Ceylon cinnamon comes from Cinnamomum verum, a tree native to Sri Lanka, while cassia comes from related Cinnamomum species grown in China, Vietnam, and Indonesia. They differ in bark thickness, color, and flavor. GlycoZen™ names its cinnamon as Ceylon Cinnamon and has not released an amount.

- Ceylon cinnamon is Cinnamomum verum, native to Sri Lanka.
- Cassia refers to several related species grown mostly in Asia.
- Look for the word Ceylon or the Latin name verum on a label.
- GlycoZen names Ceylon Cinnamon; no amount is published.
Two spices, one shared word
Walk down a spice aisle and the jar labeled simply "cinnamon" is, in most American stores, actually cassia. That surprises many cooks. Both come from the inner bark of evergreen trees in the genus Cinnamomum, so the shared name is not wrong, but they are different species with different habits.
The word Ceylon comes from the old name for Sri Lanka, the island where the true-cinnamon tree is native. Sri Lanka remains the best-known source.
Trade names add to the confusion. You may see Saigon cinnamon, Korintje cinnamon, or Chinese cinnamon, and all of those are cassia varieties named for their origins. The true-cinnamon tree, by contrast, tends to go by Ceylon, Sri Lankan, or Cinnamomum verum.
Telling them apart by eye
Shopping in person gives you the best clues. Whole sticks of each look quite different, and the contrast is easy to spot once you have seen both.
If you ever visit a spice shop, ask to see both side by side. Seeing the delicate quill next to a thick curl of cassia teaches more in ten seconds than a paragraph can.
- Ceylon: thin, papery layers rolled into a tight cigar shape, pale tan, brittle enough to crumble in your fingers.
- Cassia: thick bark curled from one side, reddish-brown, hard and difficult to snap.
- Ground Ceylon: lighter, tan color.
- Ground cassia: darker, reddish-brown color.

Cinnamomum verum, also written as Cinnamomum zeylanicum, is native to Sri Lanka and is also grown in parts of southern India and Madagascar. Growers harvest the inner bark from young shoots, then dry it so the thin sheets curl into quills.
Cassia is a family of species. Cinnamomum cassia is associated with southern China, Cinnamomum burmannii with Indonesia, and Cinnamomum loureiroi with Vietnam. Each carries its own character, which is why you may see regional names like Saigon or Korintje on a package.
Harvesting is labor intensive for true cinnamon. Workers peel thin inner bark, tuck the strips inside one another, and let them dry into long quills, then cut them to length. That hand work is part of why Ceylon often costs more per jar.
Flavor in the kitchen
Cooks often describe Ceylon as delicate, sweet, and slightly citrusy, a good match for custards, fruit, and light baking. Cassia is bolder and spicier, with the assertive bite many people associate with cinnamon rolls and holiday candy.
Neither is better as a flavor. They are simply different tools, and knowing which you hold helps you cook the way you intend.
A simple home experiment makes the difference clear. Grind each in a mortar, smell them side by side, and then taste a pinch stirred into warm oatmeal. Most people find that Ceylon smells gentler and more floral, while cassia hits with a spicier punch.
Reading the label with confidence
The most reliable label clues are the word Ceylon, the Latin name verum, or a stated country of origin. A bare "cinnamon" line leaves the species open.
GlycoZen names Ceylon Cinnamon as one of its four ingredients, and the brand has not released an amount, so this site does not quote one. To compare that wording with the other three ingredients, see the GlycoZen formula page.
For general guidance on spices and foods, the USDA's FoodData Central lists nutrient data for many ingredients. And when you are ready to learn about the product as a whole, start with what GlycoZen is or the full blog.
If you like cooking with cinnamon, keep both types in the pantry and label the jars yourself. A strip of masking tape with the species name saves guesswork months later.
A quick shopping checklist
Standing in front of a shelf of jars, the following checks take less than a minute and tell you what you are really holding.
- Look for Ceylon, verum, or Sri Lanka on the label.
- Check whether the product is sticks or ground; sticks reveal the layered quill.
- Compare color: pale tan versus reddish-brown.
- Read the ingredient line for any species name.
- Consider a bare cinnamon label an open question.
