Brein Fuel Review (Tell All)

Brein Fuel Review (Tell All)

Brein Fuel is a performance-boosting beverage that contains L-Theanine, glycine, zinc, and creatine. Aside from that, it’s packed with naturally sourced caffeine from unroasted green coffee beans. This explains the main reason behind the energy boost in Brein Fuel.

It also has antioxidants like vitamin C, which can help prevent cell damage, and vitamin E and Beet Root. Of course, you have to try Brein Fuel to experience its goodness.

Here’s my verdict: Brein Fuel’s flavors aren’t that groundbreaking and its high caffeine content alone makes it a no-no for me and, I’d imagine, most consumers. I’d say that its strongest points are the micronutrients it contains and that the drink can be a good pre-workout for those who do heavy workout routines regularly.

If you want to learn more about the effects, flavors, and cost of Brein Fuel, keep reading.

Let’s start.

Who Owns Brein Fuel?

First off, Dr. Gerals Horn is a Lasik surgeon who developed Brein Fuel. He is a specialist in developing drugs and pharmaceutical science. Thus, he created Brein Fuel with proven ingredients to support physical and mental performance. 

Brein Fuel is an energy drink that boosts mental performance and productivity just like Ghost Gamer and X-Gamer. You can use it in gaming, workout, or meditation.

Brein Fuel Sugar Content

There is 4g sugar per bottle of Brein Fuel. Compared to other brands, that is a relatively small amount.

This is because Brein Fuel makes use of sucralose, an artificial sweetener that is much sweeter than natural sugar. Because the brand uses both natural sugar and sucralose, it tastes extra sweet. Especially its Citrus and Mixed Berry flavors.

Sweeteners are considered healthier alternatives because they are often calorie-free. In fact, energy drinks that use them are more suitable to be consumed by diabetics or those on diets.

If you’re still hesitant about artificial sweeteners in your drinks, I’m happy to report that they are FDA-approved. Besides, even this study stated that they’re beneficial for obesity and diabetics

Brein Fuel Caffeine Content

Brein Fuel has 360mg of caffeine. While caffeine is an effectively proven stimulant, this amount is so close to the FDA-suggested caffeine limit of 400mg per day. The amount is way higher than the amount I usually consume.

In fact, I prefer energy drinks that are within 50-100 mg of caffeine only since they give the right amount of energy without risking negative side effects.

If you consume a serving of Brein Fuel in the morning, that should be the only caffeinated product you should have all day. This means any tea, coffee, soda, or chocolate might give you a caffeine overdose. 

When I have more than 150mg of caffeine in a short time, I feel a bit anxious and jittery. Therefore, 360mg is off the charts and not something I’m looking for in my caffeinated drink.

Be careful with your caffeine intake.

360mg of caffeine in energy drinks can be dangerous if you’re highly sensitive to caffeine. If you’re caffeine-sensitive, there’s a high chance that you may experience the following:

  • Headache
  • Anxiety
  • Palpitations
  • Hallucinations

Brein Fuel Cost

If you buy on their official website, six-serving packs of any flavor would cost you around $24. The shipping fee around the United States will be free if you order $50 worth of Brein Fuel.

Here’s a 6-serving pack Brein Fuel.

With this amount, one bottle roughly costs around $4. I think the amount is too pricey for an energy drink. 

If you can afford its price, there are energy drinks that you can purchase for just a dollar. In fact, my go-to energy drinks only cost $1 per serving. I’ll tell you more about this later in this article.

Brein Fuel Flavors

Brein Fuel has four flavors. All of these have the same ingredients, including the 360mg of caffeine.

  • Peach Mango
  • Citrus
  • Fruit Punch
  • Mixed Berry

How Does Brein Fuel Taste? 

I want to tell you about the two of its flavors that really caught my attention. In my opinion, the Peach Mango flavor tastes like juice that has been in the fridge for a few days. It also has a hint of something akin to bitter medicine, especially as you swallow it. 

Based on its flavor alone, it gets 5/10 from me. However, even though its taste is not that good, some people may prefer this drink because of its other benefits. Therefore, I think my opinion on this flavor could differ from yours.  

Besides, I think it doesn’t taste as bad as some other top-rated products, such as 5-Hour Energy.

On the other hand, the Fruit Punch flavor has the taste of an opened juice that is still staying in the fridge for a little too long. It also has a pepper-like aftertaste. 

I’d give it 5/10, just like the Peach Mango flavor. I wouldn’t say I like its taste. But it’s not that bad, so I understand if some people rave about it. 

I think it tastes different from other energy drinks because of its different ingredients. Some elements are not present in other energy drinks and lack all of the B vitamins that give energy drinks their signature taste.  

While I believe that this is an excellent product for some people, I don’t think it’s something I’ll be craving. 

The most extensive factor is the 360mg of caffeine content per bottle. It’s just way too much for me, and I think people would feel the same.

Alternatives Energy Drinks

Because I prefer energy drinks with lower caffeine content, I think other energy drinks are safer to try than Brein Fuel.  

G Fuel

G Fuel has antioxidants that can protect your cells from free radicals. It’s pretty known to be effective on sports and athletic events because of its benefits and its deliciously fruity taste. 

Its flavors are mainly derived from a combination of several fruits. So if you’re a fruit lover, G Fuel might be the best energy drink for you. 

It’s also sugar-free, which means it won’t give you sugar crashes. It also has lower caffeine content than Brein Fuel, only 150mg. 


Rogue Energy is also another energy drink that’s ideal for gaming. It has no calories and no sugar. Aside from that, it also has nootropics elements that are good for concentration.

Additionally, it has amino acids, vitamins, and antioxidants that are good for your body. This will help boost your energy, alertness, concentration, mental clarity, and endurance.

There’s only 175mg of caffeine per can of this energy drink. Just imagine how much power you could get for just one serving. 

REIZE (The Best)

REIZE is a powdered energy drink packed with taurine, B vitamins, inositol, and ginseng. It’s a perfect energy drink because it only contains 50mg of caffeine.

If you have to restrict yourself from consuming Brein Fuel because of its caffeine, with REIZE, you can mix up to three servings while being safely within the FDA limit. But really, just one serving gives me everything I need for an action-packed day.

While Brein Fuel has 4g of sugar, this one is entirely sugar-free. It tastes gentle and citrus-like, making it unique to your taste buds. It’s also quite convenient to carry because it’s in a 4g sachet.

You can have it with cold or hot water, and it would still taste amazing. It would definitely give you the right amount of caffeine you needed, without jitters that could lead to drowsiness.

You can get REIZE for only around $1 per sachet. You can even have your orders delivered straight to your door. That’s amazing value for your money.

Try REIZE today and be energized like never before!

Other Notable Mentions

If you really want energy drinks with high caffeine content, you can also see the following:


Overall, this beverage will definitely be ideal for some people, but it’s not really up my alley. If you’re about to consume this energy drink, I’d just advise you to consume it in sips because that caffeine content is just sky-high.

I tried consuming one bottle of Brein Fuel, and in an hour, I experienced a significant boost of energy. However, I also experienced a little bit of rapid heartbeat. I think my body knows that Brein Fuel is just not the right fit.

In my opinion, there are just other brands out there that can safely provide a caffeine boost. Plus, the flavors of Brein Fuel aren’t that enticing to me.

All in all, I’d say that REIZE is still your best bet (God knows it’s mine) and I hope you give it a try!
