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… 🤓💚🔬⛾📚

Ingredient Focus: Citrulline Part 2 – What It Does

In Part 1, we used grapes and toothpicks to understand what citrulline is. In part 2, we discuss what it does.

Like a watermelon seed, the best part of citrulline is not what it is, but what it becomes: arginine. When citrulline is ingested, it is converted into the amino acid arginine.

Energy Drink of the Month – June 2016: WTRMLN WTR

What’s going on? Why is WTRMLN WTR on an energy drink blog? Because dehydration causes fatigue, and the solution (pun intended) for Level 1 of the Five Levels of Fatigue is water. With summer in full swing, it’s the perfect time to review the ingredients, hydration power, and food science behind this watermelon hydration drink.

The Energy Drink of the Month for June 2016 is WTRMLN WTR.

GreenEyedGuide.com Energy Drink of the Month for June 2016 is WTRMLN WTR.
GreenEyedGuide.com Energy Drink of the Month for June 2016 is WTRMLN WTR.

Yes, this is literally the water from a watermelon, not water that’s been enhanced with fruit juice extracts or add-ins. Food Waste is a growing concern among food scientists (and consumers!) so I was overjoyed when I learned that this product is made from watermelons that would otherwise be discarded.

Ingredients

WTRMLN WTR Nutrition Facts and Ingredients - GreenEyedGuide Energy Drink of the Month June 2016
WTRMLN WTR Nutrition Facts and Ingredients – GreenEyedGuide Energy Drink of the Month June 2016

This drink is a little bit sneaky with its serving size. One bottle is actually one AND A HALF servings, and the Fact Panel pretends you’re only going to drink two-thirds of the container (8 of 12 ounces). This is a pet peeve of mine, but the new FDA food labeling regulations should resolve this.

One reason this serving size decision bothers me is that the label compares the sugar and electrolyte content of WTRMLN WTR, orange juice, and coconut juice. These comparisons are “per serving”, but that is not helpful because the serving size is arbitrary. If you Googled “what is one serving of fruit juice”, you’d find the American Heart Association explain that one serving of fruit is one whole medium-sized fruit or one-half cup (4 ounces!) of fruit juice. And yet one whole 12 oz bottle of orange juice can also be labeled one serving.

With this inconsistency, it’s better to compare the nutrients per ounce than per serving.

Nutrient comparisons per ounce, not by serving size — Gatorade vs VitaCocoa vs Tropicana Orange Juice vs WTRMLN WTR

Hydration Power

WTRMLN WTR label GreenEyedGuide Energy Drink of the Month June 2016
WTRMLN WTR lays out the people and situations this product is suited for…

The ideal hydration beverage has 6-8% carbohydrates, according to the research review article, “The effectiveness of commercially available sports drinks.” In the table above, Gatorade falls in that ideal range – shocker – but so does WTRMLN WTR. When are these hydration beverages most effective? According to this same research review article:

  • Consumption during short duration high-intensity exercise may enhance performance
  • Consumption during prolonged intermittent exercise can improve performance
  • Consumption during prolonged exercise (meaning 1-4 hours) may enhance performance

Food Science – What is Citrulline?

WTRMLN WTR What is Citrulline - GreenEyedGuide Energy Drink of the Month
Did you notice the “bedroom” claim on the label? Citrulline has some pretty interesting use cases involving the Urea Cycle, Nitric Oxide Metabolism, and muscle fatigue!

The more I read about citrulline, the more I wanted to learn about it. A “deep dive” on this ingredient is forthcoming later this month, but here are some key facts you should know.

  1. Citrulline is also known as watermelon extract.
  2. Citrulline gets its name from watermelon – watermelon’s Latin botanical name is Citrullus vulgaris.
  3. One average watermelon contains 2.1mg citrulline per gram
  4. In the sports supplement world, people take citrulline (as L-citrulline or citrulline malate) to increase the levels of amino acid arginine in the body
  5. The kidneys turn citrulline into arginine, which is supposed to delay muscular fatigue [Bodybuilding.com’s Complete 2016 Supplement Guide rates this ingredient/function claim as “Great: Inconclusive findings but anecdotal evidence is favorable and the ingredient is considered safe for use”

Comparisons and Conclusions

How does this drink hold up to plain old water? Well, it’s certainly tastier, and potentially more expensive. If you’re one of those people that have a hard time drinking enough water throughout the day, this product could be one way to drink more.

How does this drink hold up to orange juice? Comparing ounce-per-ounce instead of tripping over serving sizes, WTRMLN WTR has fewer calories and fewer grams of sugar. It also has less Vitamin C.

How does this drink hold up to other watermelon beverages we’ve reviewed at GreenEyedGuide? Well, WTRMLN WTR is not caffeinated, so if you’re one of those people who need help getting up for your 5 am workouts, WTRMLN WTR may not be the best pre-workout drink.

My initials are DR but I’m not a doctor, so take my insight with a grain of salt and take all caffeinated beverages with a tall glass of water.
