According to convincing research, glucosamine sulfate may take a part supporting healthy joints.* By providing joints with the essential raw materials, glucosamine sulfate can support joint health.* Research suggests that it is absorbed into the body at a rate much more effective than other "joint-supporters".* Because of the small size of the molecules, they are absorbed at a rate of 98%--compare that to the mere 13% absorption rate of chondroitin sulfate, and you can understand why glucosamine sulfate works so much better. By stimulating production of additional synovial fluid, glucosamine sulfate helps keep joints in the body rolling smoothly.* Recent studies suggest that as a readily absorbed building block for cartilage, glucosamine sulfate works as a supporter of cartilage in humans.*

Current research suggests that supplemental Glucosamine and Chondroitin Sulfate can be useful for individuals to support joint health.* Optimum Nutrition's Glucosamine Plus CSA contains 1000 mg of pure crystalline Glucosamine Sulfate (Type A) per two capsules, the ratio recommended by many health care experts. The Extra Strength Tablets version has 1500 mg of Glucosamine and 1200 mg of Chondroitin!
