Outcome Measures

Primary Outcomes (3)

  • Depression score

    change from baseline at week 4

  • gamma-aminobutyric acid (GABA)

    Blood levels of the neurotransmitter GABA

    change from baseline at week 4

Secondary Outcomes (3)

  • metabolic syndrome

    change from baseline at week 4

  • Inflammation

    change from baseline at week 4

  • LPS

    change from baseline at week 4
