Ceylon vs Cassia Cinnamon: Health Risks, Best Uses & Buying Guide

Ceylon vs Cassia: Key Differences Explained

Ceylon and Cassia are the two primary cinnamon types, but they differ significantly in health implications, flavor profiles, and culinary applications. Cassia cinnamon contains high levels of coumarin—a compound that can cause liver damage with regular consumption—while Ceylon cinnamon has negligible coumarin levels, making it the safer choice for daily use. Here's what you need to know to select the right cinnamon for your kitchen.

Understanding Cinnamon Types: Ceylon, Cassia & Subtypes

While "cinnamon" is often used generically, there are distinct varieties with unique characteristics:

  • Ceylon Cinnamon (True Cinnamon): Sourced from Sri Lanka, it features delicate, sweet flavor with citrus notes and thin, layered bark. Contains less than 0.01% coumarin, making it safe for daily consumption.
  • Cassia Cinnamon: The dominant commercial variety (90% of global supply), originating from China and Indonesia. Includes two main subtypes:
    • Saigon Cinnamon (Vietnamese Cassia): Highest in essential oils and coumarin (up to 1%), delivering intense flavor for spiced beverages.
    • Korintje Cinnamon (Indonesian Cassia): Moderate coumarin levels with bold, woody flavor commonly found in supermarkets.

Critical Comparison: Ceylon vs Cassia Cinnamon

Feature Ceylon Cinnamon Cassia Cinnamon
Origin Sri Lanka China, Vietnam, Indonesia
Coumarin Content 0.004-0.05% (safe for daily use) 0.4-1.0% (high risk with regular consumption)
Flavor Profile Mild, sweet, complex with citrus notes Strong, spicy, woody with sharp bite
Bark Texture Thin, paper-like layers that crumble easily Thick, rigid bark that requires grinders
Price Range $8-$15 per ounce (premium) $2-$5 per ounce (affordable)
Health Considerations Safe for daily consumption at any quantity Limit to 1 tsp/day due to coumarin toxicity

Optimal Uses by Cinnamon Variety

  • Ceylon Cinnamon: Ideal for delicate desserts (custards, crème br»le), morning oatmeal, herbal teas, and dishes where subtle spice is preferred. Its low coumarin makes it perfect for children and daily consumption.
  • Saigon Cinnamon: Best for intense applications like mulled wine, chai lattes, and spiced baked goods where maximum flavor impact is needed. Use sparingly due to high coumarin levels.
  • Korintje Cinnamon: Versatile for everyday baking (cookies, breads), coffee blends, and savory dishes like curries. Offers strong flavor at affordable prices but should be limited to occasional use.

Pro Tip: Fresh Grinding Matters

Ground cinnamon loses potency 3x faster than whole sticks. For maximum flavor, grind whole cinnamon quills just before use using a dedicated spice grinder.

Frequently Asked Questions

What's the main health risk with Cassia cinnamon?

Cassia contains high levels of coumarin (up to 1%), which can cause liver damage with regular consumption. Health authorities recommend limiting Cassia to 1 teaspoon per day for adults. Ceylon cinnamon contains 100-200x less coumarin and is safe for daily use.

Can I substitute Cassia for Ceylon in recipes?

Yes, but adjust quantities: Cassia is 2-3x stronger than Ceylon. For delicate desserts, use 1/2 to 1/3 the amount of Cassia. For robust recipes like gingerbread, Cassia works well but limit consumption frequency due to coumarin risks.

Why is Ceylon cinnamon more expensive?

Ceylon requires meticulous hand-harvesting of thin bark from specific trees in Sri Lanka, with lower yields per tree. Cassia comes from faster-growing trees in China/Vietnam with industrial-scale harvesting, making it 3-5x cheaper to produce.

How much cinnamon is safe to consume daily?

For Ceylon: No established limit—safe for regular consumption. For Cassia: Maximum 1 teaspoon (2g) per day for adults. Children should avoid Cassia entirely. Consult your doctor if you have liver conditions.

Does cinnamon expire?

Cinnamon doesn't spoil but loses potency. Ground cinnamon stays fresh 6-12 months; whole sticks last 2-3 years. The best freshness test is aroma—if it smells faint or musty, replace it regardless of expiration date.

Is "cinnamon" on supermarket labels always Cassia?

Yes. Over 90% of cinnamon sold in U.S. supermarkets is Cassia (often labeled simply "cinnamon"). True Ceylon is typically labeled "Ceylon cinnamon" or "True cinnamon" and sold in specialty stores or online.
