The original Red Bull [Krating Dang in Thai] is a syrupy drink from Thailand which comes in 100 to 150 ml. bottles, at 40 cents a bottle in Thailand, 69 cents each in the US if you buy it from a Chinese grocery in six packs. Red Bull used to, and probably still does, sponsor the Saturday morning Muay Thai matches on Thai TV. Red Bull was a rival to Lipovitan D, from Japan, and now has has other rivals Carabao Dang [”Red Buffalo”] and M-150.
I hear this stuff tastes like crap!
