The Active Ingredient Is: Fisetin (Novusetin Branded Extract)

Fisetin is a natural flavonol with antioxidant properties that help cellular health and healthy ageing. This formula uses Novusetin, a branded standardised extract, as the fisetin source.

This extract comes from a plant-based source and is designed to provide a steady level of fisetin for supplementation.

What Does Fisetin Do?

Fisetin helps maintain cellular health and may support cognitive function and neuronal protection in line with current research on antioxidant compounds.

EFSA-supported language suggests its role is as part of a broader antioxidant system that supports normal brain and ageing processes, with the formulation including a standardised fisetin extract to assist with these functions.
