Client Context
The client was establishing a new manufacturing operation in Canada for their portfolio of dietary supplements. As part of this expansion, they needed to transfer 12 supplement Stock Keeping Units from their international production sites to the new Canadian facility.
In Canada, dietary supplements are regulated by Health Canada as Natural Health Products, which require product-specific registration and approval before they can be sold. Each approved product receives a Natural Health Product Number that must appear on the product label, signifying compliance with Canadian regulatory standards.
The client needed expert guidance to navigate Health Canada’s stringent quality requirements, develop compliant Finished Product Specifications, and establish the stability data foundation necessary to assign defensible expiration dates to their products.
The challenge
Regulatory Complexity
Health Canada requires Finished Product Specifications to be developed in accordance with specific quality guidelines for Natural Health Products, which differ significantly from pharmaceutical or food regulations.
Ingredient Diversity
Unlike pharmaceuticals with well-defined chemical entities, dietary supplements contain chemically complex constituents including botanicals, animal-derived materials, probiotics, and refined ingredients—each presenting unique analytical challenges.
Cost Optimization
Quality control testing can be expensive, particularly for stability studies that repeat tests over extended timeframes. Identifying where testing can be scientifically justified for reduction is critical to operational efficiency.
Technical Sequencing
Finished Product Specifications must be finalized before initiating stability studies, as these studies repeat specification tests over time. Poor specification design can result in costly study failures or regulatory rejections.
Data Requirements
Health Canada mandates stability studies to justify expiration dating. These studies must be designed with appropriate test parameters, storage conditions, and sampling intervals to meet regulatory expectations.
Laboratory Partnerships
Identifying qualified analytical laboratories capable of performing specialized Natural Health Product testing across diverse matrices requires industry knowledge and established networks.
What We Did
Terraforme Biosciences provided end-to-end support for the development of compliant Finished Product Specifications and the design and execution of stability studies across the client’s 12-product portfolio.
Finished Product Specification Development
We conducted a comprehensive analysis of each product’s formulation, ingredient complexity, and manufacturing process to develop scientifically robust and regulatorily compliant Finished Product Specifications. This included defining the specific tests required for batch release and establishing acceptance criteria based on product characteristics, regulatory requirements, and quality risk assessment.
Risk-Based Testing Strategy
We worked closely with the client to identify opportunities to streamline testing requirements without compromising product quality or regulatory compliance. By reviewing raw material Certificates of Analysis and evaluating manufacturing process controls, we developed rationales to eliminate redundant testing on finished products. This approach reduced the financial burden of routine batch release testing while maintaining robust quality assurance.
Stability Study Design
We designed comprehensive stability protocols for each product that would generate the data required to support expiration date assignments. This included determining appropriate storage conditions, establishing testing timepoints, and selecting which specification tests needed to be repeated during stability monitoring. Through careful risk assessment, we identified tests from the Finished Product Specifications that could be justifiably excluded from stability protocols, reducing study costs without compromising regulatory defensibility.
Laboratory Procurement Support
Leveraging our extensive network of analytical testing laboratories, we prepared detailed Requests for Quotation for both routine quality control testing and stability studies. We evaluated laboratory capabilities, turnaround times, and pricing to help the client select partners that met their technical and budgetary requirements.
Ongoing Stability Management
We provided continuous support throughout the stability study lifecycle, including protocol finalization, review of ongoing stability pull data, troubleshooting of out-of-specification results, and generation of final stability reports suitable for submission to Health Canada as part of Natural Health Product Number applications.
The Approach
Our methodology integrated regulatory expertise with practical manufacturing knowledge and analytical chemistry understanding to deliver specifications and studies that were both compliant and operationally efficient.
Ingredient-Specific Risk Assessment
We recognized that each ingredient class—botanicals, probiotics, animal derivatives, and refined materials—presents distinct stability and analytical challenges. Our specification development was tailored to the unique risk profile of each product’s formulation rather than applying a generic template.
Regulatory Alignment
All specifications and stability protocols were developed in strict accordance with Health Canada’s Quality Guide for Natural Health Products, ensuring that the documentation would withstand regulatory scrutiny during Natural Health Product Number review.
Cost-Conscious Quality
We balanced regulatory compliance with financial pragmatism by identifying where upstream controls—such as raw material testing or in-process monitoring—could reduce the need for redundant finished product testing. This required deep understanding of both the regulatory framework and the client’s manufacturing capabilities.
Laboratory Network Leverage
Our established relationships with specialized analytical laboratories enabled us to quickly identify testing partners with the specific capabilities required for complex Natural Health Product matrices, accelerating procurement timelines and ensuring quality results.
Deliverables
1) Finished Product Specifications
Twelve formally controlled specification documents defining batch release testing requirements and acceptance criteria for each Stock Keeping Unit, compliant with Health Canada Natural Health Product quality guidelines.
2) Stability Study Protocols
Comprehensive stability testing protocols for each product, including storage conditions, sampling timepoints, test parameters, and acceptance criteria designed to support expiration date assignments.
3) Testing Reduction Rationales
Scientific justifications documenting where and why certain tests could be eliminated from routine batch release or stability monitoring based on raw material controls, process understanding, and risk assessment.
4) Laboratory Request for Quotation Packages
Detailed procurement documents for analytical testing services, including test method requirements, sample volumes, reporting timelines, and evaluation criteria for laboratory selection.
5) Stability Data Review Reports
Ongoing assessments of stability pull data with trend analysis, out-of-specification investigations, and recommendations for protocol modifications if needed.
6) Final Stability Reports
Comprehensive stability study reports summarizing all data, establishing expiration dates, and providing regulatory-ready documentation for Natural Health Product Number submissions to Health Canada.
Lessons Learned
Specifications Drive Stability Success
Poorly designed Finished Product Specifications create cascading problems in stability studies. Investing time upfront to develop robust, risk-based specifications prevents costly study failures and regulatory delays.
Ingredient Complexity Demands Expertise
Natural Health Products span an enormous range of chemical complexity. Generic approaches to specification development fail to account for the unique stability and analytical challenges of botanicals, probiotics, and other complex matrices. Specialized knowledge is essential.
Strategic Testing Reduction Requires Defensibility
Reducing testing burden to control costs is desirable, but only when supported by sound scientific rationale. Regulators accept testing reductions when backed by raw material data, process controls, and risk assessment—but not when based solely on cost considerations.
Laboratory Capabilities Vary Widely
Not all analytical laboratories have the specialized equipment, method expertise, or experience required for Natural Health Product testing. Early engagement with qualified partners prevents project delays and data quality issues.
