N-Acetyl Glucosamine (NAG) differs from glucosamine sulfate in that it is attached to an acetic acid molecule, while glucosamine sulfate is attached to a sulfuric acid molecule. Although glucosamine sulfate is researched as being better absorbed than NAG, individuals sensitive to sulfur may tolerate NAG better and potentially derive more benefit from its use.* NAG is also well recognized for gastrointestinal support by enhancing mucosal integrity.*
