glucosamine and chondroitin sulfate for joints and bones

Glucosamine and chondroitin sulfate are substances found naturally in the body. Glucosamine is a form of amino sugar that is believed to play a role in cartilage formation and repair. Chondroitin sulfate is part of a large protein molecule (proteoglycan) that gives cartilage elasticity. Glucosamine and chondroitin are two molecules that make up the type of cartilage found within joints. Inside our joints, cartilage undergoes a constant process of breakdown and repair. Glucosamine is a naturally occurring body chemical, which the body uses to produce cartilage, tendons and ligaments; which are the connective tissue for joints. Glucosamine is a precursor to a molecule called a glycosaminoglycan-this molecule is used in the formation and repair of cartilage. Chondroitin is a naturally occurring body chemical that works in cartilage in a different way to glucosamine. It helps to attract water into the structure of the cartilage, which is essential for maintaining the cushioning effect between the joints, and bringing in nutrients to the cartilage, as it does not have its own blood supply. Chondroitin supplements increase the chondroitin levels in cartilage tissue. Cartilage is the body’s shock-absorber and joint lubricant. It covers the ends of any bones that meet together, and stops the hard bone tissue rubbing together, which would be very painful. Osteoarthritis occurs when the cartilage covering the ends of the bone thins to such an extent that the ends of the bones come close together or touch. This produces pain and stiffness. Glucosamine and chondroitin supplements can help reduce the loss of cartilage, and can help to repair the cartilage structure, where it is still intact. They can help with pain and stiffness.
