THP Fisetin 100mg, 98% Pure Smoke Tree Extract for Cellular Health and Antioxidant Support

The Health Project Fisetin is a high-purity plant polyphenol supplement in capsule form. Each capsule delivers 100mg of Fisetin at 98% purity, extracted from Smoke Tree (Cotinus coggygria). The 90-capsule bottle provides 90 single-capsule servings.

Fisetin is a flavonol found naturally in strawberries, apples and onions. It has attracted significant research interest across several longevity and cellular health mechanisms: it activates the Sirtuin 1 deacetylase pathway involved in cellular stress resistance and mitochondrial biogenesis; it has demonstrated senolytic activity in vitro and in animal models, selectively inducing apoptosis in senescent cells while sparing healthy cells; it activates Nrf2, the master antioxidant transcription factor driving glutathione synthesis and phase-II detoxification enzyme expression; and it crosses the blood-brain barrier where it provides neuroprotective effects through reduction of neuroinflammation. The Smoke Tree source is the highest-fisetin-density botanical available commercially.

What separates THP Fisetin from a general antioxidant capsule is the senolytic mechanism. Standard antioxidants neutralise reactive oxygen species extracellularly or cytoplasm-wide. Fisetin selectively targets senescent cells for clearance - a mechanistically distinct intervention relevant to cellular health maintenance and longevity science that standard antioxidants do not address.

THP Fisetin suits health-optimising individuals interested in longevity pathway support, athletes looking to support cellular health and mitochondrial function, and anyone researching evidence-emerging plant polyphenols for comprehensive wellness protocols. It is not a medical treatment and should not be interpreted as such. Contains no major allergens.

Frequently Asked Questions

What is fisetin and what is it used for?

Fisetin is a flavonoid naturally found in fruits like strawberries, apples and persimmons. Research has explored its role in cellular senescence and antioxidant pathways. THP Fisetin uses 98% pure fisetin from Smoke Tree Extract for a transparent dose per serving.

What is the difference between fisetin and quercetin?

Both are flavonoids with antioxidant properties, and both have been studied for potential senolytic effects. Fisetin is found primarily in strawberries and smoke tree, while quercetin is found in onions, apples and green tea. Some people take both as part of a longevity stack since they work through slightly different mechanisms. THP Fisetin is a standalone option for people who want to add fisetin specifically to their routine.

Can I stack THP Fisetin with THP Resveratrol and Apigenin?

Yes, all three are individual polyphenol and flavonoid supplements from the THP range, and they are commonly combined in longevity-focused stacks. Fisetin provides senolytic and antioxidant support, resveratrol is studied for cardiovascular and supports a normal inflammatory response effects, and apigenin supports relaxation and sleep. Taking all three gives you a broad polyphenol profile from separate, clearly dosed capsules.
