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.

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 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 contains four active ingredients, all from cinnamon: a hydroethanolic extract and a supercritical extract of cassia cinnamon, and the same two extract types of Ceylon cinnamon. These are concentrated forms designed to deliver cinnamon's active compounds in supplement strength.

The product also contains inactive ingredients — extra-virgin olive oil, hypromellose (a capsule binder), organic yellow beeswax, and candelilla wax — that help form and preserve the capsule.

Does it work?

Couldn't assess
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

The label doesn't state a purpose we can grade — see each ingredient's own graded uses on its monograph instead.

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

The evidence for cinnamon's effectiveness on the conditions listed in our data is limited. For both cassia and Ceylon cinnamon, there isn't enough reliable evidence to rate effectiveness for amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (abnormal blood fats).

Ceylon cinnamon specifically is rated possibly ineffective for obesity and diabetes. If you're considering this product for a particular health goal, talk with your pharmacist about what the science actually shows.

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 extracts are generally well tolerated when taken orally, though bloating, indigestion (dyspepsia), and nausea can occur in some people. Allergic reactions — including rash, itching, and skin irritation — have been reported in a small number of trial participants and case reports, particularly in people with a sensitivity to cinnamaldehyde or cinnamic alcohol.

At food-spice doses cinnamon is considered likely safe in pregnancy and lactation, but at higher supplement doses the safety data is thinner. The data notes that very high coumarin doses from cassia cinnamon (the compound present in that form) can stress the liver over time, though clinical trials at supplement doses haven't shown significant liver enzyme changes.

Side effects, ingredient by ingredient Cassia Cinnamon Ceylon 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?
  • 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.

Before taking this product, double-check if you're on blood pressure medications (antihypertensive drugs) — Ceylon cinnamon may lower your pressure further. If you take diabetes medications (antidiabetes drugs), your blood sugar might drop more than expected.

And if you're on any drugs that stress your liver (hepatotoxic drugs), the cassia cinnamon extracts could theoretically add to that burden at high doses. Your pharmacist can review your exact medications using the tool on this page.

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.

Cinnamon Force is generally well tolerated at typical doses. If you take blood pressure or diabetes medications, or drugs that affect your liver, check with your pharmacist before starting — dose adjustments might be needed.

If you have a known sensitivity to cinnamon or its compounds, skip it. For everyone else, talk with your pharmacist about whether the evidence supports using it for your specific goal.

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.

Likelihood Possible Evidence D

Ceylon Cinnamon2 drug types · 258 drugs

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.
Is this safe to take if I'm pregnant or breastfeeding?
Food amounts of cinnamon are generally safe, but at supplement doses the data is limited. The facts note that Ceylon cinnamon at supplement strength is rated likely safe in pregnancy and lactation, though the safety of higher doses while breastfeeding isn't well studied. Talk with your doctor or pharmacist for personalized advice.
What are the most common side effects I might notice?
Ceylon cinnamon is generally well tolerated, but some people report bloating, indigestion, or nausea. Allergic reactions like rash or itching are uncommon but have been reported, especially in people sensitive to cinnamon compounds. If you develop a rash or itching, stop and let your pharmacist know.
Can this help with diabetes?
The evidence isn't clear enough to say. Ceylon cinnamon is rated possibly ineffective for diabetes in our data, and cassia cinnamon doesn't have enough reliable evidence to rate. What we do know is that cinnamon may lower blood sugar, so if you do take it with diabetes medications you'll need your doctor to monitor you.
What's the difference between cassia and Ceylon cinnamon in this product?
This product contains both. Cassia cinnamon is higher in coumarin (a compound that can stress the liver at very high doses), while Ceylon is lower in coumarin but may affect blood pressure. Both types are present as concentrated extracts in this capsule.
How long can I safely take this product?
The data shows cinnamon is generally well tolerated at supplement doses taken for up to 3 months in clinical trials, with no significant liver enzyme changes. For longer use, the data is limited. Talk with your pharmacist about how long you plan to take it and whether monitoring makes sense.
Will this interact with blood thinners?
A case report describes one person on Ceylon cinnamon who had postoperative bleeding, though the exact cause is unclear. The formal interaction data we hold doesn't list blood thinners as a documented interaction category, but the report is worth flagging — mention cinnamon to your doctor if you take anticoagulants or antiplatelet drugs.
