Bio-Fisetin by Life Extension – Up to 25x Greater Bioavailability – 30 Vegetarian Capsules

Life Extension Bio-Fisetin – Ultra-Bioavailable Fisetin for Senolytic, Longevity & Brain Health Support

Fisetin is a naturally occurring flavonoid found in strawberries, apples, and other fruits — and it has rapidly emerged as one of the most exciting longevity compounds in anti-aging science. Research suggests fisetin acts as a potent senolytic agent, helping to clear senescent (“zombie”) cells that accumulate with age and drive chronic inflammation and tissue dysfunction. Life Extension’s Bio-Fisetin uses a proprietary complexing technology to deliver fisetin with up to 25 times greater bioavailability than standard fisetin supplements — ensuring you get meaningful levels in circulation where the science shows it matters.

What Does Bio-Fisetin Do?

• Acts as a senolytic to help clear senescent (“zombie”) cells that accumulate with aging
• Supports healthy inflammatory balance and reduces senescence-associated secretory phenotype (SASP)
• Promotes cognitive function, memory, and neuroprotection via multiple pathways
• Activates sirtuins and supports NAD+ metabolism for cellular energy and longevity
• Provides potent antioxidant protection at the cellular and mitochondrial level
• Up to 25x greater bioavailability vs. standard fisetin through advanced complexing technology
• Gluten-free, non-GMO vegetarian capsule formula

Who Should Take This?

Bio-Fisetin is ideal for adults focused on healthy aging, longevity, and cellular rejuvenation — particularly those interested in senolytic protocols. It is also well-suited for those seeking cognitive support, antioxidant protection, and healthy inflammatory balance as part of a comprehensive anti-aging supplement stack.

Frequently Asked Questions

What is a senolytic and why does it matter for aging?
Senescent cells are damaged cells that stop dividing but refuse to die — instead they linger and secrete inflammatory compounds (SASP) that damage surrounding healthy tissue. Accumulation of senescent cells is a key driver of aging, chronic disease, and tissue dysfunction. Senolytics like fisetin help selectively clear these cells, potentially slowing the aging process at a fundamental level.

Why does bioavailability matter for fisetin?
Standard fisetin has poor oral bioavailability due to its low water solubility and rapid metabolism. Bio-Fisetin’s Novusetin™ complex dramatically improves absorption, achieving blood levels up to 25x higher than conventional fisetin — which is critical for achieving the concentrations shown to be effective in research.
