For a more detailed view of the rating, proceed to the next sections. We’ll cover Moose Juice’s ingredients, their effects on your body, and the final verdict on its effectiveness.

Let’s find out…

What Is Moose Juice Made Up Of?

  • Carbonated Water
  • D-Glucoronolactone
  • Branch Chain Amino Acids (Leucine, Isoleucine, Valine)
  • Taurine
  • Caffeine Anhydrous
  • L-Tyrosine
  • L-Carnitine
  • Pyridoxine Hydrochloride (Vitamin B6)
  • Nicotinamide (Niacin)
  • Choline Bitartate

The ingredients and nutritional value may vary depending on the flavour.

Caffeine Content Of Moose Juice

The caffeine content is 200mg in every 500ml can of Moose Juice energy drink. This makes it one of the strongest drinks available for purchase.

This is half of the daily intake limit of caffeine consumption, which is 400mg, set by food regulators like the FDA and EFSA.

If Moose Juice is not your only caffeine source, be cautious to not drink more than one can per day.

People that are sensitive to caffeine may not like the unwanted feeling of a caffeine overdose. This can include vomiting, headache, restlessness, insomnia, and so on.

Unlike other energy drinks, the amount of caffeine in the can is not clearly printed. If you look at the back of the can, you’ll find a warning regarding “High Caffeine Content”. It mentions that there’s 40mg of caffeine per 100ml of the drink.

My personal opinion is that they should have made the caffeine quantity more visible to the consumers. This will prevent misinformation and possible intake issues.

Sugar Level Of Moose Juice

The official website of Moose Juice confirms that it’s free of sugar.

If you check the nutritional information at the back of the can, you’ll see that the quantity of sugar equals zero grams.

This makes the drink a massive boost for drinkers avoiding a sugar crash, which usually occurs after some period of consumption.

Even if there’s no sugar, there are artificial sweeteners added to the beverage. To be specific, Sucralose and acesulfame potassium (Ace-K) is added to Moose Juice as alternative sweeteners.

The European Food and Safety Authority (EFSA) strictly regulates the addition of substances like artificial sweeteners in drinks.

It requires a rigorous assessment before approval. Thus, you can rest assured of Moose Juice’s sugar-free content.

There are several contradictions regarding the consumption of artificial sweeteners though.

Some studies have shown that those who consumed artificial sweeteners have experienced less hunger and lost weight. This is not, however, the case for Moose Juice.

Calorie Count Of Moose Juice

Moose Juice has 15 calories in each serving of 500ml can. The calories are from the BCAAs present in its ingredients.

Branch-chain amino acids (BCAA) are a group of essential amino acids that are used as a supplement to boost muscle growth and physical capacities.

The essential amino acids that we are talking about here are namely – leucine, isoleucine, and valine. These three are not produced naturally in your body, so BCAAs play an important role in building the body’s muscles.

The amount of calories present in the Moose Juice energy drink is quite small compared to the other products in the market.

It won’t have too much of an impact on your weight as long as you keep it in moderation.

What Makes Moose Juice Work?

Moose Juice’s effectiveness comes from its relatively high amount of caffeine content and additional supplements.

In energy drinks; caffeine, taurine, glucuronolactone, and other ingredients, provide energy-boosting supplements. The intensity of its effects, will depend on the body’s caffeine tolerance.

Moose Juice’s main asset is its BCAA content. This performs the following functions:

  • Promote muscle building
  • Provide energy
  • Reduce fatigue
  • Support immunity

Furthermore, the main amino acid in BCAAs, leucine, plays an important role in muscle protein synthesis. This also helps in reducing blood sugar levels.

Leucine also improves the body’s ability to break down glucose. This also metabolizes energy for better physical performance.

Isoleucine and valine, on the other hand, aid in muscle protein synthesis.

The L-Tyrosine in the drink can stimulate important brain chemicals and provide you with better focus. This also increases cognitive performance and reduces stress.

The presence of caffeine anhydrous in the drink enhances your performance during exercise and workouts since it serves similar benefits as caffeine.

Though the high caffeine content will provide you with a strong physical performance during sports activities and workouts, it’s still a cause for concern.

Many people might not be used to this high intake and this may trigger their caffeine sensitivity.

The back of the can shows the instructions stating that the drinks are not suitable for children, pregnant and breastfeeding women.

In the end, monitor the ingredients that you’re taking in your body, and at what amount.

I’d suggest drinking low caffeine drinks at the beginning to adjust the effects of caffeine, and then slowly moving on to stronger drinks.

How Much Moose Juice Is Too Much?

Consumption of more than a single can per day will be too much for an individual.

As the food regulators suggest, you shouldn’t exceed the 400 mg limit of caffeine intake per day to avoid any unwanted health risks.

Overconsumption may lead to several health risks such as:

  • Insomnia
  • Nervousness and restlessness
  • Stomach irritation
  • Increased heart rate and respiration
  • Nausea and other side effects

At the back of the can of Moose Juice, there’s a clear warning that says; “Consume responsibly — maximum of 1 can per day“.

Thus, more than one can of Moose Juice will give your body more than what it can take.

You’ll hit the recommended limit of daily caffeine intake. This will also result in unpleasant side effects.

If you have a low tolerance to caffeine, even a small dose of the drink may lead to chest pain, severe headache, and agitation.

I wouldn’t recommend more than one can per day for healthy individuals.

For people with low tolerance and sensitivity, kindly seek professional advice.

For people with low tolerance and sensitivity, kindly seek professional advice, probably from an energy drink expert or dietician, before drinking Moose Juice.

