Have you ever looked at an energy drink and thought, “Is this good for me?” Don’t laugh – this question is not rhetorical. In fact, I’ve studied energy drinks for almost 20 years and I get this question all the time. My friends, family, and fans will send me pictures and ask, “What about this drink?” Some drinks are DEFINITELY better than others. And so today we’re going to focus on the Science Behind Kill Cliff Ignite.
Hi there. I'm Caffeine Scientist, Author, and Speaker GreenEyedGuide. I help people beat burnout with caffeine science.
More than 90% of the population drinks caffeine every day. But when and how you drink your caffeine makes a huge difference in your health and well-being.I use my science background to help people drink caffeine strategically. In other words, I help people work better, sleep better, and feel better.
Picture the stereotypical cup of tea. Now picture the stereotypical energy drink. Could these images be any different? While tea represents a relaxed mood and health, energy drinks represent hyperactivity and danger. So what happens when you add energy drink ingredients to tea? When is tea more than “just tea”? When is green tea an energy drink?
For this exercise, let’s consider a specific drink. This drink is a blend of green tea, yerba mate, and green coffee beans. Sounds healthy, right? But how does it compare to plain tea? To Red Bull? We’ll go over that, plus the three criteria make this green tea an energy drink.

Hi there. I'm Caffeine Scientist, Author, and Speaker GreenEyedGuide. I use caffeine science to help people beat burnout.
Following your passion requires vision, commitment, persistence, and long hours. October challenges your vision and commitment because it brings shorter days, midterms, the distractions of a looming Holiday Season, and the time crunch to meet End of the Year company objectives. This month, we review an energy drink-in-disguise designed to “complement your work hard/play hard lifestyle” with green coffee beans, monk fruit, erythritol, and coconut water. Read more →
September gives us lots of reasons to feel tired. Maybe you’re a student, trying to get back on a school schedule. Or maybe you’re a parent trying to savor the last days of summer. Whatever is draining your energy, I’ve got another energy drink alternative for you: Guru Energy Water.
In this post, I’ll outline why Guru Energy Water doesn’t look or taste like a stereotypical energy drink. But that’s no surprise considering Red Bull is older than the people entering college this fall. We’ve come a long way since Red Bull and Monster first hit the US markets. Guru Energy Water is more proof of that.
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 istea 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.
Core Organic
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.
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:
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)
You are avoiding artificial sweeteners – This drink is sweetened with Stevia and Organic erythritol (we’ll review this below)
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
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
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.
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.
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.
