Science Behind EMV Jabu Energy Drink – Quick Review

Science behind Jabu Emv

Notable Ingredients

  • green tea leaf extract
  • guarana seed extract
  • yerba mate leaf extract
  • stevia and isomaltulose

Interesting and Unusual Ingredients In This Energy Drink

Isomaltulose is a natural sweetener found in honey and sugar cane extract. It has the same two “members” that make table sugar: glucose + fructose = sucrose. However the glucose and fructose are arranged (i.e., holding hands) in a different way than they do in sucrose.  As a result of this arrangement, isomaltulose is only half as sweet as sucrose.

This energy drink contains JABUTICABA, which is basically a Brazilian grape. Jabuticaba fruit contains protein, calcium, iron, phosphorus, Vitamin C and some B vitamins.

Jabuticaba has polyphenol antioxidants like those in cranberries and grapes. These antioxidants have been shown to have anti-inflammatory and anti-cancer properties…in test tubes and lab rats. It’s difficult to prove these benefits outside of a controlled cell or rat cage because life is too complicated to prove a cause and effect of this magnitude.  In other words, it’s extremely difficult to control for things like diet, stress, sunlight, exercise, the number of hours sitting down, etc. to conclusively prove whether polyphenols prevent cancer.

When Juice Becomes A Tool

Jabuticaba isn’t very high on the ingredients list, meaning there might not be enough of it in this drink to be an effective dose for those antioxidant health benefits. The same can be said for the other juices in here too: apple, grape, acai, and acerola. All of these juices offer some variety of health benefits related to the benefit of antioxidants. But the dosage makes a difference. So does the order.

Apple and Grape juice are the most predominant, and they are very sweet, which tells me this drink is using those juices more for flavor and sweetness than for health benefits.

Regardless, this is a healthier alternative to the stereotypical energy drink. This energy drink has 80 mg caffeine (same as Red Bull) from 3 leaf extracts: 1.Green Tea, 2.Guarana, 3.Yerba Mate. With 80 mg caffeine, this drink fits Fatigue Level 2. [See 5 Levels of Fatigue to see how to use this system to avoid caffeine toxicity, dependency, and tolerance]

Energy Drink of the Month – September 2017: Guru Energy Water

The year I started college, Monster and Rockstar were just hitting US markets. Welcome to September 2017, where Red Bull is older than the people entering college this fall. Whether you’re a student, a parent of school-age kids, or an adult savoring the last days of summer, September can bring changes that drain your energy. It’s a great time to consider a new energy drink, but one that won’t blow your summer body, one that keeps you hydrated and refreshed through the summer heat, and one that isn’t too strong. After all, you want to save those strong energy drinks for finals week and Black Friday shopping. Read more

Energy Drink of the Month – May 2017: Zevia Zero Calorie Energy

Sometimes we just want life to be simple. In high school, life was not simple, but at least my schedule was predictable. Each hour was dedicated to a specific subject; a chiming bell was enough to break my To Do list into neat little blocks of time. With graduation season upon us, many will leave their predictable schedules and somewhat-organized world for the unpredictable chaos that comes with adulthood. As a tribute to that unavoidable complexity, this month we review (yet another) energy drink with clean, simple ingredients. If you’re familiar with my mission on GreenEyedGuide.com, you know I love nothing more than busting the energy drink stereotype.

This month’s pick is another “energy drink in disguise” that doesn’t fit the water, juice, tea, or soda category. With 120 milligrams of caffeine per can, it’s undeniably an energy drink but also undoubtedly not “a deadly concoction of caffeine and sugar”.  

The Energy Drink of the Month for May 2017 is Zevia Zero Calorie Energy.

Zevia’s new energy drink line

At the time of this post, there were four flavors available: Grapefruit, Kola, Mango/Ginger, and Raspberry/Lime. They all have 120 milligrams of caffeine per can, zero Calories, zero grams of sugar, zero vitamins, zero preservatives (not counting the acids), and nearly identical ingredient lists. As you might’ve guessed from our other Energy Drink of the Month winners, I’m a berry person, so my favorite is Raspberry/Lime.

Key Ingredients 

Carbonated Water

We’ve talked about carbonation many times before, so here’s some refreshing (pun!) insight from Popular Science’s article on why humans like fizzy drinks

“Chemically, adding CO2 to water creates carbonic acid, which is tasted by sour-sensing taste cells. Research has suggested that a certain enzyme, carbonic anhydrase, sits on those cells and reacts with the acid to cause carbonated water’s familiar popping sensation. (Fun fact: climbers who take altitude-sickness drugs that block the enzyme, then drink champagne, report the bubbly as having a dishwater-y taste.”

Citric Acid and Tartaric Acid

The Kola flavored Zevia Zero Calorie Energy has tartaric acid and citric acid, whereas the other three just have citric acid. This excellent infographic from our friends at Compound Interest explains the science behind these two popular acids.

