| Collagen Source | Common sources include bovine, porcine, marine, and poultry materials. Source selection affects allergen, religious, dietary, sustainability, and traceability requirements. | Species, tissue type, country of origin, slaughter or harvest controls, and whether the source is wild-caught, farmed, or land-based. | Raw-material specification, origin declaration, supplier questionnaire, traceability records, and applicable certificates for halal, kosher, or other dietary requirements. |
| Collagen Type | Type I is associated mainly with skin, bone, tendon, and connective tissue. Type II is primarily associated with cartilage. Type III is commonly found with Type I in connective tissues. | Declared collagen type, analytical basis for the declaration, and whether the product contains native collagen or hydrolyzed collagen peptides. | Technical data sheet, identity testing, manufacturing process description, and certificate of analysis for each lot. |
| Hydrolysis and Molecular Profile | Hydrolyzed collagen is produced by breaking collagen proteins into smaller peptides. A claimed average molecular-weight range is a quality attribute, not a universal legal standard. | Hydrolysis method, degree of hydrolysis, solubility, dispersibility, peptide-size distribution, and batch-to-batch consistency. | Validated analytical method, molecular-weight or peptide-profile report, stability data, and agreed product specification. |
| Identity and Authenticity | The finished material should be demonstrably collagen or collagen peptides and should not be economically adulterated with undeclared proteins or nitrogen-containing substances. | Identity method, protein or peptide content, amino-acid profile, adulteration controls, and species authentication where relevant. | Lot-specific certificate of analysis, validated identity testing, supplier audit results, and independent confirmation for high-risk materials. |
| Protein and Purity Specification | Protein content, moisture, ash, pH, solubility, and sensory characteristics should be controlled against a written specification. There is no single global legal purity percentage for all collagen products. | Acceptance limits, test methods, sampling plan, re-test period, and handling of out-of-specification results. | Approved specification, current certificate of analysis, method validation or verification, and quality agreement. |
| Microbiological Safety | Microbiological criteria depend on product form, intended use, jurisdiction, and whether the product is ready to consume. Pathogens and indicator organisms must be controlled. | Total aerobic count, yeast and mold, relevant pathogens, sampling frequency, environmental monitoring, and validated kill or control steps. | Lot-specific microbiology results, environmental-monitoring records, sanitation procedures, and corrective-action history. |
| Heavy Metals and Environmental Contaminants | Lead, cadmium, mercury, arsenic, and other contaminants may be relevant. Marine materials may require additional assessment for contaminants associated with the harvest environment. | Total and, where applicable, inorganic arsenic; analytical limits of quantification; sampling plan; and compliance with the destination-market limits. | Accredited-laboratory reports, risk-based contaminant monitoring plan, and documented comparison with applicable legal limits. |
| Allergen and Cross-Contact Control | Marine collagen may be subject to fish or shellfish allergen rules depending on the source and destination market. Shared equipment can create cross-contact risks. | Allergen profile, facility allergen map, cleaning validation, dedicated-line controls, and labeling information. | Allergen statement, cross-contact assessment, cleaning records, and destination-market label review. |
| Animal Health and BSE/TSE Controls | For ruminant-derived collagen, controls concerning specified risk materials, animal origin, processing, and transmissible spongiform encephalopathy may be relevant to import eligibility. | Species and tissue eligibility, veterinary controls, origin restrictions, heat or processing controls, and import documentation. | Veterinary or sanitary certificates where required, raw-material declarations, and documented import compliance review. |
| Manufacturing Controls | In the United States, dietary supplement manufacturers are subject to current good manufacturing practice requirements under 21 CFR Part 111. Other markets apply their own food or supplement hygiene rules. | Process validation, sanitation, personnel training, calibration, deviation management, complaints, recalls, and change control. | Recent third-party audit, internal audit summary, batch records, corrective-action records, and quality agreement. |
| Food-Contact and Processing Aids | Processing aids, carriers, anti-caking agents, flavors, and packaging materials must be permitted for the intended use in the destination market. | Complete formulation, processing-aid list, residual limits, packaging compatibility, and migration or safety documentation where applicable. | Full ingredient disclosure, supplier declarations, specifications, and regulatory assessment for each market. |
| Stability and Shelf Life | Shelf life should be supported by real-time or appropriately justified accelerated stability data under stated storage conditions. | Temperature and humidity conditions, packaging configuration, critical quality attributes, and post-opening storage requirements. | Stability protocol, time-point results, packaging study, and expiration-date justification. |
| Claims and Scientific Substantiation | Claims about skin, joints, bones, or other health outcomes must comply with the rules of the target market. Evidence should support the exact ingredient, dose, population, and claimed benefit. | Claim wording, serving size, study relevance, adverse-event information, and whether the claim could be considered a disease or medicinal claim. | Claim substantiation dossier, literature review, human-study records where used, and legal or regulatory label review. |
| United States Regulatory File | A finished dietary supplement must meet applicable U.S. labeling, manufacturing, safety, and recordkeeping requirements. New dietary ingredient notification may be relevant when an ingredient meets the applicable statutory conditions. | Product classification, ingredient history, label compliance, serious adverse-event process, and facility registration obligations where applicable. | Regulatory assessment, label review, safety dossier, 21 CFR Part 111 documentation, and required submissions or notifications. |
| European Union Market Access | EU requirements can involve food-supplement legislation, general food law, hygiene rules, health-claim rules, labeling rules, and potentially novel-food assessment. Requirements may differ by Member State. | Novel-food status, permitted ingredients and additives, nutrition information, health claims, maximum levels where established nationally, and notification requirements. | EU and Member-State regulatory review, label dossier, ingredient-status assessment, and documented claim authorization basis. |
| Traceability and Recall Readiness | The business should be able to trace each lot through raw materials, processing, packaging, distribution, and customers, and should maintain an effective withdrawal or recall procedure. | Lot coding, one-step-back and one-step-forward records, retention samples, complaint handling, and mock-recall performance. | Traceability map, mock-recall report, retention-sample policy, and documented recall communication process. |
| Supplier Qualification | Supplier approval should be risk-based and completed before commercial purchase. Price alone is not sufficient evidence of suitability. | Quality history, capacity, subcontractors, regulatory inspections, audit findings, business continuity, and change-notification practices. | Completed supplier qualification file, audit report, quality agreement, insurance documentation, and approved-vendor status. |
| Sustainability and Ethical Sourcing | Collagen is often produced from animal by-products, which can support resource efficiency, but environmental impact depends on source, processing, energy, water, transport, and waste management. | By-product origin, fisheries or farm controls, water and energy use, wastewater management, labor practices, and sustainability claims. | Documented sustainability methodology, chain-of-custody records, environmental data, and substantiation for any on-pack environmental claim. |
