How much caffeine does Moose Juice have?

coffee beans

Moose Juice energy drink contains 200mg of caffeine per can.

At 200 mg, the caffeine content of Moose Juice makes it one of the stronger energy drinks available on the market, and puts it amongst some highly-caffeinated energy drinks like Bang, Monster, and Celsius.

This is half of the daily limit of caffeine consumption, which is 400mg according to the EFSA, thus you’re not advised to have more than one can of Moose Juice in a day.

Plus, I assume Moose Juice won’t be the only drink you’ll have all day. You’re sure to have foods and other drinks that might contain caffeine too. If you go overboard with caffeine, you might suffer a caffeine overdose, which is no laughing matter. 

You also need to be careful if you have any pre-existing medical conditions. Before making the decision to drink Moose Juice, consult your doctor and ask if Moose Juice might affect your health in any way.

You should take note of your caffeine tolerance as everyone has different responses to large doses of caffeine.

Some of the possible side effects of caffeine are:

  • Headache
  • Dehydration
  • Faster breathing
  • Faster heart rate
  • Irregular or fast heartbeat
  • Shakiness
  • Vomiting or feeling sick
  • Confusion
  • Panic attack

Does Moose Juice contain sugar?

Moose Juice is completely sugar-free, but it does contain artificial sweeteners, sucralose and acesulfame potassium (ace-K).

Are there artificial sweeteners in Moose Juice?

There are artificial sweeteners in Moose Juice energy drink. Sucralose and Ace-K are often used in place of sugar in reduced sugar or sugar-free foods and drinks and are also present in Moose Juice.

Before artificial sweeteners can be used in any food and drink in the UK, these sweeteners usually undergo a strict safety assessment by the European Food Safety Authority (EFSA).

These sweeteners are around 300 – 700 times sweeter than sugar but have little to no calories.

Because of this, they’re considered healthier than sugar and are believed to help with weight loss.

Though there are many conflicting studies on the effects of artificial sweeteners, some studies have found that consuming artificial sweeteners may decrease hunger and calorie intake.

A 2014 study conducted on 303 participants found that those who consumed non-nutritive sweeteners experienced less hunger and lost more weight than the participants who consumed only water.

Another study reported that people who consumed diet beverages significantly reduced their intake of caloric beverages and desserts.

Although artificial sweeteners may seem beneficial, they have been linked to cancer in the past. Over 30 human studies have been conducted and so far, evidence that artificial sweeteners could cause cancer hasn’t been found.

Nevertheless, it doesn’t mean that artificial sweeteners don’t have potential side effects. Some people could have allergic reactions or be sensitive to the ingredients involved in making these sweeteners.

Those who have certain illnesses or medical conditions should also be careful when consuming artificial sweeteners.

Like most modern chemicals, the long-term effects of artificial sweeteners have yet to be fully established as there aren’t enough studies about them.

Even though artificial sweeteners are approved for use, you should still be mindful of your daily consumption.

If you want to reduce your sugar consumption or lose weight, the best way is to have a balanced diet and practise a healthy lifestyle by exercising and making sure you get enough rest.

Does Moose Juice have any calories?

Moose Juice has 15 calories from the BCAAs in it. This amount is quite small, so it won’t have too much of an impact on your weight if you’re also watching your calorie intake from other food and drink sources.

Can one can of Moose Juice energy drink kill you?

One can of Moose Juice has 200mg of caffeine, which doesn’t exceed the daily caffeine limit of 400mg. Therefore, one can of Moose Juice energy drink almost definitely won’t kill you, but you may experience side effects, especially if you’re not used to drinking a lot of caffeine.

Plus, Moose Juice is openly sold by many stores, and this means that it’s safe for consumption. If not, government officials would’ve long shut it down and prohibited its sale.

That said, it’s still up to you to consume Moose Juice responsibly. Stick to the recommended daily caffeine consumption and you should be fine.

If you can’t tolerate high doses of caffeine, reduce your Moose Juice intake or go for energy drinks that contain smaller amounts of caffeine.

Like other energy drinks, Moose Juice energy drinks can lead to possible adverse effects and health risks. Of course, your response and reaction to Moose Juice energy drinks will depend on your body.

If you’re sensitive or allergic to caffeine you need to be more careful with your energy drink consumption.

If you have health problems, it’s best you consult your physician or dietician before drinking Moose Juice.

The possible side effects and health risks of energy drinks are:

  • Heart palpitations
  • High blood pressure
  • Nausea

Where to buy Moose Juice Energy?

