Caffeine Effects on the Brain – Part 1

Welcome to GreenEyedGuide, your guide to the science behind caffeine and energy drinks. This is a series on How Caffeine Affects the Brain. Since this is a complex topic and we have a lot to cover, I’ve broken the key questions into different posts. In Part 1 we’ll discuss how caffeine makes you feel awake and alert, we’ll review the biochemistry (which you can skip), and we’ll summarize the ways caffeine does and does not help you focus.

Later in this series, we’ll also talk about:

  • Why does caffeine work differently after an all-nighter?
  • What ingredients in energy drinks help you focus during gaming?
  • Is coffee or energy drinks better for studying?
  • Does your brain get addicted to caffeine and energy drinks?

Part 1: How does caffeine help you focus?

Should you be afraid of this Monster Energy Drink? Science and Safety Behind Caffe Monster Energy Coffee

Monster Energy hit US markets in 2002 and helped establish the energy drink stereotype: “energy drinks are dangerous concoctions with high amounts of caffeine and sugar”. It’s hard to deny this stereotype is still applicable, however, there are a growing number of caffeinated beverages which don’t fit this mold. What happens when one of the energy drink companies responsible for the Energy Drink Boom comes out with one of these not-quite-an-energy-drink alternatives?

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. After 10+ years in this field, I believe parents have a right to be concerned about energy drinks, but that concern needs the right context to do anybody any good. How concerned should we be about the safety of Caffe Monster Energy Coffee?

When Does Coffee Become an Energy Drink? Science Behind Starbucks Doubleshot

As a biochemist who researches energy drinks, I get asked all the time why people need energy drinks and why people can’t just drink coffee instead. There’s no easy way to answer these questions, but it helps if we look at the products which blur the lines between “coffee” and “energy drink”. Read more

Science Behind Energy Drink Ingredient Interactions

A few people believe that caffeine-ingredient interactions are what make energy drinks inherently more dangerous than coffee. Using the ingredients in this drink’s “energy blend”, let’s review the research available on energy drink ingredient interactions. Read more
