Side effects of Glucosamine


Data source: http://www.holistichealthtopics.com/HMG/Bvitamin.html

Glucosamine sulfate side effects are nothing compared to long term use of over the counter medications such as aspirin or ibuprofen. These drugs that we so commonly take for pain relief are not meant to be taken long term and can have serious side effects. In the New England Journal of Medicine it was reported that the drugs Advil, Motrin, Aleve, Ordis, Aspirin and twenty others cause 16,500 deaths and 103,000 hospitalizations per year. In contrast, glucosamine side effects do not cause any deaths or hospitalizations. It is safe to say glucosamine is safer to take than these drugs for osteoarthritis.

Because glucosamine is a carbohydrate, one of the glucosamine sulfate side effects may be a change in blood sugar levels. This is why it is important to talk to your doctor if you are a diabetic. You should test your blood sugar often if you are diabetic and taking glucosamine.

Some glucosamine sulfate side effects that can occur when glucosamine is used in very high doses (many times the daily dose) are nausea, diarrhea, soft stools and gastric fluctuations.

The most common glucosamine sulfate side effects are soft stools and intestinal gas. One potentially dangerous glucosamine side effect, which has been demonstrated in some animal studies, is the worsening of insulin resistance which may lead to diabetes. This glucosamine side effect has so far not been demonstrated in humans, however.

If you are taking blood thinning medications, you should talk to your doctor before taking glucosamine because it may cause the glucosamine side effects of bleeding and thinning of the blood.

Overall, glucosamine has been used safely for many years with few reported side effects. Studies have not shown any negative side effects in humans so far. Certain groups of people such as diabetics, those with allergies to shellfish, pregnant women, women who can become pregnant, children and those taking blood thinners should avoid glucosamine because of potential side effects or the lack of studies done on these groups.
