What Research Says

Researchers have been studying the effects of cranberry juice on UTIs over the last few years. Some studies have shown evidence in support of the fact that cranberry juice helps in curbing the adverse effects of UTIs. On the other hand, some counter this argument. Thus far, there has been no concrete evidence in support of the use of cranberry juice for eliminating the problems linked to urinary tract infections.

This is evident from the studies conducted on the subject matter in 2012 and 2013. The study(2) in 2012 indicated the partial efficacy of cranberry juice for UTIs, whereas the one conducted in 2013 showed results in favor of it. However,  due to the lack of any concrete evidence, certified professionals do not consider it as a reliable treatment for urinary tract infections.

Which Type of Cranberry Juice Is the Right Choice for You

In case you use cranberry juice for the treatment of UTI, you must use the right one. Since UTIs occur due to the growth of harmful bacteria in the genital region, it is essential to use a remedy which does not favor its growth in any way. These harmful bacteria thrive in numbers under the influence of sugars and sweeteners.

Therefore, it is vital to make sure that you use cranberry juice, which does not have sweeteners. Natural cranberry juice without sweeteners is the best cranberry juice for UTI.

The same rule applies to cranberry juice, which is taken orally. Drinking cranberry juice that is free from sugar is the safest option. By doing so, you will be able to prevent the growth of the harmful bacteria that are responsible for causing urinary tract infections.

The best part about using cranberry juice for the treatment of UTIs is that it does not have any side-effect. This makes it relatively a safer option than some antibiotics that are used for the treatment of bacterial infection in the urinary tract.

Further, one does not need to worry about exceeding the minimum dosage. Though a dose of 40 mL with at least 25% of cranberry juice is the recommended dosage, exceeding this dose is not known to harm the body in any way.

Though cranberry juice is touted to be an effective solution to treat UTIs, there is no concrete research-based evidence to support the claim. It is believed to have PACs that curb the growth and adherence of the harmful bacteria that are responsible for causing UTIs. Given the lack of any conclusive evidence of the effectiveness of the remedy, it is strongly recommended that you should consult a certified physician before using the treatment.
