Native CT-II®
HS Nutra's proprietary undenatured Type II collagen from chicken sternum cartilage, manufactured under a patented process that preserves the native triple-helical structure, intact polypeptides, and active epitopes required for oral-tolerance efficacy. Active at a low 40 mg daily dose rather than the multi-gram loadings of glucosamine / chondroitin stacks.
CAS Number
9007-34-5
Physical Form
Fine pale-yellow to off-white powder
Typical Assay
Standardized to native (undenatured) Type II collagen content by ELISA
Origins
Chicken sternum cartilage
Purpose and Key Benefits
Supports joint comfort, mobility, and cartilage integrity. Mechanism operates via Peyer's-patch oral tolerance rather than structural substrate — why the effective dose is so low. Multicenter human clinical trial data reported vs. placebo, glucosamine, and chondroitin sulfate. Suitable for human and companion-animal applications.
Applications
Premium joint supplements (low-dose capsules, tablets, granules, gummies), sports-recovery stacks, companion-animal joint products, functional foods
