Energy drinks are great for studying as they have ingredients that improve mental performance.

For more insight, keep going.

Why Do People Drink Energy Drinks?

People drink energy drinks because of the many benefits the drinks claim to have. Benefits like replenishing energy, and improving physical and mental performance. Also, some just like the taste.

Busy people
People get easily tired in this fast-paced era

In a fast-paced society where it’s becoming more of a norm to prioritize work and studies rather than health in order to not get left behind, energy drinks are a popular go-to for energy boosts.

It’s important for people to keep their energy up while they buzz around like the busy bee they are and not get tired.

Energy drinks serve as a lifeline for others to alleviate their tiredness and vitalize focus and energy for the rest of their day.

Do Energy Drinks Help You Focus?

It has been proven in studies that energy drinks like Red Bull can boost cognitive performance, thus better focus and concentration, so as long as you drink a healthy amount, energy drinks can help you focus.

When studying, it’s vital to keep your mind on one thing, specifically one topic, so you don’t end up overwhelming yourself.

Energy drinks are filled with ingredients like caffeine and taurine which can be helpful in keeping your brain on the road to focus on what needs to be done.

However, you don’t want to overdo it and end up getting the negative side effects of energy drinks like anxiety and jitters, both of which can hinder your studies, so you might wanna pace yourself and drink a reasonable amount.

If you’re interested in energy drinks that are least likely to give you the jitters, here’s an article I wrote listing the drinks that I think won’t give you that side effect. Check it out!  

Do Energy Drinks Make You Smarter?

Energy drinks can improve your cognitive function thus making you ‘smarter’, however, this does not mean drinking energy drinks will turn you into Albert Einstein.

There are certain ingredients in these drinks that help your brain function but only to an extent. This does not mean that if you take an energy drink before a test, the answers of the universe start to present themselves to you and you miraculously ace said test.

It’s important to drink these drinks moderately while studying. Drink responsibly and stay in school, kids.  

Do Energy Drinks Help With Studying?

Energy drinks can help you with studying by improving your focus and concentration.

Energy drinks can help you study better by increasing your attention and concentration.

The caffeine found in energy drinks stimulates your nervous system, which then gives you a boost in your energy levels and mental performance as long as you get the dosage right.

Always remember that the approved caffeine limit by the FDA is 400mg. Anything above that might be detrimental to your health.

Studies have proved that caffeine helps students improve brain function like memory, concentration, and reaction time, while also reducing mental fatigue.

Energy drinks might be a great pick-me-up when you’re pulling an all-nighter to study, but that doesn’t mean you should be dependent only on energy drinks and forgetting about other factors to enhance your mental performance better.

To know more about energy drinks, here’s a video by

Other factors that can greatly enhance your concentration include:

  • Getting a decent amount of sleep
  • Taking breaks
  • Eating a balanced and healthy diet
  • Trying meditation
  • Eliminating distractions
  • Using time blocks

Energy Drinks Notable Ingredients

Now that we’ve gone over energy drinks and where they are used, let’s go over the common ingredients found in energy drinks and how each helps and contributes to the revitalization and boosting of energy.


Caffeine is the star ingredient of most energy drinks. Why? Because it has the ability to prompt your nerves, particularly binding your adenosine receptors that reduces your drowsiness and makes you feel more awake and alert.

Coffee glass
Caffeine is mostly found in coffees, green teas, beans or seeds, and even chocolates

The caffeine molecules act as a stimulant that affects adenosine (a molecule produced by humans with various functions in the body).

As caffeine binds to adenosine receptors, it actually makes the neurons fire more. The pituary glands on the brain, which regulates the release of many hormones, takes this increase in in activity as a signal to release hormones to produce adrenaline or epinephrine. The adrenaline release leads to other common effects associated with caffeine, such as the heart beating faster or feeling excited.


That being said, caffeine can be beneficial from time to time when it needs to be. But overconsumption of caffeine is not good as how its benefits sound.

The FDA approved a daily limit intake of 400mg of caffeine. And going over the limit may cause you some adverse effects, especially if you have a low caffeine tolerance.

Some of these are:

  • Anxiety
  • Jitters
  • Inability to focus
  • Gastrointestinal discomfort
  • Insomnia
  • Irritability 
  • Heart palpitations

As such, it’s best to be mindful of your overall caffeine intake and avoid having too many caffeinated drinks in a short period of time.


Sugar is also common in energy drinks. But some energy drinks nowadays use artificial sweeteners as they are much safer to use while it provides no caloric components.

Too much sugar may potentially harm your overall health

The AHA recommends 9 teaspoons or 36 grams for men per day and 6 teaspoons or 25 grams for women per day.

Anything more than that might give your health adverse effects such as:

  • High Blood Sugar
  • Acne
  • Irritability
  • Increased Blood Pressure
  • Type 2 Diabetes
  • Heart Problems
  • Weight gain/obesity


An amino acid, taurine, has a long list of potential benefits that come along with it.

Because of its cognitive function advantages, taurine is increasingly being included in the composition of energy beverages.

Taurine is plenty in areas like the brain, heart, and platelets, and can be found in foods like meat, fish, and eggs. Despite the many rumors floating around about where the taurine in energy drinks is derived, it is actually synthetically sourced.

Among the potential benefits of taurine include:

  • Promoting metabolism
  • Protecting the eyes
  • Protecting the heart
  • Improved exercise performance

Final Thoughts

Studying takes a lot of mental and physical energy, which is why it is necessary to have an energy booster by your side when you’re preparing for an exam or simply just reviewing your notes.

Energy drinks can help with studying but if taken irresponsibly, they might bring negative effects to your health that may result in poor academic performance, so while energy drinks can be your best buds on a night nose-deep in textbooks, they could also be your worst enemy if you decide to abuse it.

Be wary of its contents, take note of the advised limits by health officials, and pace yourself when drinking energy drinks. It’s good to be awake for the study, but it’d be bad if you ended up crashing during the actual day of the exam.

I hope you find this article helpful! Happy studying and good luck!
