How NAC Works in the Body
-
Antioxidant Production
By promoting the production of glutathione, NAC serves as an indirect antioxidant, helping to protect cells from damage and reduce oxidative stress.
-
Supporting Detoxification
NAC plays an important role in the detoxification processes, particularly in the liver, helping to break down toxins and enhance your body’s ability to eliminate harmful compounds.
-
Balancing Cellular Health
NAC aids in maintaining healthy cells and tissues, allowing your body to function optimally. Whether it's supporting energy production, recovery from exercise, or general well-being, NAC keeps your cells in top condition.
Does NAC Really Work?
N-acetylcysteine (NAC) is a medicine widely used to treat paracetamol overdose and as a mucolytic compound. It has a well-established safety profile, and its toxicity is uncommon and dependent on the route of administration and high dosages. Its remarkable antioxidant and anti-inflammatory capacity is the biochemical basis used to treat several diseases related to oxidative stress and inflammation. The primary role of NAC as an antioxidant stems from its ability to increase the intracellular concentration of glutathione (GSH), which is the most crucial biothiol responsible for cellular redox imbalance. As an anti-inflammatory compound, NAC can reduce levels of tumor necrosis factor-alpha (TNF-α) and interleukins (IL-6 and IL-1β) by suppressing the activity of nuclear factor kappa B (NF-κB). Despite NAC’s relevant therapeutic potential, in several experimental studies, its effectiveness in clinical trials, addressing different pathological conditions, is still limited. Thus, the purpose of this chapter is to provide an overview of the medicinal effects and applications of NAC to human health based on current therapeutic evidence.
