## Description

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.
