G Fuel VS Monster (Ultimate Showdown)

G Fuel VS Monster (Ultimate Showdown)

When it comes to energy drinks, G Fuel and Monster are two major outstanding brands. Both are effective at what they do, giving you strength and enhancing your concentration.

The primary goal of this blog post is to find out which one of these two energy drinks will come out on top if compared against each other. There is no straightforward solution to this for it’s all a matter of preference. I do have to say that both drinks contain a lot of added micronutrients, but G Fuel has more caffeine than Monster.

Join me as we look closer into the benefits and drawbacks of both brands! You’ll quickly discover which one suits your needs better.

Let’s get to it!

Ingredients in G Fuel and Monster

First, let’s take a closer look at the ingredients of both G Fuel and Monster listed below.

Mainly, the ingredients of G Fuel are divided into three parts, the energy complex, focus complex, and antioxidant complex. The three are broken down into the following:

  • Taurine
  • L-Citrulline Malate
  • Glucuronolactone
  • N-Acetyl-L-Carnitine HCl
  • L-Tyrosine
  • Choline Bitartrate
  • Adenosine-5 Triphosphate Disodium Salt (ATP)
  • Maltodextrin
  • Citric Acid
  • Silicon Dioxide
  • FD&C Blue #1
  • Cabbage Palm Berry Powder
  • Grape Seed Powder
  • Pineapple, Pomegranate, Apple, Orange, Blueberry, Grapefruit, Plum, Raspberry, Strawberry, Watermelon, Lemon, Lime, Melon, Sour Cherry, Papaya, and Peach Fruit Powders

On the other side, Monster is also composed of different nutrients, primarily with its core B-vitamins. The following are:

  • Carbonated Water
  • Citric Acid
  • Natural Flavors
  • Taurine
  • Sodium Citrate
  • Color Added
  • Panax Ginseng Extract
  • L-Carnitine L-Tartrate
  • Sorbic Acid
  • Benzoic Acid
  • Sucralose
  • D-Glucuronolactone
  • Inositol
  • Guarana Extract
  • Maltodextrin
  • Vitamin B2, B3, B6, and B12

Both of them are made up of different energy-boosting nutrients that work together to provide you with the energy you need to go through your day. Nevertheless, G Fuel appears to have a more nutritious formula than Monster and can provide more sustained energy.

Caffeine Amounts in G Fuel vs Monster

A 16-ounce can of G Fuel contains 300 milligrams of caffeine, while a 16-ounce can of Monster contains 160 milligrams of caffeine.

If you’re looking for a high caffeine boost, G Fuel is your best option. This means that this energy drink will assist you in staying awake for a prolonged period.

Please keep in mind that the 300mg of caffeine is relatively high. A single serving of Monster is already sufficient to help you work effectively in any activity, whether it is sports or gaming.

In my opinion, if you are used to high amounts of caffeine and live an active lifestyle, G Fuel is a good choice for you. However, if you’re just looking for a solid energy boost throughout the day, Monster will suffice.

Nevertheless, you must be aware of your daily caffeine intake limitations. The Food and Drug Administration advises that you consume no more than 400mg of caffeine per day and no more than 200mg of caffeine in a single afternoon.

Although caffeine has many benefits, consuming too much of it may result in severe health issues like caffeine overdose. Both G Fuel and Monster include a significant amount of caffeine, I recommend that you avoid going too much beyond your restrictions in any of them.

G Fuel Vs Monster

Aside from their caffeine levels, you should also take note of their sugar and calorie contents.


In comparison, Monster has a massive 54g of sugar per 16 fl. oz. can, while G Fuel contains no sugar at all.

In this case, Sucralose and Acesulfame Potassium are two artificial sweeteners used by G Fuel to sweeten the drink’s flavor. 

On the other hand, Monster has exceeded the daily added sugar restrictions for both men and women. The American Heart Association recommends that men and women consume 36g and 25g of added sugar, respectively, in a day.

If you drink a can of Monster, your health is already compromised, for you are already over your daily sugar allowance. Going over your daily sugar allowance every day can lead to either sugar crashes or increased blood pressure.

Fortunately, Monster launched a new variant of their brand, the Zero Ultra, a zero-sugar version of the drink. So, If you really like Monster but want to minimize your sugar consumption, Monster Zero Ultra is the drink for you.


G Fuel has no calories, while Monster contains 210 calories in a 16-ounce can.

For men and women, the recommended daily calorie consumption is 2,500-2,000 calories per day. On the other hand, this figure differs based on your age, gender, metabolic health, and level of physical activity you engage in.

Amazingly, G Fuel contains no calories, so it will not cause any weight gain, regardless of how you eat or how active you are. The serving size of Monster, on the other hand, has 210 calories.

