Query: big improvement over old version

This drink is a big improvement over the old version. It it much more tasty and doesn't have that chalky aftertaste. The thing I object to is that they're marketing these as a meal replacement, when in my opinion, it should be thought of as a supplement.I suggest adding a couple of spoons of protein powder to add to the nutrition and also to drink them after a workout.
