N-Acetyl-L-Cysteine NAC

N-Acetyl-L-Cysteine(NAC) is a sulfur-containing amino acid derivative that serves as a precursor to cysteine and a substrate for glutathione synthesis. It plays critical physiological roles in the body, such as antioxidant, anti-inflammatory, and detoxification functions. In animal health and feed additive applications, NAC functions as a functional additive to alleviate stress responses, enhance immune function, and improve gut health. Additionally, it reduces the harmful effects of mycotoxins in feed, making it suitable for various livestock and aquatic species.

NAC promotes the synthesis of key antioxidant glutathione (GSH) in the body by supplementing cysteine precursors, directly enhancing intracellular antioxidant capacity; At the same time, it can directly eliminate free radicals, neutralize oxidative stress products, regulate the release of inflammatory factors, protect mitochondrial function, reduce the damage of free radicals and inflammation to cells, and achieve antioxidant, anti-inflammatory, and maintenance of cellular homeostasis effects.

The main sources of NAC (N-acetylcysteine) are chemical synthesis and biological fermentation. The content of NAC in natural foods is extremely low, and our NAC is derived from fermentation. The following is our flowchart.

NAC is an artificially synthesized substance that is almost absent from natural foods. Food only contains the precursor of NAC, cysteine, which can be converted into NAC in the body when consumed. Common foods rich in cysteine (which can synthesize NAC) include animal protein such as eggs and meat, dairy products, vegetables such as garlic, onions, broccoli, etc., beans and nuts such as chickpeas and soybeans.
