Free · No account · based on published sources including NIH ODS, FDA drug labels, and peer-reviewed literature
Therapeutic doses of cinnamon (1–6g/day) should be disclosed to your prescriber. Avoid high-dose cinnamon supplements. Cassia cinnamon in large amounts also carries coumarin-related liver toxicity risk. Monitor glucose if using regularly.
Why this interaction occurs
Cinnamon has demonstrated modest insulin-sensitizing effects and postprandial glucose reduction in clinical trials, likely via insulin receptor signaling enhancement. When layered onto semaglutide-mediated GLP-1 activity, cumulative glucose lowering is plausible. Evidence is inconsistent but warrants caution at supplemental doses.
Evidence
Evidence level: limited.
