Bests & Worsts Reviews from Amazon

The max suggested dosage of Quercetin is 500mg/day. These capsules are 800mg each, and per the bottle: "Take 2 capsules 20 minutes before meals, twice daily", which is 3200mg/day. Decided to give the 3200mg/day a try for a week, and all my aches went away, but at what cost? Long term use of Quercetin at this high a dosage is possibly tied to permanent kidney damage - will keep my kidneys, and suffer a bit with sore joints and tendons instead. Would like to see others post regarding the suggested max dosage vs this manufactures dosage and what problems, if any, people have had.
