Ceylon Cinnamon: The Best Type for High Blood Pressure?

4 min read

Research has consistently shown that cinnamon can help reduce blood pressure and improve overall heart health. However, the type of cinnamon you consume is a crucial factor due to a compound called coumarin, which can be harmful in large amounts.

Quick Summary

The Ceylon variety, known as "true cinnamon," is the safest choice for regular consumption due to its significantly lower coumarin content. While Cassia cinnamon is widely available, its high coumarin levels can pose health risks, particularly liver damage, with long-term, high-dose intake. Choosing the right type of cinnamon is essential for maximizing potential health benefits while minimizing risks.

Key Points

  • Ceylon vs. Cassia: The key difference lies in coumarin content; Cassia has high levels, while Ceylon has trace amounts.

  • Ceylon is Safest: Due to its minimal coumarin, Ceylon cinnamon is the best and safest type for long-term consumption, especially in higher amounts for potential health benefits.

  • Risks of Cassia: Regular, high intake of Cassia cinnamon can lead to liver damage because of its high coumarin levels.

  • Potential Blood Pressure Benefits: Cinnamon may help lower blood pressure by relaxing blood vessels and providing anti-inflammatory and antioxidant effects.

  • Not a Standalone Treatment: Cinnamon is a complementary supplement, not a replacement for prescribed medication or a healthy lifestyle.

  • Consult a Doctor: Always discuss adding cinnamon supplements with a healthcare provider, especially if you are on blood pressure or diabetes medication.

Ceylon vs. Cassia: Why the Type of Cinnamon Matters for Blood Pressure

When exploring cinnamon as a supplement for managing high blood pressure, understanding the difference between the main commercial types—Ceylon and Cassia—is vital. While both offer a host of health benefits, their compositional differences, particularly their coumarin content, have major implications for long-term safety, especially when consumed in medicinal amounts. This distinction is critical for anyone looking to use this spice therapeutically.

The Health Benefits of Cinnamon for High Blood Pressure

Before delving into the differences, it's important to recognize why cinnamon is even considered for hypertension management. Research suggests several mechanisms by which cinnamon can help lower blood pressure:

  • Vessel Relaxation: Animal studies indicate that cinnamon can help dilate and relax blood vessels, which improves blood flow and subsequently reduces pressure.
  • Antioxidant Properties: The spice is rich in antioxidants, which combat oxidative stress and inflammation, both of which are contributing factors to high blood pressure and cardiovascular disease.
  • Improved Lipid Profile: Some studies suggest that cinnamon can improve blood lipid profiles by reducing levels of LDL ("bad") cholesterol and triglycerides, further supporting heart health.
  • Insulin Sensitivity: Because diabetes and insulin resistance are often linked to hypertension, cinnamon's ability to help regulate blood sugar may also indirectly contribute to better blood pressure control.

The Critical Difference: Coumarin

The most significant factor differentiating Ceylon and Cassia cinnamon is their coumarin content. Coumarin is a naturally occurring plant compound that can be toxic to the liver in large amounts. This is where the choice between the two types becomes critical for regular use.

Cassia Cinnamon

  • High Coumarin Content: Cassia cinnamon, the most common and inexpensive variety found in grocery stores, can contain significant amounts of coumarin. The amount varies, but it can be high enough that even regular, moderate consumption might exceed safe daily limits, especially for individuals with liver issues.
  • Potential Liver Damage: Prolonged, high intake of coumarin from Cassia cinnamon is linked to liver damage in sensitive individuals. Health authorities, particularly in Europe, have issued warnings regarding high coumarin intake from foods.
  • Widely Available: Most cinnamon sticks and ground cinnamon sold in the US and Canada are Cassia, often simply labeled as "cinnamon".

Ceylon Cinnamon

  • Low Coumarin Content: Known as "true cinnamon," Ceylon cinnamon contains only trace amounts of coumarin, making it the safer option for regular and prolonged use.
  • Delicate Flavor: Ceylon has a milder, sweeter, and more delicate flavor profile compared to the spicier, more pungent Cassia.
  • Specialty Item: It is typically more expensive and found in health food stores or specialty spice shops.

How to Choose and Use Cinnamon for High Blood Pressure

For those intending to use cinnamon therapeutically for high blood pressure, Ceylon is the definitive choice due to its low coumarin content and high safety profile for long-term use. Here are some guidelines:

  1. Opt for Ceylon: Whenever possible, purchase Ceylon cinnamon, especially if you plan to consume it regularly in medicinal quantities beyond simple culinary use. Look for products specifically labeled "Ceylon" cinnamon.
  2. Use in Cooking: Incorporate Ceylon cinnamon into your daily diet by sprinkling it on oatmeal, yogurt, or fruit. A moderate amount used for flavor in cooking is generally safe regardless of type, but Ceylon removes all risk.
  3. Monitor Your Intake: If you can only find Cassia, be mindful of your intake. Small, sporadic amounts in cooking are usually not a concern, but avoid high amounts or supplements.
  4. Consider Supplements: For therapeutic use, Ceylon cinnamon supplements are available. Always consult a healthcare provider before starting any new supplement regimen, as cinnamon can interact with certain blood pressure and diabetes medications.

Final Recommendations and Considerations

While cinnamon can be a beneficial addition to a heart-healthy lifestyle, it is not a standalone treatment for high blood pressure. It works best as a complementary approach alongside conventional medical treatments, a healthy diet, and regular exercise. The choice of Ceylon cinnamon minimizes safety concerns related to coumarin toxicity, allowing for more consistent and regular intake to potentially support cardiovascular health.

Conclusion: Making the Right Choice

The best type of cinnamon for high blood pressure is unequivocally Ceylon due to its negligible coumarin content, which makes it safe for regular, long-term consumption. While both cinnamon types offer potential health benefits like blood vessel relaxation and antioxidant effects, the coumarin in Cassia poses a risk of liver damage when consumed in larger, medicinal amounts. By selecting Ceylon cinnamon and incorporating it into a comprehensive heart-healthy plan under medical supervision, individuals can benefit from its potential hypotensive effects while prioritizing safety.

Frequently Asked Questions

Ceylon cinnamon, often called "true cinnamon," is the safest for daily use due to its extremely low levels of coumarin, a compound that can be toxic to the liver in high doses.

Coumarin is a natural compound found in varying amounts in cinnamon. In high concentrations, particularly from Cassia cinnamon, it can be harmful to the liver and kidneys with regular consumption. Health authorities have established tolerable daily intake limits for coumarin.

Most grocery store cinnamon is Cassia, which contains high levels of coumarin. While small amounts for flavoring are generally fine, using it in large, medicinal amounts for high blood pressure is not recommended due to the risk of coumarin toxicity.

Ceylon cinnamon sticks are thin, soft, and have multiple fragile layers that crumble easily. Cassia sticks are typically thicker, harder, and consist of a single rolled layer. Ground cinnamon is almost impossible to differentiate by appearance alone.

Cinnamon is thought to help lower blood pressure by acting as a vasodilator, relaxing blood vessels and improving circulation. It also possesses antioxidant and anti-inflammatory properties that support overall cardiovascular health.

Studies have explored various amounts of Ceylon cinnamon for health benefits. Given its low coumarin content, concerns about toxicity are significantly lower compared to Cassia. However, it is always best to consult a doctor for personalized advice.

No, cinnamon is not a replacement for prescribed high blood pressure medication. It should be used as a complementary dietary supplement under the guidance of a healthcare professional as part of a comprehensive treatment plan.
