Unpacking the bioavailability of Fisetin

When it comes to Fisetin, a flavonoid found in various fruits and vegetables such as strawberries, apples, cucumbers, and onions, understanding its bioavailability is crucial for grasping its therapeutic potential.

Fisetin’s bioavailability from dietary sources is considered low, which means that the body absorbs a relatively small amount of Fisetin when consumed through food.

Why is Fisetin’s bioavailability low?

The low bioavailability of Fisetin can be attributed to several factors, including its limited solubility in water and challenges in crossing the intestinal barrier for efficient absorption.

Additionally, Fisetin undergoes rapid metabolism in the body, further reducing the amount available for use in various physiological processes.

The case for supplementation

Given the challenges associated with obtaining sufficient Fisetin from dietary sources alone, supplementation becomes a viable consideration for unlocking its potential therapeutic effects.

By taking Fisetin supplements, individuals can ensure a more consistent and potentially higher intake of this beneficial compound, increasing the likelihood of experiencing its reputed health benefits.

While consuming Fisetin-rich foods is still valuable for overall health, supplementation offers a targeted approach for harnessing the therapeutic properties of this elusive flavonoid.

Misconceptions about Fisetin Bioavailability

Exceptionally high

Contrary to what some may think, the bioavailability of Fisetin from dietary sources is not exceptionally high. In fact, studies have shown that the body only absorbs a small percentage of Fisetin when consumed through food sources.

Fisetin is a flavonoid that has poor water solubility, which hinders its absorption in the body. This low bioavailability means that relying solely on dietary sources may not provide sufficient levels of Fisetin for therapeutic effects.

Unnecessary as the body produces sufficient amounts

While it’s true that the body can produce some Fisetin, it is not produced in amounts significant enough to meet therapeutic needs. Depending on endogenous production alone may not provide the levels required for potential health benefits.

Supplementation or seeking out more concentrated sources of Fisetin may be necessary to achieve the desired effects, particularly for those looking to harness its antioxidant and anti-inflammatory properties.


The belief that the bioavailability of Fisetin from dietary sources is moderate may lead to underestimating the challenges in obtaining sufficient levels of this beneficial compound through normal diet alone.

Studies have shown that even with a diet high in Fisetin-rich foods, the body struggles to absorb significant quantities due to its low bioavailability. This underscores the importance of considering supplementation for those seeking its potential health benefits.


In conclusion, the bioavailability of Fisetin from dietary sources is low, which may necessitate supplementation for those seeking its therapeutic effects. Understanding the nuances of nutrient absorption is crucial for maximizing the benefits of a balanced diet.
