We are looking for individuals living in Adelaide, Brisbane and Sydney that suffer from recurrent UTIs to participate in a study investigating the benefits of cranberry supplementation.


The consumption of cranberries (Vaccinium macrocarpon) has long been investigated as a potential therapeutic intervention for the prevention of recurrent UTI. While the mechanism remains unclear, cranberries contain a number of bioactive components that are suggested to contribute to good urinary tract health. However, despite a large amount of research, little consensus exists. This inconsistency may be due to the type of cranberry product being tested.

In this study, we will be testing a high strength cranberry supplement obtained using the whole fruit. Most other Cranberry products use components of the cranberry. By using the whole fruit, this may ensure no potentially bioactive component of cranberry is lost through manufacturing.

About this study

The aim of this research study is to investigate the effect of daily consumption of a high strength cranberry supplement for the prevention of recurrent UTI in at risk women. Participants will be required to attend a clinic in your city (Adelaide, Brisbane or Sydney) to have blood and urine samples collected.

On completion of the study, participants will receive a Coles/Myer gift card valued at $500 to acknowledge their valuable contribution to scientific research.
