Researchers are examining a naturally occurring flavonoid found in common fruits as part of a broader effort to address the underlying biological processes of aging.

A naturally occurring compound found in fruits such as strawberries and apples is gaining attention in scientific research for its potential role in targeting cellular aging, with early studies suggesting it may influence inflammation and physical decline associated with aging.

The compound, known as fisetin, is a flavonoid present in a range of plant-based foods. Researchers are increasingly studying its classification as a “senolytic,” a type of compound that targets and helps remove senescent cells—aged cells that no longer divide but remain metabolically active. These cells accumulate over time and are associated with chronic inflammation and tissue dysfunction.

Scientists have identified senescent cells as a contributing factor in age-related conditions, including cardiovascular disease, reduced muscle function and cognitive decline. These cells release inflammatory signals that can disrupt surrounding healthy tissue, making their accumulation a focus of ongoing aging research.

Recent experimental findings have positioned fisetin as a candidate for influencing this process. A 2025 study published in Aging Cell reported that intermittent fisetin administration in aged mice was associated with improved physical function and reduced markers of frailty. Researchers noted that these outcomes were comparable to results observed with certain pharmaceutical interventions and genetic approaches designed to address cellular aging.

The proposed mechanism involves fisetin’s interaction with biological pathways that regulate inflammation and cellular survival. By supporting the removal of senescent cells, the compound may contribute to reduced systemic inflammation, a factor commonly linked to chronic disease progression.

Early human studies have produced preliminary findings consistent with these observations. Research involving individuals recovering from stroke or managing conditions such as colorectal cancer has shown associations between fisetin supplementation and reductions in inflammatory markers, along with improvements in certain functional outcomes. Larger clinical trials are ongoing to further evaluate its effects on vascular health, physical performance and age-related frailty.

Fisetin is found in a variety of foods, with higher concentrations reported in strawberries and the skin of apples. It is also present in smaller amounts in foods such as cucumbers, onions, grapes and kiwis. Nutrition researchers note that incorporating these foods into a balanced diet provides a practical way to increase intake of naturally occurring flavonoids.

Dietary strategies emphasizing a range of plant-based foods are frequently cited in research examining long-term health outcomes. Scientists have observed that compounds like fisetin may act alongside other plant-derived substances, including quercetin and anthocyanins, which are found in vegetables and berries and have been studied for their roles in inflammation and cellular function.

The growing focus on fisetin reflects a broader shift in aging research toward addressing root biological mechanisms rather than only treating later-stage disease. Investigators are increasingly examining how cellular processes contribute to overall health outcomes and how nutritional compounds may interact with those processes.

Researchers continue to emphasize that findings remain under study, particularly in human populations, and that dietary compounds are being evaluated as part of a wider framework that includes lifestyle and environmental factors.
