Flavonoid fisetin aims to reverse vascular aging in seniors
NCT ID NCT06133634
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether intermittent doses of fisetin, a compound found in fruits and vegetables, can improve blood vessel function and reduce stiffness in arteries of adults aged 65 and older. Researchers will measure changes in blood flow and artery stiffness after one month, and check for safety. The goal is to see if fisetin can help manage age-related blood vessel problems.

Inclusion Criteria: * Age 65 years or older * Women must be postmenopausal * Body mass index (BMI) \<40 kg/m2 * Willing to accept random assignment * Weight stable in the prior 2 months (\<2 kg weight change) and willing to remain weight stable throughout the study * Ability to understand study procedures and to comply with them for the entire length of the study * No blood donation within 8 weeks prior to baseline testing; willingness to abstain from blood donation during the study and for 8 weeks after study completion * Absence of established, serious, unstable, chronic clinical disease (e.g., unstable CVD) as determined by study physician of record based on subject medical history, physical examination, resting ECG and standard clinical blood chemistries Exclusion Criteria: * Inability to refrain from alcohol for 24 hours prior to outcome assessment * Individuals taking fisetin, quercetin, luteolin, Dasatinib, piperlongumine or Navitoclax (supplements or drugs with established senolytic effects) within 6 months prior to baseline testing; should new research reveal other dietary supplements or drugs with potential senolytic effects, their use will be evaluated, and their use may lead to exclusion of the subject by the PI * New use of regular cardiovascular-acting medication which, in the opinion of the PI, affects the outcomes of the study within 3 months prior to starting baseline testing as reported during medication review during screening (these individuals could be enrolled after 3 months of regular use) * Chronic use of a dietary supplement which, in the opinion of the PI, affects the outcomes of the study, within 1 month prior to starting baseline testing as reported during medication review during screening (these individuals could be enrolled after 1 month of regular use) * Active malignancy (including myeloma) or malignancy that was active within 5 years prior to baseline testing * Inability or unwillingness of individual to give written informed consent * Current or past participation within 3 months in another clinical trial that, in the opinion of the PI, would affect the outcomes of the study * Known hypersensitivity or allergy to fisetin * Blood donation within 2 months prior to baseline testing * Resting blood pressure \>160 mmHg systolic or \>110 mmHg diastolic * Regular vigorous aerobic/endurance exercise
