What is Fisetin 98%?

Not all forms of Fisetin 98% are equal. The form you choose determines how much Fisetin 98% actually reaches your tissues, and the difference between the best and worst forms can be substantial. This 98% standardized fisetin extract provides the highest purity flavonoid fraction from Rhus succedanea for consistent senolytic and antioxidant activity.

What the Research Shows

Fisetin at 98% purity is a potent flavonoid with emerging evidence as a senolytic — a compound that selectively clears senescent (zombie) cells. Research from the Mayo Clinic and Scripps Research demonstrates senolytic activity at achievable oral doses. It also supports healthy inflammatory response via NF-kB and mTOR pathway modulation. One of the most promising longevity-research compounds.
