What is Acetylcysteine?
Acetylcysteine (also known as N-acetylcysteine/NAC) is a powerful antioxidant and mucolytic medication, highly recommended for respiratory health, liver support, and detoxification. Ranked as a leading respiratory supplement and liver detox medicine, acetylcysteine is used both as a prescription drug and as a supplement worldwide.
Key Uses of Acetylcysteine
- Treatment of acetaminophen (paracetamol) overdose (life-saving antidote, prevents liver damage)
- Mucolytic agent: Thins mucus secretions for easier breathing in conditions like chronic bronchitis, COPD, asthma, cystic fibrosis
- Antioxidant support: Replenishes glutathione levels, reducing oxidative stress
- Liver health: Supports natural liver detox and protects against toxins
- Immune support: Strengthens immune defense against infections and inflammation
- Mental health: Supports brain health and may benefit psychiatric disorders
Mechanism of Action
Acetylcysteine works by acting as a precursor to glutathione, the body's master antioxidant. It breaks down thick mucus and neutralizes harmful free radicals, protecting cells from oxidative stress. In acetaminophen overdose, acetylcysteine restores depleted glutathione in the liver, allowing safe breakdown and removal of toxic metabolites.
