Solgar proudly introduces Extra Strength Glucosamine Chondroitin MSM with Ester-C Tablets. Three tablets daily provide 60 mg of vitamin C (as Ester-C, calcium ascorbate), 1,500 mg of glucosamine sulfate, 1,200 mg of sodium chondroitin sulfate, and 700 mg of MSM (as methylsulfonylmethane, OptiMSM™). This synergistic formula is specifically designed to help support joint and cartilage health. Glucosamine is a key structural component of cartilage and plays a role in the maintenance of joints. Chondroitin is also a major constituent of cartilage and provides structural support for cartilage and joints. MSM delivers a methylated form of sulfur to the body. This form is important for joint health because it helps to maintain the structure of connective tissue. Vitamin C is beneficial for the health of joints because it plays a key role in collagen formation and maintenance. This formula offers Ester-C, a highly absorbable, non-acidic form of vitamin C that is gentle on the stomach. Studies suggest that glucosamine sulfate, chondroitin sulfate, and MSM have positive effects on joint healh. Research also indicates that a combination of glucosamine and MSM may offer better joint support than when utilized individually.
