Brein Fuel Caffeine and Ingredients (Detailed)

Right off the bat, Brein Fuel promises to be a unique “cerebral beverage.” If like me, you’re wondering what that means, the answer lies in the drink’s contents.

Brein Fuel contains a whopping 360 mg of naturally sourced caffeine blend of green coffee bean extract, unroasted coffee beans, and green tea extract. Aside from that, the beverage also has a ton of antioxidants and low-glycemic metabolic fuels.

This packed blend of brain-boosting additives aims to give a gradual energy boost and enhanced mental performance. A lot of their ingredients definitely are not usually seen in energy drink brands, so Brein Fuel is pretty interesting in that regard.

Join me as I look deeper into these ingredients and see for yourself if Brein Fuel is the beverage you’re waiting for.

Let’s dive in!

Ingredients of Brein Fuel Energy Drink

The ingredients that make Brein Fuel a performance booster and an impactful beverage are the following:

  • Water
  • Hydrolyzed Bovine Collagen
  • MCT Fractionated Coconut Oil Powder
  • Creatine Monohydrate
  • D-Ribose
  • Erythritol
  • Citric Acid
  • Natural Flavors
  • Beet Root powder
  • Ascorbic Acid
  • L-Theanine
  • Green Coffee Bean Extract
  • Caffeine
  • Fruit and Vegetable juice for color
  • Vitamin E
  • Sucralose
  • Green Tea Extract
  • Sodium Benzoate
  • Potassium Sorbate
  • Zinc Citrate

Let’s take a look at some of these ingredients!


BreinFuel, in particular, contains collagen, which is one of the most abundant proteins in the human body found in the bones, muscles, skin, and tendons.

It essentially is used to form the connective tissue and ligaments between the bones and muscles. Collagen acts as a scaffold that provides strength and structure.

With the right amount of collagen, you can say goodbye to those pesky joint and knee pains!


This unique ingredient present in BreinFuel is known for its wide array of benefits; however, most of these “benefits” have not been appropriately proven and are essentially just speculations. Some researchers claim that MCT oil aids in weight loss, regulate blood sugar levels, and even helps with neural diseases like Alzheimer’s and autism!.

Additionally, due to its simple structure, it does not take much time for the body to digest it. Like with glucose, it can be used directly by your body cells to produce energy, which might help give that boost you desperately crave.


Beetroot has been gaining popularity for being a ‘super-food,’ and it is no wonder that the makers of BreinFuel decided to use it as one of the ingredients. Its benefits have been widely researched, and beetroot does genuinely work wonders.

It helps reduce blood pressure and, with it, improves blood circulation and heart health. It has been shown to improve the digestion of large macromolecules and minimize the possibility of diabetes.

It even has antioxidant properties, and some of its compounds, like betalains, in particular, have displayed the ability to disrupt the mutation of cancerous cells.

Nutritional Facts of Brein Fuel Energy Drink

The nutritional facts are crucial to know before consuming any product, especially when you have health concerns or a particular medical condition.

Without further ado, here are the nutrition facts of Brein Fuel!

Caffeine Content in Brein Fuel Energy Drink

Each bottle of Brein Fuel energy drink contains a whopping 360 mg!

Caffeine has numerous benefits, including improving your performance and the speedier response you can expect if you intake sufficient caffeine during the day.

But caffeine can also cause some side effects when you take it excessively, which is why the FDA recommends that healthy adults keep their intake to a maximum of 400mg per day.

Unfortunately, Brein Fuel’s caffeine content is very close to this daily limit. While it does not technically reach 400mg, the high content makes it unsuitable for those who have low caffeine tolerance.

Remember, other products like chocolates and soda also contain caffeine, so if you take a bottle of Brein Fuel and then consume other caffeinated products, you can quickly overtake the recommended limit.

If you’re a beginner at energy drinks, better start with brands with lower caffeine. If you’re a veteran, I still recommend trying just half a serving first.

Consuming more than the recommended limit can cause the following side effects:

  • Dehydration
  • Jitters
  • Insomnia
  • Palpitation
  • Anxiety
  • Dizziness

Calories In Brein Fuel Energy Drink

There are 90 calories present in each bottle of Brein Fuel.

Calories are an essential source of energy, but consuming more calories than you can burn off in a day can have adverse effects.

90 calories aren’t all that much, in my opinion, especially if you regularly work out anyway. But just in comparison, a lot of other energy drink brands have chosen to sell calorie-free energy drinks to cater to more diets and lifestyles.

