Understanding the Two Main Cinnamon Varieties
When you reach for cinnamon powder, you are most likely holding one of two types: Ceylon or Cassia. The overwhelming majority of cinnamon found in grocery stores is the cheaper, more widely available Cassia variety. True Ceylon cinnamon, which is native to Sri Lanka and southern parts of India, is often labeled as such and comes with a higher price tag. For those concerned with health, this distinction is critical, as it hinges on a naturally occurring compound called coumarin.
The Critical Difference: Coumarin Content
Coumarin is a natural flavoring that can be toxic to the liver and kidneys in high doses. While all cinnamon contains some coumarin, the levels vary dramatically between the two types. Cassia cinnamon is a very rich source of coumarin, containing up to 1% of the compound by weight. In contrast, Ceylon cinnamon contains only trace amounts, often undetectable or at levels 250 times lower than Cassia.
For a regular cinnamon user, the difference is significant. According to the European Food Safety Authority (EFSA), the tolerable daily intake (TDI) of coumarin is 0.1 mg per kg of body weight. A healthy 150-pound (68 kg) adult can easily exceed this limit with just 1-2 teaspoons of Cassia cinnamon daily. With Ceylon cinnamon, a person can consume much larger amounts without reaching a toxic level, making it the clear choice for regular or therapeutic use.
Beyond Coumarin: Antioxidants and Health Benefits
Both Ceylon and Cassia cinnamon offer numerous health benefits, largely attributed to the compound cinnamaldehyde. This compound gives cinnamon its flavor and aroma and is responsible for many of its properties, including its antioxidant, anti-inflammatory, and antimicrobial effects. Both varieties may also help with blood sugar regulation and heart health. However, because Cassia poses a risk with consistent, high consumption, Ceylon is the safer option for maximizing health benefits long-term.
Quality and Purity: Avoiding Contaminants
Beyond the coumarin issue, recent reports from organizations like Consumer Reports have highlighted another purity concern: lead contamination in some cinnamon products. This heavy metal can pose serious health risks, particularly to children. The good news is that testing shows some brands contain virtually no lead, proving it is possible to produce a safe product. Always opt for brands that explicitly state their type (Ceylon vs. Cassia) and prioritize those independently tested for purity.
Comparison of Ceylon and Cassia Cinnamon
| Feature | Ceylon Cinnamon (Cinnamomum verum) | Cassia Cinnamon (Cinnamomum cassia) |
|---|---|---|
| Origin | Sri Lanka (formerly Ceylon), Southern India | China, Indonesia, Vietnam |
| Coumarin | Very low levels (0.004%) | High levels (up to 1%) |
| Flavor | Delicate, sweet, and mild with floral notes | Strong, spicy, and pungent |
| Appearance | Tan-brown, multiple thin, soft layers | Dark reddish-brown, single thick, hard layer |
| Best For | Daily use, light baking, desserts, beverages | Occasional use in savory dishes, intense flavor |
| Price | Higher due to labor-intensive harvest | Lower due to mass production |
Buying the Healthiest Cinnamon: Key Takeaways
Here are some final tips to ensure you are buying the healthiest cinnamon powder:
- Read the Label: Look for "Ceylon" or "Cinnamomum verum" on the ingredient list. If it simply says "cinnamon" or mentions China, Indonesia, or Vietnam, it is likely Cassia.
- Verify Brand Purity: Consider brands recommended by reputable third-party testing labs. Brands like 365 Whole Foods Market and Sadaf have shown low lead levels.
- Choose Organic: Organic certification can help ensure the product is free from pesticides and other additives, though it does not guarantee low coumarin or heavy metals.
- Store Properly: Ground cinnamon loses potency over time. Keep it in an airtight container away from heat and light to maximize its benefits. Grinding your own Ceylon sticks provides the freshest flavor.
- Understand Your Use: If you only use a small sprinkle on toast once in a while, Cassia is likely fine. If you consume cinnamon daily in smoothies, oatmeal, or supplements, switching to Ceylon is a simple but important health upgrade.

Conclusion: Making the Right Choice for Your Health
Deciding what is the healthiest cinnamon powder to buy comes down to understanding the critical differences between Ceylon and Cassia and being mindful of product purity. Ceylon cinnamon is the safest and healthiest choice for regular consumption due to its negligible coumarin content. While both varieties offer beneficial compounds, the potential for liver damage from high coumarin intake in Cassia makes it a less ideal long-term option, particularly for those using it for health purposes. Furthermore, due diligence in selecting a brand with a low-risk profile for lead and other contaminants is crucial for ensuring a pure and beneficial spice.
