How Much Caffeine is in Moose Juice?

A single 500ml can of Moose Juice has 200mg of caffeine.

A 200mg of caffeine in an energy drink is pretty strong caffeine content. However, it depends on a person’s caffeine tolerance.

A 200mg of caffeine can be a lot of caffeine if you have a low caffeine tolerance. But if you’re more tolerant towards caffeine, 200mg won’t be a big deal for you.

No matter how tolerant you are towards caffeine, the European Food Security Authority (EFSA) limits our daily caffeine intake to 400mg of caffeine per day.

Consumption of caffeine over 400mg can lead to certain side effects like:

  • Insomnia
  • Increase in heart rate
  • Restlessness
  • Jitters, etc.

Personally, my caffeine tolerance is 50-100mg of caffeine in one serving of energy drink. Anything more than that can leave me feeling hot flushes.

Here is a detailed video on caffeine.

How Many Calories Does Moose Juice Have?

Moose Juice has 15 calories each serving.

2,000-2,500 calories are recommended daily for adult males and females. The calorie content varies from different person to person, depending on their age, body metabolism, physical activity, gender, etc.

A 15 calories for an energy drink is very few calories. Even if you’re on a low-calorie diet, 15 calories will hardly put a dent.

How Much Sugar Does Moose Juice Have?

Added sugar is not the best option for our health. Doctors advise patients to consume added sugar as little as possible. Considering overconsumption of sugar leads to noticeable health problems like:

  • Inflammation
  • High Blood Pressure
  • Weight Gain
  • Diabetes

The NHS recommends 30g and 24g sugar a day, for men and women.

We don’t have to worry about all the side effects of added sugar since Moose Juice uses artificial sweeteners to sweeten its drink.

Which Artificial Sweeteners Are Used In Moose Juice?

Moose Juice markets its energy drink to be aspartame-free. The sweeteners used in Moose Juice are Sucralose and Acesulfame-K.

Sucralose is a zero-calorie sweetener used by many energy drink brands to provide the “diet-friendly” option.

Sucralose is not stored in our body and is 600 times sweeter than sugar. The most common product of Sucralose is Splenda, which is used by many diabetic patients.

Acesulfame-K is another zero-calorie sweetener used in many sodas, energy drinks, sugar-free gums, etc. Acesulfame-K is 200 times sweeter than regular sugar and isn’t metabolized by our body.

Both of these sweeteners are approved for food uses in the UK.

Artificial sweeteners don’t have any major side effects unless you go overboard with your consumption.

Check this video by Healthline out on whether Splenda is healthy or not.

Does Moose Juice Have BCAAs?

Moose Juice has 3 BCAAs. Namely, Leucine, Isoleucine, and Valine.

If you’re wondering what BCAAs are, BCAA means Branched Chained Amino Acids.

BCAAs help with the growth of muscles, increasing overall muscle mass and decreasing muscle soreness. Many bodybuilders and fitness enthusiasts take BCAA supplements.

Aside from supplements, BCAAs are found in protein-rich foods like fish, meat, dairy, etc.

Multiple studies show BCAAs increasing both mental and physical performance.

Which B-Vitamins Are Used In Moose Juice?

Moose Juice primarily has 4 B-vitamins. They are, vitamin B3, B6, B9, and B12.

These vitamins are also known as niacin, pyridoxine hydrochloride, folic acid (also known as folate), and cobalamin in the drink.

Now, let’s take a look at the benefits of B-vitamins.

What Are The Benefits of B-Vitamins?

Few health benefits of B vitamins are:

  • Good cell health
  • Promoting growth of red blood cell
  • Clear eyesight
  • Good brain function
  • Better food appetite
  • Healthy function of nerves
  • Healthy digestion, and so on.

All of the benefits mentioned above are promoted or improved by B vitamins.

But the bad news is, although Moose Juice used these vitamins, the vitamin content is way higher than their tolerable intake. Overconsumption of B vitamins can sometimes lead to a vitamin overdose.

