Cranberry Juice and Urinary Tract Infections

Cranberries and cranberry juice help reduce urinary tract infectionsThe latest word on drinking cranberry juice to prevent urinary tract infections is that it really does work. Researchers in Taiwan analyzed the data from 13 studies that compared the use of cranberry juice or products containing cranberries to placebos. They found that cranberry juice works better than cranberry supplements and that those who benefited most were women (especially women who had recurrent urinary tract infections) and children. They also found that individuals who consumed cranberry products twice a day received more protection than those who took them less often. The investigators suggested that cranberry juice might be more effective because of the effect of unidentified substances in the juice that aren’t found in cranberry supplements. They concluded that drinking cranberry juice or taking cranberry supplements could reduce the incidence of urinary tract infections in high risk people - pregnant women, the elderly and individuals with under-active bladders due to nervous system damage. The study was published in the July 9, 2012, issue of the Archives of Internal Medicine.

Hey Dr. Weil, first time visitor. Good post. I have to agree with you 100%. My wife was notorious for getting UTI's. We did some research and found that cranberry juice was recommended. She started drinking CJ and low and behold no more UTI's. My wife is proof it works. The only issue is getting use to the taste. My wife loves it. thanks. - kirby

The issue is getting true cranberry juice and not some sugar loaded "cocktail". I have chronic cystitis and have taken cystex 1x daily since diagnosis. I'm not in a hurry to volunteer for another cystoscope, but there has been negative occult blood in my urine since.

Was there anything in the study about whether or not the cranberry drinks consumed had added sugar? It's my understanding that the cranberry "cocktail" drinks contain so much sugar that it overrides the benefits?

Which kind is a healthy cranberry juice, or drink? Most commercial juices have so much sugar in it.

I take a capsule of cranberry supplement every day. It's great. Prevents bacteria from sticking to the urinary tract wall.

Do not drink the cranberry "cocktail" drink for this purpose. You must buy the 100% pure cranberry juice found in the health food aisle of the store. It is quite sour because it doesn't have any added sugar. The taste takes a while to get used to but the juice does work.

I don't like to drink juice so I eat a small handful of dried cranberries. Works beautifully. Also, I keep well hydrated with plenty of water.
