Brein Fuel contains 360 mg amount of caffeine content per bottle.

The average amount sufficient for a person to feel fully energized is 100-200 mg. By seeing the amount of caffeine in this energy drink, you may be worried about if Brein Fuel is good for your health or not or if this energy drink will have harmful effects on your health.

The answer is if you are caffeine sensitive or can not take caffeine more than your daily limit, then you should think twice before taking this energy drink.

The FDA‘s recommended daily value of caffeine content for a healthy person is 400 mg. But remember that we all have different caffeine tolerance, so 360 mg may be quite substantial.

Coffee Beans

The caffeine content in Brein Fuel is already above average, so in that case, I’ll recommend that you take only half a bottle of Brein Fuel in a day.

This is derived from coffee beans without being roasted. They are often endorsed for their potential as weight loss aid. 50 mg of Brein Fuel’s overall caffeine content comes from green coffee beans.


D-Ribose is a crucial sugar molecule. It helps improve the heart function of people with heart diseases, exercise performance, and muscle function.


Creatine is known for increasing muscle mass; however, some studies demonstrate that it reduces mental fatigue and improves brain functions.
