What is N-acetyl Glucosamine?

N-acetyl glucosamine is a chemical that comes from the outer shells of shellfish.

Don't confuse N-acetyl glucosamine with other forms of glucosamine, such as glucosamine hydrochloride or glucosamine sulfate. They may not have the same effects.

Read glucosamine product labels carefully for their content. Most glucosamine products contain glucosamine sulfate or glucosamine hydrochloride. Although glucosamine sulfate and glucosamine hydrochloride are marketed together in combination products with N-acetyl glucosamine, there haven't been any human studies that have evaluated these combinations for treating osteoarthritis.

You may also see chitosan as an ingredient in some glucosamine products. Chitosan is a form of N-acetyl glucosamine that has been chemically altered.

N-acetyl glucosamine is taken for osteoarthritis and inflammatory bowel disease (IBD), including ulcerative colitis and Crohn's disease.

Insufficient Evidence to Rate Effectiveness for...

  • Inflammatory bowel diseases, including ulcerative colitis and Crohn's disease. There is some early evidence that N-acetyl glucosamine taken by mouth or rectally might decrease symptoms of IBD in children with Crohn's disease or ulcerative colitis.
  • Osteoarthritis.
  • Other conditions.
More evidence is needed to rate the effectiveness of N-acetyl glucosamine for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
