Is G Fuel Safe? (Facts)

Is G Fuel Safe? (Facts)

G Fuel is an energy drink made by Gamma Labs, which is specifically targeted toward the gaming community that’s also advertised to be more healthy and clean than energy drinks that are high in sugar.

While all that may convince you into buying G Fuel Energy Drinks, let’s answer the question: Is G Fuel safe for you?

G Fuel is made with safe ingredients and has only moderate caffeine and no sugar. It also contains B Vitamins and Vitamins C and E, which are all beneficial to your health. However, G Fuel does contain trace amounts of lead, which have been deemed as not harmful.

That being said, G Fuel does have its flaw, which is why the question deserves more than just a “yes” or “no”. So let’s dive a little deeper from its ingredients to its caffeine content, then decide just how safe it is for you.

G Fuel Nutrition Facts

How Many Calories Are In G Fuel?

G Fuel Powder has around 10 to 25 calories per 7g (12-16 fl.oz) serving, while G Fuel Cans have no calories at all.

If you consume G Fuel Powder moderately, its calorie content won’t affect your diet drastically as the recommended daily caloric intake is around 2000 to 2400 calories for women and 2400 to 3000 calories for men.

Given that the G Fuel Can is calorie-free, this makes either one of them suitable to be included in your overall diet plan.

But if you’re looking at it from a more nutritional perspective, G Fuel relies mainly on caffeine to give you an energy boost which means your cells won’t be getting any substantial amount of energy to burn off.

That said, G Fuel (including other calorie-free energy drinks) doesn’t give you ‘energy’ in the scientific sense despite being marketed as an energy drink.

So, you should eat a proper meal when you’re planning on drinking G Fuel to experience the full benefits it offers without the unnecessary crash from lack of calories afterward.

G Fuel Ingredients

G Fuel Powder

G Fuel Powder contains an interesting blend made of multiple complexes, and other ingredients that are claimed to be good for you.

Have a quick look at the ingredient label on the back of a G Fuel Powder tub below:

Of course, if you wish to read a more detailed analysis of all the ingredients in G Fuel Powder and what exactly do they offer you, check out this article I’ve written on that very topic.

G Fuel Cans

On the other hand, here are all the ingredients that can be found in a G Fuel Can:

  • Carbonated Water
  • Natural and Artificial Flavors
  • Sodium Gluconate
  • Malic Acid
  • Caffeine (Purecaf™)
  • Potassium Beta-Hydroxybutyrate (goBHB®)
  • Vitamin Blend (Maltodextrin, Vitamin C, Vitamin B3, Vitamin B6, Vitamin B12)
  • L-Tyrosine
  • Sucralose
  • Potassium Citrate
  • Acesulfame Potassium
  • Antioxidant Blend (Green Coffee Bean Extract, Green Tea Extract, Turmeric Extract, Tart Cherry, Blueberry, Broccoli, Kale)
  • L-Theanine
  • Steviol Glycosides

If you want to know more about the caffeine and ingredients in G Fuel Cans, I’ve also written an article on that topic which you may find interesting.

How Much Caffeine Is In G Fuel?

While Fuel Powder’s caffeine content is at 150mg per 12 to 16 fl.oz, G Fuel Cans have double that amount with 300mg of caffeine per 16 fl.oz.

Almost a must-have, energy drinks consist of caffeine, which is why you feel more awake whenever you drink them. They also help improve your overall cognitive performance.

The caffeine content in G Fuel Powder seems rather normal for an energy drink as the caffeine content in energy drinks can range from 80 to 300mg of caffeine per serving.

The amount of caffeine present in G Fuel Cans, on the other hand, seems to be very high, making its way in the list of some of the strongest energy drinks.

It’s also important to note that it all comes down to your caffeine tolerance and not so much on the amount of caffeine present.

You should think about how much caffeine your body can manage before reaching for a caffeinated beverage. In this method, you won’t have to worry about any unwanted side effects.

Personally, I prefer my energy drinks to have around 50 to 100mg of caffeine per serving, which is the ideal amount for me, increasing my energy without the crash after.

Besides that, another great thing about G Fuel Powder (or powdered energy drinks in general) is that you can control the servings, which I find beneficial especially if you have specific preferences.

