Introduction: Stability, safety assessment and regulatory dossiers for nutraceuticals MCQs With Answer provides M.Pharm students with focused practice on critical regulatory concepts. This blog covers stability testing principles, standard safety assessment batteries, and the structure and content of regulatory dossiers required for nutraceuticals worldwide. Questions emphasize ICH stability protocols, packaging influences, toxicology endpoints (acute, subchronic, chronic, genotoxicity, reproductive toxicity), ADME considerations, and region-specific dossier expectations including DSHEA, EFSA, FSSAI and global best practices like eCTD/Module approaches. The MCQs are designed to deepen understanding for exam preparation and real-world regulatory submission planning, helping students integrate quality, safety and regulatory strategy for nutraceutical products.

- It may be classified as a cosmetic
- It may trigger classification as a pharmaceutical/drug requiring full drug approval
- It will be exempt from labeling requirements
- It can be marketed without documentation of safety
Correct Answer: It may trigger classification as a pharmaceutical/drug requiring full drug approval
Q10. Which study provides the most direct information on absorption, distribution, metabolism and excretion (ADME) of a nutraceutical compound?

- No information is required; notification is optional
Correct Answer: Safety documentation including history of use or toxicological data submitted to FDA at least 75 days prior to marketing
Q12. Which is the best approach to assess potential herb–drug interactions for a multi-constituent nutraceutical?
- Assume interactions are negligible if doses are low

- Marketing authorization from a member state suffices for all EU countries
- No dossier if used historically in non-EU countries
Correct Answer: Comprehensive dossier with characterization, toxicology, and history of use or safety data
