Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomly allocated to one of four groups:
1. micronutrient + active monitoring
2. micronutrient + mindfulness
3. placebo + active monitoring
4. placebo + mindfulness
The micronutrient intervention will begin first over an eight-week period, followed by the mindfulness intervention over a six-week period beginning week 3 of the micronutrient intervention. This initial eight-week period is the Randomised Controlled Trial (RCT) phase and will be followed by a second eight-week period where all participants receive micronutrients, and those who did not receive the mindfulness intervention in the RCT will now have access to the online program.

Intervention 1: Micronutrient intervention.
Participants will be randomly assigned to receive either a micronutrient formula or a placebo for eight weeks. After eight weeks, all participants will enter into an open-label phase whereby all participants can choose to take the micronutrient formula for another eight weeks. Both the micronutrients and placebo are in powdered form and are to be taken orally (dissolved on the tongue) at one powdered sachet per day (2.6g). The micronutrient intervention is a blend of 36 vitamins, minerals, and amino acids. The formula, Truehope Ultimate Sticks, is being manufactured and donated by Truehope Nutritional Support Ltd. and consists of the following ingredients: Vitamin A (as retinyl palmitate) 0.03 mg, Vitamin C (ascorbic acid) 10.00mg, Vitamin D (as cholecalciferol) 0.60 mcg, Vitamin E (as d-alpha tocopheryl succinate) 4.00 mg, Thiamin (as thiamin mononitrate) 0.30 mg, Riboflavin 0.23 mg, Niacin (as niacinamide) 1.50 mg, Vitamin B6 (as pyridoxine hydrochloride) 0.60 mg, Folic acid 0.02mg, Vitamin B12 (as cyanocobalamin) 0.02 mg, Biotin 0.02mg, Pantothenic acid (as calcium pantothenate) 0.35 mg, Calcium (as chelate) 22.00 mg, Iron (as chelate) 0.23 mg, Phosphorus (as chelate) 14.00 mg, lodine (from pacific kelp) 3.40 mcg, Magnesium (as chelate) 10.00 mg, Zinc (as chelate) 0.80 mg, Selenium (as chelate) 3.40 mcg, Copper (as chelate) 0.12 mg, Manganese (as chelate) 0.16 mg, Chromium (as chelate) 0.01 mg, Molybdenum (as chelate) 2.40 mcg, Potassium (as chelate) 4.00 mg,
Proprietary blend 27.72mg: [Choline bitartrate, DL-phenylalanine, vanadium chelate, citrus bioflavonoids, Inositol, L-glutamine, L-methionine, boron chelate, grape seed extract, ginkgo leaf extract, germanium sesquioxide, nickel chelate]
Other ingredients: erythritol, natural flavors, malic acid.

Adherence to the intervention will be assessed fortnightly with any missed dosages reported via Qualtrics.

Intervention 2: Mindfulness programme.
Participants will be randomly assigned to receive either access to an online weekly mindfulness programme or to active monitoring (treatment as usual) for eight weeks. After eight weeks, all participants in the active monitoring condition will be given access to the mindfulness programme in the open-label phase.
The mindfulness programme is an adaptation of an existing programme; Mindkiwi. The original Mindkiwi programme was created for children with ADHD and their families. The adapted programme for this study is abbreviated (6 weeks instead of 8), and has removed all reference to ADHD in order to make it generic to any child with emotion regulation challenges. It consists of weekly videos to watch which involve interactive activities to promote mindfulness such as meditation, muscle relaxation, and mindful breathing. Participants will be supplied both hard-copy materials (e.g. resources required for activities such as balloons, pens, paper etc) and online materials such as weekly worksheets. These materials have been selected specifically from the original Mindkiwi programme for use in this study.
Participation requires both the child and a nominated parent/caregiver to engage with the mindfulness videos. There are separate videos for child and parent/caregiver which can be completed at a convenient time throughout the week. Participants will have exclusive access to this programme via their unique login to the Mindkiwi website. Engagement for children per week is approximately twenty minutes. Engagement for parents/caregivers per week is approximately thirty minutes.
For participants who are randomly selected to receive this programme, only the micronutrient/placebo formula will be delivered for the first two weeks, after which the mindfulness programme will commence (hence the adapted programme being only 6 weeks instead of 8). This is to allow for the optimisation of brain function before learning takes place.
Adherence to the programme will be monitored by website analytics. Participants must complete modules and click to move on, therefore it is possible to see each participant's progress through the course at any given time. As each week has specific tasks, it will be apparent if participants have not completed the tasks required for that week. It is not possible for participants to skip modules.

Comparator / control treatment
Intervention 1: Placebo controlled.
The placebo is manufactured and donated by Truehope Nutritional Support Ltd. and consists of the following ingredients taken orally at a dose of 1 powdered sachet per day (2.6g):
Erythritol, natural flavours, malic acid

All participants will report on missed doses each fortnight as part of the fortnightly monitoring via Qualtrics.


Intervention 2: Active monitoring
Participants who are not randomised to the mindfulness programme in the Randomised Controlled Trial (RCT) phase will receive active monitoring. This will consist of 'treatment as usual', as they will be continually monitored fortnightly throughout the RCT phase regardless of whether they have been randomised to the micronutrient or placebo condition groups.

Efficacy
Statistical methods / analysis
Power analysis was conducted to determine the sample size required to detect a moderate effect size of d = 0.6, to a significance level of p = .05 at 80% power, using pre- and post-intervention measures. Based on similar previous studies on ADHD (Rucklidge et al., 2018), stress in students (Katta et al., 2023), and emotional dysregulation in children aged 5-10 (under review) which yielded effect sizes of 0.6, 1.25, and 0.54, respectively, an effect size of 0.6 is a reasonable expectation of this study. Results suggested a total sample size of 160 participants, with 40 participants per arm, would provide sufficient power to detect these effects. However this is conservative, as participant progress will be measured at multiple time points (measure-dependent) throughout the RCT, resulting in more power to detect effects compared to a pre-post design.

The repeated measures of the outcomes will be analysed using generalised linear mixed-effects regression models. These models will permit the testing of differences between the four groups (micronutrient + active monitoring, micronutrient + mindfulness, placebo + active monitoring, placebo + mindfulness) over the course of the trial. Possible moderators of the intervention(s) will also be included. These include SES, age, gender, diet, and marital status. Statistical differences between groups will utilise and report an F test. The pooled mean scores (and standard deviations) throughout the trial on each of the primary outcomes will be used to compute estimates of effect size (Cohen’s d). Chi-square analysis/odds ratios will be reported for the CGI-I by group as responder/non-responder. Scores of 1 and 2 will signify responders as ‘much improved’ or ‘very much improved’, respectively. All tests will be two-tailed, with significance levels determined as p < 0.05.

Summary
Brief summary
The study intends to investigate the efficacy of a broad-spectrum micronutrient (vitamins, minerals, amino acids) intervention delivered alongside an online mindfulness programme to help children who struggle to regulate their emotions. The study will be placebo-controlled, meaning that some children will get the active micronutrient formula and others, an inactive placebo formula. Similarly, some children will get access to the mindfulness programme, and others will be actively monitored throughout the trial. By the end of the study, every child will have tried both interventions, including the active formula for those who initially received the placebo. We believe that both interventions, both individually and in conjunction, will help relieve symptoms of emotional dysregulation in children aged 6–10 years old.
