  • Project Details

    ARCADIA is a specialised nutraceutical and lifestyle medicine mental health research group within The Professorial Unit based at The Melbourne Clinic. ARCADIA holds collaborations with The University of Melbourne, Swinburne University and the National Institute of Complementary Medicine (NICM) at Western Sydney University. Our vision is to enhance the treatment of mood and anxiety disorders by leading the research of nutraceuticals (pharmaceutical-grade standardised nutrient or plant-based medicines) and lifestyle medicine in the field of psychiatry. The group is part of the broader research unit focusing on the key areas of psychopharmacology, pharmacogenomics, and brain stimulation.

    The  group is conducting several NHMRC-funded double-blind randomised control trials using nutraceuticals in the treatment of mental disorders such as unipolar depression, generalised anxiety disorder, and obsessive compulsive disorder. A major  focus of this research includes the study of pharmacogenomics, to examine genetic markers of treatment response and the prediction of efficacy and tolerability of these agents. We are also passionate about researching the emerging area of lifestyle medicine, and the application of diet, exercise etc. to enhance both physical and mental health.

    Results of our ongoing NHMRC and collaborative industry-funded clinical studies continues to advance the treatment of depressive and anxiety disorders. This research is aimed at enhancing the education and clinical treatment of mental disorders, as well as growing public knowledge of these approaches.
