HelloPharmacist Scorecard of Cinnamon Bark 1000 mg by AN Amazing Nutrition Amazing Formulas

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: cinnamon (from cassia cinnamon), at 1000 mg per capsule. Cassia cinnamon is a spice commonly used in cooking, but at supplement doses it's a much more concentrated form.

The capsule also contains three inactive ingredients — vegetable cellulose (the capsule itself), magnesium stearate, and silicon dioxide — which are standard fillers and binders used to 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: antioxidant anti-inflammatory immunity cardiovascular support.
  • We looked for evidence on: Dyslipidemia, Hypertension, Diabetes, Impaired glucose tolerance (prediabetes), Oxidative stress, Inflammatory markers.
  • 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, Impaired glucose tolerance (prediabetes).

The evidence for cinnamon's effectiveness is not established in the data we hold. The facts list six conditions — amenorrhea, angina, common cold, diabetes, diarrhea, and high cholesterol — but all carry a rating of insufficient reliable evidence.

That means the research so far isn't solid enough to say whether it works for any of them. If you're considering this for a specific health reason, talk to your pharmacist or doctor about what the current science actually supports.

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 at food amounts — the sprinkle on your oatmeal is fine. At supplement doses like this one, though, there are a few things to watch.

The main concern is liver damage from coumarin, especially with long-term use. In clinical trials, doses ranging from 360 mg up to 12 grams daily for three months didn't significantly raise liver enzymes, but very high coumarin doses in other studies have caused liver problems that improved when the supplement was stopped.

Side effects are rare. A rash was reported in one person taking 1 gram daily, and there's one case report of contact dermatitis in someone with a cinnamon allergy.

One hypoglycemic seizure (low blood sugar seizure) was reported in a trial, though it's unclear if cinnamon caused it. During pregnancy and breastfeeding, food amounts are likely fine, but avoid high-dose supplements — the safety data just isn't there.

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 taking this product, double-check with your pharmacist if you're on drugs that stress the liver (hepatotoxic drugs) or diabetes medications. Both interactions are moderate-severity and may require dose adjustments to your prescription.

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.

This is a straightforward cinnamon supplement if you're curious about it, but the evidence for most health claims is thin. If you take diabetes medications or any drug that stresses your liver, check with your pharmacist first — the interactions are real.

Otherwise, talk to your doctor or pharmacist before starting, especially if you plan to take it long-term.

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 Bark 1000 mg by AN Amazing Nutrition Amazing Formulas: Common Questions

Does Cinnamon Bark 1000 mg by AN Amazing Nutrition Amazing Formulas interact with any medications?
Yes. Based on its ingredients, Cinnamon Bark 1000 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 Bark 1000 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 work for blood sugar or cholesterol?
The facts don't show enough solid evidence to say yes. All the major uses listed — diabetes, cholesterol, and several others — have a rating of insufficient reliable evidence. That means research hasn't been rigorous enough yet to confirm whether it works.
Is this safe to take every day?
At food amounts, yes. At supplement doses like 1000 mg daily, the main worry is coumarin in the cinnamon, which can harm the liver over time — especially if you take it for months. Clinical trials at up to 12 grams daily for three months didn't spike liver enzymes, but very high coumarin doses in other studies did cause liver damage. If you plan to take this regularly, mention it to your doctor or pharmacist.
Can I take this while pregnant or breastfeeding?
Food amounts are likely fine. High-dose supplements like this one — avoid them, because there isn't enough safety data. Talk to your doctor or pharmacist for personalized advice based on your situation.
What are the side effects?
They're uncommon. One person reported a rash at 1 gram daily, and there are case reports of contact dermatitis in people allergic to cinnamon. One person had a low blood sugar seizure in a trial, though it's not clear cinnamon caused it.
What's the difference between this and the cinnamon I cook with?
This is the same spice, but much more concentrated — 1000 mg of pure cinnamon powder in a capsule versus a pinch in food. At that dose, especially taken daily for months, the liver concerns become real, whereas a sprinkle of cinnamon on your breakfast is safe.