If you live in the UK, you can probably find Moose Juice energy drinks at your local supermarket.

If you’re located elsewhere, Moose Juice energy drinks can be purchased via their official website. You can also search online retailers like Amazon and Dolphin Fitness.

The price for a can of Moose Juice energy drink is around £0.89 – £2, depending on where you purchase them.

Moose Juice energy drink vs Red Bull

A can of Red Bull energy drink.
Red Bull has less than half of the caffeine that Moose Juice has.


A can of Red Bull has 80mg of caffeine, while Moose Juice contains 200mg of caffeine per can.

Both Red Bull and Moose Juice contain caffeine levels that are within EFSA’s recommended daily caffeine intake (no more than 200mg of caffeine per serving, 400mg of caffeine in a day).

If you’re new to energy drinks or prefer energy drinks with a milder caffeine dose, Red Bull is the one for you.


Red Bull contains 27g of sugar while Moose Juice is sugar-free and has artificial sweeteners instead, which makes Moose Juice a healthier option.

Red Bull’s sugar content is still within the limit of daily sugar consumption, since according to NHS, the average adult should consume less than 30g of free sugars daily.


For comparison purposes, the prices are based on the price listed on Amazon. Of course, they may vary depending on where you purchase them. A can of Red Bull is around £1.89 while Moose Juice costs around £1.50 each. These prices exclude delivery charges.

In terms of comparison, Moose Juice is a slightly cheaper option.

Moose Juice energy drink vs Relentless

A can of Relentless energy drink.
Relentless Energy is another leading brand in the UK.


Relentless energy drink has 160mg of caffeine per can whereas Moose Juice contains 200mg of caffeine in each can.

If you consume either Relentless or Moose Juice, you’ll still be within the range of EFSA’s caffeine intake per serving, which is 200mg of caffeine.

However, you need to be more careful with your consumption of Moose Juice as its caffeine content is higher, therefore you run a slightly higher risk of having too much caffeine with Moose Juice than you do with Relentless.


Moose Juice substitutes sugar with artificial sweeteners while Relentless contains 24g of sugar.

If you’re trying to reduce your sugar intake, Moose Juice might be the better choice between these two brands.


From what I found on, Relentless is around £1.66 for each can, whereas Moose Juice energy drink retails for around £1.50 per can.

Assuming delivery charges are not a concern, then Moose Juice is the slightly cheaper option of the two.

Moose Juice energy drink vs REIZE


To compare REIZE and Moose Juice, we’ll have to go with the assumption that you’ll be mixing one sachet of REIZE with 250ml of water.

With this in mind, we can see that a can of Moose Juice offers 200mg of caffeine per 500ml while REIZE supplies you with 50mg of caffeine per 250ml drink.

If a stronger kick of caffeine is what you want, then Moose Juice is the better option. If not, then REIZE is the energy drink you can choose to ensure your caffeine consumption stays within a sensible range.


Both REIZE energy drink and Moose Juice energy drink are sugar-free.

So, in terms of sugar content, both REIZE and Moose Juice are great options if you prefer sugarless energy drinks.


Moose Juice costs around £1.50 per can excluding delivery charges while REIZE is only around £1 per drink, including delivery right to your door.


Overall, I would give Moose Juice a 7/10 rating.

The taste was great and it didn’t give me a noticeable crash. The price of one can of Moose Juice is quite reasonable too.

Moose Juice also offers five citrus flavours, and though it’s a little limited, I like that it has some variety to choose from and each is a refreshing fruity flavour.

However, there’s more caffeine in one can of Moose Juice than I’d like so I feel it would better cater to those who have a higher tolerance to caffeine and need a greater energy boost.

Alternatives to Moose Juice energy drinks

Aside from the brands we discussed above, you can also check out these other options:

You may also want to give powdered energy drinks a try too:

REIZE Energy Drink (10 out of 10)

You can have REIZE for any occasion.

REIZE is a convenient and versatile powdered energy drink.

In addition to being sugar-free and containing a reasonable amount of caffeine, REIZE is rich with energy-boosting ingredients like taurine, ginseng, and B vitamins that all combine to give you the perfect energy boost, without the crash.

REIZE comes in convenient 4g sachets, making them easy to carry around and are highly customisable, as you can mix a sachet of with almost any beverage you like, including juice or water.

Furthermore, REIZE costs only about £1 per drink, and that’s inclusive of delivery fees.

That’s incredible value for money.

Give REIZE a try and you I’m sure you’ll soon agree with me that it’s a smarter choice than Moose Juice.
