What Makes Keratin Peptide Different?
Keratin is a structural fibrous protein naturally abundant in feathers, hair, hooves, and wool. Through controlled enzymatic hydrolysis, we break the intact keratin molecule into short-chain peptides — delivering a highly concentrated, rapidly absorbed protein ingredient that intact keratin simply cannot match.
The resulting powder contains the full keratin amino acid profile — notably rich in cystine, glycine, and proline — in a form that your formulation team can actually work with: fine 60-mesh powder, clean taste, low ash, and tight moisture control.
Non-mammalian sourcing opens doors for brands targeting vegan-adjacent, non-bovine, or halal-aligned positioning — without sacrificing amino acid depth.

Manufactured with Uncompromising Quality
Partner with a true source factory. Gensei Global Industries operates strictly under international manufacturing standards.
Inside Our Facility
Extraction & Spray Drying Towers
High-capacity vessels designed for industrial-scale pure peptide output.
In-House QA Laboratory
Equipped with precise testing instruments for heavy metals and microbiological screening.
Strict 3-Step Quality Control
Incoming Raw Material Audit
Strict veterinary inspection and heavy metal screening for every batch of raw beef stock.
In-Process Testing
Real-time monitoring of pH, molecular weight, and protein concentration during extraction.
Final COA Verification
Final panel testing for Melamine, Pathogens, and Amino Acid Profile before dispatch.
Applications Across Industries
Beef protein isolate is a versatile, high-purity ingredient suited for demanding formulation environments across multiple industry segments.
Hair, Skin & Nail Supplements
Keratin's native role is structural — it forms the building blocks of hair cortex, nail plate, and skin barrier. Hydrolyzed keratin peptides in supplement form provide targeted amino acid delivery to support these tissues from within, a strong label claim for beauty-from-within brands.
Sports & Recovery Nutrition
The cystine content and structural amino acid profile complement conventional sports protein stacks. Keratin peptides are being explored as a tissue-repair adjunct in sports nutrition, particularly in joint and connective tissue formulas targeting active consumers.
Private Label & Contract Manufacturing
Contract manufacturers gain a differentiating, COA-backed ingredient that can anchor new SKUs in an increasingly crowded supplement market. Keratin peptide adds scientific depth to private label beauty and wellness formulations without complexity in production.
Veterinary & Pet Nutrition
Avian-derived keratin peptide is a natural fit for pet coat, skin, and joint support formulations. The feather origin aligns with common pet food ingredient norms, and the low microbial load (300 CFU/g total bacteria) meets premium pet supplement quality expectations.
What You Actually Need
Beyond the spec sheet — the operational reasons procurement teams come back to us.
US Warehouse — No Import Friction
Domestic stock means no customs clearance delays, no ocean freight exposure, and no import documentation overhead. Orders ship in 48–72 hours from confirmed payment, with full tracking from our US fulfillment point.
Documentation Ready Before You Order
COA, MSDS, allergen declaration, and spec sheet are available on request — before any purchase commitment. Your regulatory and QC teams can review everything upfront, compressing your onboarding cycle.
Consistent Batch Quality
Our GMP facility in Hefei runs dedicated production lines for hydrolyzed protein ingredients. Every batch is tested against the same specification set — you're not buying spot-market variability, you're buying a repeatable ingredient standard.
Flexible Volume for Growing Brands
We don't force large MOQs on brands that are still scaling. Whether you're validating a new SKU or running your third production cycle, we structure orders around your actual purchasing cadence, not ours.
From Inquiry to Delivered Ingredient
We’ve streamlined the B2B procurement process so you spend less time chasing paperwork and more time building your product.
Frequently Asked Questions
The questions we get most from R&D, procurement, and quality assurance contacts before a first order.
What is the raw material source, and does it raise any regulatory concerns?
The raw material is poultry feathers (avian-derived). This is significant for regulatory purposes: feather keratin carries no BSE/TSE risk associated with bovine or ovine materials, simplifying filings in markets with strict ruminant ingredient controls. It also supports clean supply chain narratives for brands with traceability requirements.
How does the molecular weight of <2,000 Da affect formulation decisions?
Low molecular weight peptides (<2,000 Da) are generally absorbed through intestinal epithelium more efficiently than intact proteins or large polypeptides. For supplement brands, this supports bioavailability positioning on label — particularly relevant in beauty-from-within and sports recovery categories where consumers are increasingly sophisticated about ingredient science.
What certifications and documents are available?
Standard documentation includes the batch COA, MSDS / Safety Data Sheet, Allergen Declaration, Specification Sheet, and Country of Origin certificate. The production facility operates under GMP standards. Halal and Kosher documentation can be discussed — please specify your needs in the inquiry form.
Is it suitable for use in capsule, powder sachet, or gummy formats?
The 60-mesh powder format is well-suited for capsule filling and powder sachet production. For gummy or chewable formats, the powder's neutral taste profile and pH of 6.3 are compatible, though we recommend your formulation team evaluate at bench scale with your specific gummy base and flavor system before committing to production quantities.
Can I combine keratin peptide with collagen peptide in a single product?
Keratin and collagen peptides are frequently used together in hair, skin, and nail formulations. They are structurally complementary — collagen supports dermal matrix and elasticity, while keratin provides the fibrous structural protein component of hair and nails. Gensei Global also supplies chicken bone broth collagen peptide if you're building a combined product; ask our team about combined sample requests.
What is the current batch quantity and shelf life?
Current batch (20250810) quantity is 18,500 kg, packaged in 20 kg bags. Manufactured August 10, 2025, with an expiry date of August 9, 2028 — a 3-year shelf life from production. Contact us for current availability and lead times if you're planning a large volume purchase.
