About this supplement

N-Acetyl-L-Glutamine is a modified, acetylated form of the amino acid L-glutamine. This chemical modification enhances its stability and bioavailability compared to free glutamine, as it is more resistant to degradation in the digestive tract and plasma. It serves as a more efficient precursor for raising plasma and tissue levels of glutamine, a conditionally essential amino acid critical for protein synthesis, immune function, gut health, and cellular energy production. The acetyl group is cleaved in the body, releasing L-glutamine. It is particularly valued in supplements for its superior absorption and reduced gastrointestinal side effects.
