Best Fisetin Featuring Novusetin offers a naturally sourced flavonol that displays positive effects on brain cells and cognitive function pathways in preclinical research. Fisetin is a bioflavonoid antioxidant that can help maintain glutathione levels and mitochondrial function in the presence of oxidative stress. It has potential to cross the blood brain barrier, which may help maintain neuronal function even in the face of factors that contribute to normal age-associated decline in brain function. Other than strawberries, fisetin is scarce in fruits and vegetables compared to other flavonoids, making Best Fisetin Featuring Novusetin a most reliable source of this powerful antioxidant and potential nootropic.

Flavonol antioxidant support for healthy aging

Never received the product. Your delivery service, instead of calling me or the manager of my building to be buzzed in, simply left the package sitting in front of the building by a very traveled sidewalk. Naturally, when someone saw it sitting there, they just simply took it. I registered a complaint with you and requested the product be replaced. I received back a a very perfunctory, "Request Denied." This, of course, because no one in your organization chose to follow up with the delivery service to find out how they so sloppily delivered my package. They, naturally, reported to you that the package had been delivered (if that's what you can call it -- I never saw it and was never notified that it had been left outside of my building). I hope that you will attempt to make this right . . .

Thanks for your feedback!
