See picture! so I went home on Easter Sunday and thought Premier Protein 1 gram of sugar , 160 calories, 30 protein fit all the requirements, although it did some requirements not all of them so with this surgery you must follow to the letter. the only one true protein shake that I needed was Ensure Max Protein Shake this is considered a clear protein shake and I have been able to tolerate it. the other one I poured a 1 ounce cup and sipped less than 1/4 of it and immediately my stomach did not tolerate it, kept coming back up my throat. so I hope this helps you guys when you are post OP, remember all protein shakes are not created equal.
