Urinary Tract Infections And Cranberry Juice

Urinary Tract Infections And Cranberry Juice

Does cranberry juice really make a difference?

We often hear that drinking cranberry juice or taking high strength cranberry products will help support urinary tract health but how true is this and what does the latest nutritional research suggest?

The problem:

Urinary tract infections (UTIs) are pretty common. In fact, around one in 2 women and one in 20 men will get a UTI in their lifetime. UTIs are caused by germs, usually bacteria. UTI symptoms include:

  • wanting to urinate more often and urgently
  • burning pain or sensation when urinating
  • a feeling that the bladder is still full after urinating
  • pain above the pubic bone
  • cloudy, bloody or very smelly urine

Who’s at risk?

  • women – sexually active women are at increased risk as the urethra is four centimeters long – providing a short distance for bacteria to travel from the outside to the inside of the bladder
  • people with urinary catheters
  • people with diabetes
  • men with prostate problems – such as an enlarged prostate gland that can cause the bladder to only partially empty
  • babies & children– especially those born with physical problems (congenital abnormalities) of the urinary system

The evidence:

To cut a long story short, taking oral cranberry products (juice or supplements) may help decrease the risk of recurrent, uncomplicated UTIs among generally healthy non-pregnant women. In saying this, as there is such a wide variety of types of cranberry products and doses, it is impossible to set a recommended dose or product form that is optimal for decreasing UTI risk.

Interestingly, research suggests that there is no evidence to support that taking cranberry is of any help once a UTI has already developed. Unfortunately, when it comes to decreasing the risk of complicated UTIs among those most vulnerable, the research is quite inconsistent.

Here’s a summary:

  • The overall benefit of cranberry for UTI prevention is mostly lacking among pregnant women, elder or older adults and those with neurogenic/neuropathic bladder. BUT…
  • There was some evidence of some decreased risk among children and adolescents and those undergoing pelvic radiation therapy.
  • For those keen to try cranberry for UTI prevention it is important to note that a benefit has not always been seen (there is some inconsistency in research trials)

Cranberry Nutrition


Cranberries are high in antioxidants, specifically Vitamin C, Vitamin E and Quercetin which help protect against free radical damage. When it comes to UTIs and cranberries, cranberries possess anti-adhesion qualities, which help reduce the adhesion of bacteria to the urinary tract.

Cranberry Juice

As with any juice these days, if you do want to try cranberry juice for UTI prevention, be sure to read the packaging and ingredients list. Ideally, you want to go for a cranberry juice without added sugars and something made with “100 percent real juice.” Look for natural sweeteners on the ingredients list, like apple or grape juice.

Cranberry Supplements

Some cranberry supplements are now using the whole fruit of the cranberry fruit, which is known to help further support urinary tract health. By using the whole fruit, this also increases polyphenols and fibre intake. Win win?!

Other considerations?

  • The calorie, sugar and potassium content of cranberry juice is an important consideration for some people, depending on health goals and medical conditions
  • As always, the financial cost of supplements & juice is another consideration when considering the risk benefit ratio of trying cranberry for UTI prevention
  • Some people find cranberry juice to cause or worsen reflux
  • Some supplements are using the whole fruit of the cranberry – this might be a good thing to consider if you’re at the chemist trying to decide between brands/products

Our Story

In 2004, Gen McGlashan and Libby Oldfield founded Fitwise Physiotherapy. They first met in 1994.  Libby was Gen’s physio when she had her first child. Gen then worked for Libby for 10 years in Libby’s previous business, located at the Epworth Freemasons Maternity Unit in East Melbourne. They have been a team working together for a very long time!!

Libby and Gen have always had a passion for empowering women, by helping provide accurate evidence based information and treatment to help women live their best lives. Excellence in all that they do, practising and operating in an innovative way has always been their core. Fitwise was the first multi-practitioner practice providing Women’s Health physiotherapy consultations, exercise classes and clinical pilates in Melbourne.

Gen and Libby

In February 2005 Gen and Libby moved their one room practice to Albert St East Melbourne. They had expanded to 2 treatment rooms, an exercise studio and a pilates studio with a small team of physiotherapists and one receptionist. This was exciting as they wanted to be able to help more people and to grow their team – enabling their other passion: teaching and mentoring clinicians who also wanted to work within the Women’s, Men’s and Pelvic Health arena.

5 years later, they expanded their East Melbourne clinic and in 2015 opened their second clinic in Armadale.

Remedial Massage, Myotherapy and Dietetics have been an exciting addition in recent years, with Podiatry and Exercise Physiology being added in 2022.

The Fitwise team has now grown to include 18 amazing practitioners and 12 wonderful administrative team members and is still growing!

Libby and Gen have always loved providing a holistic service, treating a variety of conditions in consultations and providing exercise appropriate for different life stages. The community of clients that are part of the Fitwise family, (some who have been part of the journey from the very beginning – over 17 years ago), are the biggest reason they do what they do. For Gen and Libby, it is a privilege to be part of these wonderful people’s lives.
