Take 1–2 capsules per day with a meal containing healthy fats. Alternatively, you may want to explore the Mayo Protocol, which involves taking high doses of fisetin for two consecutive days each month.
Fisetin is fat-soluble, meaning it is better absorbed by the body when taken with a fat source. This can be a meal or a healthy snack, such as avocado, yoghurt, coconut, or extra virgin olive oil.
As fisetin is an antioxidant, we recommend to avoid taking it around periods of resistance exercise or weight training, as it may reduce some of the workout’s positive effects.

The neuroprotective effects of fisetin, a natural flavonoid in neurodegenerative diseases: Focus on the role of oxidative stress – Review
Outcome: The study reviews how fisetin reduces oxidative stress and protects brain cells thereby potentially preventing neurodegenerative diseases.
Summary: Fisetin is shown to diminish oxidative stress and inflammation in the brain, offering protection against conditions like Alzheimer’s, Parkinson’s, and Huntington’s disease. It works by regulating key molecular pathways that reduce oxidative damage and cell death in cells in the brain called neurons.
Fisetin is a naturally occurring plant flavonoid that is found in strawberries, apples, persimmons and cucumbers.
A study published in EBioMedicine demonstrated that Fisetin was the most effective compound among those tested, significantly reducing senescent cell burden in multiple tissues.
Fisetin primarily acts as a senolytic by selectively clearing senescent cells, which are cells that have stopped dividing but do not die. These cells release harmful molecules that promote inflammation and tissue damage. Over time, their accumulation leads to increased age-related inflammation, known as inflammaging.
Fisetin promotes apoptosis (programmed cell death) in senescent cells by inhibiting their overactive survivial pathways making them more susceptible to cell death signals.
While healthy cells also have survival pathways, they rely on them in a balanced way. Senescent cells depend heavily on these overactive pathways to avoid apoptosis. By targeting these exaggerated survival pathways, Fisetin selectively eliminates senescent cells, reducing their build-up and the associated inflammation, while sparing healthy cells.
Fisetin helps control inflammation by blocking specific cellular signals that would otherwise lead to the production of inflammatory molecules. By preventing this chain reaction, fisetin may reduce the activity of inflammatory molecules, which are responsible for triggering inflammation. Additionally, fisetin boosts antioxidant levels, particularly glutathione, to neutralize reactive oxygen species (ROS) and other free radicals, lowering oxidative stress and inflammation.
In a healthy body, senescent cells are cleared efficiently to prevent them from releasing pro-inflammatory signals. Over time cells that are less efficient in DNA repair and protein folding also accumulate damage more readily, which encourages them to become senescent. Also, the immune system weakens (a process called immunosenescence), reducing its capacity to detect and eliminate senescent cells. As senescent cells accumulate, so does chronic inflammation, increasing demand on the body’s resources to combat it, as well as causing cellular damage.
One of the most effective approaches to counteracting aging is clearing senescent cells. Senescent cells release inflammatory molecules and contribute to persistent low-grade inflammation, known as ‘inflammaging.’ Fisetin’s ability to target and remove these cells may reduce inflammation and oxidative damage, improving overall cellular health and increasing resilience to age-related decline.

In a healthy state, most cells replicate a certain number of times and then die to allow for the replacement of old or damaged cells. Senescent cells have stopped dividing but do not die and remain in the body. As we age, these cells can accumulate and release pro-inflammatory substances, leading to inflammation in surrounding cells. Research has shown a direct correlation between the presence of senescent cells and the ageing process.
Yes, in lower dosages of 100 to 200 mgs, Fisetin is safe to take on a daily basis.
Some individuals choose to run Fisetin in high doses for short periods of time and are using dosing protocols based on studies currently being conducted by the Mayo Clinic.
The Mayo Protocol dosages are:
This would be approximately 1,400 mg daily for a 70 kg (154 lb) person.
Both Fisetin and Quercetin are believed to be powerful natural senolytics. Their differences lie in their ‘off-target’ effects or their ability to work elsewhere in the body.
Fisetin is thought to be the most powerful natural senolytic. It may also work to improve various aspects of brain health because of its ability to cross the blood-brain barrier. Quercetin, in addition to being a senolytic, has been shown to regulate blood sugar and help control the release of the chemical in the body responsible for allergic reactions thereby showing promise in helping to control the effects of seasonal allergies.
