The Claim
In adults with schizophrenia and metabolic syndrome receiving antipsychotic medication, adjunctive administration of berberine at 600 mg per day for 12 weeks has no significant effect on psychotic symptoms as measured by the Positive and Negative Syndrome Scale compared to placebo.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults with schizophrenia and metabolic syndrome taking antipsychotic drugs, taking berberine at 600 mg daily for 12 weeks does not change the severity of psychotic symptoms compared to taking a placebo.
See the scientific wording
In adults with schizophrenia and metabolic syndrome on antipsychotics, adjunctive berberine (600 mg/day for 12 weeks) does not worsen psychotic symptoms, as measured by the Positive and Negative Syndrome Scale, compared to placebo.
Berberine helps the body process sugar and fat better by turning on a key energy sensor in the liver and muscles, which lowers blood sugar and fat levels. This improvement in metabolism does not interfere with the brain chemicals that control thinking and perception, so psychotic symptoms stay the same.
What the research says
1 studyThis study gave people with schizophrenia berberine pills for 12 weeks while they kept taking their antipsychotic meds, and found their psychosis didn’t get worse—same as those who took a sugar pill.
