HelloPharmacist Scorecard of Cinnamon 1000 mg by Solaray

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 product contains one active ingredient: cinnamon (specifically cassia cinnamon) at 1000 mg per capsule. The capsule itself is made from cellulose, an inactive ingredient.

Does it work?

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 the conditions listed — amenorrhea, angina, common cold, diabetes, diarrhea, and dyslipidemia (high blood fats) all show insufficient reliable evidence to rate. If you're considering cinnamon for any of these, talk with your pharmacist or doctor about whether the research supports its use for your situation.

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 from food is generally well tolerated. At supplement doses — especially high doses or over long periods — there's concern about liver damage from the coumarin it contains.

In clinical trials, doses from 360 mg to 12 grams daily for up to three months didn't cause significant changes in liver enzyme tests, but the caution remains for extended use. A small number of people have reported a rash, and there's one case of contact dermatitis in someone with a cinnamon allergy.

One trial participant taking 1 gram daily had a low blood sugar episode (hypoglycemia) with a seizure, though it's unclear if cinnamon caused it. During pregnancy and breastfeeding, food amounts of cinnamon are likely fine, but avoid medicinal or high-dose supplement amounts — there isn't enough safety data to know they're okay.

  • 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 you take this cinnamon supplement, check your medications against our tool below if you take drugs that affect the liver (hepatotoxic drugs) or diabetes medications. These are the two categories with documented interactions.

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 1000 mg by Solaray: Common Questions

Does Cinnamon 1000 mg by Solaray interact with any medications?
Yes. Based on its ingredients, Cinnamon 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 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.
Is cinnamon safe to take if I have diabetes?
Cinnamon may lower blood sugar on its own, so if you take diabetes medication, there's a Moderate interaction risk — the two could add up and lower your blood sugar too much. Your doctor might need to adjust your medication dose. Check with them or your pharmacist before starting.
Can this hurt my liver?
At food amounts, no. At supplement doses, there's concern because cinnamon contains coumarin, which can damage the liver if you take very high amounts for a long time. Clinical trials at 360 mg to 12 grams daily for three months didn't show liver enzyme changes, but the caution applies to extended use. If you have liver disease or take drugs that stress your liver, talk to your pharmacist first.
Is this safe during pregnancy?
Food amounts of cinnamon are likely fine. Medicinal or high-dose supplement amounts don't have enough safety data, so it's best to avoid them. Talk with your doctor or pharmacist about what's right for you.
Does cinnamon work for diabetes?
We hold insufficient reliable evidence to say whether it does. If you're considering it for blood sugar control, discuss that with your doctor — don't rely on it alone without medical guidance.
What's the one active ingredient in this?
Cassia cinnamon at 1000 mg per capsule. The capsule is made from cellulose, which is just an inactive filler.
