Cinnamon Variety Matters in Medication Interaction Risk

Studies from the University of Mississippi show that cinnamaldehyde, the primary compound in cinnamon, can speed up the body's metabolism of certain prescription medications, potentially reducing their effectiveness. The risk is higher with excessive cinnamon intake, particularly from supplements and the Cassia variety, which contains more coumarin and is especially dangerous for people taking blood thinners. In contrast, true Ceylon cinnamon is considered safer due to its lower coumarin content, and cinnamon oil poses minimal risk of drug interactions. While cinnamon has recognized benefits for blood sugar, cholesterol, and blood pressure, experts advise moderation and consulting a healthcare provider before using supplements. Not all forms of cinnamon pose the same risk for medication interaction. These findings urge caution for those using prescription drugs alongside cinnamon supplements.
