This stuff is a miracle. Great for the liver as well as keeping me healthy from the c virus. Took it as soon as I started feeling bad and was fine two days later, lots of good information out there.

I did a bunch of research on this when the fda threatened to ban it. I tested positive for COVID and used this, vitamin D, zinc, and Quercetin… that combo worked great for me. Good Stuff, I am trying to spread the word to others to get this while you still can!!
