Chlorogenic acids are compounds found in coffee and are frequently invoked in green-coffee and metabolism marketing.
Weight-management evidence
NIH's professional review describes green coffee bean extract research as limited, with few clinical trials and poor methodological quality, while noting a possible modest effect on body weight. That is a signal for further study, not a guarantee.
For buyers
Check whether the label identifies the source, amount and standardization. A named compound on a sales page does not reveal whether a product matches doses used in research.
