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.
Formulation-Friendly. Industry-Leading Specs.
O nosso Isolado de proteína de carne de bovino is designed as a neutral, high-performance base for premium supplement brands.

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. Queratina hidrolisada 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.
O que é realmente necessário
Para além da folha de especificações - as razões operacionais pelas quais as equipas de aquisição nos procuram.
Armazém nos EUA - Sem fricção na importação
O stock nacional significa que não há atrasos no desalfandegamento, não há exposição ao frete marítimo e não há despesas com documentação de importação. As encomendas são enviadas em 48-72 horas a partir da confirmação do pagamento, com rastreio completo a partir do nosso ponto de entrega nos EUA.
Documentação pronta antes da encomenda
COA, MSDS, declaração de alergénios e folha de especificações estão disponíveis mediante pedido - antes de qualquer compromisso de compra. As suas equipas de regulamentação e de controlo de qualidade podem rever tudo antecipadamente, reduzindo o seu ciclo de integração.
Qualidade consistente dos lotes
As nossas instalações GMP em Hefei têm linhas de produção dedicadas para ingredientes de proteína hidrolisada. Cada lote é testado com base no mesmo conjunto de especificações - não está a comprar variabilidade do mercado à vista, está a comprar um padrão de ingredientes repetível.
Volume flexível para marcas em crescimento
Não forçamos grandes MOQs em marcas que ainda estão a crescer. Quer esteja a validar uma nova SKU ou a executar o seu terceiro ciclo de produção, estruturamos as encomendas de acordo com a sua cadência de compras real, não com a nossa.

Perguntas mais frequentes
As perguntas que mais recebemos dos contactos de I&D, aprovisionamento e garantia de qualidade antes de uma primeira encomenda.
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.