That said, it is recommended by the FDA that you consume no more than 400mg of caffeine per day, and over-consumption of caffeine can lead to some serious health issues like:

  • Insomnia
  • Restlessness
  • Headaches
  • Stomachaches
  • Dizziness
  • Dehydration
  • Anxiety

My advice is to maintain a healthy limit when you’re planning on drinking G Fuel and avoid combining it with other caffeinated beverages (tea, coffee, sodas) on the same day.

How Much Sugar Is In G Fuel?

Both G Fuel Powder and G Fuel Can are completely sugar-free.

The lack of sugar in G Fuel Energy Drinks will help you avoid the dreaded sugar crash that’s caused by the sudden spike and drop in your blood sugar levels, which makes you feel slow and lethargic.

To add on, excessively consuming sugar can be damaging to your health as it leads to consequences, such as:

  • Acne
  • Decreasing Dental Health
  • Weight Gain
  • Type II Diabetes
  • Increased risk of Heart Disease
  • Increased risk of Depression

Fortunately, G Fuel cancels out those risks for you as it doesn’t contain any sugar, and I think it’s a fair trade though you’ll be missing gaining easy calories and a taste of that sweet ol’ dopamine rush.

If you’re looking for more options for sugar-free energy drinks, I suggest that you look at the article I’ve written on the best energy drinks without the crash. You might find yourself some great alternatives.

Does G Fuel Use Artificial Sweeteners?

Not sure if these have artificial sweeteners but I’d sure love me some donuts

G Fuel contains artificial sweeteners, namely Sucralose and Acesulfame Potassium, to substitute the sweet flavoring that’s absent, being sugar-free.

Artificial sweeteners are 200 to 600 times sweeter than sugar itself, acting as a food flavoring, not adding any nutritional value to the drink, being completely calorie-free so you can enjoy the sweetness without the guilt.

While artificial sweeteners are FDA approved, let’s keep in mind that they’re still plenty that we don’t know of the use of artificial sweeteners in our food production.

My advice is, make sure to take note of the amount of artificial sweetener in your energy drink and moderate your intake.


If you haven’t read my article on G Fuel Cans, you’re probably wondering: what is Maltodextrin?

In short, Maltodextrin is an additive and is used to thicken and preserve the food product.

Just like artificial sweeteners, Maltodextrin is approved by the FDA and is safe to use. That said, it does have a rather high rank on the Glycemic Index (GI) scale.

This may cause a higher spike in blood sugar than regular sugar would.

That said, if you have diabetes, it’s best to avoid or consult your doctor before trying out G Fuel as there’s a possibility of a blood sugar spike.

If you happen to be diabetic and don’t want to risk the maltodextrin content, have a look at my article on the best energy drinks for diabetics, and you might find an energy drink that suits you better.

Is There Lead In G Fuel?

Despite the warning label, G Fuel doesn’t contain any significant traces of lead, and isn’t a worrying factor for the drink.

Now, that’s pretty scary

So far, G Fuel seems like a reliable energy drink, but I have to admit that its warning label does raise a few concerns over the possibility of lead exposure from the drink.

It’s only fair that you’re planning on getting rid of G Fuel immediately after hearing that but first, have a look at what Gamma Lab’s CEO (creators of G Fuel) said about it:

From above, it appears that G Fuel comes with a lead warning to abide by the strict Californian Law (Safe Drinking Water and Toxic Enforcement Act of 1986), which makes it less of a health-related issue.

And just like that, your worries are gone!

Is G Fuel Safe?

Yes, G Fuel (both the powdered and canned version), is safe to consume as long as you’re healthy and are mindful of your daily caffeine intake.

As I’ve previously stated, G Fuel’s sole source of its energy-boosting property is its caffeine, which helps improve your focus, especially if you’re pulling an all-nighter.

However, if you experience any side effects, chances are, your body isn’t able to tolerate its caffeine content. In that case, you should go for an energy drink with a lower amount of caffeine in it.

To be perfectly safe, you should consult your health specialist first if you’re planning on including energy drinks in your diet, especially if it’s your first time.

In conclusion, when consumed in moderation, G Fuel is definitely beneficial for you whether you need the energy to kickstart your mornings or during those long-hour gaming sessions.
