Are you considering switching from the powdered G Fuel to the canned version? This popular ready-to-drink version of G Fuel is, without a doubt, the easier and more convenient alternative to the classic G Fuel tub.
But what exactly do you get from canned G Fuel? And how much nutrition can it give you?
For the short answer, a regular 16 fl. oz can of G Fuel is both calorie and sugar-free, has natural ingredients such as minerals and vitamins, but has up to 300mg of caffeine in it.

How Much Caffeine Does A G Fuel Can Have?
A regular serving of a 16 fl. oz G Fuel Can contains 300mg of caffeine, which gives it a spot in our strongest energy drinks category.
Caffeine has been noted to provide a whole host of benefits, ranging from helping you stay alert, improving cognitive functions, and of course, keeping you awake.
Although there isn’t an explicit limit to how much caffeine a drink can contain, a study states that the recommended limit of caffeine for over-the-counter products shouldn’t be more than 200mg.
G Fuel offers twice as much caffeine as its powdered tub counterpart, so keep that in mind if you’re thinking about buying a can (300mg vs. 150mg).
However, it all comes down to your caffeine tolerance and sensitivity. If you’re someone with a high caffeine tolerance, then G Fuel will surely give you the boost of energy you need.
Personally, I prefer my energy drinks to have around 50 to 100mg of caffeine per serving, which is just the right amount to give me the energy boost I’m looking for without worrying about the side effects.
Just be sure to keep in mind the side effects of consuming too much caffeine as healthy adults are allowed a limit of 400mg caffeine per day, according to the FDA.
Over-consumption might lead to side effects such as:
- Anxiety
- Dizziness
- Insomnia
- Abnormal heart rate
- Dehydration
- Headaches
- Restlessness and shakiness
- Stomach problems
Also, it is wise to limit your caffeine intake by sticking to only one G Fuel can per day (if you’re planning to get one) and try not to accompany it with any other caffeinated beverages, as that might tip you over your limit.
How Much Sugar Can A G Fuel Have?
G Fuel Cans contain zero sugar, as the brand prides itself on providing sugar-free energy drinks, which is a refreshing difference from other sugary energy drinks.
If you’re looking for an energy drink that can help you monitor your daily sugar intake, then G Fuel Cans may be right up your alley.
According to the AHA, the daily max limit of sugar for females and males is 25g and 36g, respectively.
As with caffeine, over-consumption of sugar can be damaging to your health, which, fortunately, isn’t a concern with G Fuel. However, you won’t get the sweet flavour and the dopamine rush that comes from sugar.
Personally, I’d say it’s a fair trade given their high caffeine level. But this is not to be confused with the artificial sweeteners in a G Fuel can.
If you enjoy sugar-free energy drinks but dislike G Fuel Cans’ high caffeine content, take a look at the article I’ve written on the best sugar-free energy drinks for some great alternatives.
Do G Fuel Cans Use Artificial Sweeteners?
A G Fuel Can contain artificial sweeteners such as sucralose and acesulfame potassium despite containing zero sugar.
The presence of artificial sweeteners in G Fuel is used to add a little sweetness to the drink. Otherwise, it wouldn’t taste as pleasant, as zero sugar means no sweet flavour.
The use of artificial sweeteners may be a welcomed change, especially if you’re controlling your sugar intake because sucralose and acesulfame potassium are both calorie-free sweeteners.
Although there are still some controversies surrounding the use of artificial sweeteners, you needn’t be too concerned as they’ve been approved for general consumption by the FDA.
Maltodextrin In G Fuel Cans
Besides artificial sweeteners, G Fuel Cans also contain Maltodextrin, which works as a thickening agent, extending the shelf life of the drink.
Maltodextrin essentially gives a thicker volume to your food or drink, which allows it to have a longer shelf life. A fair warning though, this ingredient may be harmful to you if you’re diabetic.
The reason being so is that maltodextrin can still increase your blood sugar levels (it even has a higher Glycemic Index than sugar), even if it says it only adds a dietarily insignificant amount of sugar to your food.
