At a glance
- One ingredient: ground Ceylon cinnamon, the dried inner bark of Cinnamomum verum, in a 1.76 oz (50 g) glass jar.
- $6.29 on Amazon on Sep 30, 2026, shipped and sold by Amazon.com, which works out to about $3.57 per ounce.
- The jar prints three third-party seals (USDA Organic, Fairtrade and Regenerative Organic Certified, Bronze level). Ceylon is the milder, sweeter cinnamon; it is not the same bark as the cassia in most US supermarket jars.
What the label shows
We read the jar from the photos on the Amazon listing (front, both side panels and back) and from the listing text on September 30, 2026. The Amazon title is short ("Frontier Natural Products Cinnamon, 1.76 oz"), but the jar itself and the listing's bullet points identify it as Frontier Co-op's organic Ceylon cinnamon.
| Label item | What it says | What it means |
|---|---|---|
| Product name | Organic Ceylon Cinnamon | "Ceylon" is the old name for Sri Lanka and is the usual trade name for Cinnamomum verum, often called "true" cinnamon. |
| Net weight | 1.76 oz (50 g) | A standard spice-rack jar; ground cinnamon is light, so this is a fair amount by volume. |
| USDA Organic | Seal on the front and side | Grown and handled under the USDA organic rules. The back panel names the certifier as QAI. It says nothing about flavor strength or health. |
| Fairtrade | Fairtrade mark on the front and side | A social-and-trade certification of the supply chain, separate from the organic seal. |
| Regenerative Organic Certified | ROC logo, "Bronze" | A further farming-practice certification layered on top of organic; Bronze is the entry tier of that scheme. |
| Kosher | KSA symbol on the front | A kosher certification mark. |
| "Non-GMO" | Printed on a blue banner | A claim printed by the brand, not a separate third-party seal on this jar. |
| Nutrition or supplement panel | None shown in the listing photos | This is sold as a kitchen spice, with no Supplement Facts panel and no structure/function statement on the jar. |
The back panel says the jar is distributed by Frontier Co-op of Norway, Iowa. The Amazon listing's "Important information" box also carries the generic FDA disclaimer text that Amazon attaches to many food listings; the jar photos do not show any health statement that would call for it.
The plant behind it
Cinnamon is dried bark from trees in the genus Cinnamomum. NCCIH's cinnamon page lists two main species: Ceylon cinnamon (Cinnamomum verum, also known by the older name Cinnamomum zeylanicum), which grows primarily in Sri Lanka, and cassia cinnamon (Cinnamomum aromaticum, also called Cinnamomum cassia), which is grown in southeastern Asia and is the type most commonly sold in North America [1].
Frontier Co-op's own write-up on Ceylon cinnamon describes the harvest: the soft inner bark is exposed by hand, rolled into thin quills and dried [2]. The ground spice in this jar is that inner bark, milled to a powder. Frontier also writes that it sources its Ceylon cinnamon directly from co-ops in Sri Lanka, and that it offers Ceylon cinnamon with Regenerative Organic Certified and Fairtrade certifications [2]; both seals, plus USDA Organic, are printed on this jar.
In the kitchen the difference is mostly flavor and texture. Frontier describes Ceylon as delicate but complex, with floral and citrusy notes, and suited to dishes where cinnamon should enhance rather than overpower other flavors [2]; cassia is the bolder bark. That is why some bakers keep both: Ceylon for custards, poached fruit and drinks, cassia where a strong cinnamon note is wanted.
What the research says
Most published work on cinnamon is hard to apply to a kitchen jar. NCCIH notes that many cinnamon studies do not make clear which species or which part of the plant was tested, and that research does not clearly support using cinnamon for any health condition [1]. We do not suggest any health effect for this product.
The clearer science concerns chemistry. Coumarin is a natural flavor compound found in relatively high amounts in cassia-type cinnamons. A 2013 analysis by Wang and colleagues at the University of Mississippi compared authenticated bark samples and found that C. verum bark contained only traces of coumarin, while the three cassia species tested contained substantial amounts [3]. A 2012 Czech market survey likewise found high coumarin levels across 60 ground cinnamon samples from retail shelves, but none in a single C. verum sample imported from a Sri Lankan plantation [4]. Germany's Federal Institute for Risk Assessment (BfR) summarizes the same picture: Ceylon cinnamon contains low levels of coumarin, and cassia contains more [5]. These are measurements of bark, not of this particular jar, and we did not test it. Our note on Ceylon and cassia cinnamon covers the coumarin question in more detail.
According to NCCIH, cinnamon is likely safe in the amounts commonly used in food as a spice or flavoring; larger amounts or long-term use are sometimes associated with gastrointestinal problems or allergic reactions. NCCIH also says Ceylon cinnamon in larger amounts during pregnancy is considered unsafe, that little is known about larger amounts while breastfeeding, and that anyone taking medicine should talk with a health care provider before using cinnamon or other herbal products, because some herbs and medicines interact in harmful ways. NCCIH warns never to swallow dry cinnamon powder as a dare. Ask a clinician or pharmacist before using cinnamon in amounts beyond ordinary cooking.
Using it in an ordinary kitchen
This is a plain handling sequence for a jar of ground spice, not a promise of any result.
Check the jar on arrival
Make sure the cap and inner seal are intact and note any best-by date printed on the jar, since Amazon lists this item as non-returnable except when damaged or defective.
Store it away from heat and light
Keep the cap tight and the jar in a cupboard or drawer, not above the stove or on a sunny sill. Ground spice loses aroma faster than sticks.
Measure with a dry spoon
Steam and wet spoons make ground cinnamon clump. Shake or spoon out what the recipe calls for, away from a boiling pot.
Adjust for flavor, not habit
Ceylon tastes milder than supermarket cassia, so a recipe written for cassia may taste lighter. Add a little at a time and taste.
Replace when the smell fades
Rub a pinch between your fingers. If the sweet, warm aroma is faint, the flavor has faded too, and it is time for a fresh jar.
Price and where it is sold
On September 30, 2026 the Amazon listing showed $6.29 for the 1.76 oz jar, in stock, shipped and sold by Amazon.com (about $3.57 per ounce). The return line read "Non-returnable due to Food safety reasons," with a refund or replacement available if the item arrives damaged or defective. Prices change often, so check the Amazon listing for the current figure.
Who should look elsewhere
- Cooks who want the bold, familiar "cinnamon roll" flavor may prefer a cassia-type cinnamon, such as the McCormick jar in the same drawer.
- Anyone who wants to use cinnamon beyond ordinary cooking amounts, or who is pregnant, breastfeeding or taking medication, should first talk with a clinician or pharmacist, in line with NCCIH's general advice.
- Shoppers who want sticks (quills) rather than powder, or a larger bulk size, will need a different listing.
