N-acetyl Cystine

N-acetyl-L-cysteine (NAC) is the acetylated form of the amino acid L-cysteine, supplied by Nustras as a white crystalline powder for supplement and pharmaceutical applications. It is a precursor to glutathione, the body's key endogenous antioxidant, and is widely used in antioxidant, respiratory and liver-support formulations.

NAC is formulated into antioxidant and glutathione-support supplements, respiratory- and immune-health products, liver- and detox-support blends, and sports-nutrition products, in capsules, tablets and powders.

The material carries CAS 616-91-1, the molecular formula C5H9NO3S, and is a white crystalline powder with a characteristic odour, typically supplied to pharmacopoeial grade (for example USP/EP). Identity, assay, specific rotation, heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies NAC in bulk commercial quantities, in fibre drums or cartons, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. The regulatory status of NAC in dietary supplements varies by market; buyers are responsible for confirming the permitted use, grade and claim for their application and jurisdiction.
