N-Acetyl-D-Glucosamine (NAG)

N-Acetyl-D-Glucosamine, often shortened to NAG, is an amino sugar. It appears in some dietary supplements and is different from glucosamine salts commonly used in other supplement categories. Long chemical names are easy to confuse. NAG refers to a specific acetylated form of glucosamine. The finished-product label should identify the exact ingredient rather than relying on the broad word glucosamine. MPG lists N-Acetyl-D-Glucosamine as one of the five compounds in the current VeraCell FAQ. Read the amount per serving and keep ingredient research separate from finished-product claims.
