Red Bull Cola: Strong and Natural

It has always been the red bull gives you wings slogan all this while for me. However, I accidentally came across Red Bull Cola! Now Red Bull is coming out with their own cola. No, it's not gonna have the power to topple Pepsi, not to mention Coca-Cola, even though it's backed the bull. However, Red Bull is still sticking to its guns by printing. The question is, how does cola relate to strong? By adding "natural", it sounds like some sort of enhancer like viagra or ginseng. Weird.
