A new study published in Food Chemistry, Molecular Sciences has found that excessive consumption of cinnamon may reduce the effectiveness of prescription medications. Researchers from the University of Mississippi Centre identified that cinnamaldehyde the key component in cinnamon can interfere with drug metabolism in the body.

Key Highlights

Study Findings

• The study found that consuming large amounts of cinnamon could lead to faster clearance of medications from the body.

• This can reduce the intended effectiveness of prescription drugs.

Supplement Overuse Warning

• Health concerns arise when cinnamon is consumed in high amounts, especially through supplements, without medical supervision.

• The study emphasized moderation when using cinnamon in the diet.

Statements from Leaders or Officials
“Health concerns could arise if excessive amounts of supplements are consumed without the knowledge of health care provider or prescriber of the medications. Overconsumption of supplements could lead to a rapid clearance of the prescription medicine from the body, and that could result in making the medicine less effective,”

Our best advice is to talk to a healthcare provider before using any supplements along with prescription medicine,”
