Decoding Energy Drinks: What You Need to Know About Their Ingredients and Effects

Most energy drinks are more than just caffeine containing beverages. From sugar and electrolytes to herbal extracts like ginseng and guarana, there are a whole host of ingredients in soft drinks that are added for enhanced physical performance... but do they also create adverse health effects?

This guide explores the content of energy drinks and takes a look at the consequence of energy drink overconsumption. But before you turn away from your first energy drink of the day, there's something important to remember: not all energy drinks are the same!

The golden rule is: check the ingredients, research any unknowns, and choose natural flavors. To help you determine the good energy drinks from the bad, you can find key info about some of the most common ingredients below.

The Content of Energy Drinks

When it comes to consuming energy drinks, especially for young adults, understanding the key ingredients is crucial to avoiding those jitters! From the caffeine content to other energy-boosting components, let's break down what goes into your favorite energy beverages.

Caffeine

When we talk about boosting your energy, we can't ignore caffeine. It's the powerhouse ingredient in most energy beverages. But what exactly is caffeine, and how does it impact your body and mind?

Caffeine is a natural stimulant found in coffee, tea, and various plants. It's known for its ability to increase energy and enhance mental focus, making it a popular choice in caffeinated energy drinks. When you consume caffeine, it quickly absorbs into your bloodstream and travels to your brain. Here, it blocks the inhibitory neurotransmitter adenosine, which helps you feel more awake and less tired.

Caffeine's effects on the body and mind are well-documented (and not just by us on the Zest Blog). It increases energy, enhances cognitive function, and can even boost athletic performance. Many athletes rely on caffeinated beverages to get that extra edge during workouts or competitions. By stimulating the central nervous system, caffeine can improve reaction times, alertness, and overall physical endurance.

The FDA recommends that healthy adults limit their daily caffeine intake to no more than 400mg. This is equivalent to roughly 2-3 Zest Energy Drinks.

Sugar

When discussing energy drink consumption, sugar is a key ingredient that often comes up. Found in many soft drinks and energy beverages, sugar can provide a quick energy boost. This is because sugar is a simple carbohydrate that the body rapidly converts into glucose, giving you an immediate surge in blood glucose levels. However, while this can be effective for a short-term energy lift, there are significant health effects to consider.

The media tends to make sugar seem like a villain... and they're not wrong.

High sugar content in energy drinks can lead to various health issues. Regularly consuming large amounts of sugar is linked to an increased risk of obesity, type 2 diabetes, and heart disease. It can also cause spikes and crashes in energy levels, which might leave you feeling more tired than before. For young adults, who are often the primary consumers of energy drinks, this can be particularly concerning (especially when you're trying to stay up all night to study).

Energy drinks can list sugar under various names, such as sucrose, glucose, dextrose, and cane sugar. These sugars contribute to the overall calorie count and can impact your health if consumed in excess. When choosing an energy drink, carefully consider the mg of caffeine it contains too, as both sugar and caffeine can affect your body's metabolism and weight loss efforts.

High Fructose Corn Syrup

High fructose corn syrup (HFCS) is another sweetener commonly found in energy drinks and energy shots. The American Beverage Association notes its widespread use in soft drinks, but it's also in sports nutrition drinks and energy drinks.

Yes, HFCS can contribute to obesity, diabetes, and other health issues, making it a significant risk factor in energy beverage consumption... but the science suggests it's no different to other forms of sugar for your health. As regulators and health experts want to better regulate energy drinks, you might see the caffeine content, sugar, and HFCS levels in your favorite energy beverages drop.

B-Vitamins

Did you know that energy drinks can be a source of vitamins?

B vitamins are the unsung heroes in many energy drinks, including Zest Energy Drinks which pack in B3, B5, B6, and B12. These water-soluble vitamins help you turn food into fuel and keep your metabolism humming.

Through the consumption of energy drinks, B vitamins can help you fight off mental fatigue and boost your sports performance. B3 (niacin) helps with energy production and DNA repair, B5 (pantothenic acid) supports hormone production and metabolism, B6 (pyridoxine) is key for brain function, and B12 (cobalamin) keeps your red blood cells and nerves in check.

While B vitamins bring plenty of positive effects, it’s all about balance. They’re water-soluble, so your body flushes out what it doesn’t need. You'll only feel a huge impact if your diet has an insufficient level of B vitamins.

Taurine

Taurine is a naturally occurring amino acid found in many energy drinks and energy shots. Often paired with caffeine, taurine helps enhance the overall impact of your energy boost. But what exactly does it do?

Taurine plays a crucial role in regulating water and mineral levels in your blood, supporting neurological development, and aiding in the digestion of fats. When combined with the caffeine content in energy drinks, taurine can supposedly help improve mental performance and reduce the jittery side effects some people experience from caffeine alone.

While taurine is generally considered safe, it's essential to keep an eye on your overall consumption of energy drinks to avoid potential adverse health effects from the sugar and caffeine. Balance is key - you can enjoy the benefits of taurine (which don't have the best scientific evidence, by the way) without overdoing it.

Energy beverages that contain taurine include:

• Monster Energy
• Red Bull
• Relentless
• Rockstar

Amino Acids

Amino acids are the building blocks of proteins and they play vital roles in almost every bodily function. But you won't see "amino acids" listed in the ingredients. In energy drinks, you'll often find specific amino acids like L-carnitine, taurine, and L-theanine.

L-theanine, in particular, is our favorite. Found in tea leaves, it’s known for enhancing mental performance and focus without the jitters (even when there's a high amount of caffeine). When paired with the mg of caffeine in your energy drink, L-theanine helps improve reaction time and cognitive function, making it an awesome ingredient in sports nutrition beverages.

