Red Eye Energy Caffeine and Ingredients (Detailed)

Red Eye Energy Caffeine and Ingredients (Detailed)

Made in Australia, Red Eye Energy Drinks are for those who prefer their energy drinks to have a crisp, soda-y finish, with its use of carbonated spring water and various plant-based ingredients.

Of course, its texture and flavour only scratch the surface of Red Eye, so if you’re wondering what exactly goes into a bottle of Red Eye Energy, you’ve come to the right place.

For the basics, a 330ml bottle of Red Eye Energy has 149 calories, 106mg of caffeine, and 36.3g of sugar, along with other nutrients and additives such as B-Vitamins and herb extracts.

If you want a more in-depth look, read on to find out about the caffeine and ingredients of Red Eye Energy Drink through a detailed analysis.

How Many Calories Are In Red Eye Energy Drink?

Each 330ml bottle of Red Eye Energy Drink has 149 calories.

Considering that a 355ml can of Red Bull has 160 calories, Red Eye Energy has a pretty moderate amount of calories for a sugary energy drink.

Given that the average adult needs around 2000 to 2500 calories per day (depending on lifestyle choices and body metabolism), a bottle of Red Eye shouldn’t affect your diet or appetite too badly.

So while it’s not the best energy drink if you happen to watch your calorie intake closely, it’s still a pretty manageable amount, especially if you have an active lifestyle to burn off said calories.

Fair warning, though, while one bottle may have a reasonable amount of calories, having more than one bottle will definitely make those calories pile up, which may lead to you having excessive calories in your diet.

So be sure to limit how many bottles of Red Eye you have a day, and try to have a full meal instead of an energy drink if you’re feeling peckish. Just because it gives you energy, doesn’t mean it’s nutritionally viable.

Red Eye Energy Drinks Ingredient Analysis

Now let’s take a look at the more prominent ingredients of Red Eye Energy Drinks and what each of them does.

Citric Acid

Citric Acid is a weak organic acid that you can find in most citrus fruits, such as lemon and orange.

That said, the citric acid found in Red Eye Energy Drink is man-made, unlike those found naturally in the aforementioned fruits.

Apart from adding a sour taste, the main use of citric acid in Red Eye would be as a preservative, helping to keep the drink fresh for a longer period of time. Other than that, there’s really not much else to it.


Taurine is an amino acid that’s often found in energy drinks, which supposedly has a multitude of benefits.

Taurine is a pretty common ingredient in various energy drinks and is present in the more popular ones such as Rockstar Energy and Red Bull.

As for the potential benefits of taurine, the list includes:

  • Promoting healthy metabolism
  • Improving exercise performance
  • Protecting the muscles

Despite this, the science doesn’t really prove that there are any immediate benefits of having taurine in your diet, so take the potential benefits with a grain of salt.


Inositol is a vitamin-like substance that is responsible for maintaining the balance of chemicals within your body as well as assisting insulin-functionings, and lowering blood sugar levels.

Some of inositol’s benefits include: improving symptoms of panic disorders and aiding in blood sugar control in people with type 2 diabetes.

While this sounds amazing, the majority of research done on inositol is solely on the ingredient itself, with higher dosages, so the effectiveness of inositol in Red Eye Energy Drink is somewhat questionable.

Given that there’s only 50mg of inositol present in Red Eye, it’s hard to say if you’ll derive any potential benefits from it.

On the bright side, 50mg is well within the upper tolerable intake limit for inositol (12g per day), so you don’t have to worry about suffering from any inositol related side-effects.

Guarana Extract

A plant native to Brazil, Guarana contains a wide range of stimulants inclusive of caffeine, theophylline, theobromine, and antioxidants.

Research suggests that Guarana not only gives you a quick energy boost but also helps with reducing fatigue, which makes it a great ingredient to have in an energy drink.

That being said, the majority of Guarana’s purported benefits is due to its caffeine content, which makes it pretty susceptible to caffeine’s shortcomings too.

In any case, while the guarana content in Red Eye may be a sneaky way of adding more caffeine into the drink, the caffeine content is relatively low, so there really shouldn’t be any issues.

Ginkgo Biloba

Ginkgo Biloba is a tree native to East Asia that is known to be one of the oldest, living tree species on the planet.

As for its benefits, ginkgo biloba may help in:

  • Reducing symptoms of anxiety
  • Contain powerful antioxidants
  • Improving circulation and heart health
  • Improving brain function
  • Supporting vision and eye health

While this sounds pretty good, keep in mind that we don’t quite know how much Ginkgo Biloba is present in Red Eye, so a healthy pinch of salt is probably in order with regard to any potential benefits that it might have in Red Eye Energy.

Ginseng Extract

Ginseng is a natural herb that’s used in food and remedies. It’s also a prominent ingredient in most energy drinks, most notably used by Rockstar and REIZE.

Ginseng has a bunch of potential benefits such as:

  • Increasing energy
  • Sharpening cognitive function
  • Anti-inflammatory effects
  • Reducing blood sugar

If you would like more information on ginseng and what it does, I’ve written an article detailing everything you need to know about ginseng here.

