Hi Bill.

Concerning blood clots you might want to watch this. It will be 3/4 of the way through it till you see what I am talking about, but I'm not sure you will understand it without watching from the beginning. I can barely understand it (maybe), but this information would have been instrumental had we known it at the beginning of covid. This and a number of other things.

The topic concerns NAC and glutathion and breaking sulfur bonds in mucus and preventing clotting.

It is long and fairly technical but put forth in layman's type presentation by DrBeen.

Anyone still interested in treating covid might find it interesting also.

Edit: Disclaimer - I have had NAC around for more than a year and have taken some at various times. But I was going off of what was on the covid treatment web site (FLCCC.NET). This explains how it actually works (the biologic mechanism), which I did not know. Quercetin was one of the early part of covid treatment and NAC came later from other doctors use.
