Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1:
Brain & Body Protein Powder
Participants will be required to consume 1 x 30g serve of Brain & Body Protein Powder per day. Each serve is to be mixed with around 200ml water and consumed 90 minutes prior to bedtime. Participants consume the intervention daily for 7 days.

Compliance will be monitored throughout the study. Participants will be assisted with this process through the completion of a consumption calendar that requires them to mark off each serving at time of its consumption. Participants who consume less than 80% of the required product throughout the duration of the study (equal to more than 1 missed serve) will be excluded from final analysis.
Intervention code [1] 327564 0
Treatment: Other
Comparator / control treatment
The trial intervention will be compared to a rice-starch placebo control. The active and control intervention products will be packaged in identical containers. Participants will be required to consume 1 x 30g serve of powder mixed with 200ml water per day 90 minutes prior to bedtime.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Sealed opaque packages will be used to conceal allocation. Study staff will be blinded to group allocations.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Eligible participants will be assigned to interventions using block randomisation. The randomisation scheme will be computer generated.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes

Type of endpoint/s
Efficacy
Statistical methods / analysis
We performed a repeated measures power analysis for a between factors effect to determine the minimum sample size required to detect a medium-to-large effect of the current intervention on LSEQ QoS scores (Effect size F(v)= .50; alpha = .05; beta=.80; r=.60). The minimum number of participants required to detect this effect is n=34. Therefore, we aim to enrol n=40 participants allowing for 15-20% attrition to achieve this number at study endpoint
There are no planned interim analyses of any study outcomes. It is envisaged that analysis will focus on generalised linear mixed models. Outcomes will be assessed at the Intention To Treat level, with sensitivity models conducted using the per-protocol sample. All primary and secondary outcomes will be compared between the study groups. The primary analyses will involve 2-way comparisons between the dairy product group and the placebo control group.
