WHAT IS FISETIN?

Fisetin (3,3′,4′,7-tetrahydroxyflavone) is a plant flavonol belonging to the flavonoid polyphenol group. It is a yellow plant pigment, with its name originating from a German word (fisetholz) for a traditional yellow dye called “young fustic.” Polyphenols, like fisetin, play important roles in the plant kingdom. One of these roles is protecting plants from environmental stress. Because of this, fisetin is found in many plants, occurring in their green parts, fruits, barks, and hardwood. Fisetin is present in strawberries, apples, persimmon, grapes, onions, and cucumbers, as examples, though in very low amounts. Most of the research on fisetin has focused on its potential to support senolytic mechanisms and neuroprotective functions.* 


NEUROHACKER’S FISETIN SOURCING

Fisetin is produced from the stems of Rhus succedanea (Japanese fruit wax tree), which is the primary commercial source used to make this dietary supplement ingredient. The high-purity standardized extract we use contains not less than 98% fisetin.

Fisetin is non-GMO, gluten-free, vegan, and Kosher and Halal certified.


FISETIN FORMULATING PRINCIPLES AND RATIONALE

We chose the recommended serving of fisetin based on how it is most commonly being dosed in clinical research to support senolytic functions. As an example, in several ongoing studies fisetin is being dosed at 20 mg per kg body weight daily, orally for 2 consecutive days (ClinicalTrials.gov identifier NCT03675724, NCT03430037, NCT04476953, NCT04771611, NCT03325322). The 1400 mg fisetin serving in Qualia Senolytic would correspond to the daily amount being used in these studies for a person weighing approximately 155 pounds (70 kg). The approach to intake recommended (i.e., take for 2 consecutive days followed by 28 days before the next intake cycle) is consistent with the intermittent intake approaches being used in some ongoing studies, and more broadly with the amount of fisetin being recommended by experts in the healthy aging community the Neurohacker science team has been in communication with. Our recommended serving selection also took into account that Qualia Senolytic contains several other ingredients which would be expected to be complementary with fisetin.*
