I/III
Type I & III Positioning vs. Measured Type Ratio
The certificate heading identifies this product as “Bovine Collagen Type I & III (Grass-Fed)” and lists bovine skin as the origin. However, the analytical table does not quantify the percentage ratio of Type I to Type III collagen. This page therefore does not publish a measured Type I:III ratio. Request current identity or source documentation if a quantified collagen-type composition is required for your market or formulation.
Product Overview
Grass-Fed Bovine-Skin Collagen Powder
The analytical certificate identifies bovine skin as the origin and the certificate title positions the ingredient as grass-fed Bovine Collagen Type I & III. The specification controls protein, nitrogen, molecular weight, hydroxyproline, ash, loss on drying, heavy metals, microbiology, mesh size and bulk density.
For ingredient qualification, use the current batch COA together with source, BSE/TSE, grass-fed, allergen and process documentation required by your quality and regulatory teams.

Supplier Qualification
What Matters When Sourcing Bovine Collagen Peptides
Current SERP leaders emphasize source identity, grass-fed documentation, COA, molecular weight, samples, packaging and traceability rather than generic benefit claims.
01
Source & Grass-Fed Documentation
The certificate heading states Grass-Fed and the origin is Bovine Skin. Request current source and grass-fed declarations for commercial qualification.
02
Protein & Peptide Control
The specification sets protein at ≥90%, hydroxyproline at ≥3.0% dry basis and molecular weight at ≤10,000.
03
Safety & Batch Testing
The analytical certificate includes heavy-metal and microbiological limits alongside mesh size, density and physical controls.
Formulation Pathways
Bovine Collagen for Supplement & Functional Food Development
Evaluate solubility, sensory properties, serving size and finished-product stability in your actual formulation before commercial scale-up.
01 / Beauty
Beauty-From-Within
Use bovine-source and protein documentation when developing collagen-focused beauty nutrition concepts.
02 / Powder
Collagen Drink Powders
Evaluate dispersibility, flavor system, powder flow and stability in sachet or tub formats.
03 / Solid Dose
Capsules & Tablets
Review serving size, bulk density, excipient compatibility and target dose during formulation.
04 / Food
Functional Food Concepts
Confirm sensory, processing and market-specific regulatory suitability in the intended food system.
B2B Sourcing
What to Request from a Bovine Collagen Supplier
For bulk bovine collagen qualification, current documentation matters more than broad “premium” or “high absorption” claims.
Current Batch COA
Confirm protein, physical properties, heavy metals and microbiology on the lot being purchased.
Grass-Fed & Source Declaration
Request current documentation supporting grass-fed status, bovine skin origin and traceability.
BSE / TSE Statement
Bovine-derived materials commonly require source-specific BSE/TSE qualification for certain buyers and markets.
Process / Hydrolysis Documentation
The COA lists a molecular-weight limit but does not explicitly describe the manufacturing or hydrolysis process.
Packaging, Sample & Commercial Terms
The certificate documents 20 kg net per bag; confirm current MOQ, availability, lead time and freight separately.
Buyer FAQ
Bovine Collagen Type I & III Sourcing Questions
What is the source of this bovine collagen?
The analytical certificate identifies the origin as bovine skin, and the certificate heading states Grass-Fed.
What is the protein specification?
The product specification is ≥90% protein. Batch 20260716 reports 93.8% protein.
What is the molecular weight specification?
The certificate specifies molecular weight at ≤10,000 and records the batch as passing. It does not publish a narrower numeric result.
Does the COA prove an exact Type I to Type III ratio?
No. The certificate heading identifies Bovine Collagen Type I & III, but the analytical table does not quantify a Type I:III ratio.
Is this hydrolyzed bovine collagen?
The certificate includes a molecular-weight specification but does not explicitly state the hydrolysis process. Request the current TDS or manufacturing-process documentation if hydrolysis status is required.
What packaging is documented?
The certificate lists 20 kg net weight per bag and 20.5 kg gross weight per bag.
What batch quality controls are included?
The analytical certificate includes protein, nitrogen, molecular weight, hydroxyproline, moisture/ash controls, lead, arsenic, cadmium, mercury, chromium and microbiological testing.
Can I request a current COA, BSE/TSE documents and a sample?
Yes. Contact ATNUTRA with your target application, market and expected volume to request the current technical package, sample availability and quotation.
