👉 The grace fluid, also known as synovial fluid, is a vital component of the human musculoskeletal system. It acts as a lubricant and shock absorber within joints, reducing friction between bones during movement and preventing wear and tear. Produced by the synovial membranes lining joint cavities, this viscous fluid also nourishes cartilage, keeps joints hydrated, and facilitates the removal of metabolic waste products. Its unique composition, rich in hyaluronic acid and lubricin, ensures smooth, pain-free motion and supports joint health throughout life.
