Glucosamine is a natural chemical compound found in the body. As a supplement, glucosamine is most often used to ease the joint pain caused by arthritis.
Why do people take glucosamine?
Glucosamine helps keep the cartilage in joints healthy. But natural glucosamine levels drop as people age. This can lead to gradual deterioration of the joint.
There's some evidence that glucosamine sulfate supplements can help counteract this effect, although experts aren’t sure exactly how they work. Specifically, glucosamine has been shown to help ease the pain of mild to moderate osteoarthritis of the knee. Glucosamine may also help with other joint pain caused by osteoarthritis. However, the scientific evidence of glucosamine's benefit to other joints is not quite as solid.
Glucosamine has also been used for rheumatoid arthritis and other conditions, such as inflammatory bowel disease, asthma, allergies, chronic venous insufficiency, sports injuries, temporomandibular joint problems (TMJ), chronic low back pain, and many others. So far, these uses of glucosamine are not well supported by evidence from research studies.
How much glucosamine should you take?
For osteoarthritis, the typical dose of glucosamine is 500 milligrams of glucosamine sulfate taken three times a day. Some experts recommend taking glucosamine with meals to prevent stomach upset.
Can you get glucosamine naturally from foods?
Although glucosamine sulfate supplements are often manufactured from the outer shells of shellfish, there aren't any natural food sources of glucosamine.
What are the risks of taking glucosamine?
Side effects from glucosamine are generally mild. Studies have found that the side effects from standard doses of glucosamine aren't different from those of a placebo. At higher doses, side effects may be more likely from glucosamine. Side effects include upset stomach, heartburn, drowsiness, and headache. The level of glucosamine that would cause an overdose is unknown. On the whole, glucosamine seems to be a fairly safe supplement.
Risks. People with allergies to shellfish should be wary of using glucosamine, since it could cause an allergic reaction. Those who have diabetes, kidney disease, heart disease, bleeding disorders, or high blood pressure should check with a doctor before using glucosamine.
Interactions. People taking heart medicines, insulin, blood thinners, and diuretics should check with their doctors before taking glucosamine.
Given the lack of evidence about its safety, glucosamine is not recommended for children or for women who are pregnant or breastfeeding.
