Here at DietSpotlight, we created a comprehensive review, examining the side effects, ingredients, clinical studies and overall customer-service quality.

What is Red Bull Energy Drink?

Firstly, Red Bull Energy Drink is marketed as an energy booster in a can. It’s available in a few different varieties, such as original, sugar-free, total zero and some alternate flavors. You can find this product in most supermarkets, gas stations and drugstores. It’s said to vitalize the body and mind and improve focus. You are encouraged to drink it while playing sports, on the road, staying up late or listening to long lectures. It contains ingredients such as caffeine, taurine, B vitamins, sugar and alpine spring water.

The Red Bull company is Austrian, and it’s been around since 1987. This beverage is sold all over the world, and it contains no cholesterol. Furthermore, it provides some vitamins and minerals. Also, this energy drink is fairly low in calories (169 per can), but read on…

High Sugar Content – “Will It Cause Weight Gain?”

The first issue we have is with Red Bull Energy Drink ingredients. “This canned beverage contains both sucrose and glucose, which provides 37 grams of sugar per serving. This may cause weight gain if consumed regularly,” says our Research Editor. “However, there are sugar-free options.”

One customer reported, “It’s way too sweet. Same as drinking soda, which also has sugar and caffeine in it.”

On the other hand, a different user said, “I like this stuff for late study sessions. Keeps me up. That’s what I need.”

“Will give you a slight buzz, similar to coffee. Maybe a bit more because of all the sugar,” mentioned anther person.

Side Effects – “Watch Out”

Another concern we have is Red Bull Energy Drink side effects. Some people have reported jitteriness, rapid heartbeat, insomnia, anxiety, nervousness, headache and nausea. In fact, one customer stated, “Makes me quite jittery. Also, can’t get to sleep if I drink this in the afternoon.”

But, a different user had this to say, “Comparable to coffee with sugar. Has a definite stimulant effect, but I can deal.”

Another posted, “Will give you a boost. If you’re not into coffee and soda, this is a decent alternative.”

The research we’ve done has shown if there’s some specific part of an energy drink or supplement that is quite difficult or bothersome (high sugar content, side effects, steep price) the chances of real results for the long term are slim. Therefore, if Red Bull Energy Drink does in fact lead to unwanted reactions in a lot of people, this could be a real problem.

The Science – “Is There Any?”

While we did not pinpoint any clinical research on Red Bull Energy Drink, this beverage may help give you a boost. After all, it does contain caffeine, which is a stimulant. On the other hand, the buzz it gives you is unlikely to last long. Furthermore, it may lead to some side effects, including an unpleasant crash later on.

What Users Are Saying

"”Red Bull is by far the best energy drink I’ve consumed and I have tried multiple. It helps get work done late at night and the taste is great as long as it’s refrigerated.”"

"”It would get five stars if it weren’t so addictive. It also makes me more edgy than coffee.”"

"”Lousy, expensive; in a word YUK!!!. Want a zoom or pick me up? Drink coffee or tea!”"

The Bottom Line – Does Red Bull Energy Drink Work?

So, should you run out to the store and buy Red Bull Energy Drink? Well, first off, we like that this beverage contains some B vitamins. It’s also nice to see that it’s easy to purchase in most grocery and convenient stores. But, we have some reservations about this product because some varieties contain a lot of sugar, which can lead to weight gain. Also, we’re concerned about the side effects that some users experience.

If your goal is to increase physical performance, build lean muscle mass and improve energy levels, we recommend you choose a product that does not cause any harmful side effects, is not loaded down with sugar and is easy to take anywhere.

Among the best products we’ve seen this year is one called Dietspotlight Burn. This unique formula offers four important ingredients, which are shown to help elevate metabolism and support weight-loss. We have not found any discouraging user comments, but the reviews posted on the web indicate people are seeing solid results.

The makers of Dietspotlight Burn are so enthusiastic about their product they’re offering every customer a Special Trial Offer.

