Official title
Development of Biomarker and Functional Assessment Tools to Evaluate the Effect of Glucosamine on Joint Structure and Quality of Life
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this study is 1) to develop a biomarker of of cartilage synthesis by determining if there is a relationship between changes in the status of knee cartilage and the amount of a biomarker called CTX-II in urine. 2) We will also characterize people who have experienced cartilage loss and/or reduced functional ability using performance tests and a questionnaire. 3) The administration of glucosamine in a beverage for six months will be used to promote the alteration in cartilage status and improve function in people with mild to moderate joint pain. A secondary goal will be to assess the effect of glucosamine on the skin in a small subset of women.
