold the tablet together.

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 is mixed and limited. For obesity and diabetes, the data suggests it's possibly ineffective.

For allergic rhinitis (hay fever), common cold, and chronic obstructive pulmonary disease (COPD), there isn't enough reliable evidence yet to say whether it works. If you're considering this supplement for one of these conditions, talk with your pharmacist or doctor about whether the evidence supports it for your situation.

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 when taken as a supplement. The most common side effects are mild: bloating, indigestion (dyspepsia), and nausea — and adverse reactions are uncommon.

There is one case report of bleeding in a patient who took a tablespoon of Ceylon cinnamon daily for months before surgery, so if you're having a procedure, let your doctor know you're taking this. Rarely, people have reported itching, rashes, or allergic contact reactions; if you develop a rash or itching after starting, stop and contact us.

For pregnancy, food amounts of cinnamon are likely safe, but the safety data on supplement doses during pregnancy is conflicting — some sources say likely unsafe. During breastfeeding, food amounts are likely safe, but the safety of supplement doses isn't well studied.

If you're pregnant or nursing, discuss this with your doctor or pharmacist before taking supplement-strength doses.

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 — 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.

Before you take this Ceylon cinnamon supplement, double-check if you're on blood pressure medication or diabetes medication (the two most concerning types). Both carry Moderate risk of dose-related effects if combined with this supplement.

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 is a single-ingredient supplement that's generally well tolerated at food-dose levels. If you take blood pressure or diabetes medication, you'll want to check with us first — the supplement may strengthen those drugs' effects.

Ceylon Cinnamon by Nature's Craft: Common Questions

Does Ceylon Cinnamon by Nature's Craft 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.
Will Ceylon cinnamon help my blood sugar or weight?
The evidence doesn't support it right now. For both obesity and diabetes, the data suggests Ceylon cinnamon is possibly ineffective. If you're interested in supplements for either condition, ask your pharmacist about what the evidence actually shows.
What are the most common side effects?
Bloating, indigestion, and nausea are the main ones people report, and they're uncommon. Most people tolerate it well. If you notice a rash or itching, that's rare but can happen — stop and let us know.
Is it safe to take if I'm pregnant or breastfeeding?
Food amounts are likely safe when you're nursing, but the data on supplement-strength doses during pregnancy is unclear — some sources say they're not safe. If you're pregnant or breastfeeding, talk with your doctor or pharmacist before taking this supplement at medicinal doses.
What's the difference between food cinnamon and this supplement?
The supplement contains much higher doses than you'd get from a pinch of cinnamon in your coffee or oatmeal. Food amounts are well-studied and safe; supplement doses are less studied, so they need more caution — especially if you're pregnant, breastfeeding, or on medications.
Can I take this if I'm having surgery?
There's one case report of bleeding after taking a large amount of cinnamon for months before surgery. If you're scheduled for a procedure, tell your surgeon or anesthesiologist you're taking this supplement.
