Premier Protein is the one recommended by our oncologist. It’s a good stop gap measure to keep protein levels up. If it’s too sweet (I find it is) you can add almond milk or oat milk, for example, just make sure you have the whole container. When in treatment the amount of protein needed is much higher than what is needed in a healthy diet. Try and find some high protein foods that you like or can tolerate and eat them as well. The drink can help but shouldn’t replace eating well. A good diet during treatment is a key element in being able to continue with treatment. Take anti nausea meds if necessary but make sure you do everything you can to eat.
