Chondroitin Sulfate Sodium is a food-grade glycosaminoglycan extracted from bovine, porcine or bird cartilage.We supply bulk Chondroitin Sulfate Sodium sourced from leading China manufacturers, available in powder form for global food and beverage producers. Our Chondroitin Sulfate Sodium is widely used in joint-health supplements, osteoarthritis management products, recovery, veterinary joint supplements and functional beverages with joint claims.
Chondroitin Sulfate Sodium is produced by alkaline extraction, enzymatic treatment, purification and spray drying of animal cartilage (bovine trachea, porcine or chicken).
Standardised to ≥90% chondroitin purity by CPC titration, it is a key structural glycosaminoglycan of articular cartilage and supports joint lubrication, cartilage maintenance and mobility in osteoarthritis and joint-health applications.
