Chondroitin Sulfate

Joint Supportoral · inferred

Glycosaminoglycan found in cartilage. Often combined with glucosamine for joint health. Helps retain water in cartilage and inhibits degradative enzymes.

Research behind this entry

  1. Chondroitin for osteoarthritis Singh JA et al. · Cochrane Database of Systematic Reviews, 2015 DOI

    Cochrane review of 43 RCTs found chondroitin (alone or combined with glucosamine) provided small-to-moderate improvement in joint pain and function in osteoarthritis.

  2. Effect of chondroitin sulphate in symptomatic knee osteoarthritis: a multicentre, randomised, double-blind, placebo-controlled study Kahan A et al. · Annals of the Rheumatic Diseases, 2009 DOI

    Large multicenter RCT of 622 patients found chondroitin sulfate (800 mg/day for 2 years) significantly reduced joint space loss and improved pain compared to placebo.

  3. Structural and symptomatic efficacy of glucosamine and chondroitin in knee osteoarthritis: a comprehensive meta-analysis Zhu X et al. · Archives of Physical Medicine and Rehabilitation, 2018 DOI

    Meta-analysis found chondroitin significantly reduced joint space narrowing (structure modification) and improved pain scores in knee osteoarthritis trials.
