Short Bio

Much like a superhero, Danielle (aka GreenEyedGuide) lives a double-life. By day she works in R&D for a major fitness/supplement company; by night she is the energy drink expert and author of “Are You a Monster or a Rock Star: A Guide to Energy Drinks—How They Work, Why They Work, How to Use Them Safely”. Danielle earned her bachelor’s degree in Biochemistry from UC San Diego, and her master’s degree in Food Science from UC Davis. As the Quality Systems Manager for Beachbody R&D, she manages implementation, user training and front-end maintenance of systems including SharePoint (her favorite system), P4P, and Oracle Agile PLM. She loves puns almost as much as she loves talking about the food science behind energy drinks. When she’s not contributing to, running, training for her next Figure bodybuilding competition, playing with her bulldog, or working toward her Project Management Professional certification, she’s thinking of new ways to bust consumer misconceptions and chemophobia.

My Story

Like Paracelsus, the “Father of Toxicology”, I believe that the dose distinguishes a poison from a cure. Sugar isn’t going to kill you, but too much sugar might. Same thing with caffeine; same thing with water. I do not believe that all natural foods are automatically healthy, nor do I believe that all processed foods are automatically unhealthy. Case in point: some plants are toxic; vegetables that are washed, cut, canned and/or frozen are all technically processed food.

The details matter – that’s where I come in.

I earned my bachelor’s degree in biochemistry from the University of California San Diego and a master’s degree in food science and food biochemistry from the University of California Davis. I grew up without energy drinks and without coffee shops on every corner.

I hated the bitter taste of coffee and tea and learned to live without soda thanks to those years of wearing braces. In short, I learned how to make due without caffeine. And yet, I could not have balanced two part-time jobs as a full-time biochemistry major without the help of energy drinks.

When Monster Energy hit US markets, I had just started my advanced studies in nutrition and biochemistry. I heard the hype, I read the news stories about kids having energy drinks for breakfast, and I knew how and why energy drinks worked thanks to my college courses. I was immediately fascinated by these caffeinated products, and that’s when the dream to share my insight with others began.

My primary goal, right from the beginning, was to help people understand these products like I do, so they could make informed decisions to skip them or sip them safely.

Energy drinks are not for everyone, but it is folly to assume that no one can benefit from them. For one thing, there are far too many products marketed as “energy drinks” to assume they are all good or all bad.

About the Energy Drink Guide

Since 2003, I’ve collected research on energy drinks and supplements, while also collecting and assessing hundreds of energy drink products from New Zealand, Mexico, Germany, the United States and the United Kingdom.

In my book ARE YOU A MONSTER OR A ROCK STAR: a guide to energy drinks, I review 20 of the most common ingredients used in energy drinks. From the B-vitamins to yerba mate, this book explains what the ingredient is, what it does in the body and how much is too much (or too little in the case of vitamin deficiencies). Instead of using confusing science jargon or overly generic terms like everybody else, I use clever anecdotes and examples that anyone (not just science-nerds) can relate to. Want an easy way to understand how B-vitamins work? Niacin is like the person everyone wants at their party and vitamin B5, also called pantothenic acid, is like a dog on a leash. Read one vitamin section in this guide and you’ll never forget that vitamin’s role again.

In this book, I also review the ABC’s of caffeine safety: Adverse Event Reporting, Biological Sensitivity, and Consumption Specifics. Did you know that how fast someone consumes caffeine can alter its efficacy? Did you know that a carbonated energy drink can feel more potent than a non-carbonated energy drink with the same caffeine content?

I share these tips and tricks through my blog and my book, in the hopes of helping people see past the confusion and find what works for them.

I hope you enjoy looking at food science and caffeine through my green eyes.

    1. I like to start by reviewing paperwork before I actually taste any samples. If you would like to submit a product for review you can visit the “About” page on and use the submission form at the bottom. I love looking at different products and labels, thank you.
