HelloPharmacist Scorecard of CinnaBoost by Garden Greens

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

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 2 active ingredients.
  • “CinnaBoost(TM)” is listed as a grouped ingredient — the label gives one combined amount (1,000 mg) without saying how much of each component you get.

CinnaBoost has 2 active ingredients: cinnamon extract and a standardized cinnamon extract. Both are forms of cassia cinnamon, which is the spice you know from cooking.

The product also contains inactive ingredients — cellulose, dicalcium phosphate, vegetable magnesium stearate, and silica — which are fillers and binders that help hold the capsule together.

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 — see Cassia Cinnamon's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: help support healthy blood sugar and metabolism.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Dyslipidemia, Obesity, metabolic health, glucose regulation.
  • The closest evidence on file: Cassia Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Cassia Cinnamon is rated "Insufficient Reliable Evidence To Rate" for Dyslipidemia, Obesity, Impaired glucose tolerance (prediabetes).

The evidence for cinnamon isn't established in the data we hold. We have no sufficient reliable evidence to rate it for amenorrhea, angina, common cold, diabetes, diarrhea, or dyslipidemia (high blood fats).

That doesn't mean it doesn't work — it means the studies aren't solid enough yet for us to say.

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.

Food amounts of cinnamon are generally well tolerated. At higher supplement doses, especially over a long time, there's concern about liver damage because of the coumarin in cassia cinnamon.

In clinical trials, people took 360 mg to 12 grams daily for up to 3 months without a significant increase in liver enzymes, but long-term safety at high doses isn't fully known. A small number of trial participants reported a rash or, in rare cases, skin reactions if they had a cinnamon allergy.

One person taking cinnamon also reported a low blood sugar event (hypoglycemia), though it's unclear if cinnamon caused it. During pregnancy and breastfeeding, food amounts appear likely safe, but you should avoid medicinal or high-dose supplement amounts — the data on those isn't solid enough.

Talk with your pharmacist or doctor if you're pregnant or nursing.

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.

Check with your pharmacist if you take diabetes medications (antidiabetes drugs) — cinnamon may lower your blood sugar and could require a dose adjustment. Also double-check if you take any medications that stress the liver (hepatotoxic drugs), since high-dose cinnamon over time could add to that burden.

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.

If you take diabetes medications or drugs that affect your liver, run this past your pharmacist first — cinnamon can lower blood sugar and theoretically add to liver stress at high doses. The product is generally well tolerated at typical supplement doses, but long-term safety at high doses isn't fully settled.

Food amounts are fine, but stick to what the label says.

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.

CinnaBoost by Garden Greens: Common Questions

Does CinnaBoost by Garden Greens interact with any medications?
Yes. Based on its ingredients, CinnaBoost 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?
CinnaBoost 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 I'm pregnant or breastfeeding?
Food amounts of cinnamon appear likely safe during pregnancy and breastfeeding, but we don't have enough safety data for medicinal or high-dose supplement amounts. Talk with your doctor or pharmacist for personalized advice before starting.
Will this help my diabetes or high blood sugar?
We don't have sufficient reliable evidence to say whether cinnamon works for diabetes. What we do know is that cinnamon may lower blood sugar, which is why you need to tell your pharmacist if you're on diabetes medications.
What's the difference between the two cinnamon ingredients in here?
Both are forms of cassia cinnamon extract — one is a straight extract, the other is standardized (meaning it's been adjusted to a consistent strength). They're the same spice in slightly different formats.
Can cinnamon really hurt my liver?
At very high doses (50–7,000 mg of coumarin per day), cinnamon's coumarin content can damage the liver in humans, but the damage reversed when people stopped. Food amounts and typical supplement doses are generally safe, but long-term use at high doses carries some risk.
What are the side effects I should watch for?
Most people tolerate cinnamon well. In trials, a small number reported a rash. If you have a cinnamon allergy, you could develop skin reactions. One person reported low blood sugar, though it's unclear if cinnamon was the cause. Stop taking it and call your pharmacist if you notice anything odd.
