Chronic Fatigue Syndrome (CFS/ME/SEID) is a complex and challenging condition that affects millions worldwide, characterized by extreme fatigue, sleep abnormalities, and other debilitating symptoms. Those affected search desperately for any form of relief.
Fisetin, a lesser-known, naturally occurring flavonoid found in various fruits and vegetables such as strawberries, apples, and grapes, is emerging as a potential natural remedy for managing the symptoms. This flavonoid has shown promising results in various studies for its ability to modulate biological pathways that could be linked with the symptoms of Chronic Fatigue Syndrome.
In this article we’ll uncover why Fisetin might just be the next big thing in combating Chronic Fatigue Syndrome.
Understanding Fisetin as a Supplement for Chronic Fatigue Syndrome
Fisetin: A Potential Natural Remedy
Fisetin has been studied lately for its health benefits, including its anti-inflammatory, antioxidant, and neuroprotective properties. These capabilities make it a candidate for addressing some of the underlying issues associated with CFS/ME/SEID, such as oxidative stress and inflammation. By potentially enhancing cellular function and reducing inflammation, Fisetin could help alleviate the fatigue and cognitive dysfunction associated with the condition.
Mechanisms of Action of Fisetin
Fisetin operates through several mechanisms that could potentially benefit people suffering from Chronic Fatigue Syndrome. Its primary actions include:
Anti-inflammatory effects: Fisetin has been found to inhibit several pathways responsible for inflammation. By reducing the production of inflammatory cytokines such as TNF-alpha and IL-6, Fisetin can potentially decrease systemic inflammation associated with CFS.
Antioxidant properties: This compound also combats oxidative stress by neutralizing free radicals — unstable atoms that can damage cells, leading to inflammation and illness. This not only protects cells but also improves cell function and longevity.
Senolytic activity: Remarkably, fisetin has been observed to target and eliminate senescent cells. These are cells that have stopped dividing and contribute to aging and many chronic diseases. By clearing these cells, fisetin can potentially reduce the cellular contributors to fatigue and malaise experienced by CFS patients.
Modulation of mitochondrial function: Mitochondria are the energy-producing centers of cells. Fisetin has been shown to enhance mitochondrial function, potentially increasing energy production. For CFS patients, this could mean improved energy levels and reduced fatigue.
Neuroprotective effects and cognitive function improvement: The flavonoid has shown the ability to protect neurons from toxicity and stress by modulating pathways associated with neuronal survival and death. By protecting the brain cells and enhancing nerve function, Fisetin can help improve cognitive functions and mood, both of which are frequently compromised in chronic fatigue syndrome.
How Fisetin Reflects on CFS Symptoms
The impact of Fisetin on CFS symptoms can be quite comprehensive due to its multi-faceted biological activities:
- Reduction in fatigue: By enhancing mitochondrial function and reducing oxidative damage, Fisetin might directly contribute to alleviating the profound fatigue that characterizes CFS/ME/SEID.
- Improved cognitive function: CFS often involves cognitive impairments. Fisetin’s anti-inflammatory and antioxidative actions might protect neural cells, potentially improving memory, focus, and processing speed.
- Decreased muscle pain: The anti-inflammatory effects of Fisetin can also extend to muscle tissue, potentially reducing the widespread pain that many Chronic Fatigue patients experience.
- Improved mood and sleep: It modulate serotonergic and noradrenergic systems, leading to increased levels of serotonin and noradrenaline, which can help alleviate symptoms of fatigue, depression and sleep disturbance.

The Science Behind Fisetin’s Mechanisms
How does Fisetin work to reduce oxidative stress in chronic fatigue syndrome?
Fisetin demonstrates its efficacy as an antioxidant by not only counteracting free radicals but also stimulating the synthesis of other endogenous antioxidants within the cellular environment through several mechanisms:
Antioxidant properties: Fisetin has direct antioxidant activity that can help neutralize reactive oxygen species (ROS) and reduce oxidative damage. It increases the concentrations of antioxidant components like glutathione and catalase.
Inhibition of lipid peroxidation: Fisetin has been found to inhibit lipid peroxidation, a process that generates oxidative stress. By preventing lipid peroxidation, Fisetin can help maintain the integrity of cell membranes and reduce oxidative damage.
