Every year Americans spend at least $50 billion on treating their low back pain and it's one of the leading reasons why people miss work. Glucosamine is a natural compound that is found in healthy cartilage and is commonly used to help with low back and knee pain.

So if you take glucosamine for back pain, what should you do?

Dr. Scott D. Boden, director of the Emory Orthopaedics & Spine Center, says he may still recommend trying glucosamine for a six-month trial to those patients who are interested in trying it. He says it's not surprising that glucosamine is not effective for all types of low back pain, but he suggests "there may certain subgroups of low back pain sufferers who may be responsive to the drug."

There are other ways to ease the pain if you are one of the 25 percent of Americans who experience at least one day of back pain every month. Exercises including yoga and pilates, massage therapy, and medications such as cortisone injections are just a few of the options to help relieve low back pain.
