N-Acetylcysteine (NAC) is highlighted by for its potential benefits in preventing and treating colds and the flu. Specifically:

  1. Preventive and Treatment for Colds and Flus:

    • NAC has been shown to potentially prevent and treat colds and flus. In a study, only 25% of individuals taking NAC contracted influenza compared to 79% who did not take it. NAC works by increasing glutathione levels, a key antioxidative mechanism 1.
  2. Mucolytic Properties:

    • NAC serves as a mucolytic agent, helping to reduce mucus. This can be particularly useful in conditions like cystic fibrosis or common colds, where mucus buildup is a problem 2.
  3. Dosage and Use:

    • For prevention of cold, the typical dosage mentioned is about 1200 milligrams per day, divided into two doses. If treating a cold that's already developed, the dosage might increase to 900 milligrams taken three times per day 1.
  4. Over-the-Counter Availability:

    • As of the last update provided by Dr. Huberman, NAC was available over the counter in the United States. This availability might be influenced by regulatory changes, so it's wise to check the current status if considering its use 1.

This information is derived from the episode titled "How to Prevent & Treat Colds & Flu" where these aspects of NAC were discussed thoroughly by Dr. Huberman.
