If you don’t have a renal dietitian you can talk with you need to ask your doctor how you can increase your protein intake. If your appetite is low and/or meat tastes funny, your peritoneal dialysis may not be working well enough. Toxins in the bloodstream can cause those symptoms. Also, PD removes a lot of protein that must be replaced through diet or the albumin level falls placing the patient at great risk of infection, hospitalization and even death! Studies have shown that albumin should be 4 or higher and these risks increase when albumin is less than 3.5 and are even higher as the albumin falls lower.
I hadn’t heard of the protein powder you’re using so I looked it up. Each 10 gram scoop provides 8 grams of soy protein and is only 36 calories. I gather that some people use this for weight reduction. It may not be the best protein supplement you can get. For comparison, in the U.S. some dialysis patients drink Boost, a protein drink. It has 15 grams of high quality protein. Here’s an article from AAKP, one of the patient organizations, that discusses protein supplements:

It is urgent that you do what you need to do to get improve your nutrition quickly!