Stevia Leaf Extract

Finding a high-quality stevia extract is no simple task. Oh sure, we know what molecule is responsible for the sweetness, but isolating that molecule and delivering it is far more complicated than producing table sugar. Sugar is sugar is sugar, right? But water doesn’t always taste the same, even if it’s just water. The same goes for Stevia. In fact, tasting Stevia samples was one of the tasks I dreaded most while I worked as a product developer for a major supplement company. One bad sample, and you’d be experiencing a bitter metallic aftertaste the rest of the day (or week: See “A Food Science Horror Story”).

It turns out that some people are Stevia Super Tasters so they will get a bitter metallic aftertaste with Stevia when many others would taste only sweetness. This bitter metallic aftertaste is why stevia is often paired with another natural sweetener, erythritol.

Caffeine Comparison 

The top three best-selling energy drink brands are Red Bull (80 mg caffeine per 8 oz can; 114 mg caffeine per 12 oz can), Monster Energy (160 mg caffeine per 16 oz can), and Rockstar Energy (240 mg caffeine per can, most flavors). Since Zevia Zero Calorie Energy is an “energy drink in disguise” that breaks the energy drink stereotype, it makes more sense to compare its caffeine content to similar products, other healthy alternatives.  Below are the caffeine contents listed in the Caffeine Informer database:

When to Consume = Fatigue Level 3 

When it comes to caffeine content, 200 and 400 are special numbers. Quoting from the “Scientific Opinion on the safety of caffeine” from the European Food Safety Authority:

“Following a request from the European Commission, the EFSA Panel on Dietetic Products, Nutrition and Allergies was asked to deliver a scientific opinion on the safety of caffeine, providing advice on caffeine intakes, from all dietary sources that do not give rise to concerns about adverse health effects for the general healthy population and subgroups thereof. Possible interactions between caffeine and other constituents of so-called “energy drinks”, alcohol, p-synephrine and physical exercise should also be addressed. Single doses of caffeine up to 200 mg (about 3 mg/kg bw for a 70-kg adult) do not give rise to safety concerns. The same amount does not give rise to safety concerns when consumed < 2 hours prior to intense physical exercise under normal environmental conditions. … Habitual caffeine consumption up to 400 mg per day does not give rise to safety concerns for non-pregnant adults…” 

The 5 Levels of Fatigue is a system I developed during my years of researching energy drinks. The 5 Levels of Fatigue helps people find the product most appropriate for how tired they are, thus minimizing caffeine dependence, toxicity, and tolerance. Anything with more than 200 milligrams caffeine should be saved for more dire energy emergencies like Fatigue Level 4. A product with 100-200 mg caffeine belongs with Fatigue Level 3. Since this product has 125 milligrams of caffeine per can, this product fits Fatigue Level 3. It is a carbonated product, which usually means the caffeine would feel stronger than a non-carbonated equivalent like the caffeinated (still) water from Avitae due to carbonation’s effects on the stomach.

Bottom Line 

If you are looking for a strong, sugar-free, artificial-free carbonated energy drink Zevia is a great option. You don’t have to fret about “the dangerous of energy drinks” with this product. Zevia Zero Calorie Energy is simple. Life is complex enough.

Review the entire ENERGY DRINK OF THE MONTH SERIES

Let’s connect!

Energy Drink of the Month – December 2016: Core Organic

How do you describe a beverage that is a hybrid of juice, water, and tea? This month we’ll review a beverage that aims to give you the health benefits of tea, the hydration of water, and the flavor of fruit juice. While the caffeine content is negligible, there is tea in it, and Fatigue Level 1 is dehydration! We’ll review WHO IT’S FOR (per diet/lifestyle and ingredient preferences), WHAT’S IN IT (key ingredients), and WHEN TO CONSUME IT (per caffeine content and the 5 Levels of Fatigue).

*Spoiler Alert* I’ve got three minor Food Scientist pet peeves with this beverage, and I would love to hear your thoughts on these observations.

The Energy Drink (alternative) of the Month is Core Organic Pomegranate Blue Acai.

Other flavors available include Peach Mango, Watermelon Lemonade, Orange Clementine, Coconut Colada, and Orchard Pear. If you’re familiar with my Energy Drink of the Month series, you know I almost always pick the pomegranate blueberry flavors.

WHO IT’S FOR

This Core Organic “fruit infused beverage” is certified Organic, non-GMO, gluten-free, low glycemic, and Vegan.

20161213_232927

  • PET PEEVE #1: Gluten is a protein found in wheat, barley, and rye.
    • Why would any of those be in a fruit-infused beverage? Does anyone else feel like Core Organic is trying to win consumers by tapping into that fad?

This beverage could appeal to you if:

  1. You are limiting your sugar intake and your “liquid calories” – This drink has less than 1 gram of sugar per serving and only 5 Calories per serving (10 Calories per bottle)
  2. You are avoiding artificial sweeteners – This drink is sweetened with Stevia and Organic erythritol (we’ll review this below)
  3. You are avoiding artificial colors and/or flavors – The color comes from Organic vegetable juice and fruit juice, and the flavor comes from a combination of natural flavors
  4. You are not really a tea drinker but still want the benefits of drinking tea – This drink has 75 milligrams of polyphenol antioxidants, which is “the antioxidants of half a cup of blueberries or cherries” according to the press release in BevNET

core-organic-pomegranate-blue-acai-ingredients

WHAT’S IN IT

Fruit Juice

  • PET PEEVE #2: This is a “fruit infused” beverage but the fruit juice doesn’t play a very big role. 

