N-Acetyl Glucosamine

How does N-acetyl Glucosamine work?

N-acetyl glucosamine might help protect the lining of the stomach and intestines.

Are there safety concerns?

There isn't enough information available to know if N-acetyl glucosamine is safe. There is some concern that it might cause an allergic reaction in people sensitive to seafood.

Some preliminary research suggests that glucosamine might raise blood sugar in people with diabetes. However, more reliable research indicates that glucosamine does not seem to significantly affect blood sugar control in people with type 2 diabetes. Glucosamine with routine blood sugar monitoring appears to be safe for most people with diabetes.

There is some concern that glucosamine products might cause allergic reactions in people who are sensitive to shellfish. Glucosamine is produced from the shells of shrimp, lobster, and crabs. But allergic reactions in people with shellfish allergy are caused by the meat of shellfish, not the shell. There are no reports of allergic reactions to glucosamine in people who are allergic to shellfish. There is also some information that people with shellfish allergy can safely take glucosamine products.

Do not use N-acetyl glucosamine if:
  • You are pregnant or breast-feeding.
  • You are allergic to shellfish.
  • You have asthma.
  • You are scheduled for surgery in the next two weeks.
