Coumarin is a chemical compound commonly found in cinnamon and Other plants. It is known for its sweet aroma and potential health effects, both beneficial and harmful, depending on the variety and amount consumed. This article delves into the types of cinnamon, their coumarin levels, health implications, and safe usage recommendations.
Understanding Cinnamon Varieties and Coumarin Content
Cinnamon is one of the most popular spices worldwide, but not all cinnamon is created equal. The two primary types of cinnamon are Ceylon cinnamon (Cinnamomum verum) and Cassia cinnamon (Cinnamomum cassia). The key difference between them lies in their coumarin content.
| Type of Cinnamon | Scientific Name | Coumarin Content |
|---|---|---|
| Ceylon Cinnamon | Cinnamomum verum | ~0.004% (trace amounts) |
| Cassia Cinnamon | Cinnamomum cassia | Up to 1% (significant) |
Ceylon cinnamon is often referred to as “true cinnamon” and is preferred for its lower coumarin content and sweeter flavor. Cassia cinnamon, on the other hand, is the prevalent form found in supermarkets and typically contains much higher levels of coumarin.
What Is Coumarin?
Coumarin is a naturally occurring compound with potential medicinal properties, including anti-inflammatory and anticoagulant effects. However, it can also pose health risks, particularly in large quantities. Studies indicate that high levels of coumarin can lead to liver damage and may have carcinogenic effects in certain populations.
According to research, Cassia cinnamon may contain about 5 to 25.7 mg of coumarin per teaspoon, while Ceylon cinnamon usually has less than 0.5 mg. This stark contrast is crucial for consumers, particularly those who use cinnamon regularly in cooking or as a dietary supplement.
Health Implications of Consuming Coumarin
-
Liver Damage: The most pressing concern associated with coumarin consumption is its link to liver toxicity. Prolonged or excessive intake of cassia cinnamon can lead to liver damage, especially in individuals with pre-existing liver conditions or those who consume other substances that affect liver health.
-
Carcinogenic Potential: Studies have suggested that high-dose coumarin could potentially lead to cancer in certain animals, raising concerns about its long-term effects on humans.
-
Allergic Reactions: Some individuals may experience allergic reactions to coumarin, manifesting in symptoms such as skin irritation or respiratory issues.
-
Blood Thinning Properties: While coumarin has beneficial effects in terms of blood thinning and circulation, excessive consumption can increase the risk of bleeding, particularly in individuals on anticoagulant medications.
Recommended Daily Intake
The European Food Safety Authority has recommended that adults limit their coumarin intake to a maximum of 0.1 mg per kg of body weight. For an average adult weighing 70 kg (154 lbs), this translates to approximately 7 mg of coumarin per day.

Opt for Ceylon Cinnamon
To reduce the risk associated with coumarin, consumers should opt for Ceylon cinnamon whenever possible. Ceylon cinnamon can often be found in specialty stores and is increasingly available in supermarkets. It may come at a higher price but offers peace of mind for health-conscious individuals.
Read Labels
If you purchase cinnamon products, check for labeling that specifies the type of cinnamon and its coumarin content. Understandably, this may not always be clear, and it’s safer to choose products from reputable sources that provide transparency regarding their ingredients.
Limit Consumption Quantity
Be mindful of how much cinnamon you add to your diet. Even with Ceylon cinnamon, moderation is key. If using powdered cinnamon, try to limit your average daily intake to a teaspoon or less.
