NAC is a supplement that has been in some recommended protocols to protect against Covid—and there has been a very recent move to take it off the market:

IIRC I read somewhere that a pharma company is looking to reiintroduce it under patent.
I’m no biologist or medical professional, but as I understand it, there is some concern that at least the Pfizer and Moderna Covid shots can actually in a sense effectively “reprogram” DNA via a reverse transcriptase process: https://www.pnas.org/content/118/21/e2105968118.
And here is a patent describing how NAC, by increasing glutathione, can be used to block the reverse transcriptase process: https://patents.google.com/patent/US6566401B2/en.
This was described as a way of reducing AZT toxicity in treatment of HIV (and acetominophen overdose), but is there a chance that it will be used to minimize the damage from the Covid jabs at some point?
