The Claim

In adults with schizophrenia and metabolic syndrome on antipsychotics, adjunctive berberine at 600 mg/day for 12 weeks reduces glycated hemoglobin (HbA1c) by 0.09% compared to placebo, with a small-to-medium effect size (d=0.37), indicating modest improvement in long-term glucose control.

In plain English

In adults with schizophrenia and metabolic syndrome taking antipsychotic medication, taking 600 mg of berberine daily for 12 weeks lowers HbA1c by 0.09% compared to a placebo, showing a small-to-medium improvement in long-term blood sugar control.

See the scientific wording

In adults with schizophrenia and metabolic syndrome on antipsychotics, adjunctive berberine (600 mg/day for 12 weeks) reduces glycated hemoglobin (HbA1c) by 0.09% compared to placebo, with a small-to-medium effect size (d=0.37), indicating modest improvement in long-term glucose control.

Why this might work

Berberine triggers a cellular energy sensor called AMPK, which tells the liver to stop making excess sugar and tells muscles to take up more sugar from the blood, lowering long-term blood sugar levels.

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

    In people with schizophrenia and metabolic syndrome, taking 600 mg of berberine daily for 12 weeks slightly lowered their blood sugar marker (HbA1c) compared to those who took a placebo — like a small but real improvement in long-term blood sugar control.
