- Product Description
Chondroitin Sulfate Powder for the Best Joint Health
Shaanxi Hongda Phytochemistry Co., Ltd. makes high-quality Chondroitin Sulfate Powder, which is an important part in keeping cartilage and joints healthy. We meticulously extract our product from high-quality bovine or marine cartilage using enzymatic hydrolysis. Then, we use advanced purification methods to make sure it is as safe and bioactive as possible.
Our product has a purity of at least 90% (HPLC-verified) and a molecular weight range of 15,000 to 30,000 Da, which makes it easier for your body to absorb and work. People use it a lot in:
- Dietary nutrients that help with osteoarthritis and joint mobility
- Veterinary products that help keep animal joints healthy
- Cosmetic uses for keeping skin moist and flexible
Each batch goes through stringent quality control, which includes testing for heavy metals and microbes, and comes with a full Certificate of Analysis (CoA). Our Chondroitin Sulfate Powder is made in cGMP- and ISO 9001-certified facilities that meet Halal and Kosher regulations around the world.

Why pharmaceutical companies choose our chondroitin sulfate
- Guaranteed Purity: Independent labs have confirmed that the active level is 95–98%.
- Following the rules set by the USP, EP, and JP pharmacopeias is what global compliance means.
- Shots are safer to use when the quantities of endotoxins are lower (<0.1 IU/mg).
- Consistency between batches: keeping the molecular weight between 15,000 and 30,000 Da.
- Audit-Ready: Complete DMF/CEP documentation available
Chondroitin Sulfate Powder: Advanced Manufacturing | Precision Engineering for Purity
Our chondroitin sulfate powder is manufactured through a rigorous 5-stage process:
Raw Material Preparation
We start with carefully selected bovine trachea or shark cartilage from certified suppliers. All materials undergo veterinary inspection and BSE/TSE risk assessment before processing.
Extraction and Cleaning
Food-grade proteases are utilized to break down the cartilage matrix when the pH (7.0–8.5) and temperature (45–55°C) are kept in check.
Multi-stage filtering gets rid of proteins and other things that shouldn't be there.
Ethanol precipitation separates chondroitin sulfate molecules from one another.
Ion-exchange chromatography makes the product even better.
Final Processing
- Ultra-filtration changes the molecular weight to the best range of 15,000 to 30,000 Da.
- Spray drying at low temperatures keeps bioactivity.
- Milling makes the particle size even (80–120 mesh), which helps with formulation.
Quality Control
Every batch undergoes:
- HPLC purity check (≥95%)
- Screening for heavy metals (Pb<0.5ppm, As<0.2ppm)
- Microbial testing (TPC<100 CFU/g)
- Analysis of endotoxins (<0.1 EU/mg)
