Frus - I've never used it so I looked up the nutritional info on the web. Assuming that what I found is the same as you're looking at, here's what I discovered:
Serving Size: 1/2 Cup (45g)
Servings Per Container: 12
Amount Per Serving:
Calories 150
Calories from Fat 15
Total Fat 1.5 g
Total Carbohydrate 21g
Dietary Fiber 2 g
Sugars 11g
Protein 17g
What would concern me are the 11g of sugar. That's 44 calories - about 30% - coming just from sugar. The first ingredient listed is the protein blend and then the second and third ingredients are added sugars.
If you're OK with that, then it's a decent amount of protein.
