Combination of Glucosamine and Chondroitin Found To Have Joint Health Benefits
Glucosamine and chondroitin are popular supplements for easing joint pain. A recent study has found that a combination of the two may reduce narrowing of the joint space in the knee, further adding to the body of scientific evidence backing their usage.
Participants in the study included 605 people with chronic knee pain and evidence of narrowing of the knee joint. Over the course of two years they were assigned one of four daily interventions:
1. 1500 mg of glucosamine;
2. 800 mg of chondroitin sulfate;
3. a combination of 1500 mg glucosamine and 800 mg chondroitin sulfate;
4. a placebo.
At the conclusion of the study, the combined glucosamine, sulfate supplement was correlated with significant reductions in joint space narrowing when compared with the placebo. When taken individually, glucosamine and chondroitin did not have any effect.
A narrowing of the joint space indicates worsening osteoarthritis, and has been equated with loss of articular cartilage.
The research was led by researchers at the University of Sydney in Australia. It was published online ahead of print on January 6, 2014.
Glucosamine is produced naturally in the body and helps with joint function. Glucosamine supplements have been found to help with osteoarthritis, reducing joint pain and improving joint function.
Chondroitin is found in and around the cells of cartilage, and provides cartilage with strength and resilience. Previous research has found that chondroitin may help ease the pain of arthritis and osteoporosis, lower cholesterol and possibly help with ulcerative colitis and Crohn’s disease.
