Can Energy Drinks Make You Ill? (Explained)

As energy drink consumption grows globally and in the United States, it is critical to examine the nutritional content and effects on the population’s health of these beverages.

Energy drinks with caffeine and other stimulants are designed to increase alertness quickly.

Many people use them as an afternoon pick-me-up instead of coffee. However, studies have shown that these drinks can be harmful to one’s overall health.

Energy drinks in moderation will never harm you and will provide you with the promised benefits.

Caffeine intoxication, vomiting, cardiac arrhythmias, seizures, and even death can result from excessive consumption of energy drinks in some people. In a nutshell, it can make you sick if you consume it excessively.

Continue reading to know specifically what ingredients make you ill in energy drinks, as well as their overall effect on human health.

What Are Energy Drinks?

Many people turn to energy drinks when they need a quick pick-me-up or a boost to get through the day. Energy drinks are frequently marketed as a cure for tiredness.

Energy drinks, as opposed to sports drinks, contain high levels of stimulants such as caffeine. These drinks have gained popularity due to their known stimulant effect, but they have harmful side effects.

Caffeine is frequently the main active ingredient in energy drinks. However, they frequently contain other ingredients that are said to have stimulant properties.

Energy drinks also contain the following active ingredients:

  1. Taurine
  2. Glucuronolactone
  3. B Vitamins
  4. Guarana
  5. Ginseng
  6. Sugar

Adults are thought to be safe if they consume energy drinks in moderate amounts. When energy drinks are mixed with alcohol or consumed in large quantities at once, side effects such as irregular heartbeats and nervousness can occur.

Ingredients In An Energy Drink That Can Make You Ill

Herbs, vitamins, and caffeine are frequently found in energy beverages. They assert that they will give you more energy and awaken you.

They definitely make you feel energized due to their stimulant properties but their overconsumption can simultaneously make you ill.

Let’s have a look at these ingredients that can end up making you feel ill if consumed excessively.


Your favorite desserts are loaded with sugar.

Your favorite energy drinks have a hefty amount of sugar. Monster, Rockstar, Red Bull, and others are among them.

The American Heart Association recommends that women consume no more than six teaspoons (or 25 grams) of added sugar per day, while men consume no more than nine teaspoons (36 grams).

The issue isn’t just our growing waistlines; it’s also that eating too much sugar can make us sick. Sugar consumption increases the risk of developing chronic illness over time.

These high-sugar energy drinks also contain a lot of empty calories, which can lead to high blood sugar, diabetes, and even dental problems.

Let’s have a look at the sugar content present in some of your favorite energy drinks.

Energy DrinksSugar Content
Rockstar (8 fl. oz)30g
Monster (8 fl. oz)27g
NOS (8 fl. oz)26g
Red Bull (8.4 fl. oz)27g

Why is sugar considered bad?


Taurine serves numerous functions in the body. It is unclear, however, why taurine is added to energy drinks.

The most common taurine dosage range is 500-3,000 mg per day. However, an EFSA report from 2012 suggests that up to 6,000 mg daily is safe.

Taurine has no known side effects when consumed in reasonable amounts by a healthy individual.

Although there were no direct problems with taurine supplements, energy drinks containing taurine and caffeine have been linked to the deaths of athletes in Europe.

As a result, several countries have banned or restricted the sale of taurine.


Excessive calories can lead to weight gain.

Calories are not harmful to your health. Your body requires calories to function properly. However, eating too many calories and not burning them off through activity can lead to weight gain.

Fat, protein, and carbohydrates, known as the three macronutrients, account for nearly all of a person’s daily calorie intake.

A calorie deficit diet ain’t healthy for the human body. The cells could become weak due to insufficient energy consumption, and your organs could eventually fail to perform basic functions.

Excess calorie intake not only causes weight gain but eating too many calories from certain sources can cause other health problems.

When these factors combine, they can lead to a cascade of problems that have a negative impact on your overall health and well-being.

In general, women should consume up to 2,000 calories per day, while men should consume up to 2,500. Some high-calorie containing energy drinks are:

Energy DrinksCalorie Content
AMP (16 fl. oz)220
Full Throttle (16 fl. oz)220
Monster (16 fl. oz)190
Rockstar (16 fl. oz)140
Red Bull (8.4 fl. oz)110
Energy drinks with high-calorie content.

Amino Acids

Some common amino acids included in energy drinks are L-carnitine, L-tyrosine, and L-theanine. All of these play an essential role in metabolism.

Their individual functions can be defined as:

Amino AcidsFunctions
L-carnitineL-carnitine is essential for energy production; it transports long-chain fatty acids into the mitochondria to be oxidized (“burned”) for energy production.
L-theanineThe e benefits of L-theanine include improved alertness, relaxation, and sleep.
L-tyrosineL-tyrosine is a non-essential amino acid that is required for the synthesis of neurotransmitters in the brain, which are essential for nerve conduction and mood stabilization.
Amino acids are present in energy drinks.

The human body can only consume a certain amount of amino acids before becoming ill. When your body ingests an inflated dose of amino acids, the subsequent effects might occur:

  1. Gastrointestinal distress
  2. Diarrhea
  3. Risk of gout
  4. Drop in blood pressure
  5. Abdominal pain

Can Caffeine Make You Ill?

Caffeine is a key ingredient in energy drinks. It is addictive and, in high doses, can be harmful. It can make you ill in many different ways.

Coffee beans are produced the most in Brazil.

Caffeine overdose can result in headaches, irritability, nervousness, and a rapid heart rate. Energy drinks contain more caffeine than is recommended for children and adolescents.

This means that just one or two energy drinks can easily push you over the caffeine limit.

Caffeine concentrations in energy drinks can also overwhelm your digestive tract.

Extreme consumption of energy drinks may lead to vomiting, nausea, and diarrhea. Other possible side effects of consuming too many energy drinks include insomnia, heart palpitations, tremors, excessive sweating, and chest pains.

For healthy individuals, the FDA has determined that 400mg per day—or about four or five cups of coffee—is a safe quantity to consume.

Can Energy Drinks Make You Ill?

Energy drinks are known to help you stay alert, improve your mood, increase cognitive function, and provide a short-term energy boost.

However, negative effects from this type of beverage are possible, especially if consumed in large quantities. Some of these negative effects may cause you to feel ill or sick.

Consuming too many calories or sugar can lead to weight gain, and weight gain can lead to health problems that make you feel ill.

While getting more B vitamins than the recommended dietary allowance is generally not a cause for concern, getting too much of certain B vitamins can cause unpleasant side effects and make you sick.

Too much vitamin B6, for example, especially amounts greater than 100 mg per day, can cause nerve damage.

Caffeine consumption in excess of 400mg per day may cause anxiety, irritability, difficulty sleeping, muscle tremors, and gastrointestinal upset. Some people, particularly pregnant women and children, may be more sensitive to caffeine’s negative effects than others.

Should You Give Up On Energy Drinks?

When it comes to energy drinks, my advice is to always proceed with caution and test your body’s tolerance to caffeine and sugar.

If you need a boost in the morning, a cup of black coffee is a better option. Even better, get up 30 minutes earlier and do some aerobic exercise.

If you start your day with a morning workout, you will most likely have more energy, stamina, and focus. Another great way to boost your energy is to go for a short brisk walk during lunch.

If you want to drink energy drinks, limit yourself to no more than one can per day. They will serve as a safe option for you if you have them on occasion.

Limit your consumption if you can’t live without them. Most importantly, pay attention to how they affect your body and discuss any concerns with your primary care doctor.
