Meal replacement question?

So I was thinking about getting some GNC Total lean powder mix, I used it as a meal replacement and as protein due to the fact that I am a vegetarian when I was doing my Army training. Now that I'm back to running about 3 times a week will it be good for my purposes?

As long as it's not whey right? If you are a vegetarian......just to let you know whey comes from cows
