About Doctor’s Best – Glucosamine Chondroitin MSM with OptiMSM – 360 caps
Doctor’s Best Glucosamine Chondroitin MSM with OptiMSM combines three widely researched ingredients in a single, high-potency formula. Each serving of four capsules delivers 1500 mg of Glucosamine Sulfate 2KCl, 1200 mg of Chondroitin Sulfate, and 1000 mg of MSM sourced from OptiMSM — a premium, purified form of methylsulfonylmethane produced in the USA. With 90 servings per container, this 360-capsule pack provides a generous three-month supply, making it a practical choice for consistent, long-term use.
Glucosamine and chondroitin are naturally occurring compounds found in healthy cartilage and connective tissue. MSM (Methylsulfonylmethane) is an organosulfur compound present in many foods and widely used in food supplements. Doctor’s Best selects OptiMSM as its MSM source for its high purity and consistent quality, backed by the manufacturer’s own safety and quality testing programme.
Doctor’s Best is a science-based supplement brand founded in 1990 by physicians. The brand is committed to using ingredients backed by published scientific research and to formulating products that meet rigorous quality standards. Glucosamine Chondroitin MSM with OptiMSM reflects this philosophy, bringing together three established ingredients in meaningful amounts within a convenient daily capsule format.
