Cranberries and a Happy Bladder: What’s the Connection?

Cranberries and a Happy Bladder: What’s the Connection?

This article examines a recent study on cranberry juice and its potential to help prevent recurring UTIs, especially for women, compared to other treatments.


A new study highlights the benefits of cranberry juice, emphasizing its contribution to protecting against recurring urinary tract infections (UTIs). The benefits of cranberry juice have been known anecdotally in folk medicine, but this study attempts to validate these benefits scientifically. Conducted in Finland, the study focused on the effectiveness of cranberry juice consumption compared to the use of Lactobacillus rhamnosus probiotics.

The study’s findings were published in a recent issue of the British Medical Journal.

Recurring UTIs can significantly impact a person’s quality of life, particularly for women.

This condition is more prevalent among women due to anatomical factors. Estimates suggest that approximately 300 million people worldwide suffer from UTIs annually. These infections are typically treated with antibiotics; however, experts suggest that antibiotics can exacerbate the problem.

Around 60% of women experience a UTI at some point in their lives, with UTIs being among the most common infections in the urinary tract. In about 90% of cases, the cause is Escherichia coli (E. coli). Roughly a third of women will experience a UTI by the age of 24, which can significantly impact their lives.

Another factor is that urinary tract infections are more common among women aged 25 or those over 55. Cranberry juice and products containing the beneficial bacteria Lactobacillus may help reduce the activity of E. coli.

The study involved 150 women previously affected by UTIs. Not all participants responded to antibiotics. One third of the women drank 50 ml of cranberry juice daily for six months, while another third consumed a Lactobacillus product. The remainder did not receive any treatment.

In each instance of UTI symptoms (such as painful urination, blood in the urine, frequent urination, lower abdominal pain, nausea, or vomiting), a urine sample was taken to check for infection.

After eight months, 16% of the women who consumed cranberry juice experienced another UTI, compared to 39% of those who took Lactobacillus, and 36% of those who received no treatment.

These initial findings regarding the benefits of cranberry juice for preventing UTIs are promising. Studies have shown that cranberry juice can prevent E. coli from adhering to cells, but this effect may not be a definitive solution.

One challenge of this study is that women were aware of the treatment they were receiving, and participants relied on self-reporting symptoms. Therefore, women who did not receive treatment may have reported symptoms more often than women consuming cranberry juice daily, who believed it would prevent infections.

Therefore, the best course of action is to conduct more focused studies to determine if the benefits apply to all women.
