What are the Side Effects of Red Bull?

In recent years, energy drinks have become increasingly popular, with Red Bull leading the pack. However, there is growing concern over the health risks associated with these drinks.

The combination of ingredients used in Red Bull can cause side effects, especially if consumed in large amounts (more than 2 cans per day) over a long period or when mixed with alcohol. Research suggests that all energy drinks, in general, can harm your health. They can be especially damaging to young people and children.

Red Bull contains high levels of caffeine and other stimulants, which can lead to increased heart rate and blood pressure. These effects can be especially dangerous for people with pre-existing heart conditions.

Red Bull has also been linked to several adverse reactions, including dizziness, nausea, chest pain, and even death. Whilst these cases are rare, they underscore the potential risks associated with energy drink consumption.

Limiting or avoiding Red Bull altogether is advisable, given the potential health risks. If you do choose to drink it, be sure to do so in moderation and always consult with your doctor first if you have any concerns about your health.

Instead of risking your health in the long run, have you thought about energy drink alternatives

Our recommended choice for a Red Bull alternative is just as effective, 100% plant-powered, and safe for long-term use as it has little to no side effects! Take advantage and save time by using a quick buy function.

Below, you will find a complete list of the possible Red Bull side effects and how they could affect you.

Take our quiz to see if you need to cut back on energy drinks due to side effects.

12 Red Bull Side Effects

1. Jitters

This is where you experience a sudden rush of intense energy which can make you feel a bit shaky. Your energy will then suddenly crash, which can feel quite unsettling. 

Drinking more than five cans daily would increase your risk of a caffeine overdose. Remember that you also receive caffeine from other foods and drinks, so it's important that Red Bull is consumed in moderation.

2. Migraines

Migraines can occur as a result of what's called a caffeine rebound. This is where your body gets so used to consuming certain levels of caffeine that withdrawing from it gives you a headache.

Therefore, regular drinkers of Red Bull are more likely to experience regular migraines as they depend more on caffeine.

3. Insomnia

Difficulty falling asleep and staying asleep can also be caused by too much caffeine intake. Regularly having a poor night's sleep will take its toll on your energy, mood, ability to function throughout the day, and overall health.

The later in the day you have caffeine, the more it will affect your sleep, so it's especially advised not to drink Red Bull in the evenings.

4. Excess Sugar

Red Bull contains a large amount of sugar to support its energy-boosting abilities - one regular-sized can of Red Bull contains the equivalent of nearly seven teaspoons of sugar. The 'easy sugar' supplied by energy drinks, i.e. refined sugar could harm cells, including brain cells.

Getting a big sugar rush from an energy drink will leave you feeling lethargic and even more tired afterwards once your blood sugar levels go down quickly. Excess sugar intake has also been linked to the increased risk of type 2 diabetes and may cause are damage to your teeth and kidneys.

5. Stress Reaction

When you feel like you need to have an energy drink, the chances are that you are under pressure and experiencing a stressful situation of some sort. You feel tired but pressured to perform well.

If the situation is mentally challenging, like studying for an exam or trying to squeeze in an essay just before a deadline,you will likely experience impaired memory as your body and brain focus on dealing with the perceived stress rather than cognitive functioning.

6. Interference with Neural Communication

When consuming excessive amounts of glucose in the form of refined sugars, neural communication gets disrupted. This could affect not only memory but also other cognitive functions, such as attention span.

If you are experiencing any combination of these side effects from regularly drinking Red Bull, we recommend trying Brainzyme® FOCUS PRO™ as a natural food supplement alternative to Red Bull.

7. Increased Heart Rate

Heart rate measures heartbeats per minute. Due to its caffeine content, Red Bull can increase your heart rate. Excess intake, especially in young people, has been linked to heart palpitations, abnormal heart rhythm and even heart attacks.

8. Increased Blood Pressure

Blood pressure refers to the blood moving through the body, and increased blood pressure is correlated with increased heart rate.

Several studies have shown that drinking a can of Red Bull significantly increases both blood pressure and heart rate within 90 minutes and for up to 24 hours after consumption.

9. Weight Gain 

As mentioned above, Red Bull contains a lot of sugar. Sugary drinks contain many calories and are associated with weight gain and obesity. Furthermore, the calories you consume in Red Bull are empty calories.

