ROCKSTAR Energy Drink Review - 6 Things You Need to Know

Rockstar Energy offers energy drinks in 20 different flavors, from Guava to Frozen Watermelon. The company claims that their drinks can provide energy boosts and increase alertness and even athletic performance. However, can they prove their bold assertion that their energy drinks can make people better at sports?

With few studies available on the subject, our research team wasn’t sure that Rockstar Energy drinks could provide a demonstrable effect on performance in a variety of sports. Our research team took the time and effort to find out if what they claimed was actually true. Here’s a summary of what they found.

ROCKSTAR Energy Drink can be purchased through their Official Site.

What is ROCKSTAR Energy Drink?

First of all, ROCKSTAR Energy Drink is available in all sorts of flavors and varieties. Some of which include original, sugar-free, punched, pure zero, lime freeze, boom energy, revolt, zero carb, and organic. The key ingredients in this beverage are taurine, caffeine, guarana seed, ginkgo biloba leaf, milk thistle, and some B vitamins. This canned drink is claimed to heighten energy levels, elevate focus/concentration and keep you going. It’s sold in 8.4, 12, 16, and 24 ounce cans, and it’s marketed at people with “active lifestyles.”

ROCKSTAR Energy Drink has been available since 2001. It’s sold in common drugstores, supermarkets and gas stations. There are more than 20 different flavors to select from. Furthermore, it is manufactured in the United States, but read on…

Unpleasant Taste – “Concerning?”

The initial concern we have is the taste. According to our Research Editor, “Many customers have complained about the actual flavor of ROCKSTAR Energy Drink. This could be a real problem.”

One person reported, “ROCKSTAR Energy Drink has a serious chemical taste. Not pleasing to my palate. No thanks.”

However, some people do enjoy the flavor of this energy beverage. One customer commented, “Tastes better than Monster. Curious to try some of the other varieties.”

Another posted, “Not as good as Red Bull, but does the trick.”

The current flavors for ROCKSTAR Energy include:

  • Fruit Punch
  • Silver Ice
  • Punched
  • Watermelon
  • Grape
  • Mandarin Orange
  • Tangerine, Mango, Guava, Strawberry
  • Lemonade
  • Cotton Candy
  • Super Sours Green Apple
  • Peach + Iced Tea
  • Kiwi Strawberry
  • Blue Raz
  • Marshmallow
  • Whipped Strawberry
  • Whipped Orange
  • Island Fruit
  • Killer Grape
  • Killer Black Cherry
  • Killer Citrus
  • Pina Colada
  • Lime Freeze
Side Effects

Side Effects – “Yikes”

Another issue we have is with ROCKSTAR Energy Drink side effects. Some people have reported dizziness, heart palpitations, nausea, headache, upset stomach, jitteriness and nervousness. In fact, one user stated, “Gives me shaky hands and fast heartbeat. Not to mention a terrible crash later on.”

But, a different customer had this to say, “Gives me a serious boost. Not sure about some of the ROCKSTAR Energy Drink ingredients like Acesulfame, though.”

“Wakes you up in the morning. That’s for sure,” mentioned another.

Our research has revealed that if there’s a specific aspect of an drink or workout supplement that is especially burdensome (unpleasant flavor, side effects, high price) the chances of real results for the long term are slim. In other words, if ROCKSTAR Energy Drink does in fact taste bad to a lot of people, this could be a deal breaker.


ROCKSTAR Energy Drink was sued in 2013, according to NBC. After a man consumed 4 of the energy drinks in a 6 hour period, the user suffered a heart attack. The lawsuit claims the risks were not clearly communicated.


The Science – “Is There Any?”

Sadly, we did not pinpoint any documented science that supports ROCKSTAR Energy Drink and it’s claims. However, this beverage does contain some caffeine and amino acids to help boost energy levels and improve alertness. On the other hand, it’s unlikely to increase muscle strength. At DietSpotlight, we prefer to see some actual studies that support the product we’re reviewing.

What Users Are Saying

What Users Are Saying

“I have been a long time drinker of Rockstar energy drink. The taste is delicious and the effects are long lasting.”

“Taste great yet with the large amount of caffeine, there is a huge rebound fatigue that sets in shortly after. Also it’s interesting that you can buy these for $31 one day and a month later they are $39, then $45 the following day??? No thanks. Smart n Final has them for a lower price overall.”

“Thought I would like these since I like watermelon, tastes kinda like watermelon but it not a very strong taste. Probably won’t buy again since I didn’t care much for them.”

Bottom Line

The Bottom Line – Does ROCKSTAR Energy Drink Work?

So, should you race out to the store and buy ROCKSTAR Energy Drink? Well, we like that this beverage is available in many different varieties. It’s also nice to see that this product is made in the USA. But, we have some concerns about this drink because it’s not backed by any published research. Furthermore, we’re leery of the unpleasant taste and side effects that some customers have reported.

If your goal is to increase metabolism and improve weight-loss results, then we recommend you select a product that’s supported by documented research.

Among the best products we’ve seen this year is one called Noom. There is substantial clinical support showing more people lose weight and keep it off. What really thrills us about Noom is the personal touches like human coaching and custom meal plans.

The makers of Noom are so excited about their product they’re offering every Dietspotlight reader a free trial.

ROCKSTAR Energy Drink

What is in Rockstar Recovery?

These drinks are intended by Rockstar Energy to be a fusion of Hydration and Energy Drinks. They come in both lemonade and orange flavors. They are noncarbonated and include very little juice. They’re sweetened with artificial sweeteners. I’ve never encountered a well-done lemonade flavored energy drink but will reserve my judgment until I’ve given it a try.

How much caffeine is in a Rockstar?

In many locations, Rockstar is only sold in one size. These cans include about 160mg of caffeine each. Rockstar Energy offers consumers two separate sized cans of the drink in the United States. There is a 16oz option and 24oz option. In the popular 24oz can there are a shocking 240mg of caffeine.

What are the ingredients of Rockstar energy drink?

These are followed by guarana seed extract, Vitamin C, caramel coloring, two types of preservatives, caffeine, niacinamide, inositol, l-carnitine, and milk thistle extract.

What are the side effects of Rockstar energy drinks?

Ingesting too much of these delicious drinks can lead to several negative side effects, depending on how sensitive you are to caffeine. Some drinkers experience merely diarrhea, more frequent urination, nervousnes, and nausea. Others fall victim to dizziness, anxiety, panic attacks, increased blood pressure, heart palpitations, and jitters. Side effects and their severity vary with each individual.

Do Rock Star energy drinks really work?

All dieters fear that they may experience decreased energy with their lifestyle changes. Choosing an energy drink, particularly an inexpensive one like Rockstar, is often seen as an option to negate those concerns. However, energy drinks, in general, have been in the forefront of the news in recent years in light of potentially dangerous ingredients. Some ingredients in Rockstar energy drinks do have the potential to be unsafe.

  • 22 years old can take it?
    al quevedo

    I saw my neighbor give her 22 month old son a gulp of ROCKSTAR from the can. should i tell her that the childs system can be damaged or negatively affected?

    • John

      No, you should mind your own business. Highly doubt the child will be scarred for life after a gulp of drink…. don’t be a nosey idiot. Focus on your own business…

      • Jerry Vearrier

        If you know something is going to hard or harm someone, yes you have an Obligation to say something. Bad things happen because good people say nothing. The is the biggest problem today.

    • Your Name

      That’s just moronic. Why would someone poison their child with this stuff? Tell your neighbor the ingredients and effects it could have on their child.