If you’re looking for a drink that’s safer for diabetics, have a quick look at an article I’ve written previously on the best energy drinks for diabetics.
Are There B-Vitamins in a G Fuel Can?
Like many other energy drinks, B-Vitamins can also be found in G Fuel Cans, albeit in a lower amount compared to its powdered version.
Here’s a table I made that lists down the relevant B-Vitamins you can find in a G Fuel Can and its powdered version, and if you need more information on them, click here.
| Purpose | Helps the body release energy, Keeps skin healthy | G Fuel Powder (7g) | Tolerable Upper Intake Level | |
| Vitamin B3 (Niacin) | triggers the body to release energy promotes healthy skin | 4mg | 45mg | 35mg |
| Vitamin B6 | produces amino acids forms all new cells in the body | 0.4mg | 10mg | 100mg |
| Vitamin B12 | processes carbohydrates to energy produces amino acids | 0.6µg | 425μg | N/A |
Do G Fuel Cans Have Lead?
G Fuel products contain lead due to their ingredients, such as vitamins and minerals, being naturally sourced. That being said, it still falls well below the FDA’s limit for lead.
If you’re specifically wondering about the lead content of G Fuel Powder, I’ve written about it in my G Fuel Review article.
Back to G Fuel Cans, the FDA sets the daily limit of lead to 75.0mg for an adult and 6.0mg for children. With a quick Google search, you can find that G Fuel falls under the limit with only 0.5mg.
The presence of lead, especially in vegetables and fruits, is natural as it comes from the soil. Thus, making it traceable in our food supply.
This happens because:
- The soils that we use to plant vegetables and fruits contain lead.
- Lead found in plants cannot be completely removed.
- Animals that we consume have lead including their dietary.
In short, lead is present in naturally produced products and cannot be removed from the environment.
Additionally, G Fuel Cans don’t contain the same lead warning label that G Fuel Powder has. This means even if G Fuel Cans did contain lead, it would be in very small trace amounts that won’t be harmful to your body.
Are G Fuel Cans Bad For Your Health?
Like most other energy drinks, G Fuel Can isn’t harmful to your health as long as you be mindful of your daily intake and lead a healthy lifestyle.
While it’s undeniable that G Fuel has a high caffeine level comparable to some of the strongest energy drinks, it also provides you with a good amount of antioxidants that neutralise free radicals.
This then helps reduce the risk of major health problems like heart disease and cancer.
According to its official website, G Fuel is generally suitable for healthy individuals, but if you’re still unsure, you should consult a health professional before adding it to your diet.
G Fuel Can Benefits
The benefits of G Fuel Cans include providing an energy boost and improving brain performance, which makes it suitable for gamers and athletes.
I’ve also listed down the other benefits of G Fuel Cans:
- It contains natural ingredients and is sugar-free, which can help lower risks for health problems like heart disease and diabetes.
- It has antioxidants that help boost your immune system and protect your cells from free radicals.
- It helps boost your brainpower, giving you the ability to focus more and improve your memory.
- It only takes up to 15 minutes for the effects to kick in, but the energy boost you get can last you 4-6 hours, while also being sugar-crash-free after the effects wear off.
What Are The Side Effects of G Fuel Cans?
The most significant side effects from drinking G Fuel Cans can mostly be attributed to their high caffeine level.
As mentioned previously, this drink relies heavily on caffeine, which can be harmful if you aren’t monitoring your daily intake.
Also, it’s best to make sure you have your health in check if you plan on including it in your diet, and not go overboard when drinking G Fuel Cans.
Although it leans more on the healthier side of energy drinks, drinking too much caffeine is never a good thing.
G Fuel Cans Drink Alternatives
If you think G Fuel Cans are not for you, here are some other great alternatives for you:
If canned energy drinks aren’t for you, maybe you’d prefer powdered energy drinks instead. Not only are they more affordable and easy to prepare, but they also offer more control of your own energy drink:
- ZipFizz
- Advocare Spark
- REIZE (highly recommended)
