ESN Flexpresso

Good morning, is it going to be a coffee or protein shake? Deciding is a thing of the past! We're taking both and presenting our Flexpresso. We combine the best of both drinks: the full protein power of a protein shake and the wake-up effect of coffee. The result: an incredibly creamy and delicious protein coffee!

Let's take a closer look: As befits a protein shake, our protein coffee also contains a good portion of protein, up to 22 g per serving to be precise! 1 Quick reminder: Proteins help your body build and maintain muscle, for example when you are on a diet.3 Speaking of diets: Proteins also help you feel fuller for longer!

And coffee? We have optimized our protein coffee with real coffee to get you through the day with full power and motivation. Everyone should be aware of the wake-up effect of coffee, and probably also the undesirable side effects of too high a caffeine dose. But you don't need to worry about that with our Flexpresso, because, depending on the variety, one serving can contain 80 mg of caffeine, depending on the variety.1
Good to know: You can also enjoy our Flexpresso decaf, i.e. without any caffeine. So if you are looking for a protein powder with a coffee flavor, our Flexpresso is perfect for you!


Make your own protein coffee? Sure, that's possible too. But finding the ideal products and the perfect ratio can be quite annoying. It's easier with our protein coffee Flexpresso: All you have to do is mix the powder with water or milk and enjoy.

Speaking of enjoyment:For irresistible taste and more variety, we have refined our Flexpresso with different flavors. Look forward to caramel, chocolate and more! And the best part? You don't have to worry about unnecessary sugar, because in comparison to conventional products, we do not add any sugar to our coffee protein shake.2

Pro tip: If you fancy a refreshing pick-me-up, try our high-protein coffee with ice cubes or with warm milk.
