BrèinFúel Review

breinfuel flavors

It's been a little while since something unique has come across my desk within the energy drink category.  BrèinFúel intrigued me because it is essentially combining several types of sports drinks/supplements into one all-encompassing beverage.


I tried two flavors of BrèinFúel, the Alpha Punch and the Limitless Berry. Both offered a sweet fruity flavor that to my surprise, was also creamy. However, there is no dairy in BrèinFúel. 

I enjoyed both flavors and they were nice to sip over time instead of drinking as fast as possible like other energy beverages. 


This is where BrèinFúel gets really interesting. This beverage has not only some of the highest caffeine levels on the market but also a plethora of other ingredients. 

  • Collagen drinks have become popular recently and BrèinFúel has enough to deliver 6 grams of protein.
  • MCT oil has also become popular and BrèinFúel has you covered there with 5 grams.
  • Its caffeine comes from green tea and coffee beans including a dose of L-theanine to counteract some of the negative properties associated with caffeine. 
  • Beyond that, BrèinFúel also has a high dose of Vitamins C and E, Calcium, Iron, and Zinc topped with a serving of Beetroot Powder. 

BrèinFúel's Effect

I sipped the equivalent of one bottle over the course of an hour and I really enjoyed the lift I experienced. No jitters or rapid heartbeat just sustained alertness and motivation. 

However, because of the high caffeine content of BrèinFúel, some people may want to start with half a bottle at first and be mindful of any other caffeine they have had in order to keep levels within the safe perimeters

Overall, I like how BrèinFúel has combined several supplements into one great-tasting beverage. Just use this powerful drink with some caution.
