Mythocondro is a high-purity, lower molecular weight (LMW) chondroitin sulfate (CS) produced by bacterial fermentation. Mythocondro (Lower MW: 5,000-12,000 daltons) showed 43% higher oral bioavailability compared to animal source CS (High MW: 20,000-64,000 daltons) in a clinical study that demonstrated the effectiveness of 600 mg of Mythocondro compared to 1,500 mg of animal source Chondroitin Sulfate. This vegan formula provides Mythocondro and Glucosamine, both derived from bacterial fermentation. Chondroitin Sulfate and Glucosamine are essential components of joint tissue and essential for the production of hyaluronic acid (HA). HA is a major component of skin and synovial fluid, which lubricates the joints. For best results, use with Jarrow Formulas JarroSil, the biologically Activated Silicon.
