As a health-related consumable, the product must meet strict safety standards. You should verify that the manufacturer holds ISO 22000 or HACCP certifications for food safety management. For specific markets, ensure compliance with FDA regulations (USA), EFSA standards (EU), or GMP (Good Manufacturing Practice). Additionally, request third-party lab test reports confirming the absence of heavy metals (lead, mercury), pesticide residues, and illegal pharmaceutical additives like metformin or glibenclamide.
