Product Overview
Chondroitin Sulfate Sodium is the sodium salt form of chondroitin sulfate, a natural glycosaminoglycan extracted from animal cartilage tissue. It is a widely used nutritional ingredient for joint health dietary supplements. The raw material sources include bovine cartilage, porcine cartilage and shark cartilage. As one of the key structural components of articular cartilage, it helps maintain cartilage structure and supports joint cushioning. This product is usually white or off-white powder with good water solubility. It is commonly combined with glucosamine in joint care formulas, and can be formulated into tablets, capsules, powder blends and other supplement forms to support joint comfort and mobility.
