@ post 55. I have a similar regimen. (since I will not take any of the vaccines). I include NAC - have read much that it can help the body defend against covid. Oddly enough amzn took it down shortly after - but it is still widely available.
I saw NAC on amazon two days ago after someone recommended it, but it was pretty pricey - about $50+ dollars a bottle - so I didn’t order any yet.
Update: I just went back to amazon and couldn’t find NAC. My search also gave a result saying that the FDA had pressured amazon to stop selling NAC, and they agreed. So I ordered some from another company. What the heck is going on? Why are they making it so hard to get these supplements that may help fight Covid? Maybe we know the answer.
