⚡ Energy drinks vs. sports drinks: what's the difference?
People often confuse sports drinks and energy drinks—the category Red Bull belongs to. While sports drinks are designed to support physical activity by providing water, sugar, vitamins, and minerals, energy drinks are too sugary and not hydrating enough to be used for sports.
In fact, the term energy drink mainly refers to drinks with stimulating properties, not truly energizing ones. The famous Red Bull slogan “gives you wings” isn’t about the energy you’d get for sports, but about the stimulant effect of the caffeine in your can!
📚 The story of a controversial energy drink
Where does Red Bull Energy Drink come from? If you didn’t know, it’s an energy drink marketed by the Austrian brand Red Bull, inspired by a sweet Thai beverage with taurine and caffeine called “Krating Daeng,” which literally means “Red Bull.”
Since its creation in 1987, the famous energy drink has been controversial: some countries even banned it as a precaution. The classic recipe was even banned in France from 1996 to 2008. Before that, the version sold in France was an alternative made with arginine.
The brand itself leans into the “rebellious,” “extreme,” and stimulating side of its flagship drink, highlighting its exciting effects to push yourself further. It loves to insert itself into the world of sports and e-sports to associate with peak performance.
And its success, fueled by massive marketing, inspired legions of competitors: energy drinks have flooded supermarket shelves.
🧪 Red Bull ingredients: a soda, not a miracle formula
So, what exactly is Red Bull and what gives it that “kick” effect? Let’s look at the ingredients of a 250 ml can of Red Bull Energy Drink:
- ☕️ 80 mg of caffeine, the same amount as a double espresso (40 ml).
- 🐂 1000 mg of taurine, an amino acid naturally present in the human body and protein-rich foods.
- 🎂 27.5 g of sugar, equivalent to 5.5 sugar cubes per can. Some versions replace sugar with sweeteners.
- 🧪 600 mg of glucuronolactone, a chemical compound naturally produced in the human liver from glucose metabolism. Used as a stimulant, but suspected to be harmful to kidneys in high doses.
- 🜛 B vitamins: 20 mg vitamin B3 (niacin), 5 mg vitamin B5 (pantothenic acid), 5 mg vitamin B6, 1.5 mg vitamin B2, 0.05 mg vitamin B12. One can of Red Bull covers the recommended daily intake for B2, B3, B5. With two cans, you exceed the RDI for B6 and B12 as well. These needs can easily be met through a balanced diet, no need to overdo it.
- 🧬 20 mg nicotinic acid: a form of vitamin B3. Your liver already produces it naturally, so no dietary intake is strictly necessary. Safety limit is 33 mg/day. According to VIDAL, high doses may cause flushing, digestive issues, headaches, increased risk of diabetes, or liver damage.
- 🌈 Other ingredients like colorings, flavors, and acidity regulators.
In short, it’s basically a soda, with the only difference being added B vitamins and taurine. And the effects—both good and bad—of taurine are still not fully understood.
🐮 Can taurine pose a health risk? Let’s break it down
Besides the high sugar content, the ingredient that sparks debate is mostly taurine. It’s a neurotransmitter involved in heart and muscle activity.
While Red Bull highlights that it’s naturally found in the human body and food, despite its stimulating effect, high doses may have side effects.
In medicine, taurine has several observed uses as a supplement, but never through energy drink consumption:
- Reducing LDL cholesterol (“bad” cholesterol)
- Increasing HDL cholesterol (“good” cholesterol)
- Detoxifying the liver, particularly by improving fat digestion
- Boosting vitality and performance
- Lowering blood pressure
- Regulating heart rhythm
- Reducing anxiety
However, research on taurine has been done using supplements with different concentrations than Red Bull and other energy drinks. No studies have specifically examined taurine in energy drinks; we just know it’s there, and maybe it does something, maybe not.
💡 Fun fact: Taurine is a so-called non-essential amino acid, meaning your body can synthesize it (scientific word: endogenous compound—now you can sound smart at parties). So you don’t need extra taurine in your diet, especially since excess is eliminated via the kidneys, adding extra workload.
So don’t count on Red Bull or its competitors to improve your athletic performance, focus while studying, or gaming reflexes: energy drinks have no proven effect beyond their caffeine content.
