When consuming quercetin supplements, always purchase supplements that also pairs it with bromelain as bromelain helps in its absorption and also enhances its properties.
Also always get quercetin supplements in crystalline forms that are encapsulated or even encapsulated liposomal quercetin but never get quercetin in liquid formats as they are highly degradable and its bioactivity is often rendered inactive after days. (Lots of supporting studies on these online)
Also, never buy brands of quercetin made in countries like India, Thailand, Myanmar, Vietnam, Malaysia, Indonesia, Philippines and China as most contain inferior compounds. The best brands for quercetin are Now Foods,Piping Rock, Doctor’s Best, Throne Research and Double Wood. (We do not have any vested interest with these brands nor are we paid any monies by them….wish we were though!..lol!...our recommendations are based on past laboratory analysis of various brands of quercetin)
