Glucosamine and chondroitin have been shown in clinical studies to support healthy cartilage and joint function.1-3 Glucosamine is an important component of cartilage, and an analysis of multiple randomized controlled trials found that glucosamine supplementation helps support healthy joint structure and encourages comfortable knee function.2
Chondroitin also contains essential building blocks for healthy comfortable cartilage. Similarly, a comprehensive review of studies on chondroitin supplementation found that it also helps maintain healthy joints and supports joint comfort.4
Results from a six-year trial using the combination of glucosamine and chondroitin showed that in those who used the combined supplement for greater than two years, there was a significant preservation of healthy joint structure.5
