Cinnamon is widely regarded as a healthy spice, but in supplement form, it may interfere with certain medications. A new study found that high doses of cinnamon may cause the body to metabolize some medications more quickly, reducing their effectiveness. This is especially a concern for people taking medication for diabetes, high blood pressure, or depression.
The study highlights a compound in cinnamon called cinnamaldehyde. It may trigger the body to remove medicine too quickly. Cassia cinnamon, a common variety, also contains coumarin — a compound that can thin the blood and potentially damage the liver when consumed in high amounts. This makes supplements a risky choice for some people, especially those on blood thinners.
Experts say it's safe to enjoy small amounts of cinnamon in your food. You can sprinkle it on oatmeal, coffee, or baked goods without worry. But before taking cinnamon supplements, talk to your doctor or a dietitian. Using it in meals as part of a healthy diet is the safest option.
