Hello out there. My dad has a J-tube and is on Jevity 1.2 by Ross Nutrition. His doctor thought he might benefit from more protein in his diet. We had been thinking of giving him kefir (pasteurized milk with active probiotic cultures) through the tube as a supplement. We also thought of giving him vitamin D drops. But before we do anything so "wild and crazy," we want to check if anyone out there has experience with the kind of home-nutrition that can be given through a J-tube (I know there is more flexibility with a G tube). Any suggestions as to what might work well and what to avoid?
