Fights formation of cancer cells and activates the body’s defense against Alzheimer’s disease. Fisetin targets and eliminates senescent ‘zombie’ cells, which are a key factor in the aging process and the formation of age-related diseases like cancer, Alzheimer’s, and Parkinson’s. It also fights the core cause of allergies with powerful anti-inflammatory effects.

Product details

What is FISETIN?

A key factor in aging is the increase in senescent or “zombie” cells as we age. The buildup of these cells is linked to the onset of age-related diseases such as diabetes, cancer, and dementia. Fisetin possesses the unique ability to aid the body in eliminating these harmful senescent cells. Regular consumption of MASI Premium Fisetin can help combat the accumulation of these cells, thereby bolstering your body’s defenses against age-related conditions like dementia, Parkinson’s, and Alzheimer’s.

Fisetin has been also found to promote apoptosis (or programmed cell death) in cancer cells and suppress their growth. These findings suggest fisetin can initiate cell death in many cancer cells while not harming normal cells.

Fisetin reduces the formation of new blood vessels, slows and can prevent the spread of cancer cells. It can inhibit an enzyme known as matrix metalloproteinase-1 used by cancer cells to spread within the body. Together, these properties help to prevent cancer cells from metastasizing and affecting nearby tissues.

Fisetin has been shown to improve long-term memory, to promote the growth of neurons, decrease oxidative stress on brain tissue, and reduce inflammation in brain cells beneficial in preventing Alzheimer's disease.

Fisetin is a powerful anti-inflammatory supplement that fights the core cause of allergies. According to Harvard’s Professor Alessio Fasano, multiyear research indicates that allergic reactions are not isolated events but symptoms of a broader, systemic inflammatory process within the body. By addressing inflammation at its source, Fisetin helps reduce allergic responses while also supporting overall health.

✓ Fight formation of cancer cells

✓ Eliminates "zombie" cells that contribute to aging

✓ Protects DNA from cellular damage

✓ Reduces bodily inflammation, promoting longevity

Fisetin, a natural flavonoid falling within the flavonol subclass of flavonoids, is a plant pigment abundant in various fruits and vegetables. It shares structural similarities with other flavonols like quercetin and kaempferol. Fisetin can be found in a range of plant-based foods, including strawberries, apples, persimmons, onions, and cucumbers. Its renowned antioxidant properties make it a valuable ally in neutralizing detrimental free radicals within the body, which can otherwise harm cells and contribute to diseases.

Beyond its antioxidant prowess, fisetin has garnered attention for its potential to support healthy aging, bolster brain health, enhance cardiovascular well-being, and more. Fisetin is readily available as an anti-aging supplement typically offered in the form of a concentrated extract of this natural compound. These longevity supplements are meticulously crafted to deliver a convenient and consistent source of fisetin, enabling individuals to tap into the remarkable health benefits associated with this flavonoid and potentially reverse aging effects.

Dosing
One capsule contains 250 mg of fisetin. A two-capsule serving provides 500 mg.

Recommended dosage:
40-50 years - 1 capsule per day;
50 years and more - 2 capsules per day

Serving & supply

Each jar contains 60 capsules. One capsule contains 250 mg fisetin. Two capsules provide 500 mg and a 30-day supply. One capsule daily gives up to 60 days of supply.

Fisetin Benefits
Fisetin has gained a lot of attention for its function as a senolytic compound. Senolytics are drugs or compounds that selectively target and eliminate senescent ‘zombie’ cells, which are cells that have stopped dividing and are no longer functioning properly. These cells can accumulate in the body with age and contribute to inflammation and age-related diseases.

Studies have shown that fisetin may help selectively eliminate senescent cells in mice and improve markers of health and longevity. For example, a study published in the journal eBioMedicine found that fisetin supplementation in mice improved physical function, reduced markers of inflammation, and increased lifespan1. Of the 10 flavonoids tested, fisetin was the most potent senolytic.

In addition, there are several other pathways in which Fisetin may help support healthy aging:

Chronic inflammation has been linked to a variety of age-related diseases, and fisetin has been shown to help reduce inflammation in the body2–4.

Fisetin is a powerful antioxidant, which means it helps to neutralise harmful free radicals in the body that can damage cells and contribute to aging. Fisetin functions, at least in part, via interactions with redox signalling pathways, and modulation of the NF-κB, Nrf2, MAPK and PI3K/Akt signalling pathways5,6.

Fisetin has been shown to help support healthy cellular function and to protect DNA from damage7,8, which can contribute to cellular aging and disease.

While the exact mechanisms by which fisetin may increase longevity are still being studied, it is clear that this natural flavonoid has a variety of health benefits that support healthy aging.

Improving health and longevity depends on individual factors such as age, diet, and lifestyle. To maximise the benefits of our supplements, we recommend incorporating them into a comprehensive anti-aging regimen that includes healthy eating, regular exercise, and other lifestyle factors that promote longevity and healthy aging.

What is Fisetin?

Fisetin, a flavonoid naturally present in fruits like strawberries. Its origin from plants has led to research on its anti-aging applications. One of its key functions is the reduction of senescent cells, which are linked to aging and degenerative diseases. Studies indicate fisetin can extend lifespan in certain models by up to 10%, emphasizing its role in aging.

Additionally, it acts as a potent antioxidant, addressing oxidative stress, a major factor in the aging process. It also supports brain health, potentially reducing the incidence of neurodegenerative conditions. David Sinclair, a renowned longevity scientist, incorporates 500mg of fisetin into his supplement regimen, highlighting its importance in promoting healthy aging. Fisetin's multifaceted approach to aging, from senescent cells also known as "zombie cells" that no longer divide but accumulate as we age, causing various health issues. It's like a cleanup crew, removing these cells to promote healthier aging.
