Chondroitin Sulfate is a naturally occurring glycosaminoglycan (GAG) derived from animal cartilage. As a key structural component of cartilage, it helps maintain the integrity of the cartilage matrix and supports normal joint function. The product is a white to off-white hygroscopic powder that is freely soluble in water and practically insoluble in acetone and ethanol.
As a leading chondroitin sulfate manufacturer, we provide a comprehensive range of sources including bovine, porcine, shark, and avian, plus specialty variants like low molecular weight and high density grades. All products meet USP and EP standards, produced under ISO, GMP, and HACCP quality systems with full traceability. With over 20 years of global export expertise and complete documentation support, we serve as a trusted one-stop partner for nutraceutical and functional food brands worldwide.

Chondroitin sulfate serves as a foundational ingredient in joint health products, including tablets, capsules, and powder blends. It is commonly incorporated into daily supplement regimens targeting adult populations seeking joint structure support and maintenance of joint flexibility.
Sports nutrition brands include chondroitin sulfate in formulations designed for active individuals. The ingredient supports cartilage maintenance in users with regular physical activity, making it suitable for pre-workout, post-workout, and daily wellness product lines.
Chondroitin sulfate demonstrates compatibility with several other active ingredients commonly used in joint health formulations. It can be combined with glucosamine, MSM, collagen peptides, and hyaluronic acid to create multi-component joint support products.
Each batch of chondroitin sulfate undergoes testing using CPC and HPLC methods to verify assay content. The production process includes multiple purification steps to control impurity levels, including heavy metals, residual solvents, and microbial contaminants. Batch-to-batch consistency is maintained through standardized extraction and drying procedures.
Production facilities operate under ISO-certified quality management systems and follow GMP manufacturing practices. Products conform to USP and EP pharmacopeial standards. Halal and Kosher certifications are available for applicable product variants. Full traceability is maintained from raw material sourcing through finished product packaging.
Standard packaging consists of 25 kg fiber drums with double PE inner bags to protect product integrity during storage and transit. Custom packaging options are available to accommodate specific commercial procurement requirements, including different drum sizes, bag-in-box configurations, and private labeling arrangements.
Direct factory supply supports bulk order volumes for enterprise customers. Production capacity accommodates both regular scheduled orders and urgent replenishment requests. With over 20 years of international export experience, we provide complete documentation support including batch-specific COA, TDS, and MSDS, along with logistics coordination for global shipments.
We offer seven product variants sourced from bovine, avian, shark, and porcine cartilage. Specialty variants include Halal-certified, low molecular weight, and high bulk density grades to suit different formulation needs and production processes.
Purity is determined through assay testing using the CPC method on a dry basis, with specifications ranging from 90.0% to 105.0%. Additional purity indicators include electrophoretic purity (≤2%) and limits for nonspecific disaccharides (≤10.0%). Each batch is tested and documented with a certificate of analysis.
