HelloPharmacist Scorecard of Cinnamon Bark Capsules Bontanical Extract by Dee Cee Laboratories
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: cinnamon (from cassia cinnamon). The capsule is filled with 100% cinnamon — no other active or inactive filler ingredients are listed.
Does it work?
Not established
The evidence for cinnamon is not established in our data. We hold insufficient reliable evidence to rate its use for amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (abnormal cholesterol levels).
If you're considering this product for a specific condition, talk with your pharmacist about what the current research actually shows.
How safe is it?
Well-documented data
Cinnamon is generally well tolerated in food amounts. At supplement doses, especially high doses taken over a long time, there's concern about liver toxicity from the coumarin it contains.
The data advises against medicinal or high-dose supplement amounts during pregnancy, though food amounts are likely fine. Breastfeeding safety data is limited — stick to food amounts if you're nursing.
In clinical trials and case reports, a small number of people reported a rash, and one case involved systemic contact dermatitis (an allergic skin reaction that cleared within days of stopping cinnamon). One trial participant reported a low blood sugar seizure, though it's unclear if cinnamon caused it.
Meds to double-check
Moderate interaction found
Before taking this product, double-check your medications with the tool on this page — especially any drugs that can harm the liver (hepatotoxic drugs) and diabetes medications. These interactions are documented as Moderate severity, meaning dose adjustments or closer monitoring may be needed.
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.
Cinnamon capsules might be worth considering if you've talked with your doctor about using them alongside diabetes or liver-protective treatment — but this product needs a check against your exact medications first. If you take drugs that affect your liver or blood sugar, run them through our tool on this page before you start.

Cinnamon Bark Capsules Bontanical Extract by Dee Cee Laboratories Drug Interactions
HelloPharmacist Interaction Report
Cinnamon Bark Capsules Botanical Extract by Dee Cee Laboratories contains one active ingredient — cinnamon — which 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 can harm the liver (hepatotoxic drugs). In theory, large doses of cassia cinnamon might add to that liver stress over time.
Cassia cinnamon contains coumarin, a compound that's shown liver toxicity in animal studies. In humans, very high doses of coumarin (50–7,000 mg per day) have caused liver damage that reversed once the coumarin stopped, but clinical trials using cinnamon doses of 360 mg to 12 grams daily for three months did not significantly raise liver enzyme levels.
Cinnamon may also lower blood sugar (glucose). If you take diabetes medications, cassia cinnamon might add to that effect, and your doctor might need to adjust your medication dose.
Additionally, we hold no interaction data on the inactive ingredient listed. Use the medication checker on this page to look up your exact drugs before you start.

Cinnamon
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.
