Description Quercetin is a natural flavonoid found in small amounts across a wide variety of fruits and vegetables. Whilst it supports various health related benefits, it is most popularly used and researched in the areas of allergy, inflammation, and immune modulation. Quercetin exclusively utilises Quercefit™ to enhance the bioactivity and efficacy of quercetin, and Phytosome™ delivery technology, which has been developed to support the benefits and potential of quercetin. This is achieved through a delivery system which encapsulates the quercetin molecules with a food grade lecithin.
