Official title
Effects of Glucosamine and Chondroitin Supplementation in Women With Knee Osteoarthritis Participating in an Exercise and Weight Loss Program: a Randomized Placebo Controlled Clinical Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Background: Exercise, weight loss, and dietary supplementation of glucosamine and chondroitin (GC) have been reported to improve functional capacity in individuals with knee osteoarthritis (OA). The purpose of this study was 1.) to determine whether women with knee OA who follow a higher protein diet observe more favorable changes in body composition and/or markers of health compared to those following a standard higher carbohydrate-based diet; and, 2.) to determine whether dietary supplementation of glucosamine and chondroitin during a weight loss and fitness program lessens symptoms of pain, improves functional capacity, and/or promotes greater health benefits in women with knee OA. It was hypothesized that both groups would experience beneficial changes in body mass, body composition, and markers of health. However, greater benefits would be observed in those following a higher protein diet while supplementing the diet with glucosamine and chondroitin.
