Research Recap: How do caffeine and taurine affect the heart muscle (myocardium)?

One of the biggest questions surrounding energy drinks is whether they are more dangerous for the heart than caffeine from coffee. Some people worry it’s the combination of ingredients, not just the caffeine content itself, which makes energy drinks more dangerous. As a biochemist studying energy drinks, I strive to better understand this risk by reviewing the latest research on caffeine and energy drink ingredients. In this Research Recap, we’ll review an experiment on how caffeine and taurine affect the contraction behavior of the heart muscle. Read more

Science Behind Rockstar Pure Zero and 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

Bai Sparkling, Cocaine Energy, and Monster Ultra Violet: July Recap of Quick Reviews – Science of Energy Drinks

Here’s a recap of the quick reviews posted this month for the “Science of Energy Drinks” series on the GreenEyedGuide Instagram and Facebook pages: Bai Sparkling Antioxidant Infusion, Cocaine Energy, and Monster Ultra Violet.

Bai Sparkling Antioxidant Infusion


The Science Behind BAI Sparkling Antioxidant Infusion: A healthy (weak) energy drink! I LOVE how they have the caffeine content, not JUST the “like a cup of green tea”, which can be ambiguous/misleading for some consumers. (not all green tea has the same content).

I also LOVE the stated amount of polyphenol antioxidants. I did my master’s thesis on polyphenols and THE MORE YOU CAN CONSUME, THE BETTER! (Note: Benefits are generic, like reduced risk of cancer)

Finally, the caffeine comes from COFFEE FRUIT EXTRACT. Not coffee beans, the whole fruit/pulp surrounding the coffee bean. DYK this fruit pulp USED TO BE considered food waste until one day someone realized a way to extract valuable nutrients from it?

In terms of caffeine content, this is WEAK SAUCE! One step up from plain water, #FatigueLevel2. It’s HALF a RED BULL but hey, that might be EXACTLY what you need sometimes, just a lil’ boost from a “clean” and natural source.

NATURAL sweeteners (stevia & erythritol), NATURAL flavors (plus the lil’ bit of juice), NATURAL color (but it’s in a dark can so not sure why there needs to be any color). NATURAL(ly occurring) preservatives and acidulants (acidity controllers) malic acid, citric acid, sodium citrate.

Cocaine Energy Drink

These pictures were sent to me to review. Not wild about the name of the drink but it’s not the worst energy drink I’ve come across.
✔280mg Caffeine per container is MORE THAN a can of ROCKSTAR and MORE THAN the 200mg limit per occasion recommended by the EFSA and other regulatory bodies. 👎 At least it is LESS THAN the 400mg caffeine/day limit 👍
✔18mg sugar is not great but it is LESS THAN the 36g limit and 25g limit for added sugars for men and women, respectively, from the American Heart Association
✔Sodium benzoate is used as a preservative that fights yeast and mold in acidic beverages (pH<4). Not sure where the “damages cells” fear-mongering comes from. Adults can eat 5mg PER KG OF BODYWEIGHT of sodium benzoate and be fine. [See my “Panera KNOW-No List for more: http://bit.ly/2hcPw23 ]
