However, I have read that quercetin is insoluble in water which means that the human body can hardly absorb it. It is soluble in alcohol but it requires pretty large amounts of alcohol and this three times a day. Literature also says it is soluble in alkaline solution but I failed with solving quercetin powder in a solution I made from baking soda. Does this mean it is senseless taking quercetin? I have read about quercetin chalcone ("Aller DMG", "Allergy Support Plus", "Quercenase") which is water-soluble and wonder whether this helps. Could not find any information on the internet so far.