Check out this video on vitamin overdose and the side effects of overconsumption of vitamins.

Another important thing to mention is that B vitamins are water-soluble. This means the extra vitamin content is pretty much useless as it will be flushed down by our body at the end of the day.

What Are The Benefits of Moose Juice?

Moose Juice is a sports energy drink and this naturally means, the drink offers a lot of benefits. Some of which includes:

  • Makes you feel refreshed
  • Improves your energy level
  • Better physical and mental performance
  • Improved focus and concentration

These outcomes can help improve some aspects drastically, keep in mind, the benefits work the most if consumed in moderation.

Can Moose Juice Make You Lose Weight?

Moose Juice alone can not help you lose weight.

Moose has 200mg of caffeine with no added sugar. After drinking the energy drink, you may feel energized and all. But it goes away after a few hours.

But this does not mean it will make you lose weight, it’s not a weight loss supplement.

The good news is, if you drink Moose Juice along with following a healthy diet and working out regularly, the energy drink might help you lose weight.

A good energy drink or a pre-workout before a long workout session works like a charm.

Is Moose Juice Vegan-Friendly?

Moose Juice probably is not vegan-friendly considering it uses a few ingredients that may come from animal sources.


L-tyrosine is an amino acid whose origin is protein-based foods. Meaning, meat, fish, eggs, etc.

However, L-tyrosine is found in many supplements and is designed to enhance our cognitive performance, alertness, focus, etc.

Amino acids usually come from direct plants or are synthesized. However, they can come from casein (milk) too. Casein is a kind of milk-based protein, meaning it is not vegan-friendly.

Nevertheless, it is not mentioned in the energy drink, the exact sources of Tyrosine. So, we still can’t give you an exact answer yet.


Taurine is a popular amino acid that is found in many energy drinks as well as dietary supplements. It is also called sulfonic acid.

Taurine gives us a great energy boost by enhancing our energy levels and overall making us perform better. Sources of taurine are animals, to be direct, the bile of mammals.

Again, taurine can be synthesized in labs too.

The brand did not mention sources of taurine so we still don’t know where it comes from.


Choline is also an essential nutrient. Its sources are beef liver, eggs, nuts, fish, etc.

Choline is an important nutrient for the transportation of fat from our liver to inhibit cholesterol formation.

Choline also helps in asthma by reducing the risks of inflammation and swelling. It can furthermore help in muscle growth too, which is why it was probably used in Moose Juice.

Is Moose Juice Actually Gluten-Free?

It’s gluten-free.

A gluten-free diet can help significantly with weight loss.

So far, the energy drink doesn’t have any traces of wheat, barley, or rye. However, it has not been officially declared by the brand on whether it is gluten-free or not.

But since the drink doesn’t have any shreds of evidence of gluten, it can be said that Moose Juice is safe from gluten.

Does Moose Juice Have Any Side Effects?

Moose Juice doesn’t cause any major side effects unless you are downing 3 cans of Moose each day. Considering the drink is high-caffeinated, overconsumption of the drink will lead to possible side effects like:

  • Insomnia
  • Lack of appetite
  • Having headaches
  • Fatigue
Consuming too much caffeine might leave you feeling drained.

Besides the caffeine, keep the vitamin amount in mind too. As they are above their tolerable intakes, so that might lead to a vitamin crash, if you are not careful.

Flavours Of Moose Juice

Moose Juice has a variety of 5 different flavours, which are:

  • Mojito
  • Green Apple
  • Berry

The Bottom Line

Given the energy drink is offering 200mg of caffeine with no added sugar, that can be a good point for you to buy the drink if you are looking for something that has strong caffeine and no sugar. The calories are low too, only 20 calories each serving.

The vitamin content in the energy drink is, however, a little overwhelming. So in the future, the company should try working on it. That is just my personal opinion.

The drink is not certified as vegan-friendly. But it is gluten-free because no evidence of gluten-containing products was found in the energy drink.

Moose Juice overall is a great choice of energy drink.
