Considered an effective urinary tract infection remedy by many, today we answer the question – is cranberry juice an effective treatment or prevention solution for UTIs?  In an attempt to decipher fact from fiction, let’s explore the topic that remains a point of contention among scientists, medical providers, and holistic practitioners alike. 

The Potential Benefits of Cranberry Juice

Historically used by North American Indians, cranberries have long been used to treat UTIs and similar infections. But, why these berries helped was a mystery; only until recently have we gathered sufficient data to support some of the UTI-related health claims.  To understand how cranberry may benefit urinary tract health, it’s important to start with the chemical basis of the plant. According to this National Library of Medicine source, each berry contains:   “Cranberries are composed of water (88%), organic acids (including salicylate), fructose, vitamin C (high levels, i.e., 200 mg/kg of fresh berries), flavonoids, anthocyanidins, catechins, and triterpenoids”   Several of these compounds, such as Vitamin C and flavonoids support improved immune function and antioxidative wellness, which may decrease UTI duration and/or risk of infection progression.  Aside from these immune benefits, the primary prevention hypothesis is that key compounds in cranberry (such as proanthocyanidins, or PACs) inhibit the adhesion of certain types of bacteria to the urinary tract walls. Since many UTIs are caused by bacterial strains of E. Coli, without adhesion, the bacteria cannot bind with and infect the mucosal cells before being flushed from the system.  Another UTI prevention consideration is the high level of acidity in cranberry. Acidic conditions are not favorable conditions for many strains of bacteria, and frequent consumption of cranberry can result in heightened acidity within the urinary system.   

Why Cranberry Juice May Not Be Effective

Despite the fact that cranberry compounds can block bacterial binding and increase acidity levels, cranberry juice may be ineffective for a number of reasons. First, after an infection is already established within your urinary tract, it’s too late to take advantage of cranberry’s primary mechanism of action – preventing bacterial adhesion.  It’s also important to consider that the average cranberry drink only contains 10-25% cranberry because the berries are too acidic to consume in their raw form. Furthermore, even juices with higher percentages of cranberry often contain low-quality sources that may contain minimal levels of beneficial compounds.   Additionally, many supermarket cranberry juices are filled with sugar – bacteria feeds on sugar, and sweetened cranberry juice can actually worsen a UTI. With this in mind, if you plan on utilizing cranberry as part of a UTI prevention plan, try to find a high-quality unsweetened brand, or for best results, find a pure cranberry extract or supplement that has verified concentrations of PACs, vitamin C, and other bladder-friendly ingredients.
