untargeted (exploratory) serum metabolomics (differences in small molecule abundance ratios)
Time Frame: 1 year
|
The mechanisms of action of glucosamine and chondroitin are currently unknown.
Untargeted metabolomic assays of serum will be undertaken for exploratory analyses of potential effects of glucosamine and chondroitin.
Significant differences in abundance ratios of small molecules between the intervention and placebo will be reported.
