The dietary flavonoid quercetin exerts protective cardiovascular effects. Because quercetin is rapidly metabolized into less active or inactive glucuronidated metabolites and the plasma concentrations of free quercetin are very low, a huge amount of scientific data generated along decades with the unconjugated compounds in vitro has been questioned. We aimed to determine whether glucuronidated quercetin can deconjugate in situ and whether deconjugation leads to a biological effect.
