Best Energy Drinks Before Exam (Revealed)

All those all-nighters and continuous studying before exams can make you tired and exhausted.

Energy drinks can be quite helpful for all those all-nighters and late-night studies during your exams. Drinking an energy drink before studying can help you concentrate and make your mind more alert.

However, they are so many energy drinks brands available in the market that can confuse you. You might wonder which energy drink you should go for and which one will suit you better.

In this article, I’ll help you out in deciding which energy drink is best for you and what you should look for in an energy drink.

Let’s begin.

What Are The Ingredients In Energy Drinks?


Caffeine is one of the main ingredients in an energy drink, and it’s the ingredient that can help you with your focus and make you more alert.

When it comes to caffeine content, every energy drink has different amounts of caffeine. You’re free to choose which energy drink you want to go for, depending on your caffeine tolerance and your caffeine metabolism.

Besides increasing your concentration, caffeine also offers the following health benefits:

  • Enhance physical performance
  • Boosy focus
  • Increase energy
  • Lower the risk of type 2 diabetes
  • Improve memory
  • Improve reaction time
  • Reduce fatigue
  • Increase alertness

According to FDA, an adult shouldn’t have more than 400mg of caffeine in a single day. This is very important for students to follow this recommendation since consuming more caffeine than this can lead to the following health problems:

  • Dizziness
  • Anxiety
  • Dehydration
  • Addiction
  • Insomnia
  • High blood pressure
  • Irregular heart rate

Even though caffeine is great for increasing your focus which can help during your exams, you should still consume caffeine in moderation to avoid any adverse effects.

Here’s a video discussing how caffeine affects your brain:

Sugar is another common ingredient found in most energy drinks.

Sugar is also great for boosting your energy and can provide an immediate burst of energy, but it’s not completely healthy to consume.

For your reference, the American Heart Association (AHA) recommends a maximum daily sugar intake of 37.5g for men and 25g for women.

Consuming sugar more than recommended maximum intake of sugar can lead to the following health issues:

  • Tooth decay
  • Diabetes
  • Obesity
  • Acne
  • Wrinkles
  • Low energy
  • Depression
  • Weight gain

I think it’s better to go for sugar-free versions of energy drinks.

But if you still want to consume an energy drink with sugar, then go for an energy drink with a minimum amount of sugar to avoid side effects caused by sugar consumption.

Can Energy Drinks Help You In Studying Before Exams?

Energy drinks can help you study before your exams if you drink them responsibly.

Energy drinks have caffeine as the primary ingredient that helps you focus and reduces your mental fatigue and tiredness, and the added ingredient of Guarana in some drinks can also aid you.

The combination of these ingredients is amazing for you and can help you with your memory. They can increase your alertness and make your brain function more efficiently.

Apart from that, energy drinks also contain some other ingredients, such as taurine, ginseng, B vitamins, and carnitine.

All of these ingredients are combined to help you with your stress level during your exams, and they can reduce your anxiety to make you feel more relaxed.

So if you’re thinking of pulling an all-nighter, then energy drinks can help. However, energy drinks alone won’t help you 100% with your energy and focus.

You need to have a proper sleep and an excellent diet to perform better at your exams.

What Food Can Improve You Concentration?

Apart from energy drinks, there are other foods as well that can improve your focus and concentration. Here’s a list of food that can improve your concentration.


Blueberries are known to boost your focus up to 5 hours. It’s an antioxidant and can help you with your blood flow and oxygen to your brain.

They will make you feel full for a more extended time and will save you from getting distracted because of your hunger pangs during your task.

Dark Chocolate

Dark chocolate contains a small amount of caffeine, and caffeine is known to increase your alertness and improve the functions of your brain.

So eating dark chocolate can help you concentrate and boost your focus instantly.

Flax Seeds and Nuts

Flax seeds and nuts are full of important nutrients that are great for your brain health. Flax seeds are high in fiber, magnesium, and B vitamin, so it’s great for improving your thinking skills and mental clarity while helping with weight loss as well.

You can drink a can of Red Bull before an exam to boost your focus. But since the original version of Red Bull contains a lot of sugar, I recommend you go for a sugar-free version of Red Bull.
