Marine Collagen Peptides for Nutraceutical Formulations
Codfish-skin marine collagen powder for B2B ingredient sourcing. Review the reference batch COA, technical specifications and packaging before evaluating the ingredient for supplement and functional food projects.

Use the current product and batch documentation for supplier qualification, formulation review and label decisions.
Codfish-Skin Marine Collagen Powder
This marine collagen ingredient is documented in the supplied reference COA as collagen originating from codfish skin. The batch specification controls protein, molecular weight, hydroxyproline, ash, loss on drying, heavy metals, microbiology, mesh size and bulk density.
For B2B sourcing, the page is structured around the data formulation, procurement and quality teams need before commercial evaluation rather than unverified absorption or therapeutic claims.

Marine Collagen COA Specifications
Specification limits and reference-batch results below reproduce the supplied COA. “Pass” means the reference batch met the stated specification; it is not a numeric result.

What Buyers Can Verify from the COA
Use measurable specification controls—not broad marketing claims—to compare marine collagen suppliers during qualification.
Protein & Identity Markers
The specification sets protein at ≥90% and hydroxyproline on a dry basis at ≥3.0%, with the reference batch recording 92.21% protein.
Molecular Weight Control
The COA specification sets molecular weight at ≤10,000 Da. The reference batch is reported as passing this limit; the COA does not state a narrower numeric range.
Safety & Micro Testing
The reference COA includes lead, arsenic, cadmium, mercury, chromium and microbiological controls, with the reported batch conforming to the listed limits.
Marine Collagen Peptides for Product Development
These are common formulation pathways to evaluate during R&D. Finished-product suitability should be confirmed through your own formulation and stability testing.
Collagen Drink Powders
Evaluate dispersibility, flavor system, serving size and finished-powder stability before scale-up.
Beauty-From-Within
Use the source, protein specification and product documentation when developing marine-positioned beauty nutrition concepts.
Sachets & Capsules
Review bulk density, serving size, excipient compatibility and packaging requirements for the target dosage form.
Functional Food Concepts
Confirm processing compatibility, sensory performance and local regulatory suitability in the finished formulation.
What to Request Before Qualification
A marine collagen peptide supplier should be evaluated on current batch documentation, product identity and commercial terms—not only headline protein percentage.
Confirm the actual lot you intend to qualify rather than relying only on a historical reference batch.
Confirm product naming, source declaration, processing information, storage and current specification limits.
The reference COA identifies codfish skin as the source, so target-market allergen requirements should be reviewed.
Test sensory characteristics, dispersibility and compatibility in your actual finished-product system.
The reference COA records 20 kg net per bag. Request current commercial terms for MOQ, availability and delivery.

Marine Collagen Peptide Sourcing Questions
What is the source of this marine collagen?
The supplied reference COA identifies the origin as codfish skin.
What is the protein specification for the marine collagen powder?
The COA specification is ≥90% protein. Reference batch 20260324 reports a protein result of 92.21%.
What is the molecular weight specification?
The reference COA sets molecular weight at ≤10,000 Da and records the batch as passing. It does not provide a narrower numeric molecular-weight result.
Is this hydrolyzed marine collagen?
The supplied COA identifies the product as Marine Collagen and lists a molecular-weight specification, but it does not explicitly state the processing method. If hydrolysis status is required for formulation or labeling, request the current TDS or process documentation.
What packaging is documented in the COA?
The reference batch lists 20 kg net weight per bag and 20.5 kg gross weight per bag. Confirm current packaging when requesting a commercial quotation.
Does the COA include heavy-metal and microbiological testing?
Yes. The supplied COA includes lead, arsenic, cadmium, mercury, chromium, total bacteria, coliform, E. coli, mold and yeast, and Salmonella/Staph. aureus controls.
Should this ingredient be reviewed for fish allergen labeling?
Because the reference COA identifies codfish skin as the origin, the finished formulation should be reviewed against fish-allergen labeling requirements in the intended market.
Can I request a current COA and sample before ordering?
Use the contact form to request current batch documentation, sample availability and commercial terms for your project.
