Approximately 1 in 7 Australians will experience depression in their lifetime. Unfortunately, current treatments available are not always effective in reducing symptoms of depression.

Previous research shows that the balance of bacteria in the gut can directly affect our mood. Probiotics, a type of dietary supplement, have been found to improve the balance of gut bacteria. Therefore, this study is investigating whether probiotics can relieve symptoms in people with depression.

This study seeks men and women who currently suffer from depression. Participants are required to attend study visits at the research site over a 3 month period.
