HelloPharmacist Scorecard of Cinnamon Extract 500 mg by Puritan's Pride

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 bark extract at 500 mg per serving. The extract comes from cassia cinnamon, a type commonly used in supplements and cooking.

The remaining ingredients — cellulose, dicalcium phosphate, silica, and magnesium stearate — are inactive fillers and binders that hold the capsule 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 Cassia Cinnamon product and its label doesn't state a use — see Cassia 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.

We don't have established evidence that cassia cinnamon effectively treats amenorrhea, angina, the common cold, diabetes, diarrhea, or dyslipidemia (high cholesterol and triglycerides). The data we hold rates all of these uses as having insufficient reliable evidence.

That doesn't mean it doesn't work — it means the evidence isn't settled 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.

Cassia cinnamon is generally well tolerated at food amounts, but this product is a high-dose supplement, so caution applies. The main safety concern is coumarin content — at very high doses taken long-term, it may stress the liver.

In clinical trials with doses ranging from 360 mg to 12 grams daily over 3 months, liver enzymes didn't show significant changes, but the theoretical risk remains, especially over years of use. Rare adverse effects reported include a rash in one trial participant taking 1 gram daily, and contact dermatitis in people with cinnamon allergies.

One participant also reported a low blood sugar event (hypoglycemic seizure), though it's unclear if cinnamon caused it. For pregnancy and breastfeeding, food amounts are likely safe, but high-dose supplements haven't been well studied — talk with your doctor or pharmacist if you're pregnant or nursing.

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.

Check with your pharmacist if you're on antidiabetes drugs (blood sugar medication) or hepatotoxic drugs (medications that can stress the liver). Both categories may need dose review if you add 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.

This cinnamon extract may interest you if you're exploring it for general wellness, but evidence for specific health claims isn't established yet. Be cautious if you take diabetes medication or any drug that can affect your liver — check your meds first.

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 Puritan's Pride: Common Questions

Does Cinnamon Extract 500 mg by Puritan's Pride 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.
Can I take this if I have diabetes?
Cassia cinnamon may lower blood sugar, so it could add to the effect of your diabetes medication. Don't start this without talking to your doctor or pharmacist first — you might need a dose adjustment to stay safe.
Will this hurt my liver?
At food amounts, no. At supplement doses like this one taken long-term, there's a theoretical concern because cinnamon contains coumarin, which can stress the liver in very high doses. Clinical trials haven't shown liver enzyme changes at typical supplement doses, but the risk isn't zero over years of use.
Is it safe to take while pregnant or breastfeeding?
Food amounts are likely safe, but high-dose supplements like this one haven't been well studied in pregnancy and breastfeeding. Talk with your doctor or pharmacist for personalized advice — they can weigh the pros and cons for your situation.
What are the inactive ingredients?
The capsule contains cellulose, dicalcium phosphate, silica, and magnesium stearate — all common binders and fillers that help hold the supplement together.
Has anyone had side effects from this?
In clinical trials, side effects were rare. One person reported a rash at 1 gram daily, and one reported a low blood sugar event — though it's unclear if cinnamon caused that. A few people have had contact dermatitis if they're allergic to cinnamon compounds.
