Go Girl is one of the latest energy drinks hitting the market. It's marketed as "Beautiful Energy", to those girls who need a little extra "go".
Looking at its line up of active ingredients, it derives its energy boost from the B vitamins, along with a caffeine content similar to a cup of coffee.
Interestingly, the makers of Go Girl claim that many of its users enjoy it with vodka and other "fun mixers". But because their product is "a functional drink that enhances the body and mind", they recommend it for hangovers.
