You should check with you NP to see what their requirements are for you. I had no problem with the Unjury unflavored, chocolate or vanilla. For 2 weeks post op, I was put on Isopure Drinks. They have 40gs of Protein each. I had 2 a day and 1 chicken buillon/broth with a scoop of the unflavored Unjury. I did this for 2 weeks. Once I was moved to the soft diet I stated drinking the Pure Protein shakes (usually 2 a day). And the Pure Protein Vanilla Protein Powder in greek yogurt, in order to get my protein in, depending on what I eat now too. I did try and found that the Unjury protein in water did not mix well, and they really don't recommend it to be used as such. I also have tried the EAS Myoplex Lite which has 20 gs of Protein in them. They taste pretty good to me too. Good luck!
