With unicorn products that are much popular right now, you’ll be surprised with the all-new Rockstar TMGS the four fruits drink ~ Tangerine, Mango, Guava, as well as Strawberry. It is a pink-colored energy drink that comes in a rainbow-colored can. A single can contains the 240 milligrams of caffeine, which keeps me focused as well as weird.


Rockstar energy drink offers you 7 unique flavors from which you can choose from:

  1. Punched
  2. Blue Ice
  3. Silver Ice
  4. Mango Orange Passion Fruit
  5. Watermelon
  6. Mandarin Orange
  7. Grape


Well, this energy drink comes in 6 different flavors, but the flavors which I like the most are Silver Ice and Punched. Both of them are tasty, and you can consume it easily.

The Silver Ice is a mix between Squirt Soda and Fresca. However, it is not that sweet as Squirt Soda actually taste but sweeter than Fresca. The thing which you love the most is the crisp flavor of grapefruit/citrus.

On the other hand, Punched reminds you of the taste of carbonated version of the Hawaiian Punch; however, it is again not that sweet. Moreover, the Punched flavor mostly tastes like Monster Zero Ultras.

Now, both the flavors are fantastic, but the one which I like the most is Silver Ice. Also, if you have tried Monster Zero Ultras and you like the flavor, then I would say that you should try Punched flavor.

Erythritol, Ace-K as well as sucralose are the three artificial sweeteners used to give Pure Zero a more sugary like the taste, and it works well.


A lot go things depends on the time when it comes to the consumption of Rockstar Pure Zero. You need to consume the energy drink in the morning as a coffee alternative or right before any kind of fitness activity.

These energy drinks contain 240 milligrams of caffeine in per servings which, according to a study, is quite plenty to consume in a whole day.

Now if you’re looking for an intense pre-workout, drink one of these before you head to the gym. It’s easy to drink; all you need to do is open like a soda and consume it. You don’t have to premix the drink with anything or any powders that could create a mess.

Ingredients that are good and bad for a Keto Diet

Here is a list of the ingredients that you should take or not while you are on a Keto diet.

1. Carbohydrates

If you’re on a keto diet, then it is being recommended that one must minimize the intaking of carbohydrates. You must intake less than 50g per day as it will help your body to stay in ketosis.

Now, a majority of energy drinks usually contains more than 30g of carbohydrates per serving. So, if you’re going to consume energy drinks, you must be attentive to the intaking sugar capacity.

2. Protein

Well, it is being recommended that one must consume around 50g to 60g of protein per serving. Also, keep in mind that these numbers are rough guidelines and might differ from individual to individual.

Foods like cheese and nuts contain a significant amount of protein. Now, all the energy drinks come with less than 1g of protein per serve, and this is the reason why energy drinks will still have little to no impact on your protein intake while you’re on ketone diet.

3. Sugar

One of the most ignored ingredients, while you’re on a ketogenic diet, is Sugar. One must say a big ‘NO’ to sugar while he or she is following the Keto diet. However, you can still enjoy the sweetness by consuming some artificial sweeteners, which aren’t metabolized by the body.

Drinks like ~ Red Bull Total Zero, Rockstar Pure Zero, and REIZE are some of the examples.

4. Fat

One of the primary sources of energy for an individual who is following a proper Keto diet is fat. It helps you gain energy, and that’s the reason why you can intake fat. But on the other hand, it is recommended that you should only consume the fats i.e., required by your body during Keto diet.

Now, the good news is energy drinks doesn’t contain any fat, and hence there’s no impact on your Keto diet in respect to your energy drink consumption.

Side Effects of Rockstar Pure Zero

Expect the same lift as regular Rockstar except for no sugar rush. However, the Rockstar sticks with the standard energy formulation for Pure Zero.

Rockstar can cause jitteriness, headaches, anxiety, as well as high blood sugar levels. Apart from that, if you mix the energy drink with alcohol, it might mask you the level of alcohol intoxication. Besides, Rockstar has introduced a set of new low-calorie energy drinks that include electrolytes, which are known as Rockstar Recovery, partially in response to these concerns.

Additional Effect ~ If you’re a healthy adult, then you can consume up to 200 milligrams in a single sitting, and 400 milligrams of caffeine in a day. It implies that if you drink a whole can in less than 20 minutes, as you’ll get more caffeine than the recommended in per serving.

If you’re suffering from a fatigue level 4 then this drink can help you recover and gives you suitable amount of energy in emergencies like double-shifts; however, it is recommended that you should not use it regularly.