Drinking Brein Fuel energy drinks comes with a lot of calories. Energy drinks can sabotage your weight loss efforts if you’re trying to reduce them. Take note of how many calories you consume if you choose to use this energy drink.

According to the NHS, the recommended daily caloric intake for men and women is 2,500 calories and 2,000 calories, respectively. 

It would be best to consider your age, metabolic rate, and level of physical activity when calculating your daily calorie requirement.

If you keep track of how many calories you consume each day, you can maximize your energy levels without gaining too much weight.

Vitamin Content in Brein Fuel Energy Drink

Brein Fuel Energy Drink contains Vitamin C and Vitamin E.

Blood vessels, cartilage, muscles, and collagen in bones are formed by vitamin C (ascorbic acid), a nutrient your body needs to function and heal itself.

Free radicals are the molecules produced when your body breaks down food or is exposed to x-rays or solar radiation, and they can cause damage to your cells. Vitamin C helps your cells resist these damage-causing molecules. 

Free radicals may cause heart disease, cancer, and other illnesses. Vitamin C is also necessary for iron absorption and storage in the body.

On the other hand, Vitamin E is a nutrient essential to your vision, reproduction, blood vessel health, brain function, and skin health. It also has antioxidant properties!

Is There Sugar in Brein Fuel Energy Drink?

Brein Fuel contains 4g of sugar per bottle.

However, the sugar they used is D-Ribose, a low-glycemic sugar that our bodies naturally produce. This type of sugar is particularly beneficial in your body’s energy storage and can relieve symptoms of certain diseases and improve cardiovascular health!

Powdered sugar in a spoon

According to the American Heart Association (AHA), men should consume no more than 36 grams of sugar per day, and women should consume no more than 24 grams.

Sugar taken in over the recommended amount can have adverse side effects, including:

  • Tooth decay
  • Obesity
  • High blood pressure
  • Fatty liver disease
  • Chronic inflammation
  • Weight gain
  • Increased risk of type 2 diabetes

Does Brein Fuel Also Contain Artificial Sweeteners?

Yes, Brein Fuel uses an artificial sugar called sucralose, and it works wonders.

Sweeteners such as sucralose contain 600 times the sugar’s sweetness and are either low in calories or have none at all.

Artificial sweeteners are made by converting sugar into synthetic sweeteners in a laboratory, so they taste like sugar.

However, this sugar does not affect blood sugar or insulin levels, unlike regular sugar. Due to its sugar-free nature, it is popular among diabetics and others who avoid sugar.

Sweeteners are FDA-approved and safe for consumption!

Is Brein Fuel Energy Drink Bad for You?

Drinking Brein Fuel energy drinks in excess may be harmful to your health.

While Brein Fuel is formulated with a lot of beneficial ingredients, its caffeine content is a massive red flag for me. From my personal experience, 50-100 mg is quite enough to give me a solid energy boost without the jitters, so any more than that is just overkill.

Regularly consuming highly-caffeinated drinks can result in caffeine overdose or dependence. A little goes a long way, and you don’t really want to jeopardize your health just for some caffeine boost, right?

How Many Bottles of Brein Fuel Energy Drinks Can You Drink in a Day?

So if you do take a liking to Brein Fuel, I think 1/2 bottle to 1 bottle per day would serve you best.

A half bottle is equivalent to 180mg, which is already quite substantial for me. If you’re used to drinking low-caffeine drinks, then I think a half bottle is a good idea.

I only recommend drinking 1 bottle if you’re used to drinking highly-caffeinated drinks without experiencing adverse side effects and in good physical condition.

And don’t even think about going beyond 1 bottle! That’s just too much.

There are other ways to stay energized throughout the day besides drinking energy drinks like Brein Fuel, such as

  • Staying hydrated
  • Regularly exercising
  • Getting vitamin D from sunlight
  • Eight hours of sleep per day

Flavors of Brein Fuel Energy Drink:

The Brein Fuel energy drinks are available in four different flavors.

Other Notable Mentions


Brein Fuel has a plethora of ingredients that are designed for a gradual energy boost and improved focus. This blend combines coffee beans and green tea for a naturally-derived caffeine power-up.

It also makes use of low glycemic sugar, antioxidants, MCT, beetroot, and other nutrients to enhance the brain’s response to caffeine.

The one catch to Brein Fuel is its exorbitant 360mg of caffeine. Personally, that’s too high for me, and I am weary of the adverse side effects that much caffeine can cause, especially if you have a low tolerance.

I think Brein Fuel really put a lot of thought into their product, but at the end of the day, I won’t recommend it for daily consumption or for everyone.
