Oxford, Mississippi — New research from the University of Mississippi has revealed that consuming high amounts of cinnamon may interfere with the effectiveness of some prescription medications. The primary compound in cinnamon, known as cinnamaldehyde, activates specific body receptors that can accelerate the breakdown of certain drugs, potentially diminishing their efficacy.
While small amounts of cinnamon sprinkled into foods or drinks pose minimal risk, experts warn that excessive consumption—especially through supplements—can lead to significant health complications. Shabana Khan, a principal scientist involved in the study, cautioned those using prescription medications against taking cinnamon supplements without consulting their healthcare providers. “Excessive supplement use can lead to quicker clearance of medications from the body,” she said, highlighting the critical need for cautious consumption.
Researchers identified that Cassia cinnamon, the more affordable variety commonly found in grocery stores, carries a higher risk of negative interactions compared to true cinnamon sourced from Sri Lanka. The latter boasts lower levels of coumarin, a substance that can affect blood thinning in individuals with certain medical conditions. Amar Chittiboyina, co-author of the study, noted that while cinnamon in everyday culinary use typically poses less danger, the bark from Cassia cinnamon could lead to complications for those on anticoagulant medications.
Consumers often remain unaware of the potential dangers linked to large amounts of cinnamon. Khan emphasized the importance of consulting with healthcare providers, especially for individuals with chronic illnesses such as hypertension, diabetes, or cancer. “Our best advice is to engage with a health care professional before introducing any new supplements,” she advised, stressing that supplements are not intended to treat or cure medical conditions.
Health experts recommend that anyone regularly consuming cinnamon or considering its use as a supplement should discuss their options with medical professionals. This is particularly important for individuals taking medications essential for managing ongoing health issues to avoid any unintended side effects.
By fostering awareness around the relationship between cinnamon and prescription medications, the researchers hope to prevent adverse health effects and promote safer usage of this popular spice. As consumers continue to seek natural remedies and supplements, proper education and guidance from healthcare providers remain vital in ensuring health and safety.
