NAC - N-acetylcysteine is a precursor of the antioxidant glutathione, and has been used to loosen thick mucus in the lungs and treat acetaminophen overdose for decades. However, NAC can also boost the immune system, suppress viral replication, and reduce inflammation. Despite these valuable features, NAC has been mostly overlooked throughout SARS-Cov and MERS-Cov epidemics, as well as the current COVID-19 pandemic.
NAC is an immediate precursor to a very precious substance that our body makes. It's called glutathione. Amino acids such as cysteine, glutamate, and glycine are also natural precursors from the food we eat.
In the hospital, it is used in the intravenous and oral form to protect and restore the body before and after it has been exposed to certain chemicals, including radioactive dyes used to illuminate parts of the body during an MRI, and in the case of acetaminophen overdose. It’s also used sometimes to help cancer patients overcome the adverse events that may be associated with radiation and chemicals used in treatment.