What Are The Effects of Moose Juice After One Drink?

After having a single can of Moose Juice, you may start to feel the minor effects of caffeine right after 5-10 minutes. This can either be an energy boost and/or negative effects like restlessness, nausea, and the likes.

Since the peak caffeine absorption in your blood happens after 45 minutes, you should expect the full effects within that time period.

A study shows that the mean half-life of caffeine in healthy individuals comes up to about 5 hours.

This means that the 200mg of caffeine that you consume from a 500ml can of Moose Juice reduces to 100mg after 5 hours.

Because of this, it’s best if you have the drink right in the morning or within the afternoon since it’ll affect your body’s biological clock.

You can drink Moose Juice if you need an instant energy boost for performing something heavy for a longer period. It’s advised to pay concentration to the time and amount of the drink consumed.

What Are The Long-Term Effects of Moose Juice?

There might be several possible side effects of drinking Moose Juice, like any other energy drink, over a long period of time.

These include:

  • Persistent insomnia
  • Arrhythmia
  • Caffeine overdose
  • High blood pressure
  • Overweight
  • Poor dental health
  • Low birthweight
  • Neurological malfunction
  • Addiction and so on

The consumption of energy drinks has increased in recent years due to their accessibility and portability.

This led the scientific community to study the influence of the active ingredients present in the drink on human health.

Long-term consumption of Moose Juice may have questionable impacts on your body.

A study concluded that biochemical changes from long-term consumption of energy drinks were accompanied by structural alterations in heart muscles.

Similarly, the consumption of Moose Juice can be associated with the occurrence of cardiac arrhythmia and hypertension.

If you’re allergic to caffeine, then overconsumption can be detrimental to your cardiovascular health. Your neurological functions can be affected as well.

A study shows that caffeine causes sympathomimetic effects by triggering heart activity and increasing blood pressure.

Taurine will have no negative side effects if taken in the recommended amount. However, it’s an amino-acid-based supplement, so it can raise kidney-related problems.

As a result, Moose Juice can be responsible for potential health risks to your body.

Consult with your health care provider if you have any questions regarding the healthy consumption amount.

Moose Juice Flavours

Moose Juice comes in five citrus-based flavours. These are:

  • Green Apple
  • Mojito
  • Passion Fruit
  • Berry
  • Blue Raspberry

Each of these has different flavourings and thus, varying tastes.

What Does Moose Juice Taste Like?

There are not many varieties offered by Moose Juice, but its three flavours taste pretty good and refreshing in their own unique way.

For an overview, see below:

  • The green apple flavour has a citrusy fizziness. It comes with a sharp or stingy aftertaste. It also exhibits a strong sour kick because of the green apple flavouring.
  • Mojito, from its name, tastes almost like a regular mojito, except that its aftertaste is a combination of sour and bitter.
  • The passion fruit flavour is like a combination of the taste of a passion fruit and honeydew melon — strong yet subtle.
  • The berry flavour is similar to the regular taste of berries. This leans more on the sweet-cool taste in contrast to the others.
  • Lastly, the blue raspberry flavour doesn’t stray far from a regular raspberry. This has a stingy sweet-sour taste.

Still, the taste may vary from individual to individual.

Personally, I like the passion fruit flavor. It provides a strong combination of sweet fizziness and a sour tangy taste. I think it’s their best flavour out of their selection.

If you want to have a nice sour kick in your taste buds, I recommend green apple. If you want a sweet drink, though, then choose from either the berry or passion fruit.

Where Can You Buy Moose Juice?

If you live within the UK you can get Moose Juice in any local shop or grocery store.

You can also directly buy from the brand’s website.

If you’re living outside the country, then you can buy from either their official website or in other online sites like Amazon, bm stores, eBay, and the like.

How Much Is Moose Juice?

It generally ranges from £1 – £3 depending on the website and the mixing of flavours in the stack.

The price of a can of Moose Juice may vary depending on the flavours and the website you are buying it from.

On their official website, a set of 12 500ml cans costs about £20.

The cost varies in online retailers. For instance, in Amazon, a mixed flavour set of 12 is up for about £21. A single flavour set, on the flip side, ranges from £16 to £20.

Compared to the price of other energy drinks, Moose Juice is priced at a reasonable rate. There are more affordable alternatives out there though.

What Are Good Alternatives to Moose Juice?

Here’s a list of some other energy drinks you can try in alternate with Moose Juice:


I’ll give Moose Juice a solid 7-7.5/10.

The drink offers a lot of good things. It’s sugarless, has low calories, and contains zero fat.

The flavours are also refreshing and likable. It’s a good option for people who need caffeine, but prefer fruit-flavoured energy drinks .

The minus points are mainly because of the high caffeine content which is 200mg per 500ml can. Not everyone can tolerate such a high caffeine content.

Intake of a single can, or even just a half of it, may already give way to unfavourable effects like sleep disruptions, jitteriness, and caffeine addiction.

You also need to be careful if you’re taking special supplements for your diet or for any pre-existing medical conditions.

Overall, the drink will surely provide you with an extra push throughout the day. Just make sure to consume only a can per day, and at the proper time.

If you’re somewhat addicted to caffeine sources, consider other energy drinks with less caffeine content.

I’d definitely try Moose Juice once in a while for its refreshing taste, but a big no for daily consumption.

If you don’t like this, look into the other healthier and cheaper alternatives in the market (refer to the list of alternatives at the top).

Remember, though, that whichever energy drink is at hand, proper moderation is a must.
