Good Manufacturing Practice establishes what kind of system for dietary supplements?

• A. System of quality assurance
• B. Advertising guidelines
• C. Packaging color standards
• D. Shelf-life testing

Answer: (A)

Good Manufacturing Practice establishes a system of quality assurance for dietary supplements. This means creating an integrated framework that covers every step of production—from facilities and equipment to trained personnel, written procedures, process controls, and meticulous record-keeping—to ensure products meet defined quality and safety standards. The aim is consistent quality, traceability, and prevention of contamination or errors throughout manufacturing and distribution. Advertising guidelines relate to marketing claims, packaging color is branding, and shelf-life testing is a specific quality check—useful, but not the overarching system that GMP defines.
