    But it's not in the list of options. " protein, vitamin,carbohydrate and mineral."

    What do you mean by "cheapest"? Easiest for the body to use or cheapest at the grocery or health food/supplements store?


    Please clarify "cheapest" and thank you for the choices.  I was thinking "caffeine" until I read the whole question.
