Best of the best
you're bound to get 100 different answers regarding protein powders. People's tastes are really different. My two favorite brands are Syntrax and Unjury. You might want to pick up some sample packets of different protein powders to find some you like - then you won't end up buying a huge tub of something you hate.
I can't tell you the "best", only what I use and enjoy. My dietician recommended Premier Protein shakes. They come in little juice boxes. The recommendation could have been because of availability in my region as well as the nutritional contents.
It has 30g of protein per shake, 5g carbs, 3g fat. The dietician wanted me on less than 6g carbs and less than 4g fat per shake, so these worked out.
I'm taking the Opurity multivitamin in the morning and their calcium citrate for lunch and dinner (I'm 3 days post-op). The dietician said she's going to ask me to add b12 later, but not for now. Iron also comes later. They said they'll let me know.
Getting water down has been relatively easy for me. I take small sips and can get down about 500ml in an hour. I need 2L a day, whi*****ludes my protein shakes.
In the hospital, the first night, I was given 30ml cups and a glass of water. I was to drink 30ml ever 20 minutes. No issues there.
The next morning, they gave me half and half water and apple juice. Same 30ml ever 20 minutes, then they took my blood. I think the apple juice was for measuring my blood sugar levels. Not really sure.
At home, I just use apple juice to get my crushed meds down, but otherwise I'm on protein shakes and water right now.
For the water, I don't do the 30 ml thing. I just sip at it like the dietician told me to do. I stop if I feel discomfort, wait a bit, then continue.
