HelloPharmacist Scorecard of CinnaMedic Cinnamon by Wonder Laboratories

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.

CinnaMedic Cinnamon is a single-ingredient product: Cinnulin PF, a standardized extract of cassia cinnamon. The capsule also contains three inactive ingredients—cellulose, silica, and magnesium stearate—which are fillers and binders that help hold the capsule together.

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: promote healthy sugar metabolism and blood pressure.
  • We looked for evidence on: Diabetes, Dyslipidemia, Hypertension, Impaired glucose tolerance (prediabetes), Obesity, Metabolic syndrome — and 1 related terms.
  • 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, Hypertension, Obesity, Impaired glucose tolerance (prediabetes).

The evidence for cassia cinnamon is not established for the conditions listed in our data: amenorrhea, angina, common cold, diabetes, diarrhea, and dyslipidemia (abnormal cholesterol levels) all show insufficient reliable evidence to rate. That means the studies we have aren't strong enough to say whether it works for these uses.

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 in the amounts you'd eat in food. However, concentrated supplement doses raise some concerns.

Because cassia cinnamon contains coumarin, which can harm the liver in very high doses taken over a long time, the data advises against medicinal or high-dose supplement amounts during pregnancy. In clinical trials, a small number of participants reported a rash or, in one case, eyelid dermatitis after taking cinnamon.

In another instance, one participant experienced low blood sugar (hypoglycemia) severe enough to cause a seizure, though it's unclear whether the cinnamon caused it. Breastfeeding safety data isn't on file.

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 your exact medications if you take drugs that harm the liver (hepatotoxic drugs, Moderate interaction) or diabetes medications (Moderate interaction). These are the two drug categories with documented interactions in our data for this product.

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 medications or drugs that affect your liver, check with us or your doctor before starting CinnaMedic Cinnamon—the dose and duration matter. It's generally well tolerated at food amounts, but long-term high-dose supplement use isn't well studied.

Talk to your pharmacist before adding it to your routine.

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.

CinnaMedic Cinnamon by Wonder Laboratories: Common Questions

Does CinnaMedic Cinnamon by Wonder Laboratories interact with any medications?
Yes. Based on its ingredients, CinnaMedic Cinnamon 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?
CinnaMedic 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 cinnamon help my blood sugar?
The evidence isn't strong enough to say. Our data shows insufficient reliable evidence to rate cassia cinnamon for diabetes. If you're interested, talk with your doctor, and definitely check with us first if you're already on diabetes medication—cinnamon might lower your blood sugar further.
Is it safe to take this if I'm pregnant?
Food amounts of cinnamon are likely fine. But the safety data advises against medicinal or high-dose supplement amounts during pregnancy. If you're pregnant and want to use this product, talk with your doctor or pharmacist first.
Are there any side effects?
In clinical trials, a small number of people reported a rash. In one case, someone with a known allergy to cinnamic alcohol (a compound in cinnamon) developed eyelid redness that cleared a few days after stopping cinnamon. One participant experienced a severe low blood sugar event, though it's unclear if cinnamon caused it.
Can cinnamon harm my liver?
Cassia cinnamon contains coumarin, which can stress the liver in very high doses taken for extended periods. Supplement doses (360 mg to 12 grams daily for 3 months) used in trials didn't significantly raise liver enzymes. Still, avoid very long-term high-dose use, and don't use this product if you take medications that already burden your liver without checking with us first.
What is Cinnulin PF?
It's a standardized extract of cassia cinnamon—a concentrated form designed to deliver consistent amounts of the cinnamon's compounds in each capsule.
