Anti-aging pill put to the test in healthy seniors
NCT ID NCT07195318
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a low-dose fisetin supplement (100 mg daily for 7 weeks) is safe and can reduce signs of inflammation and aging in healthy adults aged 50 and older. Researchers will measure changes in blood markers and track side effects. The goal is to see if this supplement, often advertised for anti-aging, actually works in people.
