This formulation incorporates the highest potency quercetin available, derived from a non-citrus hypoallergenic plant source, and stabilized with additional antioxidants so as not to auto-oxidize (degrade spontaneously). The body may use quercetin to strengthen the mast cells, involved in the release of histamine, potentially inhibiting that activity. In addition, Quercetin has been shown to reduce the production of prostaglandins and leukotrines which are thought to play a much larger role in promoting inflammation than histamine.
