The Core Difference: Cassia vs. Ceylon
Not all cinnamon is created equal. The spice aisle typically stocks Cassia, the more common and affordable variety, but serious health and culinary distinctions separate it from the less common Ceylon, or “true” cinnamon. Both are derived from the inner bark of Cinnamomum trees, but the species and processing lead to significant differences in appearance, flavor, and most importantly, chemical composition.
Cassia cinnamon comes primarily from China, Indonesia, and Vietnam, where it is often labeled as simply “cinnamon”. Its bark is thick, tough, and forms a hollow tube when dried. It is known for its strong, pungent, and spicy flavor. In contrast, Ceylon cinnamon is native to Sri Lanka and parts of southern India. The inner bark is thin, soft, and forms multiple papery layers when dried, creating a fine, delicate texture. Its flavor is milder, sweeter, and more complex, with subtle citrus and floral notes.
The Coumarin Factor and Liver Health
This is the most critical health consideration when choosing between the two types. Coumarin is a natural chemical compound found in various plants, and in high doses, it is known to be a hepatotoxin, meaning it can cause liver damage.
- Cassia's high coumarin content: The most common Cassia cinnamon contains significant levels of coumarin. Some varieties, like Saigon cinnamon, contain even higher amounts. For individuals who use cinnamon regularly, especially in larger quantities, the coumarin levels in Cassia can pose a health risk. The European Food Safety Authority has established a tolerable daily intake (TDI) for coumarin, and just 1–2 teaspoons of Cassia could exceed this limit for some people. People with pre-existing liver conditions should be especially cautious.
- Ceylon's minimal coumarin: Ceylon cinnamon, however, contains only trace amounts of coumarin—about 250 times less than Cassia, to the point where it is often undetectable. This makes Ceylon the overwhelmingly safer choice for those who want to consume cinnamon frequently or in larger doses, such as in supplements or daily beverages.
Health Benefits of Both Varieties
Despite the difference in coumarin, both types of cinnamon share many of the same general health benefits, thanks to compounds like cinnamaldehyde.
- Rich in antioxidants: Both Ceylon and Cassia contain high levels of powerful antioxidants that help combat oxidative stress caused by free radicals. This can help protect the body from a range of chronic diseases.
- Supports blood sugar management: Cinnamon is well-known for its potential to help regulate blood sugar levels by improving insulin sensitivity. Some studies on managing type 2 diabetes have used Cassia, showing promising results, while other research has focused on Ceylon.
- Anti-inflammatory and antimicrobial properties: Both varieties have demonstrated anti-inflammatory, antibacterial, and antiviral effects. Cinnamaldehyde, responsible for cinnamon's characteristic aroma, is a key component providing antimicrobial benefits.
Ceylon vs. Cassia Cinnamon: A Comparison
| Feature | Ceylon Cinnamon | Cassia Cinnamon |
|---|---|---|
| Origin | Sri Lanka, Southern India | China, Indonesia, Vietnam |
| Flavor | Mild, sweeter, delicate, with citrus/floral notes | Strong, pungent, spicy, and sometimes bitter |
| Appearance | Light brown, soft, thin, multi-layered quills | Dark reddish-brown, thick, coarse, single-layer quills |
| Coumarin Content | Very Low (often undetectable) | High |
| Price | More expensive | Inexpensive and widely available |
| Culinary Uses | Delicate desserts, beverages, custards | Bold baked goods, savory dishes, mulled drinks |
| Best for Daily Use | Recommended due to low coumarin | Consume in moderation due to high coumarin |
Making the Right Choice for Your Diet
Your choice between Ceylon and Cassia depends on your dietary habits and intended use.
- For regular, heavy consumption: If you frequently use cinnamon in smoothies, oatmeal, coffee, or take supplements, Ceylon is the clear choice. Its negligible coumarin levels make it safe for daily intake without posing a risk of liver damage.
- For occasional use: If you only use cinnamon occasionally for baking or in recipes, Cassia is generally safe in small amounts. However, since it is difficult to determine exactly how much coumarin is in a particular product, it is best to be cautious, especially for at-risk individuals.
- For specific culinary flavor: The flavor profiles are different. If a recipe calls for a delicate, subtle cinnamon flavor, Ceylon is the superior choice. If a bold, assertive, and spicy cinnamon taste is needed, Cassia might be preferable for that specific application.
When shopping for ground cinnamon, labels can be deceiving, as most standard store-brand cinnamon is the Cassia variety. To be sure you're getting Ceylon, you will need to specifically look for labels that say “Ceylon” or “True Cinnamon” and be prepared for a higher price point.

Conclusion
In summary, while both Cassia and Ceylon cinnamon offer valuable health benefits, Ceylon is the healthier choice for anyone who consumes cinnamon regularly due to its significantly lower coumarin content. Cassia cinnamon, while safe in small, occasional doses, poses a risk of liver damage if consumed in large quantities over time. By understanding these key differences, you can make an informed decision that aligns with your dietary needs and health goals, ensuring you get the most from this wonderful spice without the potential risks associated with high coumarin intake.
