HelloPharmacist Scorecard of Cinnamon Force by New Chapter

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
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 4 of its 4 active ingredients.
  • “Cinnamon” is listed as a grouped ingredient — the label gives one combined amount (105 mg) without saying how much of each component you get.
  • “Ceylon Cinnamon” is listed as a grouped ingredient — the label gives one combined amount (35 mg) without saying how much of each component you get.

Cinnamon Force has 4 active ingredients: a cinnamon blend, Ceylon cinnamon, a cinnamon hydroethanolic extract (from Cassia Cinnamon), and a cinnamon supercritical extract (from Ceylon Cinnamon). These work as concentrated forms of cinnamon to deliver its traditional compounds.

The product also contains inactive ingredients — extra-virgin olive oil, hypromellose, organic yellow beeswax, candelilla wax, maltodextrin, and gum acacia — that serve as the capsule structure and binders.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use.

Why this rating?
  • The label markets this product for: help retain healthy blood sugar levels.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Dyslipidemia, Postprandial glucose control, Glycemic response.
  • The closest evidence on file: Ceylon Cinnamon is rated "Possibly Ineffective" for Diabetes (Natural Medicines).
  • Also on file: Ceylon Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Impaired glucose tolerance (prediabetes).
  • Also on file: Cassia Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Diabetes, Dyslipidemia, Impaired glucose tolerance (prediabetes).

The evidence for what cinnamon actually does isn't established in our data. For the cassia cinnamon extracts, we have insufficient reliable evidence to rate their use for amenorrhea, angina, the common cold, diabetes, diarrhea, and dyslipidemia (high cholesterol).

For the Ceylon cinnamon extracts, the evidence suggests they may be ineffective for obesity and diabetes, and there's insufficient evidence for hay fever, COPD, and the common cold.

The evidence, ingredient by ingredient Cassia Cinnamon Ceylon 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Ceylon cinnamon is generally well tolerated, with uncommon adverse reactions. The most common side effects reported with oral use are bloating, indigestion (dyspepsia), and nausea.

Cinnamon can occasionally trigger allergic skin reactions, including rashes and dermatitis, especially in people already sensitive to cinnamon compounds. One case report describes significant bleeding in a patient who took Ceylon cinnamon daily for 10 months before surgery.

Because cassia cinnamon extracts contain coumarin, which can harm the liver at very high doses over time, be cautious with long-term use of supplement-strength amounts — food amounts are likely fine. For Ceylon cinnamon, food amounts are considered likely safe in pregnancy, though medicinal doses should be avoided; supplement doses during breastfeeding are less studied.

Speak with your doctor or pharmacist before using this product if you're pregnant or nursing.

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?
  • 2 of the 2 matched ingredients can interact with medications — Ceylon Cinnamon, Cassia Cinnamon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 600 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.

Check your medications before starting if you take drugs to lower blood sugar (antidiabetes drugs) — your dose may need adjustment. If you're on blood pressure medication, mention this product to your pharmacist, as it may add to its effect.

If you take anything that can harm the liver or are considering very long-term use, discuss it first.

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 Force is worth considering if you're interested in cinnamon's traditional benefits, but talk to your pharmacist first if you take diabetes medications, blood pressure drugs, or anything that can affect your liver. The evidence for what it actually accomplishes isn't clear.

If you're pregnant, nursing, or plan long-term use, check with your doctor or pharmacist.

Cinnamon2 drug types · 442 drugs

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.

Antidiabetes Drugs

Theoretically, Ceylon cinnamon may have additive effects with antidiabetes drugs.
Ceylon cinnamon may lower blood glucose levels. Dose adjustments might be necessary.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, Ceylon cinnamon might have additive effects with antihypertensive drugs and increase the risk of hypotension.
Animal research shows that Ceylon cinnamon extract has vasorelaxant properties and reduces blood pressure in rat models of hypertension, possibly via inhibition of calcium influx through L-type voltage-sensitive channels.

Cinnamon Force by New Chapter: Common Questions

Does Cinnamon Force by New Chapter interact with any medications?
Yes. Based on its ingredients, Cinnamon Force has a known interaction with 599 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cinnamon Force contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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.
Will this affect my diabetes medication?
Yes, possibly. The cinnamon extracts in this product may lower blood glucose levels, so they could add to what your diabetes drug does. Talk to your doctor or pharmacist — you might need a dose adjustment to your medication.
Is it safe to take this while pregnant or breastfeeding?
Food amounts of cinnamon are likely safe in pregnancy, but we don't have enough data on supplement-strength doses during pregnancy or breastfeeding. Talk to your doctor or pharmacist for advice tailored to your situation.
What side effects has cinnamon caused in trials?
The most common ones are bloating, indigestion, and nausea. Allergic skin reactions like rashes have been reported in a small number of trial participants. One case report describes bleeding after long-term use, though that's rare.
Can cinnamon hurt my liver?
There's a theoretical concern with very high doses of cassia cinnamon over extended time, since it contains coumarin, which can harm the liver in animal studies. Food amounts are considered safe, but if you plan long-term supplement use, check with your doctor.
Does this product actually work for diabetes or weight loss?
The evidence we have suggests cinnamon may be ineffective for obesity and diabetes. For other uses like the common cold or high cholesterol, there isn't enough reliable evidence to say.
What's the difference between the two types of cinnamon in this product?
Cinnamon Force contains both cassia cinnamon and Ceylon cinnamon extracts. Ceylon cinnamon is generally well tolerated with uncommon side effects, while cassia cinnamon carries a higher coumarin content, which is why long-term use raises more caution about liver effects.
