Marine Collagen Peptides Quality Management
Our Process
- From Cod Skin to Powder – Three Steps
-
Step 1 – Raw material acceptance
Frozen cod skins arrive with supplier certificates. We inspect for species, freshness, and contaminants. -
Step 2 – Enzymatic hydrolysis
Skins go into stainless steel reactors with water and food‑grade proteases. Temperature, pH, and time are controlled to reach 3300 Da average molecular weight. -
Step 3 – Purification, drying, sieving
The hydrolysate is filtered, concentrated, spray‑dried, and passed through a 60‑mesh sieve. Powder is packed into food‑grade bags/drums, labeled with batch number, and quarantined until QC passes all tests.

Understanding Marine Collagen Peptides
Collagen peptides is a general term for hydrolyzed collagen from any source (bovine, porcine, poultry). Marine collagen peptides specifically come from fish. Atnutra’s product is the latter – fish‑derived, Type I rich, and with an average molecular weight of 2800 Da.
Marine collagen peptides vs collagen peptides from bovine sources: marine typically has smaller peptide size (higher bioavailability) and is naturally BSE/TSE‑free. It is also suitable for pescatarian diets. Many formulators consider best marine collagen to be fish‑derived for beauty applications.
Approximately 3300 Da (batch 20250324). We test every batch and report the value on the COA.
≥92% on dry basis. Our last batch was 92.3%.
Yes. Every batch has its own COA with real test results – protein, hydroxyproline, molecular weight, heavy metals, microbiology.
Marine collagen price depends on volume, packaging, and delivery terms. For a current marine collagen powder price, contact us with your estimated monthly quantity. Typical bulk marine collagen pricing is competitive for premium quality.
Yes. We send up to 100g free sample for qualified companies. Shipping cost is on you, but we deduct it from your first bulk order.
36 months from manufacture date (expiry 2028.03.23 for batch 20250324), stored in original sealed packaging under 25°C, <65% humidity.
Yes. We are a marine collagen peptides manufacturer that provides marine collagen private label – stick packs, jars, capsules, tablets.
We are marine collagen manufacturer. We own the production facility and control the entire process.
The importance of marine collagen lies in its high bioavailability, sustainable sourcing (using fish by‑products), Type I dominance, and compatibility with pescatarian/clean‑label trends. It is widely considered one of the best marine collagen peptides sources for beauty and joint supplements.
