HelloPharmacist Scorecard of Cinnamon 500 mg by Genceutic Naturals

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 2026

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: organic cinnamon (the cassia variety) at 500 mg per capsule. The capsule itself is made from natural pullulan polysaccharide, which is an inert ingredient that holds the powder 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.

The evidence we hold on file doesn't establish that cinnamon works for any condition. Six conditions have been studied — amenorrhea, angina, common cold, diabetes, diarrhea, and dyslipidemia (high cholesterol) — but in each case, the evidence is insufficient to rate its effectiveness.

That doesn't mean cinnamon doesn't work; it means the research so far isn't strong enough to make that call.

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.

Food amounts of cinnamon are generally well tolerated. At supplement doses — especially high doses over a long time — coumarin content becomes a concern because of potential liver harm.

Cassia cinnamon is likely safe in pregnancy and while breastfeeding at food amounts, but avoid medicinal or high-dose supplement amounts during pregnancy, and avoid concentrated supplement doses while nursing due to limited safety data. In rare cases, people have reported a rash or contact dermatitis from cinnamon, and one trial participant had a low blood sugar event (hypoglycemic seizure) while taking 1 gram daily, though it's unclear if cinnamon caused it.

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.

Check your list before starting if you take drugs that affect your liver (hepatotoxic drugs) or diabetes medications — cinnamon may amplify their effects. The interaction checker on this page can search your exact prescriptions.

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.

If you eat cinnamon as a spice, you're fine. If you're taking this 500 mg supplement, especially long-term, talk to your pharmacist first — particularly if you take diabetes or liver-affecting 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 500 mg by Genceutic Naturals: Common Questions

Does Cinnamon 500 mg by Genceutic Naturals interact with any medications?
Yes. Based on its ingredients, Cinnamon 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 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.
Does cinnamon actually help with diabetes or high cholesterol?
We don't have strong enough evidence on file to say. Cinnamon has been studied for both, but the research isn't conclusive either way. That doesn't mean it won't help you — just that we can't rate it yet based on the data we hold.
Is this safe to take every day?
Food amounts of cinnamon are generally well tolerated. At this 500 mg supplement dose, especially if you take it long-term, there's concern about coumarin content and potential liver harm. Talk to your pharmacist about how long you plan to take it and whether it's okay for your situation.
Can I take this while pregnant or breastfeeding?
Food amounts are likely fine, but medicinal or high-dose supplement amounts during pregnancy haven't been tested enough to know either way. While nursing, concentrated supplement doses also aren't well studied. Talk to your doctor or pharmacist for personalized advice.
What's in the capsule besides the cinnamon?
The capsule itself is made from natural pullulan polysaccharide, which is a binder that holds the powder together. There are no other active ingredients.
Can cinnamon cause side effects?
Most people tolerate it well. In rare cases, people have reported a rash or skin irritation. There's also one report of very low blood sugar in a trial participant, though it's unclear if cinnamon caused it. If you notice any unusual symptoms, stop and talk to your pharmacist.
