Moose Juice Energy Drink review (does it work?)

Moose Juice Energy Drink review (does it work?)

Made in the United Kingdom, Moose Juice Extreme Energy is a product of Muscle Moose and is distributed by Harper Innovations.

This brand of energy drink is marketed at athletes, fitness, and health enthusiasts. Muscle Moose even has its own line of energy shots and protein snacks.

Moose Juice is stated to have a low-calorie count, zero sugar and zero fat. They’re perfect for a quick caffeine fix during a busy day at work or a pre-workout before hitting the gym, but is it deserving of the hype?

If you just want the quick answer, I think Moose Juice scores a 7 out of 10, but there are reasons for not scoring higher and there are also better options.

Read on for my honest take on Moose Juice Extreme Energy as we dive into all the details.

Let’s get started…

What are BCAAs?

Branch-chain amino acids (BCAA) are a group consisting of three components: leucine, isoleucine and valine.

If you don’t care too much about the details of what BCAA’s are, you might want to just skip this section.

Since these essential amino acids can’t be made naturally in your body, you have to take them as supplements because BCAAs play an important role in building up your body’s proteins and muscles.

Studies have proven that BCAA supplementation prevented muscle breakdown during exercise and increased muscle protein synthesis (muscle growth) in the body.

BCAA supplementations might have the potential to reduce muscle damage and promote faster recovery after physical exercises.

BCAAs can also decrease fatigue and improve both physical and cognitive performance.


Leucine is considered to be the ‘main amino acid’ in BCAAs. Compared to isoleucine and valine, leucine has the most impact on muscle protein synthesis as it can trigger the process by activating a protein called mTor.

Besides, it also seems to have certain properties that could help in reducing blood sugar levels, though its effects aren’t as potent as isoleucine and valine.


Leucine is better known for its ability to regulate blood sugar levels in the body. It improves the body’s ability to break down glucose and metabolise it as energy for exercise.

Though there aren’t many studies about how effective isoleucine is, it may have potential as medication to lower blood sugar levels for diabetics or a pre-workout that could enhance performance.


Like leucine and isoleucine, valine can aid in muscle protein synthesis and blood sugar regulation.

What is L-Tyrosine?

L-Tyrosine is a naturally occurring amino acid in the body. It’s commonly taken as a dietary supplement to increase attention, concentration and alertness. According to several studies, L-Tyrosine might be beneficial in reducing stress therefore promoting enhancements in cognitive function.

It can be found in many high-protein foods like cheese, chicken, turkey and fish.

As beneficial as it is, L-Tyrosine can cause side effects and should be taken with care if you’re on medication or are planning to.

Is Moose Juice Energy Drink REALLY good for you?

In my opinion, I wouldn’t say Moose Juice energy drink is bad for your health. But it isn’t exactly the healthiest option either.

Moose Juice has zero sugar and fat and has a low-calorie content. They’re perfect if you want to reduce your sugar and calorie intake.

Instead of regular sugar, Moose Juice substitutes them with artificial sweeteners, namely sucralose and acesulfame potassium.

However, Moose Juice has a hefty of 200mg of caffeine, which may not be good for you in the long term. That much caffeine could lead to undesirable side effects.

Though Moose Juice does contain nutrients like taurine, B vitamins and other essential amino acids, their specific quantities aren’t mentioned on the nutrition label.

Thus it’s hard to know if these nutrients will have a positive effect on your body.

From my perspective, the high caffeine content and the general marketing of Moose Juice make it more suited as a pre-workout drink or an energy booster for athletic performance rather than an everyday energy drink.

Moose Juice Energy Drink Review: Caffeine     

Moose Juice Extreme Energy drink contains a high caffeine content, with 200mg in each can.

With that amount of caffeine, Moose Juice is one of the stronger energy drinks available in the market. In my opinion, this would have quite an overwhelming effect if you have low caffeine tolerance.

Caffeine needs to be consumed in moderation.

From the guidelines provided by the European Food Safety Authority (EFSA), it should be safe to consume up to 200mg of caffeine per serving. For healthy adults, it’s recommended to limit your caffeine intake to less than 400mg in a day.

My personal caffeine preference is around 50mg – 100mg of caffeine per drink. Any more than that is a risk I’m not willing to take.

For intense workouts at the gym or during a busy day at work, I’d recommend Moose Juice as a great energy booster.

But as a light pick-me-up or a casual beverage, not so much. Besides, there’s even a warning on the can that says to consume only one can in a day.

