HelloPharmacist Scorecard of Ceylon Cinnamon by Carlson

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, a spice extract available in capsule form. The inactive ingredients — magnesium stearate, silicon dioxide, and beef gelatin — are used as a binder, anti-caking agent, and capsule material.

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: Maintains normal blood glucose.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), blood sugar control, glucose metabolism.
  • 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 Impaired glucose tolerance (prediabetes).

The evidence for cinnamon's usefulness is mixed and limited. For obesity and diabetes, the data we hold shows it's possibly ineffective.

For hay fever, COPD, and the common cold, we don't have enough reliable evidence to rate it either way. If you're considering this supplement for any of those conditions, talk with your doctor about whether it's worth a try or whether other options might be more established.

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 is generally well tolerated at food-level amounts. The most common side effects from supplement doses are bloating, indigestion (dyspepsia), and nausea.

A rare case of bleeding has been reported in someone taking a large daily dose for months, and a few people in small studies reported itching or rashes. Supplement-strength doses are less studied than food amounts, so caution is warranted.

During pregnancy, cinnamon is rated likely safe in food amounts. For breastfeeding, it's rated likely safe, though the safety of supplement doses while nursing isn't established — talk with your doctor or pharmacist for personalized guidance if you're considering this while pregnant or nursing.

Side effects, ingredient by ingredient Ceylon Cinnamon

Meds to double-check

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 — 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.

If you're on blood pressure medication or diabetes drugs, you'll want to check those specific medications with the tool on this page. Ceylon cinnamon may lower blood pressure and blood glucose, and combining it with your prescription could cause a bigger drop than you want.

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 from food sources is safe for most people, but this supplement form is a different story if you take blood pressure or diabetes medication. If you do take either, check your exact drugs here before starting.

The evidence for what cinnamon actually does is thin, so manage your expectations.

Ceylon Cinnamon by Carlson: Common Questions

Does Ceylon Cinnamon by Carlson 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.
Is Ceylon cinnamon safe during pregnancy?
Food amounts are rated likely safe during pregnancy. The safety of supplement-strength doses during pregnancy is less clear, though — there are conflicting ratings in the data. Talk with your doctor or pharmacist about what's right for you.
Can I take this while breastfeeding?
Food amounts of cinnamon are rated likely safe while breastfeeding. The safety of supplement doses while nursing isn't established, so discuss it with your doctor or pharmacist to figure out what makes sense for you.
What side effects should I expect?
Most people don't have problems, but bloating, indigestion, and nausea are the most common complaints. A few people in studies reported itching or rashes. Allergic reactions and skin irritation can happen, especially if you're sensitive to cinnamyl alcohol.
Does Ceylon cinnamon actually help with diabetes or weight loss?
The evidence we hold says it's possibly ineffective for both. If you're hoping cinnamon will manage your blood sugar or weight, don't count on it as a main tool.
Why does the label say 'Ceylon' cinnamon — is that different from regular cinnamon?
Yes — Ceylon comes from a specific type of cinnamon tree and is considered a higher-quality, more delicate version than the cassia cinnamon you see in most grocery stores. The data we track is specific to Ceylon, so that distinction matters for safety and interactions.
