Effects of 4 weeks supplementation with a multi-vitamin/mineral preparation on neurocognitive function in healthy adults: A randomised, double-blind, placebo controlled trial
Swinburne University
130 participants

Interventional
Conditions
Summary
The aim of this study is to investigate the effects of 4 weeks of supplementation with a multivitamin and mineral preparation on brain activity and health as measured by cognitive function, mood, and nutritional status. The study will recruit healthy adults, aged 18-40 years, who will attend two testing sessions, one baseline and one after 4-weeks supplementation. During testing sessions participants will complete a series of common assessments including nutritional status, mood and cognitive assessment. A sub-sample will go on to complete an MRI assessment to explore changes in brain activity. The trial will test the predictions that 28-days treatment with the active multivitamin/mineral intervention will result in improved mood, increased functional brain activity, and improved cognitive performance under cognitive demand, when compared to those receiving placebo.

Interventions
Participants will be randomly assigned to one of the following treatments: 1)Berocca Performance (registered trademark) 2)Placebo: Matched for appearance, taste and smell. Treatments will be administered in the form of effervescent tablets. Participants will be instructed to take one tablet daily, dissolved in a glass of water (approx 200 ml) for a duration of 28 days. Treatment adherence will be monitored by the use of a compliance log which participants will take home with them and record the time at which they take their tablet every day. If for some reason they miss a dose, they will be instructed to make a note of this in the log. In addition to the compliance log, participants will also be required to return all unused tablets at the completion of the study so that the experimenter can confirm that the number of tablets they have taken is in agreement with their log. The count of returned treatments will be used for compliance where these measures disagree. Each daily dose of Active treatment (Berocca Performance) contains: Vitamin C 500mg Thiamine Monophosphoric acid ester chloride 18.54mg Riboflavin (Vitamin B2) 15mg Nicotinamide (B3/niacin) 50mg Vitamin B5 23mg Vitamin B6 10mg Vitamin B12 0.01mg Folic Acid (Vitamin B9) 0.4mg Biotin (Vitamin B7) 0.15mg Calcium 100mg Magnesium 100mg Zinc 10mg
