Cool Blue Revitalizer, Red Bull Purple Edition, Iconic Protein Coffee Drink, Monster Hydro Mean Green, F’Real Frappe Coffee, and West Coast Chill: June 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: Cool Blue Revitalizer, Red Bull (sugarfree) Purple Edition, Iconic Protein Coffee Drink, Monster Hydro Mean “Green” (more like yellow), F’Real Frappe Coffee, and West Coast Chill (caffeine free!) energy drink.

Cool Blue Revitalizer

  • Caffeine Content 100 mg = Fatigue Level 2

Science Behind Cool Blue Revitalizer

Science Behind Cool Blue Revitalizer: This drink makes a big deal about 3 natural ingredients but it’s UNNATURALLY blue.

✔1. “Real Sugar” – true, but it ALSO has sucralose.
✔2. “Natural Flavor” – I guess BLUE drink =BLUE-berries? To me this drink tasted like CITRIC ACID OVERLOAD!!! WOAH BUDDY!
✔3. “Natural Caffeine” – From where? The label doesn’t specify but it’s 100 mg caffeine [#fatiguelevel2]
🤓PET PEEVE: 1 container= 1.3 Servings? Really…you couldn’t change your formula or can size?
🔬SODIUM BENZOATE— Did you know that benzoate salts like this one prevents growth of microorganisms like yeast and mold; it’s used for preservation of sour food (pH 4 and lower) and is often used with other preservatives especially at low pH (acidic food).
🔬SODIUM BENZOATE SAFETY NOTES — Consumers can ingest up to 5mg per kg of body weight of benzoic acid and its salts according to European Commission – Scientific Committee on Food. There are safety concerns suspected but unconfirmed for benzene formation from benzoic acid with ascorbic acid. However, this risk “cannot be reliably assessed on basis of data available” per BfR Expert Opinion. [More Info on the “Panera KNOW-No List“]

Red Bull Purple Edition (sugarfree)

  • Caffeine Content 114 mg = Fatigue Level 3

Science Behind Red Bull Purple Sugar Free

The Science Behind RED BULL PURPLE EDITION: Red Bull has less caffeine and fewer ingredients than Monster and Rockstar. No guarana, carnitine, glucuronolactone, ginseng, or ginkgo; NO PRESERVATIVES! NO SUGAR!

🤓Since Red Bull has been around a long time there are mounting scientific studies testing its effectiveness
🤓Red Bull is not only the NUMBER ONE SELLING ENERGY DRINK BRAND  on the PLANET, they also set the standard for energy drink industry SAFETY GUIDELINES. Red Bull was the FIRST ENERGY DRINK Company to list caffeine content on their cans several years ago, paving the way for other companies to follow suit.
🤓FURTHERMORE Red Bull has been open about their commitment to food safety and quality – you can read all about that HERE: ⚡ Red Bull on Caffeine Safety and Transparency
✔This MAY NOT BE FOR YOU IF you are trying to avoid artificial flavors and/or sweeteners – This drink has Sucralose and Ace-K but I am more concerned about the KNOWN effects of high sugar intake than the DEBATABLE effects of these two sweeteners.
✔Ace-K has been USED AROUND THE WORLD for 15 years and used in the US since 1988.
✔Sucralose was approved by FDA in 1998, and it’s considered safe by government/regulatory agencies worldwide.
✔As far as caffeine interactions that (maybe?) make energy drink more dangerous than coffee, I enjoy Red Bull’s simple ingredients, sugarfree options, and moderate caffeine content. 🤓💚⚡⛾⚡🔬⚡

Iconic Protein + Coffee Drink

  • Caffeine Content 180 mg = Fatigue Level 3

Science Behind Iconic Protein Caffeine drink

If caffeine is best for PREworkout and protein is best for POSTworkout, what do you do with a CAFFEINE+PROTEIN COMBO?
🤓 DRINK IT!
But seriously, here’s what you should know:

✔ This drink has 180 mg caffeine per container. That’s as much as a Monster Energy (160 mg)
✔Caffeine doses of 3-6 mg caffeine per kg bodyweight are the best for pre-workout. That’s the range used in “[X] Til Exhaustion” studies (cycling, running, rowing…)
✔ Protein doses of 20-25 grams* protein taken in the 30 min window after workout is ideal for muscle growth but overall protein consumption matters too. *NOTE bigger protein doses don’t mean bigger results
✔ONLY 3 GRAMS SUGAR from Agave. Sweetness also comes from MONK FRUIT (aka Luo Han Guo) & STEVIA! I LOVE seeing these natural sweeteners used in caffeinated beverages 🤓💚🔬➕⛾➕🏋️‍♀️

Monster Hydro Mean Green

  • Caffeine Content 125 mg = Fatigue Level 3

Science Behind Monster Hydro

As the GREENEyedGuide I’m bummed “Mean GREEN” is yellow.

