The Claim

In adults with schizophrenia and metabolic syndrome taking antipsychotics, adjunctive berberine at 600 mg/day for 12 weeks reduces net weight gain by 1.08 kg compared to placebo, with a medium effect size (d=0.59), indicating a clinically relevant attenuation of antipsychotic-induced weight gain.

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.

Cause and effect
1 study reviewed
In plain English

In adults with schizophrenia and metabolic syndrome who are taking antipsychotic medications, taking berberine at 600 mg per day for 12 weeks results in 1.08 kg less weight gain than taking a placebo, with a moderate effect size.

See the scientific wording

In adults with schizophrenia and metabolic syndrome taking antipsychotics, adjunctive berberine (600 mg/day for 12 weeks) reduces net weight gain by 1.08 kg compared to placebo, with a medium effect size (d=0.59), indicating a clinically relevant attenuation of antipsychotic-induced weight gain.

Why this might work

Berberine triggers a cellular energy sensor called AMPK, which turns off fat-making processes in the liver and fat cells, while turning on glucose uptake in muscles. This reduces fat storage and lowers blood sugar, leading to less weight gain.

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

    For people with schizophrenia who gain weight from their medication, taking 600 mg of berberine daily for 12 weeks helped them gain about 1 kg less than those taking a placebo, without making their psychosis worse.
