Chondroitin sulfate

Chondroitin sulfate (CAS 9007-28-7), commonly abbreviated as CS, is a sulfated glycosaminoglycan derived primarily from bovine, porcine, or marine cartilage sources. It functions as a structural component in connective tissue and is commercially processed into standardized active ingredients.

In dietary supplement manufacturing, CS is a primary active ingredient in joint health formulations such as capsules, tablets, and softgels. It is frequently combined with glucosamine to target cartilage support claims in various consumer health products.

Pharmaceutical-grade CS is used in ophthalmic preparations, including viscoelastic solutions for ocular surgery and eye drop formulations requiring viscosity and lubrication. These applications demand high purity and strict adherence to manufacturing protocols.

Sports nutrition brands incorporate it into recovery products targeting mobility and joint comfort, where source traceability and purity documentation are key procurement considerations. This ensures the final product meets athlete safety standards.

Functional food and nutraceutical producers also use CS in powder blends and stick packs positioned for bone and joint health categories. The ingredient provides versatility for manufacturers looking to expand their wellness product lines.

Chondroitin sulfate is supplied as a white to off-white powder in varying particle sizes suited to direct compression or encapsulation. Standard grades include USP, BP, and food-grade specifications for global distribution.

Purity levels typically range from 90% to 95% chondroitin sulfate content depending on the specific application. Bovine, porcine, and shark-derived grades are available to meet diverse formulation requirements and consumer preferences.

Source documentation is increasingly required by buyers for regulatory and labeling compliance in international markets. This transparency ensures that the raw materials meet the necessary safety and quality benchmarks for the industry.
