Product Description
Food Eye Drops Medical Grade Health Care Supplement Gel Glucosamine Hyaluronic Acid Chondroitin Sulfate Powder


Chondroitin sulfate can reduce pain in patients with osteoarthritis, improve joint function, reduce joint swelling and fluid accumulation, and prevent gap narrowing in the knee and hand joints. Provide cushioning effect, alleviate impact and friction during movement, absorb water into proteoglycan molecules, thicken cartilage, and increase synovial fluid volume in joints. One of the important functions of chondroitin sulfate is to serve as a transport channel, delivering important oxygen and nutrients to the joints, helping to remove waste from the joints, while also eliminating carbon dioxide and waste. Due to the lack of blood supply to articular cartilage, all oxygenation, nourishment, and lubrication come from synovial fluid.
