N-Acetyl-D-Glucosamine (NAG, GlcNAc) is a naturally-occuring compound found in human joints and cartilage. It is a secondary amide between glucosamine and acetic acid and is ubiquitous in animals, insects, crustaceans and bacteria, where it forms an integral part of the bacterial cell wall. It consists of an amino acid bound with a sugar-like compound and forms a structural matrix.
NAG is best known as a joint-support supplement for athletes or aging persons. It has been used in several studies exploring its potential to support healthy joints and bones. One essential role of NAG in the human body is to assist with the synthesis of cartilage, to cover and protect joints. It may also be useful for the synthesis of hyaluronic acid; a natural shock absorbent found in synovial fluid.
Research suggests that supplementing with NAG may help to protect and strengthen joints and to improve exercise-related inflammation. Further, it is believed by many to have immune-supporting properties.
