HelloPharmacist Scorecard of Cinnamon 2% Extract Powder by TerraVita Premium Collection
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 extract, specifically cassia cinnamon in powder form at a 2% concentration. There are no inactive ingredients listed.
Does it work?
Couldn't assess
The evidence we hold doesn't establish that cinnamon is effective for any of the conditions it's marketed for—including diabetes, high cholesterol (dyslipidemia), diarrhea, amenorrhea (missed periods), angina, or the common cold. All of these are rated as having insufficient reliable evidence in our data.
That doesn't mean it doesn't work; it means the studies available to us haven't proven it yet.
How safe is it?
Well-documented data
Cinnamon is generally well tolerated at food amounts. However, as a concentrated supplement at higher doses, especially over time, it poses a liver-safety concern because of its coumarin content.
In clinical trials at doses ranging from 360 mg to 12 grams daily for up to 3 months, liver enzyme changes weren't significant, but very high doses of coumarin (50–7000 mg per day from any source) can cause liver damage that reverses when you stop. Rarely, rash or allergic skin reactions have been reported, and one case of low blood sugar (hypoglycemia) seizure was noted, though it's unclear if the cinnamon caused it.
Meds to double-check
Moderate interaction found
Double-check this product with your pharmacist if you take hepatotoxic drugs (medications that can stress the liver) or antidiabetes drugs (blood-sugar-lowering medications). Both interactions are rated Moderate severity.
At high doses or long-term use, the coumarin in cassia cinnamon could theoretically add to liver stress from other medications.
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.
If you take medications for your liver or blood sugar, talk to your pharmacist before starting this supplement—especially at higher doses or long-term use. Food amounts of cinnamon are safe; concentrated supplement doses are a different story.
Cinnamon is likely safe in pregnancy and breastfeeding at normal food levels, but avoid medicinal-dose supplements during those times.

HelloPharmacist Interaction Report
TerraVita Premium Collection Cinnamon 2% Extract Powder contains one active ingredient—cassia cinnamon—which has documented interactions with two main categories of medications.
Read the full breakdown — every affected drug type, severity by severity
The most serious concern is with hepatotoxic drugs (medications that can stress the liver). In theory, large doses of cassia cinnamon might add to that effect, since cassia cinnamon contains coumarin, a compound that can harm the liver when taken in very high amounts for a long time.
This interaction is rated Moderate severity.
Cassia cinnamon may also lower blood sugar levels, which means it could have additive effects with antidiabetes drugs (blood-sugar-lowering medications). If you're on any diabetes medication, your dose might need adjusting.
This is also rated Moderate severity. Altogether, these interactions span 425 individual medications.
Before you start this supplement, check your exact medications with the tool on this page—especially if you take drugs for your liver, blood sugar, or any condition affecting liver function.

Cinnamon Extract, Powder
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.
