Guns recommend this and it does work. My GFR was hovering around 50 or so. I take 4 Kidney Stuff, 2 morning and 2 mid day. It says to take more but I wanted to try it at the lower dose.
My GFR went from 50s to 80+ in a few weeks. I don't care that I will be on it the rest of my life. It is all natural and it works.

Thanks Guns
