Frequently Asked Questions

Can You Take Fisetin Everyday?

Although fisetin is typically safe to take in recommended doses, there is still a lack of conclusive evidence on the long-term safety of taking it over an extended period.

To ensure optimal protection and get accurate dosage advice that takes into account any health issues or existing medications you’re using, consulting with a doctor before starting supplementation is strongly advised. Each case can vary greatly, so speaking with your physician about the correct amounts for yourself will be invaluable information!

Source of FisetinIf taken in the correct dosage, Fisetin can be an incredibly beneficial supplement for overall health and wellness. It is believed to reduce senescent cells in the body, along with anti-inflammatory, antioxidant, and neuroprotective effects.

However, it’s vitally important to keep in mind that taking too much of any supplement could potentially have adverse impacts on your well-being.

What is the Best Source of Fisetin?

For a steady supply of Fisetin, eating copious amounts of fruits and vegetables such as strawberries, apples, persimmons, grapes, onions and cucumbers is the best option. However, if you are looking for an alternative source beyond food items then consider taking supplements after consulting with your healthcare professional beforehand.

Fisetin supplements are available in the form of capsules or tablets and contain an extract of the flavonoid fisetin. Fisetin supplements are an ideal source of this essential nutrient for those who have trouble obtaining enough through diet. Although these supplements are generally secure when taken in recommended amounts, it is still advisable to check with a healthcare specialist to ensure the right dosage and safety for your individual needs.

Additionally, further research is essential to gain a comprehensive understanding of the effects that fisetin supplements have on health and how much should be taken.

Can Fisetin Reverse Aging?

Fisetin was the most potent senolytic, it has been found to have the ability to reduce the number of aging-associated and disease-causing cells in our bodies. While research is ongoing, it appears that Fisetin may be able to slow down or even reverse age degeneration. However, there is much more work needed before we can truly understand how powerful this supplement can be when used against premature aging effects.

Anti Aging

Is Quercetin Any Good?

Recent studies suggest that quercetin may have powerful anti-cancer, cardiovascular health, and allergy/asthma relieving properties.

Furthermore, research indicates that it could aid athletic performance and help manage the symptoms of certain chronic diseases. However, further investigation is necessary to better understand its effects and potential for benefiting our health.

Fisetin vs Apigenin

With a powerful combination of positive health effects, Fisetin and Apigenin are two incredibly beneficial flavonoids.

Fisetin boasts possible senolytic powers as well as neuroprotective properties while the latter has been noted to possess anti-inflammatory and cancer-fighting abilities. Incorporate these nourishing compounds into your diet by consuming foods such as strawberries, apples, persimmons, grapes, onions cucumbers, or chamomile tea for optimal well-being!

What is the Most Powerful Senolytic?

The term “senolytics” refers to a class of compounds that target and eliminate senescent cells, which are aged or damaged cells that accumulate in various tissues over time. Among the most potent and studied senolytics is the combination of dasatinib and quercetin. Dasatinib, a tyrosine kinase inhibitor used in cancer treatment, and quercetin, a flavonoid found in various plants, work synergistically to induce senescent cell apoptosis through the disruption of pro-survival pathways. This combination has demonstrated remarkable efficacy in preclinical studies, leading to the clearance of senescent cells and improvement in various age-related pathologies in animal models.

The mechanism of action involves dasatinib’s inhibition of the tyrosine kinase activity that sustains senescent cells, coupled with quercetin’s ability to inhibit the anti-apoptotic protein Bcl-xL. This dual impact triggers apoptosis in senescent cells, promoting their efficient removal by the immune system. The specific combination of dasatinib and quercetin offers a promising approach to addressing age-related diseases and extending the health span. Clinical trials and studies are ongoing to further investigate the safety, efficacy, and potential side effects of this senolytic combination in humans.

It’s important to note that while dasatinib and quercetin have shown significant potential, research in the field of senolytics is still evolving, and other compounds with potent senolytic properties may emerge as our understanding deepens. Nonetheless, the dasatinib and quercetin combination currently stands out as one of the most powerful senolytic interventions studied to date.

Fisetin vs Spermidine

Fisetin and spermidine are two distinct natural compounds that have gained attention for their potential health-promoting properties, particularly in the context of aging and age-related diseases. Fisetin is a flavonoid found in various fruits and vegetables, while spermidine is a polyamine compound that naturally occurs in cells.

Both fisetin and spermidine have been studied for their effects on cellular processes and longevity. Fisetin acts as a senolytic agent, targeting senescent cells and promoting their elimination, which has been shown to enhance tissue function and extend lifespan in animal models. On the other hand, spermidine exerts its effects through autophagy, a cellular recycling process that removes damaged components and supports cellular renewal. Spermidine’s induction of autophagy contributes to improved cellular health and has been associated with increased lifespan in model organisms.

Research has shown that fisetin possesses potent antioxidant and anti-inflammatory properties, which contribute to its potential benefits against neurodegenerative diseases and age-related cognitive decline. Spermidine, through its role in autophagy induction, offers cardioprotective effects, helps regulate metabolism, and may mitigate age-related cardiac issues.

Comparing the two, it’s important to note that fisetin primarily focuses on senescent cell clearance and anti-inflammatory effects, whereas spermidine revolves around autophagy induction and cellular renewal. While both compounds hold promise for extending health span and lifespan, their mechanisms of action differ significantly. Ongoing research aims to unravel their full potential and explore possible synergistic effects when used together or in combination with other interventions.


Although both Fisetin and Quercetin have similar health benefits, their uniqueness lies in their key differences. The bioavailability of Fisetin is lower compared to Quercetin, therefore it requires a higher amount to achieve the same results. Therefore, consulting with a healthcare professional when deciding on dosages for your individual needs is paramount for safety reasons and potentially greater health gains if taking them together.

Fisetin is a favorable plant compound that can be effective in combating osteoporosis, an ailment characterized by bone loss. This bone degradation can result in fractures and weakness due to disruptions in the skeletal tissue’s microstructure.

Osteoblasts are the cells that form your bones and osteoclasts break down those same cells. They rely on each other to keep your bones healthy; however, when you have osteoporosis, there is an imbalance of these two types causing a net loss of bone mass.

Research has uncovered fisetin as a possible solution to this issue by stimulating the work of bone-forming cells while suppressing their breakdown in rats specifically.
