Outcomes where both Cinnamon and Efpeglenatide have evidence — compare verdict strength side-by-side.
1,000 mg (1 g) cinnamon powder daily, or 250-500 mg standardized extract. Prefer Ceylon for regular use. The cited type 2 diabetes trial used 500 mg bark powder capsules, two a day. Label products go up to 6 g of powder a day, a figure from the ranges of the cited meta-analyses but not the dose of any cited trial. A cited dose-response meta-analysis found fat mass fell only at 2 g a day or more taken for at least 12 weeks.
With meals
Ceylon cinnamon powder or standardized aqueous extract
INVESTIGATIONAL — NO approved or consumer dose. In trials, efpeglenatide was given as a once-weekly subcutaneous injection, titrated up to 4-6 mg (AMPLITUDE-O used 4 and 6 mg) with gradual escalation to limit GI side effects. Not for self-administration; it is an unapproved, unmarketed investigational drug.
