Glucosamine sulfate is a natural joint support found in the fluid around joints. When digested, it stimulates the production of key building blocks that form the cartilage needed for repairing joints. It also protects the existing cartilage and connective tissue of joints and increases cushioning to improve mobility and function. This makes glucosamine sulfate very useful for relieving the painful symptoms of degenerative joint conditions, such as osteoarthritis, and can help slow the progression of joint degeneration.
