Fisetin benefits: where the science stands
Almost nobody has looked.
As of August 2026, 56 papers on PubMed mention fisetin, but almost none put it to a real test. For inflammation, the best evidence is just two trials, 81 people in all, with mixed results. Too thin to settle it. Every claim we checked is below.

Fair questions
Does fisetin work?+
Nobody can honestly say: almost no real studies exist, whatever the label promises.
Is fisetin safe?+
No caution is recorded on this page. That is not a safety guarantee; the studies we read were not safety trials.
How many studies exist?+
56 on PubMed for fisetin itself; the count is measured from PubMed, not estimated. We read the three strongest and linked every one above.
