Undenatured Type II Collagen (UC-II-style) is a food-grade minimally processed, native-structure collagen from chicken sternum cartilage, working via oral tolerance mechanism at low doses (40 mg/day) to support joint health, mobility and cartilage preservation.We supply bulk Undenatured Type Ii Collagen sourced from leading China manufacturers, available in powder form for food and beverage manufacturers worldwide. Our Undenatured Type Ii Collagen is widely used in premium joint-health supplements, osteoarthritis management products, active-aging formulas, veterinary joint supplements and rheumatoid arthritis support.
Undenatured Type II Collagen is produced by low-temperature enzymatic extraction of chicken sternum cartilage without heat denaturation.
It preserves the native triple-helix structure and conformational epitopes. Acting via oral tolerance in Peyer's patches, it modulates immune response and reduces cartilage auto-immune attack at remarkably low doses (40 mg/day), clinically validated for osteoarthritis and joint-mobility benefits.
