My protien was low alot also.. I was told to drink Carnation Instant Breakfast. I did, it helped, my other numbers remained the same b/c I was on PD, otherwise my potassium/phosphorus may have went up. Since your husband is on home dialysis 6 days a week, I'm sure the protien bar will help his protien but not really effect his other numbers, if they did you could always cut down on some other things or whatever. Good luck.
