Doctor’s Best Fisetin with Novusetin contains a naturally sourced flavonol that displays positive effects on brain cells and cognitive function pathways in preclinical research. Fisetin is a bioflavonaid antioxidant that can help maintain glutathione levels and mitochondrial function in the presence of oxidative stress.
It has the potential to cross the blood brain barrier, which may help maintain neuronal function. Other than strawberries, fisetin is scarce in fruits and vegetables compared to other flavonoids, making Doctor’s Best Fisetin a most reliable source of this powerful antioxidant and potential nootropic.*

What is Doctor’s Best Fisetin featuring Novusetin?
Doctor’s Best Fisetin featuring Novusetin is a naturally sourced flavonol that supports healthy aging of the brain. 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. Novusetin is a reliable source of this powerful antioxidant.
How does it work?
Fisetin can support the body’s antioxidant pool, both through direct radical scavenging activity and through enhancement of glutathione levels. In vitro research suggests that fisetin can support the body’s glutathione, a very active antioxidant found naturally in the human body, levels by supplying cysteine—a building block of glutathione —to cells, or by enhancing glutathione synthesis. Fisetin may help to regulate production of many proteins involved in protecting the body from oxidative stress and in maintaining redox homeostasis (the balance between rates of free radical production and rates of removal by various antioxidants).
Why should I take Best Fisetin featuring Novusetin?
Best Fisetin featuring Novusetin offers a naturally sourced flavonol that displays many 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.