As a Food Scientist, I know artificial green is hard to keep green and natural green often involves spirulina, which has the slightest seawater taste. I don’t normally talk about taste in my reviews bc it’s subjective, but this tasted like flat Moutain Dew or old lemonade to me. 🤓💚🔬⛾

KEY Ingredients:
✔Sugar sources include sucrose (table sugar), glucose, and artificial sweetener sucralose. 23g! Not awful but <10g is my sweet spot (food pun!)
✔NO GUARANA OR TAURINE OR CARNITINE so really different than the typical Monster Energy Blend.
125 mg caffeine per bottle, compared to 180mg in most flavors of Monster Energy.

Is Monster Hydro a healthier alternative to Monster Energy?
YES in terms of lower caffeine content and FEWER Caffeine-(other ingredient) INTERACTIONS, which some people* think make some energy drinks more dangerous than coffee.
*I’m on the fence about this. Caffeine-Taurine-glucuronolactone combos are fine but no data for or against caffeine-carnitine combos yet.

F’real Frappe Coffee

  • Caffeine Content not disclosed – Unknown Level of Fatigue

Science Behind FReal Frappe Coffee

That Moment When you want to hide your CAFFEINE CONTENT so badly, you COMPARE yourself to something AMBIGUOUS. “2x caffeine as leading frozen coffee” 

Who is the leading FROZEN coffee and HOW MUCH caffeine do they have? It is FALSE to assume a cup of coffee has a standard amount. 1 cup at Starbucks doesn’t equal 1 cup at Pikes or 1 cup at your hotel.
Neat concept with the DIY F’Real Blender machine but if we’re going to GET REAL (or “f’real”) ABOUT CAFFEINE SAFETY we need EVERYONE to report caffeine content.

Have you ever seen a bottle of ALCOHOL that DID NOT disclose the %?
PS – sixty-one grams of sugar y’all. Sixty. One. But look at how clean and simple the ingredients are. Too bad simple doesn’t = healthy. 🤓💚⛾🔬

West Coast Chill (caffeine free energy drink)

  • Caffeine Content = ZERO! Fatigue Level 0-1 Energy Drink

Science Behind West Coast Chill

An energy drink with NO CAFFEINE?!? Does the term “energy drink” mean anything anymore!?!

Let’s inspect it: 🤓💚⛾🔬Active ingredients include:
🤓Ribose – a compound that participates in an odd (pun) energy producing reaction called the Pentose phosphate pathway. Promising science, just hasn’t caught on yet.
🤓Ginseng – be skeptical of benefits!
🤓Arginine – amino acid with important jobs in the body (Urea Cycle Waste Removal). HOWEVER the BEST way to supplement arginine is to TAKE Citrulline!
🤓B-vitamins AND minerals – minerals aren’t usually in energy drinks. Curious… 🤓💚🔬⛾📚

Science Behind Guru Organic Energy

Energy drinks have come a long way since 2003 when all energy drinks looked like Red Bull or Monster. GURU Organic Energy drink is more proof of that. GURU is not your stereotypical energy drink, and in this post, I’ll review the key ingredients, the caffeine content, and if it’s a good idea to drink this every day.

What is “Organic Energy”?

Ask a science nerd like me about “Organic Energy,” and you’ll get a lot of puns.  There’s “organic energy,” as in energy that’s inherent or innate. Then, there’s “Organic” as in “based on the study of carbon-based molecules.” But what about carbon-ated drinks? 

  All puns aside (sorry, not sorry), let’s talk about a carbonated energy drink that is certified-Organic.

The Energy Drink of the Month for June 2017 is GURU Organic Energy.

Science Behind Hiball Energy Coffee

Succeeding in the energy drink market can be both challenging and liberating: while it’s challenging for a brand to overcome negative perceptions associated with energy drinks, there’s freedom and possibility in developing a novel energy blend with a unique flavor and sweetness profile. However, in developing an energy drink that more closely resembles coffee than soda, there are a whole new set of challenges. People can be rather particular about how their coffee tastes, and a quick glance at a coffee flavor wheel demonstrates the multitude of different flavor characteristics available. How do you develop a product that pleases both energy drink consumers and coffee drinkers alike? Read more

Science Behind Celsius Energy

Based on recalls, litigation, adverse event reports, and consumer complaints, some of the riskiest product categories are energy drinks, weight-loss supplements and sexual health products. If you thought energy drinks got a lot of scrutiny in the press and by politicians, just image the pressure for a product that is both an energy drink and a weight loss supplement.  For those on quests to become more informed consumers, examining such a product is a wonderful, often enlightening exercise.  Moreover, May is the perfect month to examine such a product for two reasons: students are more likely to try new caffeinated products as they try to cram for finals; and figure-conscious individuals may be more likely to try a product they believe will help them reclaim their beach-ready body for summer. A product that is both an energy drink and a weight-loss product fulfills both types of curiosity.

