Calories In G Fuel Powder

G Fuel Powder contains 25 calories per serving. The amount of calories in G Fuel Powder is lesser when compared to other energy drinks such as Monster (210 calories per 16 fl. oz. ), NOS (210 calories per 16 fl. oz. ), and Venom (210 calories per 16 fl. oz).

Calories can measure all of the energy you get from food or drink. It’s often necessary for people to take proper account of it to maintain their health.

Men should have 2400 to 3000 calories per day, and women should have around 2000 to 2400 calories per day. This is the daily requirement of calories required by your body to fuel metabolism. And a surplus of that can lead to obesity, cancer, or other chronic health problems.

One scoop of G Fuel will add only a few calories to your daily calorie intake and you don’t have to worry about these. Furthermore, if you’re trying to lose weight, incorporating this drink into your daily meal plan will be simple.

How Much Caffeine Is In A Serving Of G Fuel Powder?

Caffeine content
A cup of coffee contains 40 mg of caffeine

There is 150mg of caffeine in G Fuel Powder which is very moderate.

Caffeine is added to energy drinks because it stimulates your brain and helps you focus. This is why having energy drinks keeps you alert and decreases your reaction time.

FDA reports suggest that an average of 400 mg of caffeine per day is safe for adults. And consuming more than that makes you experience the following side-effects:

  • Headache
  • Insomnia
  • Jitters
  • Nausea
  • Anxiousness
  • Rapid heart rate
  • Stomachache

The caffeine content of G Fuel energy powder is quite reasonable compared to G Fuel Energy canned version (300 mg) or Bang (300 mg).

But if you have very little tolerance for caffeine or simply like low-caffeinated drinks, you may try Red Bull which has only 80 mg of caffeine.

Sugar and Artificial Sweeteners In G Fuel Powder

G Fuel powder contains no added sugar, but it does have two kinds of artificial sugars named Sucralose and Acesulfame potassium or Ace-K.

Artificial sweeteners are sugar substitutes that add sweetness to food or beverages but have no nutritional value. And most of these chemicals are FDA approved, Sucralose and Acesulfame Potassium are on the list.

The following are the two most important health benefits of artificial sweeteners:

  • They help you lose weight as you’re not intaking sugar which has nutritional value.
  • They are diabetic friendly because they’re not carbohydrates and don’t raise blood sugar.

Some studies have found that artificial sweeteners affect the healthy microbiota of your gut, which are responsible for preventing infections. Other studies also claimed that it increased risks for obesity, type 2 diabetes, heart disease, and metabolic syndrome.

Sucralose can be about 400-700 times, and acesulfame potassium is 200 times sweeter than table sugar. Ace-K has a bitter taste that you probably won’t taste due to the presence of several ingredients.

Both sweeteners have very little or no impact on your blood sugar or insulin levels.

Other Ingredients In G Fuel Powder


Taurine is an amino acid required abundantly in the muscles or brain tissues. And it is commonly used in energy drinks due to the following health benefits:

  • Aids in sports performance
  • Regulates immune system
  • Maintains hydration
  • Controls blood sugar levels
  • Reduces risks for heart diseases
  • Improves eye-sight
  • Reduces fatigues

G Fuel powder contains taurine, which will help athletes and gamers perform better. However, estimating its efficiency is tricky because we don’t know how much is in the drink.


Maltodextrin is a powdery carbohydrate that thickens the food/drink and increases shelf-life. It is mostly made from rice, wheat, tapioca, or potato. The powder itself is tasteless but can improve the flavor or texture of the product.

It’s FDA approved and considered to be Generally Recognized As Safe (GRAS). And it is used in energy drinks because it provides rapid energy, as it gets metabolized easily.

People with diabetes should avoid Maltodextrin because studies have shown it can significantly increase blood sugar levels. Moreover, similar to artificial sugars, they can also affect your gut flora.

L-Citrulline Malate

L-Citrulline Malate is a lesser-known ingredient. It’s primarily used in energy drinks because, like many other ingredients, it improves athletic performance.

This amino acid can be converted to certain components which are required by your body. It also widens blood vessels to reduce blood pressure.

Focus Complex Of G Fuel Energy Powder

The Focus Complex contains L-Tyrosine, N-Acetyl-L-Tyrosine, and Choline Bitartrate. They mostly improve your mental strength and keep you alert.

L-Tyrosine and N-Acetyl-L-Tyrosine

Apart from Taurine, Tyrosine or L-tyrosine is another amino acid found in G Fuel Energy Drink. N-Acetyl-L-Tyrosine is just a more soluble form of Tyrosine that makes the powder more dissolvable.

The main function of Tyrosine is to make neurotransmitters for passing impulses in the nervous system. It powers up your brain, helps you take faster actions, and improves your cognitive functions during stressful situations.

Furthermore, the FDA has determined that the use of Tyrosine is safe.

Choline Bitartrate

The liver produces choline, which is required for the formation of acetylcholine, a neurotransmitter. Because your body does not produce enough of it, you must obtain some through diet.

Other bodily functions played by Choline are:

  • Improves cognitive functions
  • Metabolism of fats
  • DNA synthesis
  • Reduces risks for ischemic stroke
  • Keeps heart healthy

Healthy adults must not take more than 3.5g of Choline daily due to some side effects like low blood pressure, vomiting, heavy sweating, or liver damage.

Vitamins and Antioxidants In G Fuel Powder

G Fuel powder has the following vitamins:

Vitamin EPrevents blood clot, boosts immune system
Vitamin CStress release and beautiful skin
Vitamin B3Reduces cholesterol and detoxifies the blood
Vitamin B6Boosting of immune system prevents anemia, improves mood.
Vitamin B12Energy boosts renew skin and help to recover from fatigue.

They help to decrease the chances of getting cancer and many other diseases. Vitamin E and C are also antioxidants.

Is G Fuel Powder Bad For You?

I believe there’s nothing to worry about if you drink G Fuel in moderation.

Let’s compare the drink’s content with the daily limit:

ContentG Fuel Powder (7g)Daily Limit
Calories25 calories2500/2000 calories
Caffeine150 mg 400 mg
Sugar0 g36/25 g
None of the contents seem to be exceeding the daily limit

If you plan on making this drink regularly, you won’t have to worry about sugar or calories. Caffeine content is also very moderate, yet overindulgence will be harmful.

And consider this drink according to your physical activity status. Ask yourself, how much energy do you really need?

How Much G Fuel Powder Can You Drink In A Day?

Tub, Label, Energy drink
Directions for mixing

It’s better if you limit to only one serving of G Fuel Energy Powder in a day.

You might not want to get dependent on caffeine or suffer from caffeine overdose. Because throughout the day, we do consume caffeine from other sources like tea, coffee, or chocolate.

As a result, there is a chance that we will exceed the daily limit (400 mg) without even realizing it. To be on the safe side, one serving is sufficient.

Final Thoughts

G Fuel Energy powder is extremely potent while also being healthy and high in antioxidants. Gamma Lab has worked hard to make the focus and energy complexes as simple to use as possible.

The caffeine content of the drink is ideal for me. It keeps me going throughout the day without making me jittery. But I wouldn’t recommend drinking more than one serving per day.
