I think it would depend on the purpose. The breakdown does seem good for post-workout, as Sara wrote above.
However, I wouldn't take it, because it looks like a "carby" version of a multi-vitamin that gives some fiber and some protein, but not at the level of a protein supplement/shake (e.g., whey protein isolate or concentrate).
I prefer to use my carb calories on real food, for the most part, even post work-out. I'd rather have a banana, some kefir, a whey shake, etc.
You can definitely get the same other benefits in: food, a multi-vitamin, a fiber supplement (if your diet is falling short), and with more pure protein supplements. And this allows more precision in how you get those various micro or macronutrients.
If you're someone who likes drinking your calories and struggles to take in enough carbs or if you're someone who finds it hard to eat solid foods after exercise, then I can see how this would help.
