Xyience Energy Drink Caffeine and Ingredients (all info)

What is Xyience energy drink? 

Xyience energy drink (pronounced ‘Science’ with a Z instead of an S) is a carbonated energy drink that claims it is a ‘naturally flavored energy drink’ with zero calories and sugar. 

Xyience is clearly trying to target the health conscious energy drinkers, as the Xyience can also boldly states that it is ‘vitamin fortified’- which is not entirely incorrect. It does contain vitamins B12 and B6, which are water soluble vitamins that are passed safely out through urine if taken in excess. 

The only thing I’m not quite sure of is the ‘natural flavors’, as I can’t quite seem to work out where or what these flavors are being derived from. 

Besides energy drinks, Xyience has a line of drinks for bodybuilders, which are meant to help you with your workout and can be found in gyms all over the US.

Xyience energy drink ingredients 

A single 16 fl.oz can of Xyience energy drink contains: 

  • 0 calories 
  • 0g total fat 
  • 176mg caffeine / 16 fl.oz 
  • 160mg sodium 
  • 15mg potassium 
  • 2g carbohydrates 
  • 0g sugars 
  • 0g protein 
  • Niacin (100% of the daily recommended value) 
  • Vitamin B6 (250% of the daily recommended value) 
  • Vitamin B12 (80% of the daily recommended value) 
  • Pantothenic acid (500% of the daily recommended value) 

It is not a significant source of calories from fat, saturated fat, trans fat, cholesterol, dietary fiber, vitamin A, vitamin C, calcium and iron. 

Xyience also contains trace amounts of: 

  • Carbonated water
  • Citric acid
  • Taurine
  • Natural flavors 
  • Sodium Citrate
  • Caffeine 
  • Glucuronolactone
  • Potassium sorbate (preservative
  • Sodium benzoate (preservative
  • Calcium D Pantothenate (Vitamin B5) 
  • Ginseng root extract 
  • Guarana seed extract
  • Sucralose
  • L-Carnitine
  • Gum Arabic 
  • Niacinamide (Vitamin B3) 
  • Inositol
  • Acesulfame potassium
  • Ester gum 
  • Pyridoxine hydrochloride (Vitamin B6) 
  • Cyanobalamin (Vitamin B12) 

One thing that really jumps out at me is the sneaky way they’ve marketed both the caffeine and the sugar content.

Despite the fact that they’ve emblazoned 0g sugar on the rim of the can, that’s only natural, complex sugars and syrups. They absolutely do have a sweetener, sucralose inside the drink. While they might not technically be wrong, I think it’s not entirely accurate to then market the drink as having ‘0g sugar’. 

In addition to that, they also mention on the back of the can that 8 fl.oz of Xyience energy drink contains 88mg of caffeine. I’m not sure about you, but my mental maths isn’t good enough to multiply 88mg of caffeine by 2 on the spot without whipping out my phone calculator.

In addition to that, there’s so much room for error on the part of the customers! If you’re casually browsing, you would more or less expect for them to be upfront about the total caffeine content within the 16 fl.oz can, not ask you to suddenly do math just to figure it out. 

In case you were wondering, 88 times 2 equals 176- the amount of caffeine in a can of Xyience– they just tell you that there are 2 servings per can and then give you the “per serve” figure. 

Clear as mud.

Xyience energy drink caffeine content 

In total, Xyience energy drink contains a total of 176g of caffeine in a single 16 fl.oz drink.

If we keep in mind the fact that the maximum daily recommended limit for caffeine consumption in an adult is 400mg, a single can of Xyience brings you up to about half of this daily limit. 

With 176mg of caffeine per can, Xyience is among the stronger energy drinks on the market. 

The warning on the back of the can also reminds you that it is not recommended for children under 18, women who are pregnant or breastfeeding, and people who are particularly sensitive to caffeine. 

They also don’t recommend that you drink this product while simultaneously consuming alcohol, or mixing both together. 

Some possible side-effects of a caffeine overdose are: 

  • Anxiety/panic attacks
  • Dehydration 
  • Diarrhea 
  • Headaches 

What is Guarana seed extract? 

Guarana seed extract is derived from the guarana plant, which is named for the Guarani tribe in the Amazon. 

