Description of intervention(s) / exposure
Swisse Women's Ultivite Multi-Vitamin Mineral & Anti-Oxidant with Herbs Formula 1 Dietary Supplement (ARTG Entry 134520) is taken by 40 women, and placebo is taken by 40 women. Swisse Men's Ultivite Multi-Vitamin Mineral & Anti-Oxidant with Herbs Formula 1 Dietary Supplement (ARTG Entry 134521) is taken by 40 men, and placebo is taken by 40 men. There are hence four treatment groups in total. For all treatment groups 1xTablet is taken daily over a 4 month (16 week) period. A subset of participants (20 females receiving placebo and 20 females receiving Ultivite, as well as 20 males receiving placebo and 20 males receiving Ultivite) will be given mobile phones for weekly cognitive and mood testing from home. Another subset of participants (20 females receiving placebo and 20 females receiving Ultivite, as well as 20 males receiving placebo and 20 males receiving Ultivite) will have EEG/SST brainwave recording at each of the study visits baseline, 2 months and 4 months.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will respond to advertisements and pass a phone screen before coming in for their screening and enrolment. Participants will be allocated a participant number that will be assigned to a treatment code. Participants in male and female groups will be randomly allocated to either active or placebo using a computerised random number generator. The products used in this study will be coded A and B for females or C and D for males. The person who determined if a participant was eligible for inclusion in the trial was unaware, when this decision was made, to which group the participant would be allocated. Allocation was concealed by numbered containers.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be allocated a participant number that will be assigned to a treatment code. Participants in male and female groups will be randomly allocated to either active or placebo using a computerised random number generator.The products used in this study will be coded (A, B, C and D).

Summary
Brief summary
Participants attend Swinburne University Hawthorn for one practice visit where they go through the screening questions and provide informed consent. They also practice all cognitive and mood tasks that they will be doing on their subsequent testing sessions. They are then randomised to receive either the multivitamin treatment or placebo for 4 months. Participants come in for 3 testing sessions, the first one week later (V1), the second 2 months later (V2) and the third and final visit after 4 months (V3). At each testing session they complete congitive and mood assessments, together with blood flow, arterial stiffness, saliva cortisol, sleep quality and blood biomarker assessments. A subset of participants (40 males and 40 females) will also complete weekly cognitive and mood tests from home using mobile phones provided. Another subset of participants (40 males and 40 females) will also complete Steady State Probe Topography (SST) brainwave recording at Baseline, V2 and V3.
