G Fuel Energy Fuel Facts

G Fuel is an energy formula initially created to keep online gamers “focused and energized.”

Gamma Labs launched the G Fuel product range in 2012 with three flavors, Blue Ice, Fruit Punch, and Lemon Lime. It became a popular drink in the eSports and online gaming industry. 

These days, there are different types of G Fuel available in over 40 different flavors. Not only gamers use this product. Gamma Labs market it as a drink for people like UFC fighters, bodybuilders, fitness models, NFL players, and YouTube stars.

The types of G Fuel in a variety of flavors include:

  • G Fuel Energy Formula
  • G Fuel Energy Cans
  • G Fuel Hydration Formula
  • G Fuel Sparkling Hydration Formula

The company aims to create sugar-free energy products fortified with antioxidants and vitamins to fuel focus, energy, reaction time, and endurance. 

One of its competitors is Red Bull which is another energy drink.

Main Ingredients

Each serving of the G Fuel Energy Formula contains 140 mg of caffeine, antioxidants, amino acids, vitamins C, E, B6, and B12, and energy and focus-enhancing formulas.

The G Fuel Energy drink cans contain 300 mg of caffeine, zero sugar, and zero calories. 

The G Fuel Hydration Formula and Sparkling Hydration bottles are free from caffeine and sugar and contain amino acids, vitamins, and electrolytes.

Here are some of the major ingredients found in G Fuel products is you can decide is G Fuel is bad or okay for you.


the word caffeine on a blackboard over a chalk drawing of the compound.

Caffeine is a natural stimulant derived from coffee beans, tea leaves, and cacao plants.

Research has linked moderate caffeine consumption to a reduced risk of liver cancer, among many other excellent health benefits. It may help ward off heart failure, lower your risk of Parkinson’s and Alzheimer’s disease, and protect against DNA damage. 

But despite all of these fantastic advantages, it’s important to remember that caffeine is a stimulant, and you should exercise caution when consuming it regularly. Too much caffeine can negatively affect heart rate, those with high blood pressure, and may lead to caffeine overdose if you drink too much.

Most healthy adults can safely consume up to about 400 mg of caffeine per day. One serving of G Fuel have about 150 to 300 mg per serving which is considered to have a high caffeine content and potentially negative side effects.

According to the American Academy of Pediatrics, children should not have caffeine. Most of the G Fuel products contain caffeine which can increase energy levels temporarily. 


L-tyrosine is a non-essential amino acid. Your body produces it, so you don’t have to get it from food.

It helps the brain build chemicals that influence mood. It also helps produce melanin, a pigment that colors hair and skin. If you need to supplement this in your diet, you’ll find it in meat, fish, dairy products, eggs, nuts, beans, wheat, and oats. 


Sucralose is a synthetic sweetener made from sucrose. The body can’t metabolize it, and it is chlorinated.

Research shows that long-term use can have a toxic effect on the body and can change your gut microbiome by lowering good bacteria. It can also increase inflammation, leading to problems like diabetes and obesity.

Sucralose is not considered a healthy ingredient and should be used cautiously or avoided altogether due to its potential to lead to health problems (although the Food & Drug Administration has not banned it).

Sucralose is also known as Splenda and is one of the artificial sweeteners that you may wish to avoid.

Silicon Dioxide

Silicon Dioxide is a common food additive made from silica and oxygen, two naturally occurring elements. It is present in plants like leafy greens, bell peppers, brown rice, beets, and oats.

In processed food and supplement production, silicon dioxide is an anti-caking agent, disintegrant, and absorbent.

Research has not conclusively proven that silicon dioxide harms human health, but there are also no significant health benefits.

Taurine is a conditional amino acid naturally present in the body and is found in eggs, meat, and fish. It can help support muscle maintenance and heart health.

If your diet includes animal products, you could already be getting additional taurine through your food.

Nutrition Pros

G Fuel does not contain any added sugars, and it’s gluten-free.

G Fuel Hydration Formula and Sparkling Hydration contain electrolytes and fewer processed ingredients than the other products. 

Nutrition Cons

Besides the G Fuel Hydration Formula, all other G Fuel products contain caffeine and artificial food dyes, including FD&C Yellow #6 and FD&C Red #40.

All G Fuel products contain artificial flavors and sweeteners like sucralose, which has several potential health risks. People with Graves disease or an overactive thyroid should avoid consuming products that contain L-Tyrosine.

There’s also a California Proposition 65 lead warning for this brand. Gamma Labs explains that the warning is because of trace amounts of lead because of some ingredients being grown in soil and that California has far more stringent laws than the FDA. It’s up to you to decide how you feel about these warnings. 

The bottom line is that this product contains too many artificial and troublesome ingredients to be consider part of a healthy lifestyle. Better alternatives include real food ingredients with natural ingredients such as coffee or tea.

That said, it’s a good idea to avoid sugar-loaded energy drinks as well. If you need more energy and focus, you may wish to try supplements that have a vitamin B energy complex or ruling out other health issues. Speak to your healthcare provider if you are concerned about feelings of low energy or if you need a dietary supplement.

Not everyone should drink G Fuel. Children and people sensitive to caffeine should avoid caffeinated G Fuel products.

People with Graves disease or an overactive thyroid should avoid consuming L-Tyrosine products.

Consuming too much sucralose can cause adverse health effects for anyone over time.

Will I get a sugar crash from G Fuel?

No, G Fuel contains no added sugar, so you won’t experience that. However, it contains sucralose, a sweetener that may have adverse effects on your health over time. 


G Fuel is a highly processed product with very few nutritional pros. It does not contain any added sugars, and it’s gluten-free. The downside is that it contains many unhealthy artificial ingredients, some of which can harm people with certain health conditions.

Some G Fuel products have a high caffeine content, so they won’t be suitable for children or people sensitive to caffeine. For an energy boost or improved concentration, it’s best to consume real whole foods instead of processed products.
