100 peer-reviewed studies

What the evidence says

Mostly mechanism / observational

Most Cinnamon studies are mechanism or observational rather than RCTs that measure a clinical effect — keep findings provisional.

Most evidence is from high-quality meta-analyses and randomised trials published 2003–2026 with a typical study size of 77 participants.
