N-Acetyl Cysteine

N-Acetylcysteine (NAC) is a compound with several noteworthy uses and benefits as discussed by Andrew Huberman.

1. Precursor to Glutathione: NAC serves as a precursor to glutathione, which is the body's master antioxidant. This means it helps reduce reactive oxygen and nitrogen species, especially in cells under stress, such as during an infection 1.

2. Mucolytic Agent: NAC is known for its mucolytic properties, meaning it helps break down mucus. This can be particularly beneficial for conditions like cystic fibrosis and for relieving congestion during colds or flu 2.

3. Flu and Cold Prevention: Some studies suggest that NAC may reduce the risk of contracting influenza. In one study, 79% of the placebo group developed symptoms, compared to only 25% of those taking NAC. However, more research is needed to confirm these preventive benefits 3.

4. Availability and Dosage: NAC is generally available over the counter in the U.S., although its availability has been challenged due to regulatory actions. Suggested dosages for preventing colds and flus are about 600 mg twice a day, or higher doses during an active cold 4.

5. Alternative to Decongestants: Andrew Huberman prefers NAC over traditional decongestants, which can cause a rebound effect and other side effects. Instead, NAC effectively alleviates sinus pressure by promoting mucus flow 2.

Overall, NAC's ability to boost glutathione and act as a powerful mucolytic makes it a valuable supplement, particularly during cold and flu season. Always consult with a healthcare provider before starting any supplement regimen.