If you’re not careful, you could easily exceed your caffeine intake, which could lead to some nasty side effects. I definitely believe you can find other equally-delicious energy drinks out there with safer doses of caffeine.

Studies have shown that caffeine works as effectively in low-to-moderate doses in enhancing physical and mental performance as higher dosages of caffeine do.

In fact, I’d say Moose Juice should be consumed as an occasional drink rather than a daily one for the benefit of your health.

Moose Juice Energy Drink Review: Taste

Moose Juice actually tastes pretty good. I particularly liked the Green Apple flavour. The Moose Juice green apple flavour has a citrus-y fizziness to it that tasted like sherbet and was really delicious.

You may find that Moose Juice is a little limited when it comes to flavours, but each one is bound to refresh your taste buds.

With artificial sweeteners as sugar replacements, you’ll still get to satisfy your sweet tooth without the extra calories.

Is Moose Juice your kind of energy drink?

Moose Juice Energy Drink Review: Effects

Does Moose Juice really work?

I’d say Moose Juice did work for me, but honestly, there was more caffeine than I prefer in a single serving.

Though this is just from my own point of view and it might turn out differently for you if you have a lower or higher caffeine tolerance.

Another thing to note is that Moose Juice contains caffeine anhydrous, a concentrated powdered form of caffeine.

It is probably used to substitute regular caffeine since it’s known to increase exercise performance and comes in standard dose measurements.

One study comparing the efficacy of caffeine and caffeine anhydrous found that both substances had similar positive effects on physical performance. Both caffeine and caffeine anhydrous were considered suitable as pre-exercise supplements for intense exercises.

Considering the high caffeine content in Moose Juice, I feel the potential of this energy drink will shine better during physical exercises as you use its powerful energy boost to help you get through intense workouts or sports activities.

What are the side effects of drinking Moose Juice?

The high quantities of caffeine in Moose Juice Energy is a cause for concern if you’re not used to having this much caffeine per serving.

The side effects might differ according to your caffeine tolerance. You must also take caffeine sensitivity into consideration.

I’d suggest limiting your consumption of Moose Juice to one to two cans in a week or starting with energy drinks with lower caffeine content before moving up to stronger energy drinks like this one.

On the back of the can, it’s stated that Moose Juice is not recommended for children, pregnant or breast-feeding women.

In the end, you’re the one who understands your body best and you’re responsible for monitoring your own wellbeing.

Moose Juice Energy Drink Review: Price

The price of a can of Moose Juice ranges from £0.89 – £2.00 depending on which flavours you want and the place you get them.

Take into consideration that these prices exclude delivery costs if you’re purchasing Moose Juice online.

Moose Juice stands at reasonable priced, though in my opinion, there are more affordable energy drinks out there.

Here’s a quick comparison between Moose Juice and some of the big-name brands (namely Rockstar, Monster and Red Bull) in terms of caffeine, sugar and calories.

Moose Juice Review: Final Verdict

Personally, I would give Moose Juice a solid 7/10.

The zero sugar, zero fat and low calories definitely earned Moose Juice some brownie points. The flavours are pretty refreshing, they’re a good option if you have fruit flavoured preferences.

My main concern is the 200mg of caffeine in each can of Moose Juice energy drink. High doses of caffeine like this can cause unfavourable side effects such as caffeine addiction, sleep disorder, high blood pressure, anxiety and can even be lethal.

Alternatives to Moose Juice Extreme Energy Drink

There are plenty of good alternative energy drinks to Moose Juice. Here’s a list of some of them:

Powdered energy drinks also make great options and are usually more affordable than ready-to-drink cans:

REIZE Energy Drink (10 out of 10)

REIZE Energy Drink is very convenient.
REIZE is perfect for any occasion

When it comes to energy drinks, REIZE is my number one pick.

Unlike Moose Juice’s whopping 200mg of caffeine, REIZE contains a sensible 50mg of caffeine per serve. This amount pretty much guarantees little to no side effects while still giving you a nice energy boost.

REIZE is also sugar-free, which means you won’t have to worry about sugar crashes later on.

REIZE only has 11 calories per 4g sachet and would be perfect if you’re watching your calorie intake. Plus, REIZE is loaded with healthy ingredients like taurine, B vitamin and ginseng that work in harmony with the caffeine to provide the perfect energy boost.

Perhaps best of all, you can get REIZE delivered right to your door for only around $1 per drink, and that includes delivery charges too.

That’s incredibly good value.

Give REIZE a try and I’m sure you’ll also find that REIZE is a better choice than Moose Juice.
