N-acetyl-L-cysteine (NAC) is a stabilized form of L-cysteine, an essential amino acid. During various life stages, such as aging, growth, or physical activity, the body may require increased amino acid intake. NAC is rapidly absorbed in the intestine and subsequently converted back into L-cysteine, a crucial sulfur source for the body.

L-cysteine serves as a building block for proteins and glutathione peptides. Glutathione, in turn, is a component of glutathione peroxidase, an enzyme that breaks down hydrogen peroxide. Biogena NAC 600 contains easily absorbable N-acetyl-L-cysteine, making it suitable for daily supplementation.
