Randomised two group placebo controlled treatment trial of a probiotic - mg orotate formula designed as a treatment for depression. Active condition participants will be administered four capsules daily of a probiotic formula for the entire study duration which are a combination of (20 bill CFU / day for 8 weeks duration along with magnesium orotate (1600 mg / day) or placebo taken as divided into both morning and evening doses. Participants can decide weather they take them with or without a meal. The probiotic strains to be tested are Lactobacillus acidophilus, Bifidobacterium bifidum, and Streptococcus thermophiles. Each capsule contains 5 billion CFU of probiotic bacteria as well as 25.5mg magnesium salts attached to 400mg of orotate. Adherence to the dosage schedule will be monitored by participant completed dosage logs and research assistant follow up to monitor conformity to the protocol. The product to be tested has the commercial name NRGBiotic and is developed and supplied by Medlab Australia.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will not be aware of allocated conditions, and randomisation and allocation will be conducted by a statistician who is not part of the the CI team.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The statistician will provide blinded block randomisation for the allocation of participants equally to the control and experimental groups.