The Energy Drink of the Month for May 2015 is Celsius Raspberry Acai Green Tea.

THREE-SIXTY DEGREES CELSIUS — Honest Product Review from Food Scientist, Gym Rat, Caffeine Aficionado

FIVE POINTS OF PRAISE

  1. One whole can is one whole serving. That makes it easier to understand EXACTLY what you’re getting and how much of it. No Portion-Distortion here.
  2. Though caffeine is part of the “Meta-Plus Proprietary Blend”, the amount of total caffeine IS stated on the can. One serving is one can, which offers 200 mg caffeine. This amount of caffeine is the maximum amount recognized safe as a single dose, according to European Food Safety Authority’s Scientific Opinion on Caffeine Safety. According to this study, 200mg doses don’t raise safety concerns even when consumed less than two hours before intense exercise.
    ***Note that healthy adults can have up to 400mg caffeine per day, and also please note it is never recommended to “chug” your energy drink [See Duh-Alert: AHA says chugging caffeine is bad for the heart]
  3. The amounts of vitamins aren’t crazy. I roll my eyes when I see mega-doses of Vitamin B12 (which doesn’t actually do anything unless you’re deficient), or any fortification with Vitamin B5 (which is in almost every food group imaginable so there’s no need to fortify). Some supplements go a little overboard with Vitamin B3, but over 35mg of this can make some people flush and itchy. The B-vitamins are water-soluble, but that doesn’t mean that more is better.

    Celsius Raspberry Acai Green Tea GreenEyedGuide
    Product Claims
  4. The product claims highlight the ways this product is different from the energy drink stereotype. Even their Warning Statement is grammatically correct: “Not recommended for people who are caffeine sensitive, children under 12, or women pregnant or nursing.” I can’t help but chuckle when I read a Warning Statement that says, “Consult with a healthcare professional if you are pregnant.” Gee, thanks for the tip, but I was going to ride these 9 months doctor-free and deliver in a bathtub. In contrast to the warning statement which offers general health advice and cannot be read literally, Celsius’s statement actually refers to the product.
  5.  The label makes it very obvious this product does not magically make your fat disappear. Celsius is your workout buddy, your “Ultimate Fitness Partner”, and it’s made clear in the side-panel Marketing blurb the product doesn’t work if you’re not exercising.

FIVE BURNS of Celsius – The NEGATIVE POINTS

  1. The words “clinically proven” makes me raise my eyebrows as a scientist. It’s actually rather difficult to clinically prove anything related to weight-loss because there’s always confounding factors. In this case, the increased metabolism, reduced body fat, and improved endurance are typical results of studies that make people exercise, especially if any type of caffeine is involved. It’s common knowledge caffeine improves athletic performance, but the magnitude of those improvements depend on whether the person is an athlete or a gym rat; an occasional coffee drinker or a coffee/tea-holic.
  2. The front of the can says, “Your Calorie-Reducing drink” and yet there is a supplement facts panel. A product is not allowed to have a supplement facts panel if it is referred to as a “drink” or beverage. If it is truly a drink, it must have a “Nutrition Facts” panel, while supplements need a “Supplement Facts” panel and have different regulations for the fact panel layout and content. This may not seem like a big deal, but there are countless FDA Warning letters to companies that demonstrate this product-category confusion.
  3. This product always dries my mouth out. This astringent effect is common with certain tannins in tea and Premium Brewed Green Tea is a predominant ingredient. Ginger root extract may also affect some people this way.
  4. While the amount of caffeine is stated, there are other components of the “Meta-Plus Proprietary Blend” that I would prefer to see itemized. For instance, how much taurine and green tea leaf extract? How much ginger root? The missing amounts don’t concern me as a consumer, but knowing those amounts would fascinate me as a scientist.
  5. Again, the diction grammar bothers me. The side panel of this product says “Celsius burns up to 100 extra calories and more.” How can you burn UP TO 100 calories AND MORE? Which one is it? Also, the expression “calorie reducing” isn’t exactly the same thing as burning calories, but Celsius, the “calorie reducing drink” is supposed to help one burn more calories. Add in the fact that a calorie is a unit measuring energy and the “calorie reducing drink” that gives one “lasting energy”, and we’ve got QUITE THE PARADOX!

BOTTOM LINE

Overall this is not my favorite product, but it’s one that I do enjoy from time to time. Since it’s not carbonated, it’s less likely to upset my stomach if I drink it en route to my morning workout. There is a decent kick from the caffeine, but as a science-nerd I get just as big a kick out of reading the label. There’s nothing wrong with the ingredients but the caffeine may be strong for some people. If this product and its calorie-reducing promises help you commit to going to the gym instead of going home or sleeping in, then it can be a great product to try at least once!
