The intervention consists of a micronutrient formula called Empowerplus containing 36 ingredients: 14 vitamins, 16 minerals, 3 amino acids and 3 antioxidants. A list of the ingredients can be found on the company’s website, Truehope.com. The dose will be 4 oral capsules twice a day. The design consists of three multiple baseline, 5 per group. Each group starts at a different time from baseline as determined by randomly assigning each person to one of three starting points from baseline (1, 2 or 3 weeks). Each group takes the micronutrients for 8 weeks. Participants are followed 3 months post-trial

Eligibility
Key inclusion criteria

3. Participants must be able to eat at least a snack two times per day, so that the capsules will not be ingested on an empty stomach.
4. Participants meet criteria for elevated anxiety as assessed by the SCARED. They would also require a CGAS score of at least 50.
Minimum age
8 Years
Maximum age
11 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. Neurological disorder involving brain or other central function (e.g., epilepsy, MS, narcolepsy). Purely peripheral neurological problems are not excluded (e.g., Raynaud’s, peripheral diabetic neuropathy).
2. Any serious medical condition for which major medical interventions are anticipated during the duration of the trial.
3. Any participant known to be allergic to the ingredients of the intervention (including ginkgo biloba, germanium sesquioxide, or grape seed) will be excluded.
4. Any known abnormality of mineral metabolism (e.g., Wilson’s disease, haemochromatosis).
5. Any other medication with primarily central nervous system activity, including mood stabilizers. Participants must have been off of these medications for a minimum of four weeks prior to the trial.
6. Participants will be excluded temporarily if they have taken an oral antibiotic in the previous 6 weeks.
7. Any type of nutritional or herbal supplement, known to have a centrally-acting effect, will result in a participant's exclusion. However, participants who have been taking supplements such as echinacea, chondroitin, or glucosamine may enter the study if a) they have been taking these agents for at least one month prior to the study, and b) they continue on these agents throughout the study. We will permit people to take as much as 1 g/day of EPA and DHA combined.
7. Any subject judged clinically to be at serious risk for suicide or violence in the opinion of the researchers.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
the participants will be randomized to one of three start times (1 week, 2 weeks or 3 weeks post baseline). Each participant number (1 thorugh 15) will be assigned to one of three start times, these start times will be concealed in a sealed envelope and opened once the participant has completed baseline and is ready to begin the trial.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
www.randomization.com will be used to randmoize the 15 participants to the three different baselines.
