Yes it is possible to rebuild cartilage of the joints with glucosamine sulfate but the time it will take to rebuild it depends on the nature of your body. Cartilages are very important in human body to prevent the deterioration of joints. As we grow older, the amount of calcium in the body goes on reducing resulting in cartilage getting damaged as time passes. As a result of it the joints will rub against one another resulting in heavy pain. Cartilages are important in several parts of body such as discs of the spine, ear and nose. Cartilage also acts as shock absorbers and prevents bones from rubbing with one another.

Glucosamine contains electrically charged sulfates that provide compression property to the cartilage. Glucosamine gets rapidly absorbed into the blood stream buts its excessive intake can be harmful as it will get deposited into the organs like liver and kidney. Glucosamine imparts strength and rigidity to the cartilage. Glucosamine sulfate makes the matrix of the tissues stable and flexible Osteoarthritis results in breakdown of cartilage and since glucosamine is a substance that is found in cartilage so it is believed that glucosamine will help to rebuild cartilage.
