Doctor’s Best Glucosamine/Chondroitin/MSM featuring OptiMSM® supports joint structure‚ function and comfort. It is a potent combination of three clinically proven‚ purified ingredients that help the body manufacture proteoglycans in healthy joints. Proteoglycans contribute to the maintenance of sound joint structure‚ ultimately enhancing healthy joint function.

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. Doctor’s Best glucosamine is purified and then sulfated and stabilized with potassium chloride. It is processed to remove residues of protein and impurities‚ yielding pure glucosamine sulfate as the final material. Chondroitin sulfate is a chemical in cartilage around joints in the body.

Chondroitin sulfate is manufactured from bovine cartilage. Doctor’s Best uses chondroitin sulfate with a purity of 90 percent or greater. Quality assurance testing is performed using sophisticated laboratory analytical methods.

MSM is an excellent dietary source of bioavailable organic sulfur. Doctor’s Best MSM features OptiMSM®‚ a highly purified form (99.9% pure) of methylsulfonylmethane (MSM). Since the amount of MSM found naturally in living materials is too small to be extracted‚ the MSM used for dietary supplements is synthesized. The makers of OptiMSM® developed a four-stage process to separate impurities including heavy metals and other contaminants and is 99.9% pure MSM. Each batch exceeds the United States Pharmacopeia (USP) monograph standards for MSM‚ and is validated by testing in independent laboratories.

      I was recommended this product by a friend who knows her supplements! They are easy to swallow & after a month I do believe they are helping with my hip joint pain. I’ll continue to take them hoping they will work along with all the things I’m doing to aid in joint health.
