Brief summary
Insomnia is the most prevalent sleep disorder, affecting around 10% of Australians. The symptoms include difficulties getting to sleep, difficulties staying asleep, or early-morning awakenings with an inability to return to sleep. Insomnia may also be associated with problems with memory and attention, and increased feelings of depression, anxiety and stress. Insomnia can be treated effectively without medication, such as cognitive behavioural therapy for insomnia with a psychologist. However, there remain a large proportion of individuals who do not seek help possibly due to barriers such as geographical location or time constraints, or they do not wish to use pharmacological treatments for sleep. Further evidence for alternative therapies for insomnia, particularly those with milder forms of the disorder, are needed. Potential significance of the research project: Insomnia is a highly prevalent but neglected sleep disorder, with serious health consequences for patients and large financial costs to the health system. The use of a supplement for sleep in those with milder forms of the disorder could potentially provide a low cost, widely accessible, and effective treatment solution for people with insomnia across Australia, who would otherwise rely on sleep medication for better sleep. The aim of this project is to conduct a clinical trial to examine the effectiveness of a supplement compared to placebo for improving sleep outcomes in individuals with subclinical insomnia over a four week period. It is hypothesised that the supplement will reduce the severity of insomnia symptoms, and improve subjective and objective sleep quality, quantity, and associated daytime symptoms, compared to placebo.
