5 of the best protein bars we’ve tried

Published by Finn Hayden

Protein bars are a convenient and often tasty way to get your protein fix. Although these were once reserved for bodybuilders and fitness freaks, now more people than ever are consuming protein bars. Go to virtually any supermarket in the UK and you'll likely find a hefty selection to choose from.

But a bigger selection of protein bars means making a choice is more difficult than ever. For this reason, we wanted to create a list of the very best protein bars you can get in the UK right now (2023). We'll be looking at the cost, the taste, and of course the macronutrients to see which bar gets you the best bang for your buck. Let's get into the list:

FULFIL protein bars (our current number one choice)

If you're a fan of the Boots meal deal then you might recognise these little gems from the snack section - getting them as part of a meal deal is really excellent to be honest. The best thing about these bars, aside from the great nutritional stats, is the taste. My goodness that Chocolate Hazelnut Whip is good.


At the moment (September 2022), the 55g bars (which contain 20g protein each) are on a great deal over on Amazon, with 15 bars for less than £19 - that is cheaper than Aldi protein bars! Check them out on Amazon here -

Lidl protein bars

We've already published an entire guide about the Lidl protein bars, declaring our love for them and our surprise at how great they are. Despite being cheap (cheaper even than Aldi), the nutritional breakdown is really impressive, with each bar packing more than 22g of protein. A 3-pack will cost you less than £3, which is the cheapest protein bar we could find. The only major downsides to the Lidl protein bars is that they're actually quite hard to get your hands on, and you can't order them online. We can't tell you how many times we've gone to Lidl on a mission to buy lots of these, only to find empty shelves!

Aldi protein bars

We don't want to give you the impression that the Aldi protein bars are totally worthless in comparison to the Lidl protein bars - after all, we reviewed the Aldi selection very favorably as well, and the Aldi bars are only slightly more expensive. There is even an argument to be made that the Aldi bars taste slightly better, particularly if you're a fan of quirky flavours like Birthday Cake.

Grenade is by far the biggest protein brand in the UK right now, and one of the biggest in the world too. And it's actually not too hard to see why either - the nutritional breakdown is great, and the taste is probably the best you'll get on the market. However, the main issue we have with these is the price. Explore the range here -

PE Nutrition (Holland & Barrett)

PE Nutrition is a fairly new brand on the scene, but they're owned by Holland & Barrett so they've quickly found a place on the shelves of the popular high-street health shop. Explore the range exclusively on the Holland & Barrett website here -

Final thoughts

Protein bars are awesome, but we'll be the first to admit that they can vary greatly in quality. Hopefully this list has helped you to find a protein bar you can enjoy, let us know in the comments what your favourite protein bar is.
