This is a summer 2020 submission and fall 2020 publication (doesn’t make it wrong, just gives timing context).<p>I was recommended NAC supplements and some cursory research suggested that it probably wasn’t going to hurt so I bought them ($14 a bottle) as a readily available OTC supplement. FDA sent out some threatening communications in fall 2020 which suggested they’d contemplate prosecuting the sales of NAC as a supplement and it predictably got a lot harder to find. I’m still taking some of the first 500 pills I bought as it seems unlikely to be harmful. (I’m not claiming it works, just giving some background not in the NIH paper.)
Curious if anyone has any first hand experience taking daily NAC supplements for long periods of time? I’ve been looking into it, but there doesn’t seem to be much material out there on it
