HelloPharmacist Scorecard of Cinnamon Formula 1000 mg by Longevity Premier

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 3 active ingredients.
  • “Cinnamon Glucose Formula” is a proprietary blend — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

This product contains three active ingredients: bitter melon extract, Ceylon cinnamon extract, and a proprietary herbal blend. Bitter melon extract is traditionally used in herbal medicine, while Ceylon cinnamon extract is included as a concentrated form of cinnamon.

The product also contains cellulose, an inactive ingredient used as a filler.

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: blood sugar support and digestive health.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Dyspepsia, Dyslipidemia, Metabolic syndrome, glucose metabolism — and 1 related terms.
  • The closest evidence on file: Bitter Melon is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Bitter Melon is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia, Impaired glucose tolerance (prediabetes), Metabolic syndrome.
  • Also on file: Cassia Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Diabetes, Dyslipidemia, Impaired glucose tolerance (prediabetes).

The evidence for this product's effectiveness isn't established in the data we hold. Bitter melon has insufficient reliable evidence to rate for amenorrhea, athletic performance, liver disease, constipation, diabetes, and dyspepsia.

Ceylon cinnamon extract also has insufficient reliable evidence for amenorrhea, angina, common cold, diabetes, diarrhea, and dyslipidemia. We can't speak to how well this formula works for its intended purpose based on current clinical evidence.

The evidence, ingredient by ingredient Cassia Cinnamon Bitter Melon

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.

Bitter melon is generally well tolerated when taken in supplement doses, though some people report gastrointestinal side effects like nausea, vomiting, diarrhea, constipation, heartburn, and abdominal discomfort — occurring in about 3% to 16% of trial participants. Rare serious effects include hypoglycemic coma and seizures in children.

Ceylon cinnamon is generally safe at food amounts, but at high supplement doses there's concern about liver stress from its coumarin content. A rash and contact dermatitis have been reported in rare cases.

Regarding pregnancy: bitter melon is traditionally avoided because seeds and high doses may cause uterine or other harmful effects. Ceylon cinnamon is likely safe at food amounts but best avoided at medicinal doses during pregnancy.

There isn't enough reliable safety information for bitter melon while breastfeeding; talk with your doctor or pharmacist before use.

Side effects, ingredient by ingredient Cassia Cinnamon Bitter Melon

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 — Bitter Melon, Cassia Cinnamon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 586 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 with your pharmacist if you take antidiabetes drugs (bitter melon and cinnamon both lower blood sugar and could cause dangerously low levels), hepatotoxic drugs (cinnamon may add to liver stress), P-glycoprotein substrates (bitter melon may increase their levels), or pazopanib (a cancer drug that bitter melon may interfere with).

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product isn't for you if you take diabetes medications or pazopanib without discussing it first with your pharmacist — the blood sugar interactions are real. It's also not ideal if you're taking medications that stress the liver or depend on P-glycoprotein absorption.

If you're pregnant or breastfeeding, check with your doctor before starting. For anyone else considering it, have a pharmacist review your exact medication list.

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.

Cinnamon Formula 1000 mg by Longevity Premier: Common Questions

Does Cinnamon Formula 1000 mg by Longevity Premier interact with any medications?
Yes. Based on its ingredients, Cinnamon Formula 1000 mg has a known interaction with 585 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Cinnamon Formula 1000 mg 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.
Will this product lower my blood sugar?
Both bitter melon and cinnamon can lower blood glucose levels. If you take diabetes medications, this becomes a serious concern — combined effects could drop your blood sugar too low. Talk with your pharmacist before starting, especially if your diabetes is currently well controlled.
What are the most common side effects I might notice?
Bitter melon causes the most reported side effects, mostly gastrointestinal. You might experience nausea, vomiting, diarrhea, constipation, heartburn, flatulence, or stomach discomfort — these show up in about 3% to 16% of people taking it. Dizziness, fatigue, and headaches also happen occasionally.
Is this safe to take while pregnant?
The safety data advises against bitter melon in pregnancy because seeds and high doses may cause uterine or other harmful effects. Ceylon cinnamon is likely safe at food amounts but best avoided at medicinal supplement doses during pregnancy. Talk with your doctor or pharmacist for personalized advice.
Can I take this while breastfeeding?
There isn't enough reliable safety information on bitter melon for breastfeeding, so it's best avoided. Ceylon cinnamon has similar limitations at concentrated supplement doses. Discuss this with your doctor or pharmacist before starting.
What's in the proprietary herbal blend?
The product label lists it as a proprietary blend, which means the specific herbs and their amounts aren't disclosed individually. We don't hold interaction data for it, so we can't tell you whether it interacts with your medications — run this product through our checker with your exact drug list.
Could this hurt my liver?
Ceylon cinnamon contains coumarin, which can stress the liver at very high doses taken for extended periods. The cinnamon dose in this product is moderate, but if you're taking other medications that affect the liver or you have liver disease, mention this product to your pharmacist before starting.
