Reducing inflammation, breaking down mucus build up and inhibiting the replication of virus cells make NAC a powerhouse antioxidant when it comes to fighting viruses and protecting the lungs.

 Research shows NAC helps with congestion, elimination, and inflammation in the lungs. In a randomized, double-blind, placebo-controlled clinical study, NAC was shown to improve outcomes with Acute Respiratory Distress Syndrome (ARDS) patients when compared to a control group.

And while there are no studies yet on NAC and the SARS CoV-2, Chinese hospitals are researching it for it viral infections.

NAC shortens the lifespan of the influenza virus and reduces the symptoms associated with the flu.

An Italian study published in European Respiratory Journal found that only 25% of people who took NAC and were injected with a flu virus developed flu symptoms compared with 79% who received a placebo.
