NAC flu


N-Acetylcysteine (NAC) has shown potential benefits in preventing and treating colds and flu. discusses a study where NAC was found to significantly reduce the incidence of clinically apparent disease in subjects exposed to the H1N1 influenza virus. Only 25% of the subjects taking NAC contracted the flu compared to 79% in the control group. The primary mechanism attributed to NAC’s effectiveness is its ability to increase levels of glutathione, which is beneficial for health 1.

NAC is available over the counter in the U.S., and the suggested dosage for prevention is about 1200 milligrams per day, divided into two dosages of 600 milligrams each. For treatment, once symptoms of a cold are present, the dosage might be adjusted to 900 milligrams three times per day. It's important not to take it close to sleep, as it can disrupt sleep by increasing mucus flow 1.

Additionally, NAC serves as a mucolytic, helping to reduce the viscosity of mucus, which can alleviate symptoms of congestion 2. Although more randomized control trials are needed to conclusively establish its efficacy, these findings suggest that NAC could be a beneficial supplement for reducing flu symptoms and preventing infection.
