There were no overall effects from antioxidant vitamins , inositol or dietary minerals on psychiatric symptoms .
There is preliminary evidence that certain vitamin and mineral supplements may reduce psychiatric symptoms in some people with schizophrenia .
BACKGROUND When used as an adjunctive with antipsychotics , certain vitamins and minerals may be effective for improving symptomatic outcomes of schizophrenia , by restoring nutritional deficits , reducing oxidative stress , or modulating neurological pathways .
Vitamin-mineral treatment of attention-deficit hyperactivity disorder in adults: double-blind randomised placebo-controlled trial.
BACKGROUND The role of nutrition in the treatment of  attention-deficit hyperactivity disorder ( ADHD )  is gaining international attention ; however , treatments have generally focused only on diet restriction or supplementing with one nutrient at a time . AIMS To investigate the efficacy and safety of a broad-based micronutrient formula consisting mainly of vitamins and minerals , without omega fatty acids , in the treatment of ADHD in adults . METHOD This double-blind r and omised controlled trial assigned 80 adults with ADHD in a 1:1 ratio to either micronutrients  ( n = 42 ) or  placebo ( n = 38 ) for 8 weeks ( trial registered with the Australian New Zeal and Clinical Trials Registry : ACTRN12609000308291 ) . RESULTS Intent-to-treat analyses showed significant between-group differences favouring active treatment on self- and observer- but not clinician-ADHD rating scales . However , clinicians rated those receiving micronutrients as more improved than those on placebo both globally and on ADHD symptoms . Post hoc analyses showed that for those with moderate/severe depression  at baseline , there was a greater change in mood favouring active treatment over placebo . There were no group differences in adverse events . CONCLUSIONS This study provides preliminary evidence of efficacy for micronutrients in the treatment of  ADHD symptoms in adults , with a reassuring safety profile
