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
