What kind of protein powder for feeding tube?

I'm being revised from distal RNY to DS in two weeks and will have a feeding tube for a while. Opinions on the best protein powder to throw into the tube? Flavor doesn't matter. TIA.

You will get more replies to this on the DS forum. Did your doctor tell you that you would be using it? Sometimes a feeding tube is place in case there are problems after surgery and used to prevent dehydration. 

I went sent home with some from the hospital.  I also got several sample packets from my doctor.  Basically, anything works in the feeding tube.
