Reload purchase optionsA 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.

Enhanced Cellular Renewal with Spermidine Tied to Age-Well Benefits
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.
