    More Info.

    Quercetin belongs to a class of water-soluble plant pigments called bioflavonoids that cannot be produced in the human body. In a clinical study, subjects who supplemented with formulated Quercefit® Quercetin Phytosome had significant improvements in oral absorption compared to unformulated quercetin. Douglas Laboratories Querciplex provides 250 mg of highly bioavailable and soluble Quercetin Phytosome, which has been shown to increase peak plasma quercetin levels by 20-fold compared to standard quercetin.

    This formulation also includes bromelain, a pineapple stem extract. Both quercetin and bromelain offer support for respiratory and immune health. Several studies show that supplementation with quercetin or bromelain supports mast cell function through interleukin modulation. Additionally, an in vitro study performed on neutrophils reported that quercetin moderated interleukin-6 release in response to an immune trigger.
