From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: cassia seed extract at a 10:1 concentration, delivering 450 mg per capsule. The extract comes from cassia cinnamon seeds.

The capsules also contain gelatin and water as inactive ingredients.

Does it work?

Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Not assessable

This is a single-ingredient Cassia Cinnamon product and its label doesn't state a use — see Cassia Cinnamon's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence we hold for cassia seed extract shows insufficient reliable evidence to rate its use for amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (abnormal blood lipids). That means the data supporting these uses hasn't been established in the studies we have on file.

If you're considering this product for a specific condition, talk with your pharmacist or doctor about what the current evidence actually shows.

The evidence, ingredient by ingredient Cassia Cinnamon

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Cassia seed extract is generally well tolerated in food amounts, but supplement doses—especially high-dose or long-term use—carry caution due to coumarin content. Very high doses of coumarin (50–7,000 mg per day) have caused liver damage in humans, which resolved after stopping.

In one clinical trial, a rash appeared in one person taking 1 gram daily for 90 days, and isolated cases of contact dermatitis have been reported in people with cinnamon sensitivity. During pregnancy and breastfeeding, food amounts of cassia cinnamon are likely safe, but avoid medicinal or concentrated supplement doses due to limited safety data.

A hypoglycemic seizure was reported in one patient taking 1 gram daily for 3 months, though it's unclear if the supplement caused it.

Side effects, ingredient by ingredient Cassia Cinnamon

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Cassia Cinnamon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 443 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before taking this product, check whether you use any diabetes medications (cassia cinnamon may lower blood sugar and could require dose adjustments) or drugs that can harm the liver (hepatotoxic drugs). These are the main medication types affected.

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.

Likelihood Possible Evidence B
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.

Cassia Seed 450 mg 10:1 Extract by TerraVita Premium Collection: Common Questions

Does Cassia Seed 450 mg 10:1 Extract by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Cassia Seed 450 mg 10:1 Extract has a known interaction with 442 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cassia Seed 450 mg 10:1 Extract contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this while pregnant or breastfeeding?
Food amounts of cassia cinnamon are likely safe during pregnancy and lactation, but avoid medicinal or high-dose supplement amounts like this one because there isn't enough safety data. Talk with your doctor or pharmacist for personalized advice.
What's the difference between a 10:1 extract and regular cassia seed powder?
A 10:1 extract means the product is concentrated—10 parts of the original plant material were reduced to 1 part. That's why 450 mg here delivers more active compounds than 450 mg of a regular powder would.
Does this product contain coumarin, and is that dangerous?
Yes, cassia cinnamon naturally contains coumarin. At food-level amounts it's not a concern, but supplement doses taken long-term could theoretically cause liver damage because coumarin can be hepatotoxic at very high levels. If you take this regularly or have liver issues, mention it to your pharmacist.
Will this help my diabetes or blood sugar?
Our data shows insufficient reliable evidence to rate cassia seed extract for diabetes. It may lower blood sugar, which is why it can interact with diabetes medications, but we can't say whether it effectively manages the condition. Ask your doctor or pharmacist whether it's right for your situation.
What are the side effects?
In clinical trials, side effects were rare. One person reported a rash while taking 1 gram daily for 90 days. A few cases of contact dermatitis have been reported in people with cinnamon sensitivity. If you develop a rash or have trouble with low blood sugar, stop and talk with your pharmacist.
