Principal Proposed Uses
- Osteoarthritis (Relieving Symptoms and Possibly Slowing the Course of the Disease)
Glucosamine, most commonly used in the form glucosamine sulfate, is a simple molecule derived from glucose, the principal sugar found in blood. In glucosamine, one oxygen atom in glucose is replaced by a nitrogen atom. The chemical term for this modified form of glucose is amino sugar .
Glucosamine is produced naturally in the body, where it is a key building block for making cartilage.
There is no US Dietary Reference Intake for glucosamine. Your body makes all the glucosamine it needs from building blocks found in foods.
Glucosamine is not usually obtained directly from food. Glucosamine supplements are derived from chitin, a substance found in the shells of shrimp, lobsters, and crabs.
What Is the Scientific Evidence for Glucosamine?
Relieving Osteoarthritis Symptoms
Inconsistent evidence suggests that glucosamine supplements might relieve pain and other symptoms of osteoarthritis. Two types of studies have been performed, those that compared glucosamine against placebo and those that compared it against standard medications.
Slowing the Course of Osteoarthritis
Note: As with the positive studies of glucosamine for reducing symptoms, all of these studies were funded by a major glucosamine manufacturer.