Guarana contains caffeine, which in turn, stimulates the central nervous system and gives you the energy boost that you need. Besides caffeine, guarana also contains the chemicals theophylline and theobromine, which have a similar effect on the body as caffeine does. 

Guarana has no known side effects besides those that usually come with an overconsumption of caffeine- side effects that come with that can be seen above. 

How much guarana seed extract is in Xyience?

On the surface, it seems that there is 176mg of guarana seed extract in Xyience, but because they haven’t stated exactly how much of this caffeine is from the seed extract, it’s possible that this natural extract is supplemented by synthesized caffeine, which has the same chemical makeup as natural caffeine, so there’s nothing much to worry about.

What is Sucralose? 

Sucralose is an artificial sweetener that is supposed to replace natural sugars in food and drink. Although sucralose has been deemed safe by government authorities, there have been concerns about the side effects that occur after consuming this sweetener. 

Sucralose is a simple sugar made from sugar in a chemical process where 3 hydrogen-oxygen groups are replaced with chlorine atoms. 

Sucralose has been found to reduce good gut bacteria (the ones that help improve your digestion- this study found that up to 12 weeks after the experiment, the gut bacteria had still not returned). It can also help you lose weight to some extent, if you replace sugar in your diet with sucralose- but not enough evidence about the effects of long-term use of sucralose have been examined. 

As with many modern chemicals, there often isn’t enough precedence for scientists and researchers to clearly state that these are side effects that are associated with the chemicals- only data collected over time will tell what effects the chemicals really have on the human body. 

Xyience energy drinks against white background
Xyience may not be entirely truthful with the way it’s marketing its drinks.

Xyience vs Red Bull


Xyience has 176mg caffeine / 16 fl.oz, while Red Bull only has 80mg of caffeine / 8.4 fl.oz.

Xyience has double the amount of caffeine that Red Bull does, and it seems that Red Bull uses a combination of caffeine, sugar and taurine in order to give their users an energy boost, but Xyience leans very heavily on caffeine. 

If you are caffeine sensitive, it’s probably better for you to try another energy drink with a lower caffeine content, like Red Bull or REIZE, which both contain under 100mg of caffeine. 


Xyience contains 0g of sugar, but Red Bull contains 26g of sugar / 8.4 fl.oz

Red Bull gets its sugar from the simple sugars sucrose and glucose, which have been broken down from complex sugars. In contrast, Xyience uses sucralose, the artificial sweetener, and it is unclear exactly how much artificial sweeteners are included in the drink. 


A pack of 8 Xyience energy drinks that are each 16 fl.oz usually cost around $33.95, which means that a single can of Xyience costs around $4.25.

In contrast, Red Bull only costs around $1.99 per can.

Xyience is about double the price of Red Bull, and it certainly does not have the same international acclaim or impact. If you’re caffeine sensitive or aware that you don’t want to consume artificial sweetener, then you may prefer Red Bull over Xyience.

Xyience vs Monster 


Xyience has 176mg caffeine / 16 fl.oz, and Monster is similar, with 179mg of caffeine / 16 fl.oz. 

Xyience seems to get most of its energy from caffeine, as does Monster. As mentioned before, these drinks contain about half of the daily recommended limit of caffeine for an adult, which does come with its own problems. 

If consuming either of them, make sure that you’re keeping track of any other caffeinated products that you are consuming on the side, including sodas. 


Xyience contains 0g of sugar, compared to Monster’s whopping 52g of sugar / 16 fl.oz

While Xyience contains 0g of natural sugar, it does contain artificial sugars, sucralose. In contrast, while Monster may contain 52g of sugar, it gets them from simple sugars such as glucose, which comes from natural sugars that have been broken down. 

Artificial vs natural- it’s up to you which you think is better. 


A pack of 8 Xyience energy drinks that are each 16 fl.oz usually cost around $33.95, which means that a single can of Xyience costs around $4.25. 

It’s $37.95 for a 12 can pack of Monster Import energy drink on Amazon, which means that it’s around $3.20 for a can, excluding shipping. 

Check the current Amazon prices here. 

Despite the fact that both are pretty much the same besides their sugar content, Xyience is a whole dollar more expensive than Monster. 

