Hey musclescience i have a quick question...i went to the doctors not to long ago to get some blood work done and when they called me back they said my blood protein level was to high and told me to stop taking protein shakes for a month and come back to get it checked out again to see if it had went back to normal....now my question is can this be caused from protein shakes?? i did some research and found out that food cannot cause a higher blood protein level and asked the doctor about it and he said that protein shakes are different and can cause this. But i have been drinking protein shakes for years and at most only ever have 1 a day post workout...the whole thing seems a little unclear to me and i was hoping you could clear this up for me?
