According to the studies, luteolin may help reduce levels of amyloid proteins while simultaneously defending the mitochondria from free radicals, making it a unique, multifaceted product for cognitive nourishment and support. Luteolin is not bioavailable on its own. It requires the presence of other bioflavonoids in order to be metabolized by the body and reach the cells in active form. Luteolin is often accompanied by rutin, which “unlocks” its potential to promote human health. Swanson Ultra Luteolin Complex delivers pure, natural luteolin and rutin in perfect balance for optimal biological benefit.
