N-acetylcysteine (NAC) is a potent antioxidant and precursor to glutathione that reduces inflammation, breaks down mucus, and supports detoxification. It is clinically used to treat acetaminophen overdose and chronic respiratory conditions like COPD. Other benefits include improving fertility, regulating blood sugar, and supporting mental health.
-
Boosts Glutathione & Antioxidants: NAC increases glutathione levels, the body's primary antioxidant, which combats oxidative stress and protects cells.
-
Respiratory Health: Acting as a mucolytic, it thins mucus and reduces inflammation, aiding treatment for bronchitis, COPD, and cystic fibrosis.
Detoxification: It is a standard treatment for acetaminophen (paracetamol) overdose to prevent liver and kidney damage.
Mental Health & Neurological Support: NAC helps regulate glutamate, a neurotransmitter, showing potential in treating schizophrenia, bipolar disorder, obsessive-compulsive disorder (OCD), and addiction.
Fertility Enhancement: NAC can improve fertility in men by reducing oxidative damage to sperm and in women with PCOS by aiding ovulation.
Immune System Support: Some evidence suggests it helps reduce the severity of viral infections like the flu.