Personally, I can’t really see the reason for this because in my opinion, Xyience doesn’t really have anything that makes it stand out from the competition.

If I wanted an energy boost at an affordable price, I’d stick with Monster, Red Bull, or REIZE, which is an affordable and effective powdered energy drink. 

Xyience isn’t particularly good for you, but neither is it entirely bad- it’s a perfectly standard energy drink.

Xyience vs Bang 


Xyience has 176mg caffeine / 16 fl.oz, and Bang has nearly double that at 300mg of caffeine / 16 fl.oz. 

Bang has a lot more caffeine than Xyience, but I think both are marketed really similarly. Both target customers that are looking for an energy boost from ‘natural sources’, although neither really achieve that. 

Bang seems a lot more potent than Xyience on these terms, and both are the same size- 16 fl.oz. 


Xyience contains 0g of sugar, and Bang energy drink has 0g sugar as well. 

However, both energy drinks still use artificial sweeteners- they share one sweetener, sucralose, whose side effects have been explained above, and Bang also uses acesulfame potassium. 

This also means that both Bang and Xyience are both more or less guilty of some amount of false advertising in my opinion- it’s not completely true that there are no sugars in either. 


A pack of 8 Xyience energy drinks that are each 16 fl.oz usually cost around $33.95, which means that a single can of Xyience costs around $4.25.

Bang costs around half of that at $2.17 per can. 

Similarly with Monster, Xyience is really similar to Bang in the way that it’s marketing itself, and for the price that it’s charging, around $4 per can, I’m not sure why someone who choose to drink Xyience over another drink like Bang.

Xyience vs REIZE 


Xyience has 176mg caffeine / 16 fl.oz, while REIZE only has 50mg of caffeine. 

REIZE may seem like it does not have a lot of caffeine, but it makes up for it by including 1000mg of taurine, a substance that has been proven to provide good, clean energy. 

In contrast, Xyience seems to tack all its energy boost onto caffeine, which while might be effective for some people, doesn’t work for everyone. 


Xyience contains 0g of sugar, and likewise, REIZE is completely sugar free. 

REIZE does contain artificial sweeteners, but these have been extensively tested- acesulfame potassium and aspartame, the same ingredients used to sweeten Coke Zero Sugar and many other common products. 

In contrast, Xyience only uses sucralose, which does come with potential side effects, and not much research has been conducted on it. 


A pack of 8 Xyience energy drinks that are each 16 fl.oz usually cost around $33.95, which means that a single can of Xyience costs around $4.25. 

REIZE is a lot cheaper, at only around $1 per sachet, which can make a 8 fl.oz drink. 

If you’re looking for efficiency that comes at a good price, then REIZE is the drink for you, as opposed to the massively overpriced Xyience.

In addition to that, REIZE is fully customizable- just add the water, juice or sparkling water of your choice in order to enjoy a lovely and energizing beverage.

Alternatives to Xyience energy drink 

There are lots of great energy drinks on the market. If you’re looking for some similar, liquid based energy drinks that give a bit more energy than Xyience, take a look at: 

• Monster 

• Red Bull 

• Rockstar 



 Monster Import (different to original Monster)

 Rip It

 Bing energy drink 

 Bang (not to be confused with Bing!)


Powdered energy drinks are also an option, and they tend to be more convenient and also more affordable than a lot of the market leading energy drinks, but with the same great flavor and efficacy:  

You could also take a look at other products like Vivarin caffeine pills if you are looking for something that’s quick and easy to take. The energy boost may not be up to scratch with some of the above mentioned energy drinks though.

Make it Mio by Kraft is also worth a look. 

Personally, my all-time favorite energy boosting buddy is REIZE Energy Drink. REIZE is a powder energy drink that comes in convenient little sachets that you can mix fresh when you need a boost. 

Instant energy, just add water!

With 50mg of caffeine, REIZE doesn’t have the same amount of caffeine that Xyience does, but it is a lot more convenient, affordable and flexible, since you can add all types of liquids to it – soda, hot water, cold water, flavored juice, it’s up to you!

REIZE ships right to your door for around $1 per drink, much cheaper than Xyience and most energy drinks on the market. 

Give it a try today and you might just find that you prefer it to Xyience.
