HelloPharmacist Scorecard of Cinnamon Extract 500 mg by Lindberg

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

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: cinnamon extract at 500 mg per capsule. The capsule itself is made up of inactive ingredients — modified cellulose, microcrystalline cellulose, magnesium stearate, and silicon dioxide — which are standard binders and fillers.

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 Cassia Cinnamon's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Promotes healthy glucose metabolism.
  • We looked for evidence on: Diabetes, Dyslipidemia, Impaired glucose tolerance (prediabetes), Obesity.
  • The closest evidence on file: Cassia Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Cassia Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Dyslipidemia, Obesity, Impaired glucose tolerance (prediabetes).

The evidence we hold on cinnamon extract doesn't establish its effectiveness for any of the conditions it's marketed for — including diabetes, high cholesterol, common cold, diarrhea, and amenorrhea. Each one rates as having insufficient reliable evidence.

That doesn't mean it doesn't work; it means the data to confirm benefit isn't there yet.

The evidence, ingredient by ingredient Cassia 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.

Cinnamon is generally well tolerated in food amounts. At supplement doses, though — especially high ones taken for a long time — coumarin in cassia cinnamon may harm the liver over time.

In clinical trials, doses of 360 mg to 12 grams daily for up to 3 months did not significantly raise liver enzymes, but very high coumarin doses (50–7,000 mg daily) have caused liver injury in humans that reversed once the coumarin was stopped. A small number of trial participants reported a rash or, in one case, a low blood sugar episode, though the link to cinnamon wasn't certain.

During pregnancy and breastfeeding, food amounts of cinnamon are likely fine, but avoid medicinal or high-dose supplement amounts because safety data is limited.

Side effects, ingredient by ingredient Cassia 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 — Cassia Cinnamon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 443 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 start this product, double-check with your pharmacist if you take drugs that can harm the liver (hepatotoxic drugs) or diabetes medications. Cinnamon may have additive effects with both, and both interactions are rated 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.

If you take diabetes medication or have liver disease, check with your pharmacist before starting this supplement — cinnamon may lower blood sugar and theoretically could add stress to an already-vulnerable liver. For most other people, cinnamon extract is generally well tolerated, though the evidence for what it actually treats remains unclear.

Talk to your pharmacist about your personal medications.

Antidiabetes Drugs

Theoretically, cassia cinnamon may have additive effects with antidiabetes drugs.
Cassia cinnamon may lower blood glucose levels, and have additive effects in patients treated with antidiabetic agents. Dose adjustments to diabetes medications might be necessary.

Likelihood Possible Evidence B
Hepatotoxic Drugs

Theoretically, large doses of cassia cinnamon might cause additive effects when used with hepatotoxic drugs.
There is some concern that ingesting large amounts of cassia cinnamon for an extended duration might cause hepatotoxicity in some people. Cassia cinnamon contains coumarin, which can cause hepatotoxicity in animal models. In humans, very high doses of coumarin from 50-7000 mg/day can result in hepatotoxicity that resolves when coumarin use is discontinued. Lower amounts might also cause liver problems in sensitive people, such as those with liver disease or those taking potentially hepatotoxic agents.

Cinnamon Extract 500 mg by Lindberg: Common Questions

Does Cinnamon Extract 500 mg by Lindberg interact with any medications?
Yes. Based on its ingredients, Cinnamon Extract 500 mg has a known interaction with 442 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cinnamon Extract 500 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.
Is this safe to take during pregnancy or while breastfeeding?
Food amounts of cinnamon are likely safe, but this supplement dose — especially taken long-term — hasn't been studied enough during pregnancy or breastfeeding. The safety data advises against medicinal or high-dose supplement amounts. Talk with your doctor or pharmacist for personalized advice on whether this product is right for you.
Does cinnamon actually work for diabetes?
The evidence we have doesn't establish that it does. The rating is insufficient reliable evidence. So while cinnamon may lower blood sugar theoretically, we don't have solid proof yet that it helps treat diabetes — and if you do take diabetes medication, you'd need to be careful about additive effects anyway.
What are the side effects?
In clinical trials, a small number of participants reported a rash. There's also a theoretical concern about liver stress with very high doses taken over a long time, since cinnamon contains coumarin. In one trial participant, a low blood sugar episode was reported, though it's unclear if cinnamon caused it.
Why does the bottle say 500 mg if cinnamon is safe in food?
Food amounts of cinnamon — like a pinch in your coffee — are generally safe. But 500 mg is a concentrated supplement dose, which is much larger and carries the theoretical risks we've covered, especially over time and if you have liver or diabetes concerns.
Will this interact with my blood pressure or cholesterol medications?
No interactions are documented in our data for blood pressure or cholesterol drugs. That said, use the search tool on this page to check your exact medications — that's the safest way to be sure.