What You Should Know

Red Bull is an energy drink that currently dominates the U.S. market and is sold around the world. Red Bull claims to boost metabolism, improve performance, increase concentration and reaction speed, and increase endurance. Red Bull is used mainly as a performance enhancer but is frequently used by those trying to lose weight as the caffeine provides a thermogenic benefit. Thermogenesis is a process in the body that speeds up metabolism and burns adipose (fat) tissue. The stimulant effect of the caffeine also increases activity levels which help to burn calories. Red Bull has had a checkered history since it was first produced in 1997 on a large scale. It has been incorrectly condemned for its high caffeine content which is actually about the same as the average cup of coffee. Small scale clinical studies have been performed on Red Bull and have had mixed results. Some of the studies link the product to heart disease and high blood pressure but there have been no definitive results. Red Bull has a different formulation in different parts of the world. The ingredient list below relates to the North American version of the product. Red Bull has also recently developed Red Bull Cola which bills itself as all natural, containing no synthetic preservatives or flavorings.


Sucrose, glucose, Inositol, Taurine, Glucuronolactone, niacin, Vitamin B6, Pantothenic acid, Vitamin B12, and caffeine.

Product Features

Red Bull's stimulant effect comes from more than just its caffeine content. Taurine is a natural amino acid found in the body. It is excreted under conditions of extreme physical activity and stress and is not replaced quickly. The B group vitamins in Red Bull also help to boost the body's metabolic rate and improve concentration and focus. According to the company's website, Red Bull should be consumed in the same moderation as other caffeinated drinks like coffee. Each serving contains 80 mg. of caffeine, approximately the same as coffee and about the same as two cola beverages.


  • Provides short term energy and concentration.
  • Portable and easy to consume.


  • Not thoroughly clinically tested as yet.
  • Expensive compared to other caffeinated beverages.
  • May not provide enough caffeine to produce weight loss.


Red Bull Energy Drink is definitely one of the hot new beverage trends. The combination of caffeine, B vitamins and Taurine may be able to boost metabolism. However, if your main goal is weight loss, there are many products on the market today that contain caffeine as well as other clinically-proven ingredients that help to burn fat and accelerate weight loss.

  • Just curious...

    How was Red Bull invented?

    • Summer (Editor)

      Hi Sasha. Dietrich Mateschitz, of Austria, was inspired by an energy drink named Krating Daeng, which was developed and sold in Thailand. He modified the ingredients to be more suitable to the western palate. On April 1, 1987, Red Bull Energy Drink was sold for the first time in Austria, its home market.

  • Stop the selling of all energy drinks until they are proven safe
    Dave (Verified User)

    Countries have banned red bull,Cities have banned energy drinks as well.I took a sip of red bull and got sick,and think they should be banned,and a minimum age of 19 be required.A boy died from drinking one years ago on an empty stomach.Other kids mix it with alcohol.Since this product and others have and do cause health effects,it is a wonder that any company that has an iota of consciousness over the greed of money,continues to sell the product and deny it’s negative effects.

  •  Rate it One Star
    Vickie (Verified User)

    I rate this ONE star because it demands “something”. Otherwise I would rate it as NOTHING! My sister had one with GLASS SHARDS and is getting ZERO response thus far from the company. I WILL be following up with the company, as will she and when I get the batch number from her, I will share. This needs to not only be recalled, but please… STOP POISONING YOUR BODIES WITH THIS! For the big corporations, it’s all about the almighty dollar. NOT about your health. That’s all they care about.

  •  Loved the product.
    Jen (Verified User)

    I love Red Bull. I started drinking it in 2009 when I worked the night shift…it was a life saver. My problem is I have no appetite for the last year. I have to force myself to eat and I instantly get full even if I still feel hungry…so I have examined every aspect of my life to try & figure out why the extreme weight loss. My only conclusion is that its the Red Bull. Some would be happy to drop all this weight but I have no shape anymore. I love how this drink tastes & I consume 16-32oz a day. Any thoughts on this?

  •  It gives energy but don't overdo
    danny (Verified User)

    Redbull can make you very sore for like 2-4 days, if you play sports to give you energy. I always take redbull to give me energy to play sports but the side effect is that it can make you very sore if you over do what your body can’t handle

  •  No breakouts
    janny (Verified User)

    I tried the Red Bull, regular, drink and love the taste. I just hope there’s no side effect from consuming too much. I am not a big soda nor coffee drinker, but am hooked on this Red B for it’s crisp and refreshing taste. I seem to be reaching for one everyday and I sleep soundly as usual and don’t feel any pumped up energy. I usually have one with meals or between meals. I am in my 40’s.

  • addicted
    Crimson (Verified User)
