  Purpose

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


Condition Intervention
Inflammation
Dietary Supplement: Glucosamine and Chondroitin
Dietary Supplement: placebo

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Official Title: Glucosamine and Chondroitin Effects

Further study details as provided by Fred Hutchinson Cancer Research Center:

Primary Outcome Measures:
  • hsCRP [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    hsCRP is a biomarker of systemic inflammation


Secondary Outcome Measures:
  • untargeted (exploratory) serum metabolomics (differences in small molecule abundance ratios) [ Time Frame: 1 year ] [ Designated as safety issue: No ]
    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.

Experimental: Glucosamine and Chondroitin
Glucosamine and Chondroitin
Dietary Supplement: Glucosamine and Chondroitin
Glucosamine (1500 mg) and Chondroitin (1200 mg)
Other Name: Nutramax
Placebo Comparator: Placebo
Inactive ingredients
Dietary Supplement: placebo

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.
