A molecule derived from the sugar glucose by the addition of an amino (NH2) group, glucosamine is a component of a number of structures including the blood group substances and cartilage.

Glucosamine is a nutritional supplement. Glucosamine may improve symptoms of pain and stiffness in some patients with osteoarthritis, according to recent research studies. In one study, glucosamine was compared to ibuprofen (ADVIL, MEDIPREN, MOTRIN, NUPRIN.) Pain relief was more rapid with ibuprofen 400mg three times daily than with glucosamine 500mg three times daily; however, after 4 weeks the relief of symptoms was similar with the two treatments. (Of note, this dose of ibuprofen is not an antiinflammatory dose; higher amounts are typically given.)

Glucosamine nutritional supplement has not been evaluated for other forms of arthritis, such as rheumatoid arthritis.

Glucosamine has been marketed as a "cartilage rebuilder." This is in part under the assumption that, because glucosamine is a component of normal cartilage, consuming it will assist in the rebuilding of damaged cartilage. There is no strong evidence that glucosamine alone, or in combination with chondroitin, is of value in rebuilding cartilage that is damaged by osteoarthritis. It has also received acclaim as a "cure" for arthritis -- for which there is no evidence.

Arthritis, cancer, heart attacks, allergies, bowel disease, Alzheimer’s, and dozens of other conditions all have one thing in common—inflammation. Inflammation, noted by pain, heat, redness and swelling, is the body’s first defense against infection and injury. But when the flames of inflammation run out of control, deadly consequences arise. Celadrin, a blend of special fatty acids, is one of the most effective, natural anti-inflammatories. Both humans and animals have shown remarkable benefits of reduced pain and swelling, increased movement, and reduction of inflammatory factors when using Celadrin nutritional supplement.

Results of a double-blind, multi-centre, placebo-controlled trial (the most scientifically validated type) published in the prestigious Journal of Rheumatology found that Celadrin nutritional supplement when taken orally improved joint and mobility problems. Sixty-four participants between the ages of 37 to 77 were given Celadrin capsules. They were evaluated at the beginning, at 30 days and at the end of the 68-day study. Compared to the placebo, Celadrin shined. Participants had more flexibility, less aches and pain, and were able to walk longer distances than the placebo group.
