What I wanted: Cranberry supplement to treat antibiotic resistant Kidney infection from swimming in unsanitary creek I've used Puritan Pride for years that successfully keeps infection from flare-ups. What I got: Infection flare-up Despite the sale price and wonderful reputation it just didn't work for me. When an infection flares up after changing brands and calming down after going back to old brand, there's not an opinion just stating what happened. I hope this is helpful. Obviously many others have good results but I won't buy it again
