More natural alternative to "Ensure"?
Background info: I have taken up running in the morning, and I like to go pretty soon after I wake up. But, my blood sugar is so low in the morning most of the time that I feel really groggy, dizzy and basically unable to preform unless I have something in my stomach. The reason I have been using ensure is that it is high in protein (which is very important to me for various reasons (flexitarian diet, trying to build muscle, trying to grow my hair out, etc.)) and easy to digest carbs which means when I am running it's not bouncing around in my stomach and giving me an ache. I also liked it better than other products because of the taste, texture and because it has a lot of vitamins and minerals which some other products don't have.
I am not necessarily looking for a specific brand, though I am not opposed to that, because I do enjoy making my own alternatives to a lot of these kinds of things. I am pretty proficient at making smoothies and similar things, and the thought has occurred to me, I am just at a loss of what exactly to put in it if I do make it myself.
So, basically what I am asking is does anyone know of a way I can make or buy some kind of liquid, easy to digest, high protein, high carb runners breakfast shake?
