Glucosamine and chondroitin are major components of cartilage that support the joints. They have been shown in clinical studies to support healthy cartilage and joint function. (1-3)

Glucosamine

• Glucosamine is an important component of cartilage and a key element for joint function and repair. 
• It is naturally produced by our bodies, but the amount decreases as we age. As a result, cartilage in areas such as the knees, hips, and hands begins to dry out, until it hardens. That, in turn, creates joint discomfort and stiffness.
  
• An analysis of multiple randomized controlled trials found that glucosamine supplementation helps support healthy joint structure and encourages comfortable knee function. (2)

Chondroitin

• Chondroitin is a major natural component of cartilage. It contains essential building blocks for healthy comfortable cartilage and helps to stimulate its production.
  
• Acting as a carrier of liquid nutrient to the joints, it supports healthy fluid balance for better joint movement and mobility.
• 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)
