FAQ

Frequently Asked Questions About Fisetin

What natural foods are highest in fisetin?

Strawberries contain the highest levels of fisetin among common foods, followed by apples, persimmons, onions, and cucumbers. Eating a variety of these fruits and vegetables can provide natural dietary sources of fisetin, although supplement forms are typically used for higher, more consistent intake.

How does fisetin work to support healthy aging?

Fisetin is studied for its ability to act as an antioxidant and modulate cellular processes involved in oxidative stress and senescence. Research suggests fisetin may help the body clear out senescent cells, which accumulate with age and contribute to cellular aging, supporting healthier cellular function over time.

What is the difference between fisetin and quercetin?

Both fisetin and quercetin are flavonoid antioxidants found in plants, but fisetin is particularly noted for its potential effects on cellular senescence and cognition. While they share some similar properties, fisetin is more abundant in strawberries and is researched more for its role in healthy aging, whereas quercetin is common in onions and apples.

Are there any safety concerns or interactions with fisetin supplements?

Fisetin is generally considered well tolerated, but high doses may interact with certain medications, especially those affecting blood clotting or liver metabolism. Individuals on medication or with existing health conditions should consult a healthcare provider before using fisetin supplements, as its effects in combination with drugs are not fully understood.
