proteinex 18
I don't have any experience with this protein, I use UnJury, but I found this on www.cwimedical.com:
Proteinex 18 will supply patients that have low albumin levels the required amount of protein needed in their daily diet. With only 2 tablespoons administered to the patient, he/she will receive 18 grams of predigested protein in only 72 calories. It can also be easily mixed with any beverage the patient may choose and with foods such as apple sauce or Jell-O. Proteinex 18 comes in two new flavors black cherry and lemon lime. Proteinex 18 has maximized the effective dose without increasing volume.
So it looks like you can mix it with whatever you want. Hope this helps!
