DETAILS

Sodium chondroitin sulfate Powder

It is a naturally occurring acidic glycosaminoglycan (GAG), mainly found in animal cartilage, connective tissues, and skin. Its chemical structure consists of repeating units of D-glucuronic acid and N-acetylgalactosamine sulfate esters, with a molecular weight of approximately 10,000 to 50,000. It is usually present in the form of a sodium salt, which has better water solubility and stability.

FUNCTION

Lubricate joint cavities and reduce bone friction

Sodium chondroitin sulfate is an important component of articular cartilage and synovial fluid. It boosts the secretion of synovial fluid inside joints, forming a protective lubricating layer between bones. It directly lowers rigid friction between articular surfaces when walking, climbing stairs or exercising, and relieves joint creaking and stiff sensation.

Repair damaged articular cartilage and maintain cartilage integrity

Cartilage will gradually wear and develop tiny lesions due to aging, long-term heavy load and sports damage. This raw material delivers nutrients to chondrocytes, stimulates chondrocyte proliferation, and promotes the regeneration and repair of damaged cartilage tissue. It slows cartilage thinning and prevents further erosion of joint cartilage.

Alleviate joint swelling and mild inflammatory discomfort

It inhibits the release of inflammatory factors around joints caused by wear and strain. It effectively eases joint swelling, aching and soreness brought by long standing, strenuous exercise or cold stimulation. It improves joint flexibility and helps users restore normal daily mobility.

Prevent bone mineral loss and protect subchondral bone

Sodium chondroitin sulfate can regulate the balance of bone metabolism, reduce excessive bone resorption, and slow the loss of calcium and minerals in subchondral bone. It forms a dual protective system with cartilage for joints, lowering the risk of degenerative joint problems caused by bone density decline in middle-aged and elderly groups.

Application

Core raw material for joint-care oral health supplements

It is the classic primary raw material for joint-protection supplements, usually compounded with glucosamine hydrochloride, calcium carbonate and vitamin D. It is made into joint-care powder, tablets and hard capsules, targeting middle-aged and elderly people, people with joint wear and long-term manual laborers, widely sold in pharmacies and health product stores.

Functional additive for sports nutrition recovery powder

Raw material for functional solid drinks for middle-aged and elderly

Combined with milk calcium, collagen peptide and fruit and vegetable powder, this powder is developed into portable stick-pack solid drinks for joint care. The product has a mild taste, easy to brew and absorb, suitable for middle-aged and elderly groups who dislike swallowing tablets, sold in supermarkets, senior care product stores and cross-border health product channels.

Raw material for animal joint veterinary health products

Feed-grade sodium chondroitin sulfate powder is used to produce pet joint-care nutritional supplements for large dogs, racing horses and working livestock. It relieves pet joint dysplasia, lameness and activity difficulties caused by aging or excessive exercise, and improves the mobility of companion animals and sports livestock.
