In brief: Yes

It has to do some chemicals in cranberry juice basicay being a natural antibiotic for common bacteria causing UTI's.
maybe it gets concentrated in the urine as its excreted by the body. Hope this helps!

Agree. It changes the PH of the urine which harms some common bacteria. It's important to note if you have kidney disease drinking cranberry juice or other juices contain a lot of potassium which may build up to harmful levels. Talk to your doctor first.

Actually, the theoretical mechanism is that chemicals in cranberries inhibit bacterial attachment to bladder mucosa. Unfortunately, a Cochrane review 2012 showed no effect -- pretty much accepted as valid by most infectious diseases specialists and UTI researchers. But as I said in my own reply, it remains controversial. But at least CJ is harmless, so certainly OK to give it a try!

In brief: Probably not

CJ won't treat or cure urinary tract infection.
Whether it helps prevent UTI in women has been a researched for decades, with consensus that it slightly reduces risk. But a comprehensive, highly respected review of the world scientific literature in 2012 showed no effect. For sure no effect in males. Bottom line: women, drink CJ if you like it, but don't expect miracles; it won't prevent all UTIs.

The mechanism by which CJ was believed to help is that it contains chemicals that block UTI-causing bacteria from sticking to the cells that line the bladder, the first step in starting infection. But the respected "Cochrane review" of the research literature is accepted as valid by most infectious diseases experts. OROH CJ is harmless and tastes good. If it seems to help, by all means use it!

"OROH" should be "OTOH" (on the other hand).
