Glucosamine and Chondroitin Effects

Not Applicable
Completed
Conditions
Inflammation
Interventions
Dietary Supplement: Glucosamine and Chondroitin
Dietary Supplement: placebo
Registration Number
NCT01682694
Lead Sponsor
Fred Hutchinson Cancer Center
Brief Summary

A common starting dose of glucosamine and chondroitin will reduce inflammation as reflected by a reduction in serum C-reactive protein.

Detailed Description

Use of glucosamine and chondroitin have been associated with reduced cancer and overall mortality. The aim of this study is to determine whether a common starting dose of glucosamine and chondroitin (1500 mg/d + 1200 mg/d, respectively) reduces systemic inflammation as reflected by a reduction in high sensitivity C-reactive protein.

Primary Outcome Measures
NameTimeMethod
hsCRP1 year

hsCRP is a biomarker of systemic inflammation

Secondary Outcome Measures
NameTimeMethod
untargeted (exploratory) serum metabolomics (differences in small molecule abundance ratios)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.
