45 All N-Acetyl-Cysteine (NAC) Products Have Now Been REMOVED From Amazon.com. NAC may protect you from "covid." FDA wanted to ban it last year. This could be a prelude to a ban. You might want to find some and buy it now before it's gone.

I take glutathione pills sometimes and I also notice a difference when I take it so it definitely has some usefullnedd as an oral supplement.
Another note about NAC, when you take it, make sure you take it with plenty of water. You don't want to develop kidney cysteine stones.
