Cinnamon Supplements May Pose Health Risks, Experts Say
Cinnamon, especially Cassia cinnamon, may contain high levels of coumarin, a natural compound that can thin the blood and potentially harm the liver. A new study found that cinnamaldehyde, the active ingredient in cinnamon, is easily absorbed in the body and may interfere with how drugs are metabolized. Overconsumption of cinnamon supplements could lead to harmful herb-drug interactions, particularly for those with chronic conditions like hypertension, diabetes, or liver disease.

Consult Before Taking Cinnamon Supplements
Experts warn that people on medications, especially blood thinners or drugs metabolized by the liver, should consult their doctors before taking cinnamon supplements. Common culinary use, like sprinkling cinnamon on coffee or food, is considered safe. However, taking concentrated forms like capsules over long periods may increase health risks without clear proven benefits.Cinnamon is a spice that comes from the bark of cinnamon trees.

FDA Does Not Fully Regulate Supplements
Consumers should note that the FDA does not regulate dietary supplements the same way as prescription drugs. Products are not reviewed before reaching the market, and safety issues are typically addressed only after incidents occur. Experts advise discussing any supplement use with a health care provider to avoid harmful interactions.
