N-Acetyl-Glucosamine Vitamin

What is N-Acetyl-Glucosamine?

N-acetyl-glucosamine (NAG) is a form of glucosamine, one of the building blocks of joint tissue and other connective tissues. NAG differs from glucosamine sulfate and glucosamine hydrochloride; instead of a sulfur or chloride molecule, NAG has a larger, more complex molecule attached to it. As a result, NAG is an entirely different molecule than either glucosamine sulfate or hydrochloride, and it also appears to be handled by the body differently.
