Protein bars are the snack of choice for anyone leading an active lifestyle, providing an on-the-go alternative to more cumbersome shakes and time-intensive meals. 

With that in mind, here’s our pick of the best.

8 Of The Best Protein Bars For Muscle Recovery 2021 | Men's Fitness UK

MF BEST BUY:
Grenade Carb Killa
£30.99 (box of 12), grenade.com

An obvious choice, perhaps, but the UK’s best-selling protein bar is so for a reason. Loaded with 20g protein and just 1.4g sugar, it’s the best-tasting, least-sickly bar we’ve tested.

The Salted Caramel flavour gets our vote, although there are no less than 11 others to choose from. The only downside is restricting yourself to one a day (but who are we to tell you how to live your life).

MF RECOMMENDED:
PhD Smart Bar plant
£29.99 (box of 12), phd.com

With a chart-topping 23g plant-based protein per bar, look no further than PhD if that’s the only factor you’re interested in.

The texture won’t be to some people’s liking, but those recovery credentials make a bit of perseverance worth your while.

SiS Protein20
£30, scienceinsport.com

Utilising a three-part blend of casein, whey and soy protein, these bars chuck everything at your muscles to kickstart growth.

The texture is pleasantly chewy without being too claggy, and Chocolate and Peanut, or Mint Chocolate, are your flavour choices.

Bulk Vegan Protein Bar
£2.49 (per bar), bulk.com

Some might find these slightly too chalky in texture, and the sizeable 279 calories can’t be ignored, but that shake-matching 21g protein is difficult to beat.

If you find protein powders hard to stomach, or you just need a more convenient post-workout option, give these a go.

Reflex Nutrition R-Bar
£22 (box of 12), reflexnutrition.com

Free from any nasty ingredients and loaded with whey protein from grass-fed cows, on paper these bars are top of the pile.

There’s no getting round the fact that they are quite dense, though, and the Chocolate flavour leaves a bit to be desired.

Optimum Nutrition Whipped Protein Bar
£2.49 (per bar), optimumnutrition.com

These bars continue ON’s high-quality range of protein products.

All-natural types should look elsewhere, but if it’s just a tasty training treat you’re after, these boast 20g of muscle-building protein, a nice crisp texture and a relatively low calorie count (197).

USN Trust Crunch
£25 (box of 12), hollandandbarrett.com

Sweet-toothed gym-goers will enjoy the range of dessert flavours (Raspberry Cheesecake, anyone?), and 20g protein is optimal post-workout fuel.

2.5g sugar is slightly more than others bars in this list, but 213 calories is about par.

One Pro Protein Bar
£2.50 (per bar), onepronutrition.com

As well as 17g protein, these vegan bars pack an impressive 15g fibre (half your RDA) to keep gut health in check.

The texture is spot on – a chocolate layer encasing a crunchy middle – but the Peanut & Cacao flavour is a little on the dry side.
