Description
The sodium salt form of chondroitin sulfate, the standard pharmacopoeial form used in veterinary medicinal products and premium pet joint supplements where defined molecular weight, salt-form consistency, and pharmacopoeial documentation are required.
White to off-white free-flowing powder. Highly water-soluble with consistent dissolution behavior across batches, an advantage in liquid pet supplement formulations and injectable veterinary products.
We supply pet-grade, food-grade, and pharmaceutical-grade Chondroitin Sulfate Sodium from manufacturers in China holding ISO, Halal, Kosher and other certifications relevant to the product and production. Bovine, porcine, chicken, and marine source documentation provided on request.
Common market grades include 90 percent and 95 percent assay food and supplement grades, USP and EP pharmacopoeial grades for veterinary medicinal use, and low-molecular-weight chondroitin sulfate sodium for enhanced-absorption joint products.
Bulk and reduced-MOQ shipments. Batch-level COA covering assay, intrinsic viscosity, sodium content, sulfate ratio, protein, heavy metals, and microbiology.
Introduction
Chondroitin Sulfate Sodium is the form of chondroitin sulfate listed in major pharmacopoeias including USP and EP, and is the reference material for veterinary medicinal joint formulations in regulated channels. The sodium counter-ion is what the polymer carries naturally in vivo, where it is bound to the proteoglycan aggrecan in cartilage.
Industrial production starts from cartilage of bovine trachea, porcine, chicken keel bone, or shark, depending on intended end use and customer allergen requirements. Tissue is digested under controlled alkaline and enzymatic conditions, the resulting glycosaminoglycan is purified by ion exchange and precipitation, and the sodium salt is crystallized or spray-dried.
The veterinary literature on chondroitin in osteoarthritic dogs and horses spans four decades and supports the use of chondroitin-glucosamine combinations as nutraceuticals for joint maintenance and chronic-pain management. AAFCO supplement classifications in North America and corresponding frameworks in the EU, UK, Japan, Australia, and New Zealand accommodate the ingredient in pet supplements and feed additives.
For B2B procurement the principal specification points beyond assay are intrinsic viscosity (a proxy for molecular weight, which affects absorption and bioavailability claims), protein content (a quality indicator reflecting purification thoroughness), and species and tissue documentation for allergen disclosure and customs classification.
Where it is used
- Veterinary medicinal joint products requiring USP or EP pharmacopoeial-grade chondroitin
- Premium glucosamine-chondroitin-MSM joint supplements for senior dogs and cats
- Liquid joint supplement formulations where dissolution consistency is critical
- Equine intra-articular and oral joint-support products
- Veterinary post-surgical and rehabilitation nutraceutical blends
- Soft-chew and palatable-powder pet supplements where defined particle behavior is required
- Therapeutic kibble premixes for prescription joint-support diets
- Hypoallergenic joint supplements with documented single-species sourcing
