What berberine is
Berberine is a plant compound found in several botanicals and has been studied for metabolic outcomes, including glucose and lipid measures.
What the evidence says
NCCIH notes that some studies suggest berberine may reduce weight or BMI, but the evidence is not conclusive. Study quality, populations and formulations vary.
Safety and interactions
NCCIH warns that berberine can interact with medicines and should not be used during pregnancy or breastfeeding. That makes it especially important to know whether a multi-ingredient formula actually contains berberine and at what dose.
Relevance to Gelatine Sculpt
One current Gelatine Sculpt portal lists berberine; some other label reports do not. Verify the bottle instead of assuming the marketing page you found matches the product you will receive.
