I declared myself a biochemistry/chemistry major in 2003 – right at the beginning of the Energy Drink Boom. Fascinated by these drinks and all the fears surrounding their use, I’ve applied my education (and basically all my free time) toward understanding the science behind energy drinks and their ingredients. In 2003, energy drinks contained synthetic caffeine as well as caffeine extracts from guarana and yerba mate. While synthetic caffeine was often criticized for being synthetic, guarana and yerba mate were often criticized for being “dangerous stimulants”. Then along came green coffee bean extract and coffeeberry/coffee fruit. As a caffeine consumer, you may be wondering, what is it about green coffee beans and coffeeberry that make it special? I encourage you to geek out with me over these game-changing energy drink ingredients.
