Protein Flapjacks & High-Protein Oat Bars

Looking for something a little more substantial than a typical protein bar? Supbox brings together protein flapjacks and high-protein oat bars from a growing range of brands, flavours and styles, all available to buy individually.

Pick & Mix Your Protein Flapjacks

Choose individual flapjacks, mix different brands and flavours in the same order, and build your own pick & mix protein snack selection. It's an easy way to try new flavours without committing to a full box or multipack.

Our range regularly changes as we discover new products and brands. From classic oat-based flapjacks to chocolate-covered and flavoured options, you can try different products alongside protein bars, cookies, chips and other snacks from across the Supbox store.

Products are supplied in their original sealed manufacturer packaging. Supbox doesn't manufacture or repackage the protein flapjacks. We bring products from different brands together in one place.

Discover Your Next Protein Snack

Supbox is built around making protein snacking more varied and interesting. Browse our range of protein flapjacks, high-protein flapjacks and protein oat bars, choose the individual flavours you want to try and discover your favourites without buying an entire box.

These are also found in our Snack Box and Full Mystery Box if you would rather we chose what you should try next.