Gotu Kola

Gotu Kola, or the Centella Asiatica plant, is a herb often used in traditional Chinese medicine that contains certain chemicals that seem to decrease inflammation and reduces blood pressure in veins.

As with most ingredients, we don’t exactly know how much of it is present in Red Eye, but it should be relatively low enough that it won’t cause any serious side effects.


Ginger is a notable spice and flavouring ingredient that’s used in various cultures as remedies.

Apart from the flavouring, ginger is most prominently used for treating upset stomachs and nausea, but apart from that, there’s not really much else to ginger.

Green Tea Extract

Fancy some green tea?

Green tea is a tea that’s derived from the Camellia sinensis plant, which has a unique taste and green colouration. Its popularity has made it a common flavour in confectionaries, desserts, and beverages.

Green tea’s benefits are mostly derived from the polyphenols, which include, but are not limited to:

  • Reducing the risk of cardiovascular disease
  • Reducing the risk of certain forms of cancer
  • Reducing the risk of developing high blood pressure
  • Promoting oral health
  • Reducing cholesterol levels

As with guarana, green tea also contains 2 to 4% caffeine, which makes it a helpful ingredient in preventing fatigue.


Grape seed extracts are known to be beneficial for several cardiovascular conditions such as improving overall circulation, and issues pertaining to high cholesterol.

They also contain antioxidants, which protect the cells and prevent a multitude of diseases.

That said, we don’t quite know how much grape seed extract is in Red Eye Energy Drink, so while the extract may be helpful, it’s unclear to what extent it may add antioxidants to your system.


B-Vitamins are found in just about every energy drink, and Red Eye Energy Drinks are no exception.

Oddly enough, while Riboflavin (Vitamin B2) is stated to be present in Red Eye Energy Drink, the nutritional label doesn’t specify exactly how much of it is present.

In any case, here is the B-Vitamins present in Red Eye Energy Drinks. For a more in-depth look at B-vitamins, click on the link here.

A brief look at the B-Vitamins in Red Eye.

How Much Caffeine Is In A Red Eye?

There’s 106mg of caffeine per 355ml of Red Eye Energy Drink, which is a fairly low amount for an energy drink that size.

If you’re drinking an energy drink, the caffeine content is probably the most important thing, as it’s the main ingredient that helps keep you awake, as well as improve cognitive function and exercise performance.

Considering that the caffeine content in energy drinks can range between 50 to 300mg per serving, Red Eye seems to slide into the sweet spot of just having a caffeine content below the 160mg average.

Personally, I prefer my energy drinks to have between 50 to 100mg of caffeine per serving, which is just the right amount to give me a boost, but not too much that I might get a headache afterward.

As such, a bottle of Red Eye is not that much higher than what I would usually go for, but depending on your caffeine sensitivity and caffeine metabolism, you might need a little bit more to feel the effects.

As a reminder, the most important thing when it comes to caffeine and energy drinks is not how much caffeine is present, but more about how much caffeine you can tolerate.

As a general warning, the American FDA approves a caffeine intake limit of no more than 400mg per day. Any more than that might lead to side effects such as:

  • Insomnia
  • Restlessness
  • Headaches
  • Stomachaches
  • Dizziness
  • Dehydration
  • Anxiety

In any case, so long as you’re not having 4 bottles of Red Eye a day, you should be pretty safe from experiencing any caffeine-related side effects.

How Much Sugar Is In A Red Eye?

There’s 36.3g of sugar in each 330ml bottle of Red Eye Energy.

For reference, 36.3g of sugar is roughly equivalent to 2.5 tablespoons, which is quite a lot of sugar.

When considering how much sugar you should have a day, you should know that the American Heart Association (AHA) recommends a maximum daily added sugar intake of 25g for women and 36g for men.

Knowing this, a bottle of Red Eye, while mostly within the limit, is still a bit more than what you should be having in a single day.

Now that’s not to say you can’t have sugar every now as a treat in small servings, but having too much sugar consistently is a definite problem.

Some of the issues of having a high-sugar diet include:

  • Weight Gain
  • Type II Diabetes
  • Increased risk of heart disease
  • Acne
  • Increased risk of depression

You also run the risk of suffering from a sugar crash with sugary energy drinks due to the spike and fall in blood sugar after you’ve had one.

As with most things in life, it’s best to moderate your energy drink consumption within reasonable levels, so try to cut down on the sugar, especially if you have a fondness for sugary energy drinks.

If you would like some energy drinks where you don’t have to worry about the sugar content, check out the article I’ve written on the best zero-calorie energy drinks for some great alternatives.

Is Red Eye Energy Drink Bad For You?

As long as you’re healthy and know how to moderate your consumption, having a Red Eye Energy Drink every now and then should be perfectly fine.

A majority of the potential side effects you might have from Red Eye boils down to whether or not you’re able to tolerate its caffeine content.

Considering that there’s only 106mg of caffeine present in a 335ml bottle of Red Eye, it’s less likely that Red Eye might cause side effects from too much caffeine unless you’re sensitive to caffeine.

That being said, Red Eye does have a significant amount of sugar in it, so be sure you’re not having too many per day if you would like to stay on the healthier side of life.
