Both of these compounds make up normal human cartilage. Of course, cartilage is essential to bones and joints because it is effectively the cushion between them. There have been many research studies that have demonstrated that the combination of glucosamine and chondroitin work synergistically to combat osteoarthritis (or at least it’s symptoms). Strengthening joints and cartilage is extremely important to athletes because of the constant stress placed on them during high performance activities like resistance training.
