- Label design
- Packaging procurement
Correct Answer: CAPA (Corrective and Preventive Action)
Q7. When qualifying a raw material supplier for nutraceuticals, the most critical initial step is to:

- Conduct a supplier audit or obtain a comprehensive quality agreement and certificates of analysis
- Require overnight shipping
- Obtain promotional literature
Correct Answer: Conduct a supplier audit or obtain a comprehensive quality agreement and certificates of analysis
Q8. Which environmental control parameter is most critical to control in a production area handling hygroscopic powders and why?
- Humidity, because it affects powder flow, stability and microbial growth
- Noise, because it affects operator concentration
- Light intensity, because it affects packaging readability
- Vibration, because it improves mixing
Correct Answer: Humidity, because it affects powder flow, stability and microbial growth
Q9. A nutraceutical manufacturer must perform identity testing of a botanical ingredient. Which analytical approach best ensures botanical identity and absence of adulteration?
- Visual inspection alone
- DNA barcoding combined with chromatographic fingerprinting
- Using vendor-provided images
- Relying solely on supplier COA without verification
Correct Answer: DNA barcoding combined with chromatographic fingerprinting
Q10. Under GMP for nutraceuticals, which practice is essential to ensure product traceability?
- Random sampling without documentation
- Unique batch numbers and maintained batch records linking raw materials through finished goods
- Mixing multiple batches to save storage space
- Destroying all incoming documentation after blending
Correct Answer: Unique batch numbers and maintained batch records linking raw materials through finished goods
Q11. Which limit should be included in specifications for finished nutraceutical products to control safety risks?
- Maximum potency above label claim
- Acceptable heavy metals limits (e.g., lead, arsenic, cadmium, mercury)
- Minimum packaging thickness
- Supplier marketing claims
Correct Answer: Acceptable heavy metals limits (e.g., lead, arsenic, cadmium, mercury)
Q12. For stability testing of a nutraceutical softgel intended for tropical markets, which condition is most appropriate to include?
- Long-term at 25°C/60% RH only
- Accelerated at 40°C/75% RH and an intermediate condition if required
- Freezer conditions only
- Testing at 10°C/10% RH only
Correct Answer: Accelerated at 40°C/75% RH and an intermediate condition if required
Q13. In-process controls (IPCs) during tablet compression of a nutraceutical formulation typically include monitoring:
- Marketing plan
- Weight variation, hardness, and disintegration time
- Employee attendance
- Number of promotional samples produced
Correct Answer: Weight variation, hardness, and disintegration time
Q14. Which contamination control practice specifically addresses allergen risk in a shared facility?
- Ignoring allergen labeling requirements
- Dedicated equipment or validated cleaning procedures and scheduling production to prevent allergen carryover
- Using the same line for all products without segregation
- Reducing raw material testing
Correct Answer: Dedicated equipment or validated cleaning procedures and scheduling production to prevent allergen carryover
Q15. Microbiological specifications for non-sterile nutraceutical powders should include controls for which of the following?
- Total aerobic microbial count, yeast and mold counts, and absence of pathogenic organisms like Salmonella and E. coli
- Only odor assessment
- Only moisture content
- Only visual color assessment
Correct Answer: Total aerobic microbial count, yeast and mold counts, and absence of pathogenic organisms like Salmonella and E. coli
Q16. Which program is crucial to manage changes in formulation, process, or equipment while maintaining product quality?
- Promotional campaign planning
- Change control system with assessment, approval, and documentation
