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.

Where is Chondroitin sulfate used?

• Dietary supplements: primary active ingredient in joint health capsules, tablets, and softgels
• Combined with glucosamine for cartilage support claims in consumer health products
• Ophthalmic preparations: viscoelastic solutions for ocular surgery and eye drops requiring viscosity and lubrication
• Sports nutrition: recovery products targeting mobility and joint comfort
• Functional food and nutraceutical powder blends and stick packs for bone and joint health
• It also functions as a structural component in connective tissue.

Good to know: Source traceability and purity documentation are key procurement considerations; source documentation is increasingly required by buyers for regulatory and labeling compliance in international markets.

Commercial specifications

• Purity levels typically range from 90% to 95% chondroitin sulfate content depending on the specific application
• Standard grades include USP, BP, and food-grade specifications for global distribution
