NAC, 600 mg, 250 Capsules

NOW Foods NAC is a dietary supplement centered on N-acetyl-L-cysteine, a stable acetylated form of the amino acid cysteine. Cysteine is a rate-limiting precursor for synthesis of glutathione, a major intracellular antioxidant. NAC can supply cysteine after deacetylation and also contains a reactive thiol group, which explains its biochemical role in redox chemistry. As a supplement, NAC is commonly used for antioxidant and general wellness support. Its sulfur chemistry can produce a characteristic odor that does not necessarily indicate spoilage. Research on NAC spans many contexts, but routine supplement use should be described in terms of nutrient precursor and antioxidant biology rather than disease-treatment claims. From a nutrition perspective, the value of this type of supplement is its ability to provide a measured, repeatable amount of the target nutrient or bioactive compound when food intake, lifestyle, or individual needs make consistent intake difficult. Evidence for nutritional support depends on baseline status, diet, dose, and individual factors; this product is intended to complement, not replace, a balanced diet.
