HelloPharmacist Scorecard of Ceylon Cinnamon Bark Extract Powder 1000 mg by BulkSupplements.com
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
Full disclosure
This product contains one active ingredient: Ceylon Cinnamon Bark Extract at 1000 mg per serving. Cinnamon bark extract is a concentrated form of the spice, stripped down to its active compounds.
The only other ingredient listed is dextrin, an inactive filler used in the powder.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that this cinnamon extract is effective for any of the conditions studied — amenorrhea, angina, common cold, diabetes, diarrhea, and unhealthy cholesterol levels all show insufficient reliable evidence to rate it. That doesn't mean it doesn't work; it means the science isn't settled enough yet to say one way or the other.
How safe is it?
Well-documented data
Cinnamon in food amounts is generally well tolerated. At supplement doses — especially high doses or long-term use — there's a concern about liver harm.
This extract contains coumarin, a compound that can damage the liver in very high amounts or over extended time. In clinical trials, cinnamon doses of 360 mg to 12 grams daily for 3 months didn't significantly change liver tests, but caution is still warranted with long-term use.
A small number of trial participants reported a rash or, in one case, low blood sugar (hypoglycemia) with a seizure, though it's unclear whether cinnamon caused that seizure. During pregnancy and breastfeeding, food amounts are fine, but avoid this supplement at medicinal or high-dose amounts — there isn't enough safety data to be certain.
Meds to double-check
Moderate interaction found
Check your exact medications if you take antidiabetes drugs (blood sugar control) or hepatotoxic drugs (any drug known to affect the liver) — both have Moderate interactions with this extract. Your pharmacist can help you decide if it's safe for your specific situation and whether your medication doses need adjustment.
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.
This product is worth considering if you're looking for a cinnamon supplement and have no liver conditions or diabetes. If you take diabetes medications or any drug that can stress the liver, check with your pharmacist first — dose adjustments to your medications might be needed, and long-term use at supplement levels carries liver concerns.

HelloPharmacist Interaction Report
Ceylon Cinnamon Bark Extract by BulkSupplements.com does interact with medications.
The main concern is with drugs that affect the liver (hepatotoxic drugs). In large doses, this cinnamon extract might add to the liver stress these drugs already cause, raising the risk of liver damage over time — a Moderate severity interaction.
Read the full breakdown — every affected drug type, severity by severity
It also has a Moderate interaction with diabetes medications. Ceylon cinnamon may lower blood sugar on its own, so combining it with diabetes drugs could push your blood sugar too low.
Your diabetes medication doses might need adjusting if you add this supplement.
Each of these interactions depends on dose and duration — the risks are higher with supplement-level amounts taken long-term rather than small amounts of cinnamon in food. If you take any medications for diabetes or liver conditions, or any drug known to stress the liver, run them through the checker below before starting this product.
Altogether, these interactions span 443 individual medications.

For each ingredient in Ceylon Cinnamon Bark Extract Powder 1000 mg with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.
Ceylon Cinnamon Bark Extract
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.