Your body receives no substantial nutritious benefit when drinking Red Bull and other energy drinks. Therefore, these calories could be easily cut out to make room for healthy and calorie-rich foods that will actually benefit your body.

10. Interference with Healthy Sleep Patterns

If you are working late or waking up after a short night's sleep and feel like you need an energy drink to get you going, the chances are that your body is telling you that you need more sleep.

Relying on energy drinks to feel awake and energised will potentially interfere with a healthy sleep pattern that would maybe be sufficient to make you feel that way in the first place.

11. Withdrawal Symptoms

Similarly, consuming drinks high in caffeine and high in sugar will increase your tolerance for them, so eventually, you will need to consume more and more to get the effects you're used to.This can lead to withdrawal symptoms if you're not getting your caffeine fix of the day. 

You might have experienced craving coffee in the morning, and many people start to suffer headaches if they don't get their morning cup.Or, you might feel nervous or shaky when you're not regularly consuming the energy or other caffeine drink you are used to.

12. High-Risk Behaviour

A side effect you may not have considered when it comes to energy drinks is that they may increase high-risk behaviour, especially when mixed with alcohol.

Caffeine can mask the effects of alcohol, making you feel less intoxicated even though you are still under the influence. This can lead to risky behaviour, such as drink-driving, or injuries.

Who Should Not Drink Red Bull?

As a popular energy drink, Red Bull is marketed to increase energy and focus, however, there are certain individuals who should not consume it.

Pregnant and breastfeeding women should avoid consuming Red Bull as it contains caffeine, which can pass through the placenta and into the breastmilk, potentially affecting the developing fetus or infant. Caffeine intake during pregnancy has been associated with an increased risk of miscarriage, low birth weight, and developmental delays.

Individuals with high blood pressure, heart conditions, or other cardiovascular issues should also avoid Red Bull. The caffeine and taurine in the drink can cause blood pressure to rise, putting additional strain on the heart.

Those with anxiety or panic disorders should also avoid Red Bull, as the caffeine can worsen symptoms. Individuals with diabetes should also avoid Red Bull as it contains high amounts of sugar, which can cause blood sugar levels to spike. 

It's also recommended that children and teenagers should avoid consuming Red Bull, as their bodies are still developing and can be more sensitive to the effects of caffeine. In addition, excessive consumption of energy drinks has been linked to behavioural problems, poor school performance, and a higher risk of addiction.

If you're not sure whether Red Bull is safe for you, it's best to consult a healthcare professional. They can advise you on whether the drink is safe for you to consume and recommend alternative options if necessary. 

Rather than risking your body’s health with how bad red bull can be, why not check out the best natural Red Bull Alternative?

Is It OK to Drink a Red Bull Every Day?

Overall, no not really. Unless you are willing to keep it simple and consume no more than 1-2 ounces daily. That way you can avoid the potential long-term effects of Red Bull. 

Red Bull does offer some 'healthier' choices, though they have their risks: they include artificial glucose. It is tempting to think that the sugar-free Red Bull could be a better alternative. However, diet drinks like this have been associated with phenomena such as performing worse on delayed gratification tasks.

It's important to keep in mind that energy drinks are not recommended as a replacement for a healthy diet and lifestyle. There are healthier alternatives to boost energy such as getting enough sleep, eating a balanced diet and regular exercise.

How to Reduce Energy Drink Consumption

Reducing energy drink consumption can be difficult, especially if you’re used to drinking them regularly. However, it’s important to be aware of the risks associated with these drinks and to make an effort to cut back. Here are a few tips to help you reduce your energy drink consumption:

First, be mindful of how much you drink. If you’re not paying attention, consuming more energy drinks is easier than you realise. Keep track of how much you’re drinking each day and week, then try to reduce the amount gradually.

Second, ensure you're drinking plenty of water throughout the day. This will help to keep you hydrated and prevent you from feeling as thirsty, which can lead to drinking more energy drinks.

Finally, find alternative energy sources. If you’re used to reaching for an energy drink when you need a pick-me-up, try taking a natural food supplement instead. These supplements can help you to get the energy you need without all of the risks associated with energy drinks.
