Chondroitin sulfate

Chondroitin sulfate (CAS 9007-28-7) is a sulfated glycosaminoglycan composed of repeating disaccharide units, sourced primarily from bovine or porcine cartilage. It is also referred to as chondroitin sulphate, Chondroitin Q, and chondroitinsulfates. No E-code is assigned, as it is not classified as a food additive.

In pharmaceutical formulations, chondroitin sulfate is used as an active ingredient in joint health products, where it inhibits cartilage-degrading enzymes and supports synovial fluid viscosity. In nutraceutical and functional food applications, it acts as an antioxidant and structural stabilizer, protecting sensitive formulations from oxidative degradation during processing and storage.

Chondroitin sulfate is available in pharmaceutical-grade (Ph.Eur. compliant) and food-grade (FCC compliant) powder forms. It falls under HS code 39139000 and is subject to REACH registration requirements for EU supply. Sourcing documentation typically includes TSE/BSE certificates of suitability when derived from animal tissue.
