G Fuel Vs C4 Energy (Who Wins?)

G Fuel Vs C4 Energy (Who Wins?)

G Fuel and C4 are two famous brands that cater to gamers and athletes alike. They don’t differ much in caffeine content. As you may know, C4 has 200mg of caffeine, while the canned version of G Fuel contains 300 mg.

C4 Energy is a sugar-free energy drink enhanced by Beta-Alanine, BetaPower, and other elements. These are all for energy, mental alertness, muscular strength. 

In the same way, G Fuel is also sugar-free, with zero calories. It’s made as a physical performance enhancer ingredient like B-Vitamins and antioxidants.

C4 is for all kinds of athletes, but G Fuel is created ideally for gamers. While you can use both interchangeably, you may wonder how exactly do they differ from one another?

Unlike their zero-sugar property, these two have different levels of caffeine and vitamins. While some of their ingredients are the same, they differ in amount. 

Read further to this article as I detail their similarities and differences.

Let’s get going.

Nutritional Information of G Fuel and C4

As you can see, they almost look alike except for the fact that G Fuel has Vitamin B3 and sodium. Sodium is a form of electrolyte, but so is potassium. 

Fortunately, they have the same amount of potassium. 85mg of potassium may look a lot. Just to give you a piece of extra information, don’t you know that you need to consume 3,500–4,700 mg of potassium in your body to be a healthy adult.

Does G Fuel Really Give You Energy?

If you’re talking about energy from their calories, unfortunately, you won’t get any. I understand that calorie is a big help in choosing what products or beverage can give you more energy.

Even though G Fuel and C4 lack calories, they can still provide you with power through their other contents.

Caffeine can help you regarding this matter. Although caffeine is not a direct energy source, it’s still a good stimulant

Both of the energy drinks contain a decent amount of caffeine, so they can provide you with a decent amount of energy to get going. However, you should always consume caffeinated products in moderation.

G Fuel vs. C4 Side-Effects

The side effects of these products have something to do with caffeine. The FDA strongly suggests that you should only allow a maximum of 400mg of caffeine per day in your body. This means that more than a can of C4 and especially G Fuel can lead to serious side effects.  

These are some signs of caffeine overdose:

  • Trouble breathing.
  • Vomiting.
  • Hallucinations.
  • Confusion.
  • Chest pain.
  • An irregular or fast heartbeat.
  • Uncontrollable muscle movements.
  • Convulsions.

On the other hand, you won’t overdose with sugar in G Fuel or C4 as they don’t have any. They use sucralose and acesulfame potassium. These two artificial sweeteners are both approved by the FDA. In fact, it’s so safe that there has been a study conducted that shows these two artificial sweeteners are beneficial for people with diabetes. 

C4 Energy can.
Here’s how C4 Energy Looks.

Sucralose can make C4 and G Fuel a lot sweeter than natural sugar. On the other hand, acesulfame potassium doubles the effect of sugar on taste.

You’ll have an idea of how sweet G Fuel and C4 are in their flavors by looking at the names of their unique line. 

G Fuel vs. C4 Flavors

These are all from the line of G Fuel. The following are also available in the powdered version:

  • Blue Ice
  • Rainbow Sherbet
  • Sour Cherry
  • FaZeberry
  • Sour Blue
  • Bahama Mama
  • Raging Gummy
  • Nemesis Tea
  • Tropical Rain

If your desired flavor isn’t available in the canned version, you can check if it’s available in their tubs. Meanwhile, C4 can give you more options in terms of flavor:

  • Frozen Bombsicle
  • Strawberry Watermelon Ice
  • Tropical Blast
  • Twisted Limeade
  • Arctic Snow Cone
  • Cherry Limeade
  • Cotton Candy
  • Midnight Cherry
  • Orange Slice
  • Purple Frost
  • STARBURST Cherry

G Fuel vs. C4 Cost

Lucky for you, their price doesn’t change regardless of the flavor you choose. However, the prices of G Fuel and C4 and quite far from each other. Who do you think is most cheaper? 

Let’s start with G Fuel. You can get a 6 Flavor Variety Pack on Amazon for about $45. That means that each one can have a value of $3.75. 

In my opinion, this price is quite costly for an energy drink. On the other hand, C4 energy is priced at $26 per 12 cans. Obviously, when it comes to price, C4 is much more affordable. You can have a can for around only $2, which is quite cheaper than one can of G Fuel.

Alternatives Energy Drinks

Aside from C4 and G Fuel, some energy drinks are somewhat of the same caliber.


Reign is also included in the list of the strongest energy drinks widely used. It has electrolytes like sodium and potassium, which can help you replenish your lost fluids during exercises.

This energy drink also has vitamins and minerals that are good for your skeletal function, such as magnesium and calcium.

Before I forget, Reign has 300mg of caffeine. Because of this I highly suggest you consume only one can per day.

Ghost Gamer 

If you take a look at the label of Ghost Gamer, you’ll already notice that it has vitamin B and C with no added sugar. If you haven’t tried this energy drink yet, you can order a sample on their website and try it for free. 

If you want the 150mg of caffeine experience from C4 energy, you can go with Ghost Gamer. However, it depends if you want an energy drink made for gamers like G Fuel cans.

REIZE (My Favorite)

While G Fuel Cans are fabulous, I think its 300mg of caffeine isn’t ideal for everyone. With REIZE, you can be sure that it won’t give you headaches or nervousness at all. 

REIZE comes as a powdered energy drink in a convenient 4g sachet. This means you can carry it in your pockets and mix it in any container you desire. 

Its caffeine is only at 50mg, perfect for a moderate lift. It’s also sugar-free and has only 11 calories, which will be easy to burn.

Other Notable Mentions


In conclusion, C4 and G Fuel have many similarities. They primarily differ on other vital nutrients, taste, and cost. For me, G Fuel is a little better than C4. 

However, I honestly believe both are energy drinks that you can enjoy. Just remember to keep an eye on your caffeine intake and settle with the one who doesn’t make you feel any side effects.

If you’re on a budget, I suggest going with C4. This is because you can get three cans of C4 Energy for the price of two cans of G Fuel.

On the other hand, if you want to know how G Fuel tastes and you still have the money, it wouldn’t hurt to indulge from time to time.

Nevertheless, whichever you prefer, always limit yourself to one can of energy drinks per day to maximize their benefits and avoid side effects.
