HelloPharmacist Scorecard of Cinnamon by Banyan Botanicals

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 is pure cinnamon powder—one active ingredient. It's cassia cinnamon, the type you're probably familiar with from cooking.

There are no added fillers or other inactive ingredients in this product.

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 doesn't establish that cinnamon is effective for any of the conditions it's marketed for—amenorrhea, angina, common cold, diabetes, diarrhea, or high cholesterol (dyslipidemia). All of those conditions have insufficient reliable evidence to rate its usefulness.

That doesn't mean it doesn't work; it means the data we have isn't strong enough to say one way or the other.

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 ones over weeks or months—there's a caution about liver harm from coumarin.

In trials, a small number of people reported a rash, and one case of contact dermatitis has been documented in someone with a known cinnamic alcohol allergy. One trial participant also had a hypoglycemic seizure (low blood sugar), though it's unclear whether cinnamon caused it.

Avoid medicinal or high-dose supplement amounts during pregnancy; food amounts are likely fine. During breastfeeding, limited safety data exists for concentrated supplements, so stick to culinary amounts.

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 taking this cinnamon powder as a regular supplement, check whether you're on any drugs that can strain the liver (hepatotoxic drugs—your pharmacist can tell you which ones you take) or diabetes medications. Both are Moderate-severity concerns at supplement doses.

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.

Banyan Botanicals Cinnamon is food-grade cinnamon powder. If you use it occasionally in cooking, you're in the clear.

If you're thinking of taking it as a daily supplement—especially if you're on liver medications or diabetes drugs—talk to your pharmacist or doctor first. The evidence for its benefits isn't established yet.

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 by Banyan Botanicals: Common Questions

Does Cinnamon by Banyan Botanicals interact with any medications?
Yes. Based on its ingredients, 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?
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 this safe during pregnancy?
Food amounts—the little bit in cooking—are likely fine. But avoid taking cinnamon as a medicinal supplement or high-dose powder while pregnant. If you're thinking about supplementation, talk with your doctor or pharmacist for personalized advice.
Can cinnamon help with diabetes?
The evidence we hold on cinnamon for diabetes is insufficient—we don't have strong enough data to say whether it works. And since cinnamon can lower blood sugar, you'd need to talk with your doctor about dose adjustments to your diabetes medication if you do start taking it.
What's the difference between food amounts and supplement doses?
Culinary amounts—the sprinkle in your coffee or oatmeal—contain far less coumarin and are considered safe. Supplement powders like this one are concentrated, and taking them daily for weeks or months raises the risk of liver effects, especially in large amounts.
Are there any side effects?
A rash was reported in one person taking 1 gram daily for three months in a trial. One case of contact dermatitis occurred in someone allergic to cinnamic alcohol. A hypoglycemic seizure (low blood sugar) was reported once, but it's unclear if cinnamon caused it. Most people tolerate it well.
Is this pure cinnamon with nothing else added?
Yes—it's one ingredient, cinnamon powder, with no fillers or other inactive ingredients.
