thank you. I found just the opposite information about people with kidney issues....not just the quercetin, but zinc as well. I am diabetic and many with diabetes have kidney issues so I've got to get this right. EDIT to add: the info I found on WebMD said "Kidney problems: Quercetin might make kidney problems worse. Don't use quercetin if you have kidney problems." BUT the info you provided makes it sound like it would be great for kidneys as well as diabetes and other issues I have. SMH? guess I could just ask GP.
