N-Acetyl-L-Cysteine (NAC) is the acetylated form of L-Cysteine, which is a conditionally essential amino acid - one of only three sulfur-containing amino acids, the others being Taurine (which can be produced from L-Cysteine) and L-Methionine (from which L-cysteine can be produced in the body by a multi-step process).
