Bolthouse Farms Perfect Protein Mocha Cappuccino.
This is a drink that has a little bit of substance do it. It contains coffee, milk and whey protein to give you that early morning jolt of caffeine and something in your stomach to fuel your workout. Before a morning run, I usually only take a few sips. Three gulps and I am ready to go. That tides me over for the duration of my workout. Sometimes I may drink again post workout, or I may have breakfast instead. I usually only have one or the other so as not to go overboard on my calorie intake.
Bolthouse Farms makes several products of this sort, so if coffee is not your thing, they have many fruit and vegetable blends to suit your tastes. They come in different sizes, so make sure to read the amount that consists of a serving. You can find it at all grocery stores (Kroger, Publix, Wal-mart, Target, etc.) in the refrigerated fruit section. You can also find Naked brand drinks, which are just another brand of the same type thing. I trust the ingredients in both of these brands, and I'm sure there are more out there. Just make sure to read the labels when choosing something like this so you get the nutrients, protein and vitamins you want.
