I've been instructed by a clinic I go to to get more protein in me. I have liver & kidney disease that is eating up the proteins in my body. Lost 35 lbs in less that 2 months. I am being treated but it's been a long road so far...I've been drinking the Ensure shakes but they have a lot of sugar, salt & potassium in them....So i'm looking for a powder that might not have the sugar, salt & potassium.....To be honest I don't really know what I'm looking for...
