It's got caffeine, taurine, ginseng, guarana, OK, I'm familiar with all that; but it's also got B vitamins in forms I've never heard of--cyanocobalamin and pyridoxine hydroxide. Also, I felt the zoom after 2 sips--and I'm *not* a lightweight. All that remains--carbonated water and natural flavor. Can any nutritional scientific-minded sorts tell me just how evil or innocuous this stuff is?

Same thing, different name. Generally not going to give you a buzz unless you're truly deficient. My money is on the caffeine (stimulant) + guarana (more stimulant) combo.
