N-Acetylcysteine (NAC) is an acetylated derivative of the amino acid L-cysteine and a critical precursor to glutathione, one of the body’s primary endogenous antioxidants. In Brazil, NAC is marketed primarily as a dietary supplement for immune and respiratory support, liver detoxification, and general cellular health. The product sits firmly within the consumer goods and FMCG domain, intersecting both branded and private-label categories.
