3Chondroitin sulfate appears in 3 protocols personalizable→Sulfated glycosaminoglycan (GAG) · primary structural component of hyaline articular cartilage (along with collagen II and hyaluronic acid).
Chondroitin sulfate (CS) is a sulfated glycosaminoglycan (GAG) · repeating disaccharide chain (N-acetylgalactosamine + glucuronic acid) with sulfate groups. It is one of the primary structural components of hyaline articular cartilage: combines with core proteins (aggrecan) forming proteoglycans · these bind hyaluronic acid → hydrated compressible cartilaginous ECM matrix. Without sufficient CS: dehydrated cartilage + mechanical fragility → OA.
Supplementation: bovine/porcine/marine chondroitin sulfate hydrolyzed · molecular weight 10-50 kDa (bioactive CS). Canon strain: Condrosan (Bioiberica, Spain) = bovine pCS purified pharmaceutical standard · used in Reginster, Möller, Singh canon EULAR RCTs. Nature-source bovine CS-Bio with homogeneous 4/6-O sulfation. Mechanisms: MMP-13 inhibition (main matrix metalloproteinase of cartilage degradation) → cartilage preservation · NF-kB anti-inflammatory → reduces IL-1β, TNF-α, IL-6 synovitis · endogenous chondrocyte proteoglycan synthesis stimulation. Singh 2024 meta n=4,382: CS 800-1200 mg × 6 months → WOMAC pain −35%, function +28%, synovitis −22%. Möller 2010 RCT 6 months: CS preserves tibio-femoral joint space vs placebo. Hochberg MOVES 2024 (extension): pCGS 1500 + CS 1200 = NON-inferior to celecoxib 200 mg in severe OA.
