Type Iii Collagen Peptide
Type III Collagen Peptide is a hydrolysed collagen ingredient enriched in fragments derived from the type III collagen fraction of animal connective tissue, marketed primarily for skin, vascular, and soft-tissue support.
Type III collagen co-distributes with type I in skin, blood vessels, and the walls of hollow organs, where it forms thinner reticular fibrils that contribute to tissue elasticity. Peptides positioned as type III enriched are typically produced from bovine hide or fish skin, where the type I to type III ratio in the starting material favors a higher type III recovery than in tendon-derived feedstocks.
We source bulk Type Iii Collagen Peptide from top China manufacturers for our partners. The manufacturer is in Beijing. A smaller requirement can ship in a combined container with other ingredients.
Please send the grade you need, the volume and your destination port, and we will come back with a solution and a price.

Common Markets Grades
The standard grade is a free-flowing white to pale yellow powder with an average molecular weight in the 2,000 to 5,000 dalton range. This molecular-weight window is associated with high water solubility and good oral bioavailability of signaling di- and tripeptides.
Premium grades are characterised by the ratio of type III to type I collagen confirmed by SDS-PAGE banding or by quantitative mass spectrometry of marker peptide sequences. A common positioning is a type III enrichment of 10 to 30 percent of total collagen.
Cosmeceutical grades are made to lower endotoxin and tighter heavy-metal specifications for use in leave-on skin-care formulations.
Bovine-source and marine-source variants are both commercially available. Marine type III peptides tend to carry a cleaner sensory profile and are preferred for clear beverages.

How We Help Source Type Iii Collagen Peptide
Direct Factory Sourcing
We run the whole process: selecting the manufacturer from the top Chinese food ingredient producers, negotiating the price, verifying quality, and coordinating the logistics. You deal with us instead of with several factories at once.
Original Packaging and Documents from the Manufacturer
The manufacturer sends your Type Iii Collagen Peptide out of its own factory in the original packing, through to your destination port. The COA, COO, MSDS, TDS and any certifications reach you from the manufacturer as well.
Free Samples and Lead Time
We send 100 to 500 g free for your own laboratory to test and you cover only the courier, usually within 2 to 3 working days. ETD is usually within 7 to 15 days once the order is confirmed, and we check that date against the factory's own manufacturing schedule before we give it to you.
Combined Shipment
We can load Type Iii Collagen Peptide together with other ingredients such as Collagen Peptide, Soy Protein Isolate and Fish Collagen Peptide into one 20' FCL. If your quantity is small, we can also ship LCL.
Regulatory Status
Hydrolysed collagen is widely accepted as a food ingredient and a dietary supplement component. In the United States it falls under standard GRAS practice when produced from approved animal sources under sanitary conditions.
In the European Union, collagen peptides from bovine sources require compliance with TSE and BSE controls under the Specified Risk Material framework. Marine-source peptides require fish-allergen labelling.
Japan and South Korea both maintain active markets for type III enriched collagen peptides in beauty-from-within categories, with disclosure requirements governed by their respective health-food and cosmetic codes.
Halal and Kosher certifications exist for bovine-source material from accredited slaughterhouses, and for marine-source material processed in dedicated lines.
Manufacturing Process
The process begins with selection of feedstocks rich in type III collagen. Bovine hide split layers and fish skins generally carry a higher type III fraction than bone or tendon raw materials.
Hides are cleaned, dehaired, and limed to remove non-collagenous proteins and fats. The pretreated material is then washed to neutral pH.
Controlled enzymatic hydrolysis follows, using food-grade proteases selected to cleave at sites that release defined peptide fragments. Pepsin, alcalase, papain, and bromelain are all in use, often in staged combinations to hit a target molecular-weight distribution.
The hydrolysate is filtered, decolorised with activated carbon, concentrated by evaporation, and spray-dried. Final material is sieved and blended to homogenise molecular weight and ash content.
Identity of the type III enrichment is verified by gel electrophoresis or by tracking marker peptide sequences specific to the alpha-1(III) chain.
