The quality of the Berberine caps has been bad since they launched new packaging. It smells gross. 2 things are in the caps, normal yellow Berberine powder & unknown brown granulated substances. Since I bought 2 bottles via Ebay, their AI assistant rejects my complaints. So I bought one more from their website, the results are the same, not to say it’s less effective. Vital Nutrients claims their products are of purity, potency and the absence of contaminants. It’s a lie. Time to switch brands.
