325: Can NAC hurt your gut health?

Masterjohn Q&A Files Episode 325

Question: Can NAC Hurt Gut Health When Used to Disrupt Biofilms?

Short Answer:
N-acetylcysteine or NAC can be used at a dose of 600 to 2,400 milligrams per day for 5-10 days to disrupt biofilms and make it easier for antimicrobials to kill bacteria. Animal studies suggest that acute doses up to 6 grams do not deplete mucus or cause ulceration, but that an acute dose of 17.5 grams can deplete mucus and cause ulcers within two hours. Human studies suggest that 10 grams per day can be used for 24 weeks with fewer than 1 in 6 people complaining of gastrointestinal side effects. Yet, chronic use of NAC will thin the mucus, disrupt the biofilms used by normal healthy microbiota, and possibly deliver excessive sulfur to certain components of the microbiome. Therefore, I would not use it except for specific, targeted reasons, and I would not use it at a dose higher than needed or for a duration longer than needed.
