==The benefits of Glucosamine are==
Glucosamine is often combined with chondroitin [[Chondroitin]] sulfate, a molecule naturally present in cartilage. Chondroitin gives cartilage elasticity and is believed to prevent the destruction of cartilage by enzymes. Glucosamine is sometimes combined with methylsulfonylmethane, or MSM, in nutritional supplements.
* Osteoarthritis. Most research on glucosamine sulfate has measured its effectiveness on osteoarthritis of the knee. However, there is some evidence that it might also help osteoarthritis of the hip or spine.
* Temporomandibular joint (TMJ) arthritis. TMJ is the joint in the jaw that dentists often check for clicking and proper alignment. It can be a factor related to jaw pain, chewing, yawning, and talking. Some research shows that taking glucosamine sulfate works about as well as the nonsteroidal anti-inflammatory drug (NSAID) ibuprofen (Motrin, Advil, etc) for relieving jaw pain. In some people, pain relief appears to continue for up to 90 days after glucosamine sulfate is discontinued.
