Common Ingredients of Energy Drinks

Energy Drinks are the beverages that provide us the extra energy that we need for the completion of various tasks!

The ingredients of the drink might vary from each other giving it distinct benefits and qualities, however, the following are a few common ingredients found in almost every energy drink:


Caffeine, being the world’s most consumed psychoactive drug, is the main ingredient of almost every energy drink.

It is a natural stimulant, and hence it has certain effects on one’s brain. It can keep you wide awake if you want to wear off that unnecessary drowsiness.

When we drink caffeine, it reduces the action of adenosine by attaching itself to the receptors. As adenosine is responsible for making you drowsy so caffeine suppresses its effects.

However, this is not all, there are certain negative effects of caffeine on the brain. Caffeine can cause anxiety as it increases cortisol and adrenaline (Epinephrine). This anxiety and irritability in turn can make a person angry.

Moreover, too much caffeine ingestion can disturb your sleep pattern and you are likely to experience sleepless nights. Not sleeping can also cause you to become angry and moody.

Following are a few psychological and physical side effects of caffeine:

  • agitation

  • dizziness
  • increased heart rate
  • nausea
  • diarrhea
  • changes in mood

In order to avoid any kind of negative side effects of caffeine, you should try keeping your caffeine intake below 400 mg of caffeine.

Caffeine Dependency

When you consume too much caffeine, you become dependent on caffeine. The reason is that when you drink too much caffeine, so for a time being the caffeine molecule blocks the receptors of adenosine.

However, adenosine receptors increase later, and the same amount of caffeine is not enough to block the receptors, this increases your need to increase your caffeine intake and in this way, you become dependent on caffeine because the same amount of caffeine stops working on you.

In the same way, if you consume too many energy drinks having high dosages of caffeine, then you can become kind of addicted to them.

Caffeine Withdrawal

As the name suggests, caffeine withdrawal happens when you try quitting caffeine. You are likely to face some signs when you become dependent on caffeine.

Caffeine withdrawal symptoms can include insomnia, headaches, and stomach upset. For some people, the symptoms are mild and will subside in a few days.

For others, the withdrawal symptoms may be more severe and lead to withdrawal cravings. People who are sensitive to caffeine withdrawal may also experience anxiety and irritability.

Caffeine withdrawal symptoms can also make you extremely angry and annoyed.

A few symptoms of caffeine withdrawal can be:

  • Headaches.
  • Tiredness.
  • Difficulty concentrating.
  • Nausea.
  • Muscle pain.
  • Irritability.

The best way to avoid caffeine withdrawal symptoms is to reduce your caffeine dosage gradually rather than quitting it altogether.

Sucrose, sugar, white sugar, or table sugar is a granulated sweet crystalline molecule that we consume daily.

Consuming sugar does not have any other benefits than providing you a momentary energy burst which soon ends up in nothing but agitation, irritation, and anger.

Not only this, but then your body will demand more sugary food to elevate your mood again. However, this will only increase your body weight, nothing else.

B Vitamins

The B vitamins are water-soluble vitamins that the body requires, and are found naturally in food such as meat, eggs, and dairy.

They are also available as a supplement in tablet form and are necessary for healthy skin, hair, and nails, and for energy and cell growth — all of which are essential to a complete, healthy, and active life.

B vitamins are usually classified by the chemical elements they contain (B1, B2, B3, B6, folate, B12) and by the way they are found naturally or are made synthetically.

They also help the body in several other ways. Not only do they help provide energy to your body, but they also help keep your immune system strong, can promote longer life, and may help prevent some of the health problems that come with getting older.

Can Energy Drinks Make you Aggressive?

Energy drinks can cause you to become irritated and annoyed due to the hormone-disturbing ingredients present in them.

Caffeine, sugar, and Guarana altogether or separately can cause mood swings which include feeling angry and agitated.

When you get angry, your body’s fight or flight response is triggered. This increases your body’s levels of cortisol and adrenaline.

This can cause people to have more muscle tension, tend to breathe faster, and have increased heart rate and blood pressure. It makes their bodies more likely to engage in physical activity, which can include fighting, running, and kicking.

However, evidence shows that too much anger can cause short-term health problems, such as muscle tension, fatigue, headaches, and backaches.

Can Energy Drinks Make you Hungry?

Energy drinks can make you hungry as they are full of sugar and no fiber at all. You might feel full for a while, but soon you will end up being hungry.

The sugar present in energy drinks might increase your cravings for eating something sweet. This can even lead to overeating, so you might end up gaining weight.

  • It is true that energy drinks make you angry and can cause anxiety!
  • Ingredients such as caffeine, sugar, and Guarana can cause you to become angry and annoyed,
  • In order to save yourself from such symptoms and the negative outcome, choose an energy drink containing a lesser amount of such ingredients.
