The best raw materials are the ones you never have to second-guess. Fish collagen peptides from Eata Marisource are built for exactly that kind of confidence: marine-sourced Type I collagen, gently broken down through controlled enzymatic hydrolysis into short peptide chains that dissolve fast, stay neutral in taste, and behave predictably from the first lab batch to full-scale production.
Eata Marisource is a dedicated supplier of marine-derived raw materials, and fish collagen peptides sit at the heart of our range. We start with fresh skin and scale by-products of the fishing industry — collagen-rich material that would otherwise go to waste — and transform it through a clean, traceable process into a high-protein functional ingredient. What reaches your facility is a fine white powder with documented composition, consistent lot-to-lot performance, and a sourcing story your customers can actually feel good about.
Product Range at a Glance
Depending on your market, this same ingredient travels under several names — hydrolyzed fish collagen, marine collagen peptides, collagen tripeptide, fish scale collagen — and we supply all of them from the same quality-controlled line. The overview below outlines the grades we most often supply; tell us your target specification and we will match or tune it.

What Sets These Peptides Apart
- Small molecules, fast absorption. Our standard grades hold average molecular weights in the 500–3000 Da range, with tighter fractions available on request. Short chains are easier to absorb and kinder to your formulation — a real advantage when your product’s promise depends on it.
- A neutral profile that stays out of the way. Dedicated decolorization and deodorization steps remove the fishy character. What you get is a light, near-odorless powder that won’t fight your flavor system, your fragrance, or your clean-label story.
- Batch-to-batch consistency you can plan around. Hydrolysis conditions are controlled tightly enough that molecular-weight distribution, viscosity and solubility stay stable across lots. R&D findings carry over to production instead of being rediscovered the hard way.
- Sourced with a sustainability angle. Because our supply chain is built on fishing-industry by-products, choosing these peptides is also a choice to use the ocean’s resources more fully — a point that resonates with increasingly conscious end customers.

Amino Acid Profile
Collagen is defined by its amino acid fingerprint, and ours is rich in the building blocks that matter most — glycine, proline and hydroxyproline — alongside a full complement of 18 amino acids, including all essential ones.

Built for the Products Your Customers Reach For
Cosmetics and personal care
Skincare serums, masks, anti-aging creams and hair-and-nail care all draw on Type I collagen peptides for hydration, elasticity and barrier-support benefits. The same ingredient moves easily into the beauty-from-within segment, where oral formats take it beyond the jar.
Functional food and beverage
Collagen shots, protein drinks, gummies, bars and dessert mixes all benefit from a peptide that dissolves in cold water and leaves no taste behind. A clear, stable solution keeps clean-label claims honest from bench to bottle.
Sports and wellness nutrition
Peptide-rich blends for muscle recovery and joint-comfort products turn a familiar protein story into something more differentiated — and give formulators a marine point of difference over conventional sources.
Biomedical and material research
For teams working on scaffolds, films, coatings and other collagen-based materials, the value is in the documentation: consistent composition, a known molecular-weight range and a full amino acid profile, batch after batch.
Quality You Can Verify, Not Just Trust
- Documentation on every lot. Each batch ships with a Certificate of Analysis covering protein content, molecular weight, amino acids, heavy metals and microbiology.
- Traceability from catch to powder. Raw materials can be traced back to their source, so you have an answer for every question your own auditors might ask.
- Recognized management frameworks. Production follows ISO 9001, ISO 22000 and HACCP principles, with Halal and Kosher certification available on request.
- Documents for your market access. From third-party test reports to certificates of origin, the paperwork your compliance team needs can be arranged through us.

Packaging, Samples and Documentation
Standard packaging is designed for one thing: keeping the powder dry and stable. Options include 1 kg foil-lined bags, 10 kg and 20 kg cartons with PE inner liners, and fiber drums for larger volumes — with custom packing configurations available to match your warehouse and filling lines.
Samples for evaluation ship quickly, and each order is supported by the usual commercial documents: COA, MSDS, origin certificate and, where applicable, third-party test reports. If you are evaluating a new supplier, that is usually all you need to move forward.

Standard grades only take you so far, and we understand that. Our team is set up for customization: molecular weight, particle size, solubility behavior, packaging and documentation can all be adjusted to your target specification. Tell us what your application demands — we will develop samples with you and carry the chosen profile through to full production.
