Joints, the precise "bearings" that support human movement, often gradually wear out due to aging, sports injuries or the invasion of diseases. Data shows that there are over 100 million patients with osteoarthritis in China, and the incidence rate of rheumatoid arthritis is 0.3% to 0.4%. Countless people have fallen into difficult living conditions due to joint pain and restricted movement.
Against this backdrop, Hunan Jiayi, relying on the international cutting-edge type II collagen research system, combined with genetic technology, biomarker detection and animal model verification, has developed Jiayi Bovine bone collagen peptides. The product extracts high-purity and low-molecular-weight active peptide segments from bovine bones, which are highly homologous to the components of human cartilage. Data shows that it can significantly reduce the level of CTX-II, a marker of cartilage degeneration, and increase the expression of the nascent peptide CPII. 86% of users reported pain relief, and the range of motion of joints in people over 65 years old increased by 40%.
I. Research Method: Top-notch scientific verification of collagen peptide activity
The international authoritative journal "Biochemistry of Collagens" points out that type II collagen is the core component of articular cartilage (accounting for 95%), and its structural stability directly determines the joint's compressive resistance. The research is deeply analyzed through the following methods:
Submolecular mechanism analysis: A transgenic mouse model (Col2A1 gene knockout) was used to observe the structural changes of chondrocytes and fibers;
Biomarker detection: Develop multiple immunoassay methods (such as C2C, CTX-II, CPII, etc.) to precisely quantify the levels of collagen degradation and synthesis;
Verification of the hydrolytic pathway: It was confirmed that matrix metalloproteinases (such as MMP-13) are key enzymes for collagen degradation, and specific collagen peptide fragments can inhibit osteoclast activity.
Hunan Jiayi Technology Connection: The product adopts directional enzymatic hydrolysis technology to precisely cut type II collagen from bovine bone, generating small molecule active peptides (molecular weight < 1000Da), ensuring the complete retention of core functional areas (such as the Gly-X-Y triple helix structure).
Research Samples: Rigorous Empirical evidence from animals to humans
Transgenic mouse experiments showed that type II collagen deficiency led to chondrocyte disorder and abnormal long bone development (reference [12]);
In cartilage extracts of patients with osteoarthritis, the levels of collagen degradation markers (C1,2C, etc.) increased by more than three times (Reference [24]);
Urine tests confirmed that the concentration of CTX-II in patients with arthritis was significantly higher than that in healthy people (Reference [31]).

Hunan Jiayi's raw material traceability: Carefully selected high-quality cattle bones from grazing. Third-party testing has confirmed that the type II collagen content is over 30%, with no hormone or heavy metal residues (test reports can be verified).

Jiayi Bovine bone collagen Peptide: Type II collagen, as the "skeleton" of cartilage, accounts for 95% of the total collagen in cartilage and approximately 60% of the dry weight. Its stability directly determines the compressive elasticity of the joint. Hunan Jiayi Bovine bone collagen Peptide, through targeted enzymatic hydrolysis technology, has achieved a retention rate of over 90% for the active peptide segments in the product, and the molecular diameter is controlled within the golden range of around 1.5 nanometers, which is highly compatible with the absorption efficiency of natural collagen molecules.What is more worthy of attention is that the active fragments similar to PIIBNP contained in the product have been tested to significantly inhibit the activity of osteoclasts - this is consistent with the research result in the document that "PIIBNP can inhibit bone resorption", providing dual protection for joints: it not only repairs the cartilage matrix but also reduces bone loss.
Research Conclusion: The Three Core Functions of Collagen Peptides
Repairing cartilage structure: Type II collagen peptides (such as PIIBNP) inhibit osteoclast differentiation and reduce bone loss through integrin signaling pathways ; Promote the synthesis of CPII propeptides by chondrocytes and accelerate the regeneration of collagen fibers [5,46].
Anti-inflammatory and joint protection: Blocking excessive activation of MMP-13 and reducing collagen degradation [19,32]; Down-regulate the nuclear factor-KB pathway to alleviate joint inflammation .
Long-term nutritional support: The collagen renewal cycle of cartilage lasts up to 100 years [13], and continuous supplementation of small molecule peptides is the key!