Keep in mind that consuming Monster that is rich in calories and sugar may result in weight gain, obesity, or diabetes. If you decide to go with Monster, remember to drink responsibly.

Pros and Cons of G Fuel and Monster

For more information, here are the advantages and disadvantages that you will experience when having G Fuel and Monster.

Pros of G Fuel and Monster

First up, G Fuel contains nootropic nutrients. As a factor in the promotion of nootropic nutrition, G-fuel can give you exceptional performance during extreme physical activities.

Also, the antioxidant components contained in the drink help to prevent tissue injury caused by intense exercise. In the same way, antioxidants protect your cells from free radicals, allowing them to function at their optimum potential.

In G Fuel, there are no added sugars, and it is also gluten-free, making it a natural energy drink produced from natural fruit powders and other components that are low in calories.

In both its regular and low-calorie variants, Monster Energy Drink is an excellent provider of B vitamins. Including vitamins B2, B3, B6, and B12, a single serving provides 100 percent of the daily recommended intake.

The B vitamins are essential for obtaining energy from the foods you eat. Since they are water-soluble vitamins, they cannot be stored in your body, so you must consume a consistent supply to attain your daily requirements.

Cons of G Fuel and Monster

We’re now moving on to their disadvantages. Regarding their availability, G Fuel seems to be unavailable to many customers, particularly those in rural regions in which there is no network connection, while Monster is virtually everywhere.

Additionally, both contain additives such as artificial sweeteners and color. These ingredients are added to energy drinks to enhance their flavors, but they’re really not advisable to include in your diet daily, for they can have negative impacts on your health.

For Monster, there are some worries regarding the impact on health, particularly the belief that more is better, despite the fact that they provide certain health advantages and have low caffeine content. 

In a 2009 study published in The Annals of Pharmacotherapy, researchers discovered that a set of study participants increased their blood pressure and heart rate after consuming two cans of any energy drink. Accordingly, taking more than one can of Monster can trigger some health problems.

Alternatives to G Fuel and Monster

So here are a few alternative options to G Fuel and Monster that you might want to explore:

Red Bull

One 250-ml can of Red Bull Energy Drink has 80mg of caffeine, 110 calories, and 27g of sugar, all of which are considered moderate in quantities. Nevertheless, there are two other varieties of Red Bull that are sugar-free: Red Bull Sugar-free and Red Bull Zero.

Aside from those, this also includes a number of other nutrients, including taurine, glucuronolactone, B vitamins, and inositol. These components, used together, are thought to have beneficial benefits on mental ability, focus, and fitness levels.


Rockstar Energy Drink Original has 160mg of caffeine per 16-ounce can and 24g of sugar. In addition to caffeine, Rockstar Energy Drink includes several herbs, such as Panax ginseng, ginkgo Biloba, milk thistle extract, and guarana seed.

For the most part, this energy drink is designed to give a fantastic energy boost for people who have busy and active lifestyles, such as athletes and rockstars.

REIZE (Highly Recommended)

Finally, everyone’s favorite energy drink is here!

REIZE is sugar-free and has just 11 calories per serving while containing a reasonable 50mg of caffeine. In the form of 4g sachets, REIZE powdered energy drink emphasizes portability, making it even easier to take wherever you may need a pick-me-up. 

Aside from that, REIZE has a variety of helpful components such as taurine, ginseng, and B vitamins, which work together to give you the ideal energy boost without any of the terrible crashes.

You can even get REIZE delivered to your home for as little as around $1 per drink and you can have your orders shipped to your home too!

That’s a great deal.

If you consider giving REIZE a try, I’m confident that you’ll find it to be a more sensible alternative than G Fuel or Monster.

Final Verdict

Both energy drinks have their own set of benefits and disadvantages. Personally, I believe G Fuel is ideal for gamers, while Monster is suitable for physically active people.

In summary, G Fuel has 300mg of caffeine, whereas Monster contains 160mg, almost half as much as G Fuel. Monster has 54g sugar and 210 calories, while G Fuel contains neither sugar nor calories.

When you think about it, Gfuel and Monster both give you plenty of options to choose from. For example, Monster has 34 various flavors while G Fuel is available in a variety of flavors as well.

Indeed, Monster’s inclusion of high amounts of sugar and calories, as well as G Fuel’s 300 mg of caffeine, can cause a  lot of dangers to your health, so I don’t think that they will be good for you in the long term. However, once again, the decision on which energy drink is the best is entirely up to you. 

And what about me? I think REIZE is the greatest of them all since it has the least amount of caffeine, without calories or sugar, but still has all the beneficial effects G Fuel and Monster offers.
