What is a Brain Energy® soft drink?
A soft drink for thinking, not for racing.
Brain Energy® is our idea of a soft drink: just the right amount of caffeine, from a natural source, and no sugar. A can has 20 mg, less than a third of an espresso and a quarter of a classic energy drink.

Ingredients
What’s inside. And why.
Few ingredients, each with a job: the natural caffeine, the flavour or the signature touch of the recipe.
The natural caffeine
Yerba mate
The leaf people in Argentina, Uruguay and Paraguay have been drinking for centuries. It gives every can its caffeine: 20 mg, less than a cola. And that herbal note you taste when you drink it.
The tradition
Lion’s mane
An edible mushroom (Hericium erinaceus) used for centuries in Chinese and Japanese cooking. We add it as an extract to every can.
The flavour
Fruit
Organic lemon juice and fruit extracts: mango, passion fruit and rhubarb in Focus; blueberry and strawberry in Mood; yuzu, grapefruit and mint in Immunity.
What’s not in it
0 g of sugars
Sweetened with sucralose, no colourings and 10 kcal per 250 ml can. Lightly sparkling.

Amazon reviews
What people who’ve tried it say.
“I bought 2 boxes because a friend recommended it. The taste is smooth and natural, not like other energy drinks that taste more artificial.”
“I tried it at the Volta a la Comunitat Valenciana cycling race and it tastes really natural. After trying it, I went on to buy the pack.”
“I’m a big coffee lover […]. Yerba mate, on the other hand, is the perfect substitute. Without a doubt, one of the drinks of the future.”
“It has a mate base and a fruity touch that give it a good taste.”
