Use As A Dietary Supplement
Oral glucosamine is a dietary supplement and is not a pharmaceutical drug. It is illegal in the US to market any dietary supplement as a treatment for any disease or condition. Glucosamine is marketed to support the structure and function of joints and the marketing is targeted to people suffering from osteoarthritis. Commonly sold forms of glucosamine are glucosamine sulfate, glucosamine hydrochloride, and N-acetylglucosamine. Glucosamine is often sold in combination with other supplements such as chondroitin sulfate and methylsulfonylmethane. Of the three commonly available forms of glucosamine, only glucosamine sulfate is given a "likely effective" rating for treating osteoarthritis.

Famous quotes containing the word supplement:
“That life is really so tragic would least of all explain the origin of an art form—assuming that art is not merely imitation of the reality of nature but rather a metaphysical supplement of the reality of nature, placed beside it for its overcoming.”
—Friedrich Nietzsche (1844–1900)
