NAC supplement

(NAC) supplements have shown significant potential in preventing and treating illnesses like influenza. A study mentioned by Andrew Huberman indicates that approximately 80% of people in a placebo group developed flu symptoms, while only 25% of those taking NAC did. NAC's primary mechanism is boosting glutathione, which is generally beneficial for health 1.

NAC is available over-the-counter in the U.S., though there have been discussions about its regulation. Some supplement companies previously made claims about NAC's efficacy in treating hangovers, leading to FDA intervention. However, due to advocacy, NAC remains accessible 1. Users can take 1200 mg daily, divided into two doses, or 900 mg three times a day for acute use, avoiding close to sleep to prevent discomfort 1.

Overall, NAC appears useful in immune support, alongside other supplements like zinc and vitamin D, though individual decisions should be based on personal preferences and available evidence 1.
