Studies in animals suggest the naturally occurring flavonoid may reduce inflammation and target aging cells, though human evidence remains limited.

Emerging research has identified fisetin, a naturally occurring compound found in strawberries and other foods, as a potential factor in improving vascular health by targeting cellular aging processes.
A study published in Aging Cell examined the effects of fisetin on age-related changes in blood vessels, focusing on senescent cells—damaged cells that accumulate over time and contribute to inflammation and tissue dysfunction. In laboratory findings, fisetin was associated with a reduction in these cells and improvements in vascular function.
Researchers observed that older laboratory mice treated intermittently with fisetin showed decreased levels of senescent cells in blood vessels, along with reduced inflammatory signaling. One marker linked to inflammation, CXCL12, declined following treatment. The study also reported improvements in the ability of blood vessels to expand and contract, a function that typically declines with age.
Additional testing involved exposing healthy vascular cells to plasma from older animals, which led to signs of accelerated cellular aging. When fisetin was introduced, researchers noted that some of these effects were reduced, suggesting both protective and restorative properties in controlled conditions.
Separate studies have explored fisetin’s potential neurological effects. Research in animal models has indicated that the compound may influence oxidative stress and inflammation in the brain. Some findings have linked fisetin to increased levels of glutathione, a naturally occurring antioxidant, and reduced formation of amyloid-related markers associated with neurodegenerative conditions. Animal-based experiments have also suggested possible effects on neuron growth and connectivity.
While these findings point to possible health benefits, researchers emphasize that most current evidence comes from preclinical or animal studies. The extent to which these results translate to human health outcomes remains under investigation.
Fisetin occurs naturally in several foods, with strawberries identified as one of the richest sources. Other foods containing the compound include apples, onions, cucumbers, and persimmons. These foods also provide additional nutrients such as fiber and vitamins.
Health experts note that diet and lifestyle remain central to long-term cardiovascular and metabolic health. Diets rich in fruits and vegetables have been consistently associated with improved health outcomes, though isolating the effects of individual compounds requires further study.
Researchers involved in fisetin studies have indicated that additional clinical trials in humans are needed to better understand dosage, safety, and long-term effects before any therapeutic recommendations can be established.
