Please contact us here if you would like further information about participating or have any questions.

The Bugs and Brains Study aims to better understand the link between mental health and various factors, including diet, early life experience, stress and wellbeing. Whilst we are also interested in learning about the role of the microbiome (i.e., bacteria that live in and on our bodies) in these processes, recruitment for the collection of biological data relevant to bacterial and physiological profiles has now ended. Please click on the Background tab for detailed background information about the study.

Participation in the Bugs and Brains Study now involves the completion of online questionnaires to better understand the relationships between gut health and mental health in the community. Click on the 'Am I Eligible' tab to find out more.