- Modulation of antioxidant enzymes: Fisetin can upregulate the expression of antioxidant genes like catalase (CAT), superoxide dismutase 1 (SOD1), and heme oxygenase 1 (HO-1). By enhancing the activity of these enzymes, Fisetin helps boost the body’s natural antioxidant defenses.
- Reduction of ROS levels: In animal studies, Fisetin treatment significantly reduced ROS levels in hypertrophic hearts and cardiomyocytes. By directly lowering ROS production, Fisetin can help mitigate the damaging effects of oxidative stress.
- Activation of the Nrf2 pathway: Fisetin has been shown to activate the Nrf2 pathway, a master regulator of antioxidant responses. By upregulating Nrf2 and its target genes, Fisetin can enhance the body’s ability to combat oxidative stress.
- Gluthation synthesis:In a particular study conducted on cells, fisetin was observed to elevate the levels of glutathione, a potent antioxidant that aids cells in safeguarding against free radicals and other detrimental reactive oxygen species.
What Makes Fisetin Effective in Combating Inflammation in CFS?
Fisetin, a flavonoid found in fruits and vegetables, has been shown to inhibit inflammation in chronic fatigue syndrome (CFS/ME/SEID) through several mechanisms:
- Suppression of NF-κB and ERK1/2 signaling pathways: Fisetin suppresses the activation of NF-κB and ERK1/2 signaling pathways, which are key regulators of pro-inflammatory gene expression.
- Inhibition of pro-inflammatory cytokine production: Fisetin reduces the production of pro-inflammatory cytokines such as IL-1β, IL-6, IL-8, TNF-α, and CCL5, which are involved in the inflammatory response.
- Antioxidant activity: Fisetin’s antioxidant properties help neutralize reactive oxygen species (ROS) and reduce oxidative stress, which can contribute to inflammation.
- Modulation of immune-related signaling pathways: Fisetin inhibits the PI3K/AKT/NF-κB signaling pathway, which is involved in the regulation of immune responses and inflammation.
- Autophagy induction: Fisetin induces autophagy, a cellular process that helps remove damaged or dysfunctional cellular components, which can contribute to the resolution of inflammation.
These mechanisms collectively contribute to fisetin’s anti-inflammatory effects in Chronic Fatigue Syndrome, which may help alleviate symptoms such as fatigue, pain, and cognitive impairments associated with the condition.
What are the potential impacts of Fisetin on mitochondrial function in CFS?
Fisetin appears to have several beneficial effects on mitochondrial function that may be relevant for chronic fatigue syndrome (CFS) patients:
- Fisetin can enhance mitochondrial biogenesisby increasing the expression of key regulators like PGC-1α and TFAM. This leads to increased mitochondrial mass and mtDNA copy number, which are indicators of improved mitochondrial function.
- By suppressing oxidative stress, fisetin helps protect mitochondria from damage. It reduces ROS levels and upregulates antioxidant genes like CAT, SOD1 and HO-1. This helps maintain mitochondrial integrity and function.
- Fisetin may help compensate for mitochondrial dysfunction in CFS by modulating neurotransmitter systems, activating the TrkB signaling pathway, and inhibiting monoamine oxidase (MAO) activity in the brain. This could potentially improve energy metabolism and cognitive function.
- Flavonoids like Fisetin have senolytic activity, meaning they can selectively remove dysfunctional senescent cells. Clearing these damaged cells may help rejuvenate mitochondrial function.
How Does Fisetin Impact Cognitive Function in Patients with Chronic Fatigue Syndrome?
- Modulation of neurotransmitter systems: Fisetin has been shown to modulate serotonergic and noradrenergic systems, which are involved in regulating mood, sleep, and fatigue.
- Fisetin activates signaling pathways such as PI3K/Akt and ERK, which promote neuronal survival and plasticity. Furthermore, it inhibits detrimental pathways like NF-κB, which is involved in inflammation and cell death.
- Activation of the TrkB signaling pathway: Fisetin activates the TrkB signaling pathway, which plays a crucial role in the mechanisms of depression, a common comorbidity in CFS patients.
- Inhibition of monoamine oxidase (MAO) activity: Fisetin inhibits MAO activity in the brain, leading to increased levels of serotonin and noradrenaline, which can help alleviate symptoms of fatigue and depression.
