617:. It enters all tissues, reaching cartilage within two hours. When PSGAG reaches the synovial fluid, it is then taken up by the cartilage matrices, with osteoarthritic cartilage showing a stronger preference for taking it up. It reaches its peak levels in the joints at 48 hours, and lasts up to 96 hours, before leaving and being excreted by the

studies have shown it to inhibit the enzymes that degrade cartilage and bone, as well as suppress inflammation and stimulate the synthesis of replacement cartilage. While it can cause an increased risk of bleeding, it is relatively safe and has a high

PSGAG also stimulates the synthesis of glycosaminoglycans, hyaluronic acid, and collagen, which increase synovial viscosity. It cannot, however, completely reverse the disappearance of cartilage, nor can it reverse bone loss caused by arthritis.

In degenerative joint disease, the proteoglycan complexes start disappearing, and the hyaluronate becomes poorer in quality and scarcer. This lowers the viscosity of the synovial fluid (which increases friction) and causes

While it is widely used, some studies still show conflicting results in terms of efficacy, causing some to claim that PSGAG is not solely responsible for the significant mitigation of arthritis seen in success cases.
