Doctor's Best Glucosamine Chondroitin MSM, 120 Capsules Features : Supports Joint Structure, Function, and Comfort Glucosamine sulfate (GS) helps to maintain joint health through its ability to both act as a component of and stimulate formation of cartilage glycosaminoglycans and the hyaluronic acid backbone essential for the formation of cartilage proteoglycans. research also backs the ability of GS to influence joint comfort. This product contains no: milk, egg, wheat, gluten, corn, soy, sugar, sweeteners, starch, salt, or preservatives. MSM improves the body's resistance to adverse physical stress. Doctors Best Glucosamine Sulfate contains pure glucosamine sulfate, as confirmed by HPLC testing. Glucosamine sulfate consists of glucosamine, an amino sugar extracted from "chitin," a component of shellfish skeletons. ("Chitin," the resilient polysaccharide that forms the structural framework of animal shells, is a long-chain polymer consisting of many glucosamine molecules linked together.) The purified glucosamine is then sulfated and stabilized with potassium chloride.Glucosamine sulfate is derived from the shells of ocean-growing shellfish. It is processed to remove all residues of protein and impurities, yielding pure glucosamine sulfate as the final material. Glucosamine/Chondrotin/MSM contains chondroitin sulfate with a purity of 90 percent or greater. Quality assurance testing is performed using two sophisticated laboratory analysis methods: 1) HPLC and 2) C.P.C. Titration, a newly developed method now accepted as the most definitive test for chondroitin sulfate. Glucosamine/Chondroitin/MSM features OptiMSM methylsulfonylmethane, MSM distilled to be 99.9% pure. A biological compound that occurs in the human body and in some foods, MSM is an excellent dietary source of bioavailable organic sulfur. The MSM Story-One of Nature's Primary Sources of Organic Dietary Sulfur!The human body requires a continuous supply of usable sulfur, and MSM is one of the primary organic sulfur-containing molecules for use by living organisms. From life's earliest beginnings, primitive marine organisms (blue-green algae and phytoplankton) have absorbed inorganic sulfur from ocean waters and produced organic sulfur molecules, primarily dimethyl sulfonium salts. These salts are released back into the sea, where they are converted to dimethyl sulfide, which readily evaporates, ending up in the upper atmosphere. Dimethyl sulfide is then oxidized by UV light, forming DMSO and MSM. The two compounds are delivered to land masses in rain water, and absorbed by plants. MSM is a stable end product of this process, serving as a primary source of sulfur in the food chain.
