N-Acetyl-L-Cysteine (NAC) 500mg - 90 Capsules | Metagenics
Metagenics N-Acetyl-L-Cysteine (NAC) 500 mg is a food supplement providing N-acetyl-L-cysteine, a stable and highly bioavailable form of the amino acid L-cysteine. NAC is commonly used as a dietary source of cysteine, an amino acid required for the production of glutathione, an important antioxidant involved in cellular defence and detoxification processes in the body.
Glutathione plays a key role in neutralising free radicals and protecting cells from oxidative stress. Because L-cysteine is considered a rate-limiting amino acid in glutathione production, NAC supplementation is commonly used to help replenish glutathione levels and support antioxidant defence systems in the body.
NAC is also involved in the body’s natural detoxification pathways, particularly those associated with liver metabolism. It supports phase II detoxification processes by providing cysteine required for the formation of glutathione, which helps the body neutralise and eliminate metabolic by-products and environmental compounds.
In addition to its antioxidant role, NAC has been studied for its effects on respiratory health. It can help reduce the thickness of mucus in the respiratory tract and support normal lung function by loosening mucus and supporting immune defence in the airways.
Each capsule provides 500 mg of N-acetyl-L-cysteine. The product is supplied in capsule form for convenient daily supplementation and controlled dosing. The formulation contains NAC together with standard capsule and stabilising ingredients and is designed to provide a consistent and reliable source of this amino acid derivative.
