The Advent Calendar

The Perfect Advent Calendar For Any Fitness Lover

How is it the THIRD year of our Protein Advent Calendar already?! It’s crazy to think that this time 2 years ago we were packing boxes in our front room. Since then, we’ve been stocked in Argos, hit BBC News, gone viral on Facebook & collaborated with frickin’ Gymshark!

If you’ve had one of our calendars before – you know what to expect. If you’re new to the party – you’re in for an early Christmas treat. We’ve also listened to customers & created the world’s first multi-brand Vegan Protein Advent Calendar.

Inside, you get 25 full-size protein-packed treats from the best brands around. Expect protein in every format imaginable, from bars & nut butters to balls & cake bites.

Whether it’s for yourself, or to wow the fitness lover in your life, our iconic Protein Advent Calendars make the ultimate fitness gift.

Merry Fitmas!
