Vampires, for some reason or another, cannot create enough energy for themselves. So they get it from other sources. Sanguinarian--blood drinker--vampires, get their energy from blood. Not nescessarily protein; this is mostly foudn in meat but can be in other things. Blood is a slightly alkaline substance and, correct me if I'm ewrong, contains no protein. they drink it for ENERGY, like Psi vmapires may bdrain prana for ENERGY
