Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomly and equally assigned to two groups (Bacopa monnieri extract and placebo). These groups are named group 1 and group 2, respectively. The research investigators and participants will be unaware of which treatment these groups represent. This computer-generated randomisation structure will comprise 10 randomly permuted blocks, containing 10 participants per block. Participant identification number (1 to 100) will be allocated according to the order of participant enrolment in the study.

Allocation is not concealed
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Permuted block randomisation using a randomisation table created by a computer software. This computer-generated randomisation structure will comprise 10 randomly permuted blocks, containing 10 participants per block.

Masking / blinding
Blinded (masking used)

Efficacy
Statistical methods / analysis
Based on previous studies on herbal treatments for insomnia, we are predicting an effect size of 0.6 compared to placebo. Based on this, a sample size of 72 is required. This gives an 80% chance of finding an effect at a statistical significance of 0.05. In this study, we will be recruiting 50 participants per group (100 participants in total), which should give us a suitable power to find an effect, even after dropouts.

Pre and post analyses will be conducted to determine changes in the following:

1. Bergen Insomnia Scale (BIS)
2. Pittsburgh Sleep diary (total sleep time, time taken to fall asleep, sleep efficiency, sleep quality rating)
3. Functional Outcomes of Sleep Questionnaire (FOSQ-10)
4. Quality of Life Questionnaire (SF-36)
5. Salivary evening cortisol and melatonin concentrations
6. Salivary morning cortisol, DHEAs, immunoglobulin A (sIgA), alpha-amylase, and C-reactive protein (CRP)
7. Salivary fatigue index (Morning, Midday, and Evening)
