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]

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?

*READ “Coffeefruit extract – a food waste triumph” here: Energy Drink of the Month – Feb 2016: Bai Antioxidant Infusion

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: ]

Monster Ultra Violet (“Monster Purple”)

What do TAURINE & CARNITINE DO? Science Behind Monster Purple (Ultra Violet)
✔ Taurine is a 🚕Taxi Cab🚕
✔CARNITINE a doorman,
✔taurine & carnitine are in an “ENERGY BLEND” and
✔how much caffeine is in Monster (relative to safety limits for caffeine ingestion).

Energy Drink of the Month – March 2017: MATI Healthy Energy

This month we examine another energy-drink-in-disguise, the health benefits of the ingredients, and the caffeine comparisons to similar products. This product has one of the simplest ingredient lines I’ve ever seen, and it lives up to the “Healthy Energy” proclaimed on the label.

The Energy Drink of the Month for March 2017 is MATI Healthy Energy.


There are six flavors available, and all of them are delicious (though taste is subjective): Citrus, Cherry, Tropical, Peach Mango, Passion Fruit, and Berry Pomegranate. They all have the same caffeine content, 30% juice, and the same number of Calories and grams of Sugar. They vary in the fruit juices, but they all have guayusa leaves, apple juice, lime juice, and natural flavor.

Key Ingredients and Benefits


Guayusa is a natural source of caffeine. Pronounced “gwhy-you-sa”, this plant is the Amazonian cousin of yerba mate. While the leaves of guayusa are brewed like tea leaves, the lack of tannins means less of the bitter, astringent taste that’s characteristic of green, black and white teas.

Guayusa leaves contain twice the antioxidants of green tea, and MATI is equivalent to three cups of it, according to the “Nutritional Equivalents” on the can. Guayusa also contains essential amino acids, though the energy drink itself contains only 1 gram of protein. Traditional use of guayusa includes consumption before nighttime hunting trips, as the guayusa gave the hunters mental strength, courage, and focus. It’s not clear what “mental strength” is, exactly, but you can count on almost any caffeine source to increase stamina and focus.

Apple Juice

All six flavors of MATI include apple juice, which isn’t surprising when you realize fruit juices are solely responsible for the beverage’s sweetness. With no added sugar, you need a juice that is naturally sweet, like white grape or apple juice. But apple juice provides health benefits with its sweetness.

The main benefits of consuming apples comes from the antioxidants known as polyphenols. Apple juice concentrate contains approximately 20 ppm epicatechin, and 70 ppm chlorogenic acid. For context, 200 grams of apples contains about 21 milligrams of catechins. The largest group of polyphenol antioxidants in apple juice is the flavanols (50%), followed by the hydroxycinnamic acids such as chlorogenic acid (43%).

Apple consumption is linked to reduced risk of some cancers, cardiovascular disease, asthma, and diabetes. These benefits are associated with the polyphenols in apples, but processing the apples into juice does reduce the polyphenol content. For example, some polyphenols like the flavanols have an affinity for the cell wall and thus get retained in the mash.

Other ingredients

  • Lime Juice – helps control pH and thus acts as a natural preservative in a beverage with only fruit juices and caffeine; controlling pH helps limit the growth of yeast, mold, and other bacteria that like to thrive in juice beverages
  • Natural Flavors – fruit juice can add a lot of its own flavor, but it may not be strong enough to cover the taste of guayusa; a natural flavor is great way to make sure the taste of the beverage doesn’t drift too much through the beverage’s shelf-life — in other words, a natural flavor will make sure the product tastes as yummy on Day 1 as it does the day before it expires


Caffeine Comparisons

MATI has 110 mg caffeine per can, which is slightly less than the caffeine in Red Bull 12-ounce Editions, and less than a Starbucks bottled iced coffee. MATI has slightly more caffeine than the similar drinks that contain 100 mg caffeine, such as Steaz, Nawgan, and Go Girl.

Fatigue Level 2

During the GreenEyedGuide Caffeine Challenge (Day 8), we talked about how Fatigue Level 2 is basically where all the healthy energy drink alternatives live. At Fatigue Level 2, you’re not just dehydrated-tired, but you don’t need a full-powered kick of a stereotypical energy drink. This drink fits Fatigue Level 2/Borderline Level 3 situations because is has the following characteristics:

  • Fruit juice-based (30% Juice)
  • Lightly carbonated
  • 110 mg caffeine

To learn more about how carbonation and juice play a role in a drink’s potency, visit the 5 Levels of Fatigue page. The 5 Levels of Fatigue system helps people reap the benefits of caffeine while avoiding addiction, dependence, tolerance, and toxicity,

Bottom Line

This energy-drink-in-disguise lives up to its Healthy Energy label. With only 45 Calories per can, 11 grams of sugar (all from juice), and 110 mg caffeine from guayusa leaves, this is an energy drink we can all get excited about.




Food Waste and a Master’s Thesis dream – GreenEyedGuide on ScienceMeetsFood

“This excerpt comes from the master’s thesis of a food scientist from UC Davis. That food scientist was me, Danielle Robertson, M.S. In my research, polyphenol procyanidin extracts were used, unsuccessfully, to prevent enzymatic browning in bananas. Seven years after that thesis was published, a company named Apeel Sciences has succeeded in creating an effective natural shelf-life extender entirely out of food waste. They succeeded where I did not, which is why I find this product so compelling.”

    Comparison with Similar Products

    Main Squeeze Antioxidant Beverage is a hybrid of an aloe drink, a coconut water drink, and a few “energy drink in disguise” products we’ve reviewed before here on GreenEyedGuide. Main Squeeze’s caffeine comes from green coffee beans, like Starbucks Refreshers. Both Main Squeeze and Pomegranate Blueberry Acai from Core Organic emphasize white tea and polyphenol content. The closest comparison to Main Squeeze would be Bai Antioxidant Infusion, so here are so points for comparison:

    Main Squeeze Versus Bai Antioxidant Infusion

    • Main Squeeze has 2x the amount of polyphenol antioxidants per bottle
    • Main Squeeze contains green coffee bean extract; Bai contains coffee fruit/coffee berry extract
    • Main Squeeze and Bai BOTH have 35mg caffeine per serving or 70 mg per bottle
    • Main Squeeze has 5% juice and 8% coconut water: Bai has 3% juice
    • Main Squeeze has 5 grams added sugars from Organic Agave Nectar; Bai has 1 gram of sugar and 8 grams erythritol

    Bottom Line

    An energy drink in disguise with the benefits of a hydration beverage, an antioxidant beverage, a green coffee bean energy drink, and an aloe drink – all rolled into one lovely bottle! With 70 mg caffeine per bottle, this beverage fits in the Fatigue Level 2 – when you’re not just tired from dehydration but need just a little boost. For more on the 5 Levels of Fatigue, see this overview.
