The Claim

In adults with schizophrenia and metabolic syndrome on antipsychotic medication, adjunctive administration of berberine at 600 mg/day for 12 weeks reduces body mass index by 0.41 kg/m² compared to placebo, with a large effect size (d=0.64), indicating significant improvement in overall adiposity.

In plain English

In adults with schizophrenia and metabolic syndrome taking antipsychotic drugs, taking 600 mg of berberine daily for 12 weeks lowers body mass index by 0.41 kg/m² compared to a placebo, reflecting a measurable reduction in body fat.

See the scientific wording

In adults with schizophrenia and metabolic syndrome on antipsychotics, adjunctive berberine (600 mg/day for 12 weeks) reduces body mass index by 0.41 kg/m² compared to placebo, with a large effect size (d=0.64), indicating significant improvement in overall adiposity.

Why this might work

Berberine triggers a cellular energy sensor that turns off fat production and turns on fat burning and sugar uptake in muscles, causing the body to store less fat and lose weight.

  1. Study: Adjunctive berberine reduces antipsychotic‐associated weight gain and metabolic syndrome in patients with schizophrenia: a randomized controlled trial

    In a study, people with schizophrenia and weight problems who took 600 mg of berberine daily for 12 weeks lost a small but noticeable amount of body fat (measured by BMI) compared to those who took a sugar pill — and it didn’t make their mental health worse.
