  • This formula provides a powerful combination of three researched, purified ingredients to support the production of proteoglycans in joints.

Must have ingredients for joyful joints
Doctor's Best Glucosamine Chondroitin MSM contains pure glucosamine sulfate, as confirmed by HPLC testing. Glucosamine sulfate supports joint health for joint lubrication, joint movement and flexibility. Glucosamine sulfate is extracted from chitin, a long-chain polymer consisting of many glucosamine molecules linked together. Chitin forms structural frameworks in many living things, including aquatic crustaceans such as lobsters, crabs and shrimp. In this formula, the glucosamine is purified and then sulfated and stabilised with potassium chloride. Cartilage, composed of proteoglycans, is mainly located on bones, near the joints and consists primarily of collagen protein with side chains called chondroitin sulfate. Doctor's Best Glucosamine Chondroitin MSM contains chondroitin sulfate with a purity of 90% or greater. Quality assurance testing is performed using two sophisticated laboratory analysis methods: High-Performance Liquid Chromatography (HPLC), and Cetyl Pyridinium Chloride (CPC) Titration. MSM is a biological compound occuring in the human body and in some foods; it supplies bioavailable organic sulfur needed to support joint health, hair skin and nails. OptiMSM® methyl-sulfonylmethane is MSM distilled to be 99% pure.
