My pulmonologist has NAC on his respiratory immunity supplement list like zinc, etc. I was unfamiliar with NAC until a few months ago. So far, no covid symptoms.<br /><br />NAC is listed among potential life-extension supplements planned for future in depth study. So far, I'm still kicking. It must be working—no negative metabolic side effects to report. The combination of NAC and TUDCA did a great job normalizing a couple of marginal liver panel test results.
