HelloPharmacist Scorecard of Ceylon Cinnamon 1,200 mg by Spring Valley

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: Ceylon cinnamon powder at 1,200 mg per capsule. The other ingredients — tapioca starch and purified water — are inert fillers and capsule material that help deliver the cinnamon.

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: Metabolism support, heart health and blood sugar.
  • 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 isn't established for the conditions we checked — amenorrhea, angina, common cold, diabetes, diarrhea, and high cholesterol all show insufficient reliable evidence in our data. That doesn't mean it doesn't work; it means the studies so far haven't been strong enough to draw firm conclusions.

If you're considering this for a specific health goal, talk with your pharmacist or doctor about what the current research 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.

Ceylon cinnamon (cassia cinnamon) is generally well tolerated in food amounts, but this supplement dose — 1,200 mg — is much higher. The main safety concern is coumarin, a compound in cassia cinnamon that can harm the liver with long-term use at high doses.

In clinical trials, doses of 360 mg to 12 grams daily for up to 3 months didn't significantly raise liver enzymes, but coumarin at very high intakes (50–7,000 mg daily) can cause liver damage that reverses when you stop. In rare cases, people have reported a rash or allergic skin reactions to cinnamon.

One patient had a low-blood-sugar seizure (hypoglycemic seizure) while taking 1 gram of cassia cinnamon daily, though it's unclear if the cinnamon caused it. During pregnancy, food amounts of cinnamon are likely fine, but avoid medicinal or high-dose supplement amounts — there isn't enough data.

Similarly, during breastfeeding, food amounts are probably okay, but concentrated supplement doses aren't well studied.

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 exact medications against two categories before taking this product: diabetes drugs (because cinnamon may lower blood sugar further), and medications that stress the liver. If you're on any drug that your pharmacist has flagged as hard on your liver, mention this supplement — the dose here is relatively high.

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're taking diabetes medications or drugs that can stress your liver, check with your pharmacist before starting this supplement — the dose is substantial and interactions are documented. For everyone else, the main risk is liver damage from long-term high-dose use, which is uncommon but possible.

Your liver and blood sugar are worth a quick conversation with your pharmacist.

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.

Ceylon Cinnamon 1,200 mg by Spring Valley: Common Questions

Does Ceylon Cinnamon 1,200 mg by Spring Valley interact with any medications?
Yes. Based on its ingredients, Ceylon Cinnamon 1,200 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?
Ceylon Cinnamon 1,200 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 cassia cinnamon actually work for blood sugar or cholesterol?
The evidence isn't clear yet. Studies on cassia cinnamon for diabetes, cholesterol, and other conditions we checked haven't produced reliable results so far — that's why the data shows insufficient evidence. It doesn't prove it doesn't work, but it means you shouldn't expect strong benefits based on current research.
Is 1,200 mg per capsule a high dose?
Yes, that's on the upper end of doses used in clinical trials. Most research has tested 360 mg to 12 grams daily, so this single capsule puts you near the middle-to-high range. That's partly why the liver and blood-sugar interactions matter — it's a meaningful amount.
Can I take this while pregnant or nursing?
Food amounts of cinnamon are likely fine during both pregnancy and breastfeeding, but medicinal or high-dose supplement amounts — like this 1,200 mg capsule — don't have enough safety data. Talk with your doctor or pharmacist if you're planning to take this during pregnancy or while nursing.
What's coumarin, and should I worry about it?
Coumarin is a natural compound in cassia cinnamon that can harm the liver if you take very large amounts over a long time. Your liver can handle it at normal food levels, but supplement doses at this strength are worth monitoring — if you have liver disease or take liver-stressing drugs, mention it to your pharmacist.
Has anyone had side effects from this supplement in trials?
A few cases have been reported: one person got a rash after taking 1 gram daily for 90 days, and another had allergic skin reactions. One person also had a low-blood-sugar seizure, though it's not certain the cinnamon caused it. These are rare, but it's good to know what to watch for.
