Berberine hydrochloride is poorly absorbed and appears to act largely through intestinal and metabolic pathways. Cell and animal work supports mitochondrial complex-I inhibition, AMPK activation, LDL-receptor regulation and microbiome effects, but the clinical mechanism has not been established in humans.
Purpose, evidence and practical considerations.
Gastrointestinal effects, especially constipation, diarrhea, abdominal pain and nausea, are common. Berberine can affect CYP enzymes and P-glycoprotein and may add to glucose- or blood-pressure-lowering medicines. Avoid during pregnancy and breastfeeding and do not use it as a substitute for prescribed diabetes or lipid treatment.
