HelloPharmacist Scorecard of Cinnamon Bark by Gaia Herbs
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.
What’s inside
Low disclosure
This product contains two active ingredients — organic cinnamon bark extract and organic cinnamon bark supercritical CO2 extract — both from cassia cinnamon. The inactive ingredients are vegetable glycerin, sunflower lecithin, water, and a vegan capsule.
Does it work?
Couldn't assess
The evidence for cassia cinnamon is not established in the data we hold. The product lists six conditions — amenorrhea, angina, common cold, diabetes, diarrhea, and dyslipidemia — but all carry a rating of insufficient reliable evidence.
That means we don't yet have strong enough research to say whether it works for these uses.
How safe is it?
Well-documented data
Food amounts of cinnamon are generally well tolerated. At supplement doses, though, there's concern about coumarin — a compound in cassia cinnamon that can harm the liver if you take large amounts for a long time.
In clinical trials, one person on 1 gram daily for 90 days developed a rash, and one person on the same dose for 3 months reported a low blood sugar event (though it's unclear if cinnamon caused it). There's also been a case of contact dermatitis in someone with a cinnamon allergy.
For pregnancy, food amounts are likely fine, but avoid medicinal or high-dose supplement amounts — the safety data isn't complete enough. For breastfeeding, avoid concentrated supplement doses due to limited safety information.
Meds to double-check
Moderate interaction found
Double-check this before starting if you take diabetes medications — cinnamon may lower blood sugar and could require dose adjustments. Also check if you're on any drug that's hard on the liver (hepatotoxic), since long-term, high-dose cinnamon is theoretically a concern there too.
The bottom line
Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.
If you're taking diabetes medication or drugs that stress your liver, talk with your pharmacist before starting this product. The cinnamon extract may lower blood sugar or add to liver strain at higher doses.
Food amounts are much safer than supplements, and you should check your exact medications against our interaction tool.

Cinnamon Bark by Gaia Herbs Drug Interactions
HelloPharmacist Interaction Report
Cinnamon Bark by Gaia Herbs contains two forms of cinnamon extract, both derived from cassia cinnamon.
This product has documented interactions with two categories of medications.
Read the full breakdown — every affected drug type, severity by severity
The most serious concern is with drugs that stress the liver (hepatotoxic drugs). Large doses of cassia cinnamon taken over time might add to that liver stress due to its coumarin content — a compound that can damage the liver in animal studies.
In humans, very high doses of coumarin (50–7,000 mg daily) have caused liver damage that improved once the coumarin stopped. Clinical trials using cinnamon at 360 mg to 12 grams daily for 3 months didn't significantly raise liver enzyme levels, but the safety data still cautions against high-dose, long-term use.
The second interaction is with diabetes medications (antidiabetes drugs). Cassia cinnamon may lower blood sugar (glucose), which could add to the effect of your diabetes medication.
If you take a drug to manage blood sugar, dose adjustments might be needed.
Altogether, these interactions span 425 individual medications. Check your exact medications with the tool on this page before you start.

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.
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.