While the consumption of energy drinks can give you a quick boost, amino acids like L-theanine ensure that boost is smooth and sustained, keeping you sharp and focused. Did you know that there's 100mg of L-theanine and up to 150mg of caffeine in Zest energy drinks? It's the perfect formula for controlled, focused energy.

Ginseng

Ginseng is a popular herbal supplement known for its impressive antioxidant and anti-inflammatory properties. Found in many energy drinks, it can potentially lower blood sugar, boost immunity, and fight fatigue among other proven health benefits.

This ingredient went through a popularity phase... so you'll find a lot of false and unsupported claims surrounding it. Ginseng can do a lot, but it's not linked to improved cardiovascular health or weight loss. And while it has a natural ability to combat fatigue (potentially keeping you energized without the crash that high sugar content can cause), there's little research into ginseng extracts specifically in energy drinks.

While ginseng is generally safe, without any health risks and adverse effects, we're not sure how much herbal supplements like this actually contribute to your energy via a drink or energy shot - especially when they already contain energy-boosting ingredients like caffeine.

Citric Acid

Citric acid, found naturally in citrus fruits, is a common ingredient in energy drinks. It serves as a natural preservative, boosts acidity, and enhances flavors, making your favorite energy drinks tastier and more refreshing (yep, it's in Zest energy drinks).

But citric acid does more than just improve the taste. There's evidence that it enhances the bioavailability of other nutrients in energy drinks, helping your body absorb them more effectively. This can be particularly beneficial when paired with dietary supplements.

While the Food and Drug Administration (FDA) considers citric acid safe, it’s always wise to be mindful of the overall sugar content and caffeine intake in your energy drinks. Citric acid may mask the sweetness of your energy drink, even though it contains an ungodly amount of sugar. Even popular options like Red Bull energy drink balance citric acid to improve both taste and nutritional uptake.

Sodium

Sodium is a mineral and an essential electrolyte found in many energy drinks. It helps maintain fluid balance, supports nerve function, and can enhance athletic performance. For young adults and athletes, a bit of sodium can be a game-changer, improving reaction time and overall performance.

As an electrolyte, sodium prevents dehydration and maintains proper muscle function. When you sweat, you lose sodium, making its presence in energy drinks important for replenishment during intense workouts.

However, balance is key. While some sodium is beneficial, too much can raise blood pressure and increase the risk of cardiovascular disease. It's important to monitor your energy drink consumption to make sure you're not overloading on sodium.

Other electrolytes that you might spot in energy drinks (or energizing electrolyte powders) include chloride, potassium, calcium, magnesium, and phosphate. Find a full list of key nutrients that you should look for in electrolyte powder and drinks in this guide.

Artificial Flavors

Finally, one ingredient you should absolutely avoid when consuming energy drinks is artificial flavoring.

Artificial flavoring is commonly found in energy drinks like Red Bull (which has both natural and artificial flavors), designed purely to enhance the taste. These chemical-based additives have no impact on energy levels, caffeine content, or physical performance. They simply make the beverage more palatable as you slurp it down.

Considering the effects of energy drinks are unrelated to the flavor, why not opt for natural flavorings instead? Natural ingredients can offer a better taste profile without adding unnecessary chemicals. When evaluating your energy drink consumption, looking for products with natural flavorings can be a healthier choice - or at least a more natural one.

At Zest, we choose natural flavors and non-GMO ingredients. It has no impact on the energy-boosting properties of our beverages, but it does make our drinks cleaner.

Is Energy Drink Consumption Safe?

The answer is quite simple: energy drinks are safe to consume in moderation, but too much caffeine and sugar can be a problem. It's essential to understand the potential health effects and safety concerns. First, let's define how much is safe to consume.

According to the Food and Drug Administration:

• Adults: a maximum of 400mg of caffeine per day for healthy adults.
• Pregnant Women: the limit drops to 200mg per day to avoid any potential health risks.

To put this into perspective, a Zest energy beverage contains up to 150mg of caffeine. A cup of coffee contains roughly 90mg. Soda, on the other hand, can have a caffeine content ranging from 20mg to 70mg depending on the brand and formula.

Consuming caffeine can actually have health benefits too. These can include:

• Increased alertness and concentration
• Enhanced physical performance
• Improved reaction times

There's also some evidence that caffeine may protect against diabetes. Studies have found that those who regularly drink coffee may have a lower risk of heart attack, meanwhile those who regularly drink green tea could be at a lower risk of stroke. Of course, this isn't just down to caffeine and these benefits might not translate to energy drink consumption.

There are also important adverse health effects of caffeine that you should know about, especially if you enjoy energy drinks excessively:

• Increased heart rate and blood pressure
• Insomnia and restlessness
• Potential for cardiovascular diseases if consumed excessively

Energy drinks often get a bad reputation due to misuse, especially among young adults. Excessive caffeine consumption or combining energy drinks with alcohol and other illicit substances can lead to serious adverse events. This misuse has resulted in numerous energy drink-related emergency room visits - the kind you might have read about in the news or on social media.

So, like anything, it's all about finding a balance and learning to consume energy drinks responsibly. Misuse can lead to health risks, but moderate consumption can be part of a healthy human diet without negatively affecting your health (and you can reap those energy-boosting benefits).

Clean Energy Drinks Exist!

Not all energy drinks are created equal. Clean energy drinks like Zest use tea extract to naturally boost caffeine levels, combined with focusing L-Theanine for a smoother energy experience. So, you can get your energy drink boost without all the nasty crap.