There’s only 4% juice per serving. The FDA does consider coconut water a juice, but since it’s behind erythritol in the ingredient’s list, we know there’s more erythritol than coconut water in this drink.

The Organic lemon juice is behind the Stevia extract, which is very telling! Since Stevia is something you can’t use in large amounts, there can’t be more than one lemon’s worth of lemon juice in here. Since the lemon juice comes before citric acid, it seems both the lemon juice and the citric acid are in this drink to control acidity. If you want to keep mold out of your fruit juices, you have to either control the acidity or use preservatives.

The last two fruit juices are the last two ingredients in the list, meaning they’re the smallest portions of the recipe. There’s fruit juice used for color, and Maqui berry juice powder used to deliver antioxidants.

5-in-1 weight loss supplement combo IS effective, but thanks to WHICH combo?

White Tea, Maqui Berry, and Polyphenol Antioxidants

The good news is consumption of polyphenol antioxidants is associated with improved cardiovascular health and reduced risk of cancer. Consumption of green and white tea is associated with lower risk of cancer, diabetes, cardiovascular disease, and Alzheimer’s disease. The bad news is white tea is such a small portion of this recipe, and Maqui berry is literally the last/most sparse ingredient!

Maqui berry is a “Chilean blackberry”, according to a paper in the Journal of the Science of Food and Agriculture. It might have a lot of antioxidants in nature but one paper suggests the juice making process results in a “substantial loss” of the polyphenol antioxidants in Maqui. If you can figure out how to minimize these losses, there are some encouraging (but still uncertain) health benefits. A group of antioxidants called “anthocyanins” extracted from Maqui berry improved fasting blood sugar levels in (wait for it) obese diabetic mice.

“Animal research can be useful, and can predict effects also seen in humans. However, observed effects can also differ, so subsequent human trials are required before a particular effect can be said to be seen in humans. Tests on isolated cells can also produce different results to those in the body.” – see the Compound Interest infographic on Scientific Evidence

Erythritol

Erythritol is one of my favorite sweeteners, and we’ve talked about it before in other reviews. Erythritol makes Stevia better when they’re combined. Some people get a bitter-metallic sensation with Stevia extract, but erythritol masks the unfavorable attributes of Stevia. Erythritol is 60-70% as sweet as sucrose and has a very similar taste. It does not raise blood glucose levels and it delivers a cooling effect. While it’s non-caloric like Stevia, it has a molecular size that gives it more mouthfeel. Think fruit juice versus fruit smoothie: the fruit smoothie has a heavier “mouthfeel”.

Erythritol occurs naturally, like monk fruit and Stevia. It’s made through natural fermentation. It’s a sugar-alcohol, like the Xylitol often used in sugar-free gum. With xylitol, however, too much of it can really upset a person’s stomach. With erythritol, a person could consume twice as much – at least 0.66 grams per kilogram of body weight – before they started getting same stomach issues. Additionally, erythritol has been proven through clinical studies to reduce plaque build-up.

Core Organic beverage nutrition facts ingredients caffeine content
Caffeine content is “about the same as a cup of decaf coffee”, so does that mean 45mg? There is no standard for this!

WHEN TO CONSUME

  • PET PEEVE #3: There is no such thing as a standard cup of coffee or cup of tea.
    • It’s not clear how much caffeine is in this product, but we should assume the content is negligible. The white tea is the only source of caffeine, and white tea is not a very prominent ingredient.

Core Organic is not promoting itself as a drink that would give you energy, but since it includes white tea extract, I wish they could include some caffeine information on the label.

Dehydration is Fatigue Level 1, so picking a beverage with negligible caffeine content is a great way to ensure you don’t reach for the caffeine too soon. If you always reach for the same caffeinated beverage, and if caffeine is always your first solution when you’re tired, there will come a day when the caffeine no longer works for you. This is precisely why I developed the 5 Levels of Fatigue!

Bottom Line

This water/juice/tea hybrid is not marketed as an energy drink, but it’s a good solution (pun intended) for beating the fatigue that comes with dehydration. While you will not get the full benefits of drinking plain tea, you still get the benefits of the 75 milligrams of polyphenol antioxidants per serving.

Energy Drink of the Month – February 2016: Bai Antioxidant Infusion

Bai Antioxidant Infusion is one of those “energy drinks in disguise” I love reviewing because it breaks the norm AND withstands a food scientist’s ingredient scrutiny. Bai Antioxidant Infusion (HENCEFORTH ‘B.A.I.’) is an “energy drink in disguise’ with only 35 mg caffeine, and a novel blend of white tea, polyphenols, and coffeefruit extract. Coffeefruit is not an ingredient many people have heard of, but its story of discovery is a shining example to those concerned about food waste. After reviewing the food science of B.A.I.’s most interesting ingredients, we’ll compare the “healthiness” of this product to other tea-based beverages and similar energy drinks.
