HelloPharmacist Scorecard of Cinnamon Bark Capsules by Wonder Labs
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 bark extract. The capsule itself is made from 100% pure cinnamon with no other added fillers or binders.
Does it work?
Couldn't assess
The evidence supporting cinnamon bark for its claimed uses isn't established in our data. We hold insufficient reliable evidence to rate it for amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (high cholesterol and triglycerides).
That doesn't mean it doesn't work—it means the studies aren't strong enough yet to say one way or the other.
How safe is it?
Well-documented data
Cinnamon is generally well tolerated in food amounts. At supplement doses, especially high ones taken for a long time, there's concern about liver damage from its coumarin content—though in clinical trials, doses up to 12 grams daily for 3 months didn't significantly raise liver enzymes in the people studied.
A small number of trial participants reported a rash, and isolated case reports describe contact dermatitis in people with cinnamon allergies. One patient in a trial experienced a low blood sugar seizure (hypoglycemia), though it's unclear whether cinnamon caused it.
During pregnancy and breastfeeding, food amounts of cinnamon are likely safe, but avoid high-dose supplements due to limited safety data.
Meds to double-check
Moderate interaction found
Before taking this product, double-check any hepatotoxic drugs (drugs that can harm the liver) and antidiabetes medications (blood sugar drugs) with your pharmacist. Cinnamon may lower blood glucose and could theoretically add to liver stress at high doses, so your prescriber may need to adjust your medication.
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 single-ingredient cinnamon supplement is generally well tolerated at typical doses. If you take medication for diabetes or have liver disease, check your exact drugs with our tool before starting—cinnamon can lower blood sugar and theoretically stress the liver at high doses.
Talk to your pharmacist if you have questions about your personal situation.

Cinnamon Bark Capsules by Wonder Labs Drug Interactions
HelloPharmacist Interaction Report
Cinnamon Bark Capsules by Wonder Labs contains one active ingredient—cinnamon bark extract—that interacts with medications in two important ways.
The most serious concern involves hepatotoxic drugs (drugs that can stress or damage the liver). Theoretically, large doses of this cinnamon over a long time might add to that liver stress, especially because cinnamon contains coumarin, a compound that has caused liver damage in animal studies.
In humans, very high doses of coumarin—well above what's in typical supplements—have caused reversible liver damage.
Read the full breakdown — every affected drug type, severity by severity
The second interaction affects antidiabetes drugs (medications for blood sugar control). Cinnamon may lower blood glucose on its own, so it could have additive effects when combined with diabetes medications.
Your doctor might need to adjust your diabetes drug dose if you start taking this supplement.
Altogether, these interactions span 425 individual medications. If you take any prescription medication—especially for liver disease or diabetes—use the interaction checker on this page to look up your exact drugs before you start.

For each ingredient in Cinnamon Bark Capsules 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.
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.