☢️ What Are the Risks and Side Effects of Overconsumption?
Beyond a certain dose, energy drinks can have side effects, some of which are still being studied:
- Increased risk of diabetes and obesity due to their high sugar content
- Digestive issues
- Thyroid dysfunctions
- Cardiovascular problems: chest pain, rapid heartbeat, high blood pressure
- Neurological side effects: irritability, tremors, anxiety, seizures
Since 2008, the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) has implemented a nutrivigilance system to report and track adverse effects of energy drinks. To date, more than 200 cases have been reported.
These symptoms usually appear when consumption is too high and too frequent. And it’s not just one ingredient at fault: the combination of high sugar, caffeine, and other stimulants can snowball and potentially pose a long-term health risk.
💡 FYI: A recent systematic review (The Effects of Energy Drinks on the Cardiovascular System: A Systematic Review, 2025) covering multiple studies confirms that energy drink consumption is associated with increased heart rate, blood pressure, and some ECG changes, which may pose an increased risk for sensitive individuals or with excessive consumption.
❤️🩹 Our Tips for Drinking Energy Drinks Responsibly
At the end of the day, energy drinks are like everything else: moderation is key! One now and then is fine, but more than that… watch out.
250 ml of the famous Red Bull contain as much caffeine as some cups of coffee, but also more than 5 sugar cubes and a dose of stimulants close to the daily limit. Even just to sleep better at night, it’s recommended to limit your caffeine intake.
Moreover, mixing these energy drinks with alcohol in popular cocktails among young people can also be dangerous for your health. This combo may lead to side effects such as nervous system issues and increased blood pressure. Alcohol danger + energy drink danger = FBI, bad idea!
Given these risks, health authorities have issued guidelines and contraindications for energy drink consumption:
- 🤾 Avoid consuming them before or during physical activity (prefer water or a sports drink instead)
- 🥃 Do not mix with alcohol
- 🚫 Avoid if you belong to "at-risk" groups: children, teens, pregnant or breastfeeding women, or anyone with a history of cardiovascular, neurological, liver, kidney, or psychiatric issues.
💡 FYI: Since 2008, the Ministry of Health has banned energy drink consumption in elementary and secondary schools.
🥤 Bottom Line – Energy Drinks: Sodas, Not Magic Potions
What Do Energy Drinks Contain?
The clever marketing of energy drinks claims they give you energy. In reality, they are basically sodas that rely on a hefty dose of caffeine to give you a kick in the pants.
They mainly contain sugar, B vitamins, caffeine, and taurine. If you ask us, they belong in the soda category.
Do Energy Drinks Really Improve Focus and Performance?
Energy drinks have no proven effect on concentration or energy levels. They are also too sugary to be intended for sports. High doses could even pose health risks.
So no, sorry to disappoint, Red Bull won’t really give you wings (even if the ads are pretty fun).
Do Energy Drinks Affect Heart and Health?
Current studies show no serious effects in healthy adults when consumed in moderation.
However, the caffeine and taurine in energy drinks can temporarily increase heart rate and blood pressure, especially with high consumption or in sensitive individuals. It is recommended to limit to one can per day and avoid consumption by youth, pregnant women, or people with heart problems.
What Are the Side Effects of Red Bull Consumption?
Excessive or regular Red Bull consumption may cause:
- Sleep disturbances and nervousness (due to caffeine)
- Tremors, anxiety, or restlessness in sensitive individuals
- Temporary increases in blood pressure and heart rate
- Digestive issues or abdominal discomfort in some cases
- Risky interactions with alcohol, as the drink can mask the feeling of intoxication
➡️ In summary, in moderate doses, Red Bull is generally not dangerous, but overconsumption or consumption by sensitive populations can cause side effects.
Recommended Dose – How to Drink Red Bull Safely
Due to potential side effects and contraindications, it’s best to consume it in moderation. Like any soda, an occasional Red Bull won’t harm you, but avoid it if you’re in an at-risk group.
Finally, Red Bull and other energy drinks are popular as mixers, but it is strongly recommended not to mix them with alcohol. Forget the Jagerbomb or vodka-Red Bull.
