The Best Protein Bars: The Tastiest And Healthiest Options

They ain’t cheap and can contain more calories and sugar than chocolate bars. Choose wisely with our expert’s guide and top picks


Protein is so much more convenient these days. Where once gym-goers had to tuck into a couple of rotisserie chickens to refuel their muscles after a hefty workout, they can now mix up a protein shake or, more convenient still, tuck into a protein bar.

Protein bars are now widely available, involve zero preparation, and generally taste good enough to seem like a treat as well as a way to help build muscle. However, there are downsides to protein bars, mainly involving the diamond-hard texture of some of them, and you need to be careful not to overindulge because they’re not simply a guilt-free replacement to chocolate. Read on for the full lowdown on what to look for in a protein bar, reviews of all the ones we’ve tried as well a top four.

The Best Protein Bars

We’ve tried a lot of protein bars since we first published this article more than two years ago, and we’ve included our impressions of all of them further down this page (jump to our protein bar reviews). But if you just want the best of the best, here’s our top picks ordered by how much protein each contains.

Myprotein Carb Crusher

Our favourite bar: Carb Crusher Strawberry Cheesecake

These 60g bars contain a solid 21g of protein and a respectable 212 calories, but really excel when it comes to flavour. Myprotein seems to have developed the ability to make what could be disgustingly sweet flavours remarkably pleasant. That’s certainly the case with this strawberry cheesecake bar, which scores high for both the taste and not-too-chewy texture.

The fine details: Our hats aren’t just off here, they’re hovering several feet above our heads, because Myprotein has found space for 11g of fibre in a 60g bar. Lovely to see. Our hats did return slightly closer to Earth when we discovered the 2.7g of sugars, but still, that’s not very much sugar. On the protein front you get 21g and there are 212 calories in each bar. A nice bonus comes in the shape of a whole load of vitamins and minerals – around 100% of your recommended daily allowance of 20 different vitamins and minerals, in fact.

Optimum Nutrition Protein Crisp Bar

Our favourite flavour: Chocolate brownie

Most whey bars try for a fluffy or chewy centre and don’t quite pull it off, making them at best a functional snack you eat for the protein rather than the enjoyment. Optimum Nutrition instead goes for a body of crispy rice puffs on a chocolate base and the result is aces. It’s not the honey-sweet Rice Krispie bar you are probably hoping for, but it’s become our go-to when stomach rumbles strike in the afternoon.

The fine details: There’s a solid 20g dose of protein and just 1.8g of sugar, plus 16g of carbs, which is no bad thing if you’re planning on cycling home from work later. However, there’s a fair whack of saturated fats – 5.3g, about a quarter of your recommended daily limit.

Buy from Optimum Nutrition | £17.99 for ten 65g bars

OnePro Protein Bar

Our favourite bar: Peanut butter and cacao

OnePro has absolutely crushed it in flavour and texture with these vegan bars, which are incredibly satisfying. We thought we’d prefer the raspberry and chocolate flavour of the two available, because peanut butter-flavoured bars are ten a penny and are generally dry and chewy, but this one is so much better than any other we’ve tried that we had to recommend it. The raspberry and chocolate flavour is still top-notch, though.

The fine details: The protein is sourced from pea protein isolate and pea protein crispies, and although the protein content is a little shy of the 20g found in most bars, 17g per 57g bar is still solid. The really impressive stat, however, is the 15g of fibre in a bar, which is half your recommended daily intake. It’s still worth mixing up your fibre sources to really give the gut what it craves, but still – half!

Buy from OnePro | £29.99 for 12 57g bars

KIND Protein Bar

Our Favourite Bar: Double Dark Choc Nut

They’re not as high in protein as others on this list, but KIND bars are a genuine treat, full of nuts and dark chocolate This particular bar is made from peanuts, almonds and dark chocolate, so obviously it is very nice. We challenge anyone to make a bar that tastes bad using those three primary ingredients.

The fine details: The protein levels are just 12g per 50g bar, although the fibre count is high at 4.9g. They’re also pretty high in fat at 17g per bar, even if most of that is the “healthy” unsaturated kind. Essentially they lean towards the treat category, with the extra protein content being a bonus.

Buy from KIND | £18 for 12 50g bars

Veloforte Protein Bar

Our favourite bar: Forza

The Forza is hands down the best-tasting protein bar we’ve come across, which means we’re prepared to overlook its downsides, like the high price and relatively low protein content at 12g per bar. This all-natural bar contains a winning blend of apricots, almonds and fennel, and if the word fennel puts you off, try the mix of hazelnuts, coffee and cocoa in Veloforte’s Mocha bar instead.

The fine details: The Forza bar contains three times more carbs than protein with 38.3g of the former (and 27.3g of sugar), making it a better pick for endurance athletes seeking to refuel after a long training session than weightlifters looking for a pure protein punch. It also contains 7.4g of fibre.

Buy from Veloforte | £37.99 for 15 70g bars

33Fuel Eroica Protein Bar

Our favourite bar: Eroica

This is an excellent all-round protein bar, especially for endurance athletes or anyone not especially worried about their carb and sugar intake. It’s one of the only bars that comes close to being as delicious as Veloforte’s Forza bar, since it’s also made from natural ingredients like nuts and candied peels, and it contains more protein at 20g per double-bar pack. However, it’s expensive – those all-natural bars go easier on your stomach than they do on your wallet.

The fine details: The substantial 100g pack contains an awful lot of stuff besides that 20g of protein, and some will be alarmed at the 38g of sugar and 409 calories per pack. It’s high in carbs too, at 43g per pack, and there’s 17g of fat (of which 1.47g is saturates). This is very much a bar for fuelling high-energy pursuits, but it tastes so good you’ll gladly put the work in to justify it.

Protein Bars Buyer’s Guide

Before you start grabbing fistfuls of bars it’s important to know what you should be looking for. The headline is obviously how much protein they contain, but as with all processed food you have to be careful to avoid hidden nutritional nasties. To help determine what you need to check, we enlisted Kurtis Frank from nutrition and supplement encyclopaedia

What should people look for when choosing a protein bar?

“The main factors for choosing a protein bar would be taste, macronutrient composition – how many carbs, proteins and fats there are – and price,” says Frank.

Most protein bars will deliver somewhere between 15g and 25g of protein. Beyond that, you want to look at how much protein you are getting per calorie.

“For macronutrient composition, most bars are either just under 200 calories while giving 15g of protein or are around 250 calories for 25g of protein,” says Frank.

“Both these options are good for overall health and performance since, at the end of the day, they should only be making up a small percentage of your total calories.”

Also make sure you are actually buying a protein bar, not a general energy bar that’s aimed at endurance activities where loads of carbs are required.

“There are quite a few performance bars out there, such as Clif bars, that are meant for snacks during athletics such as biking or hiking,” says Frank.

“They're pretty much all carbs so they don’t work as a protein bar to eat at work or between meals.”

The price of protein bars can vary hugely, and there will be monstrously bad ones at the cheaper end of things. However, if you can find a cheap bar you like, it will obviously help you save money and there are bargains available, especially if you shop online.

“When it comes to price, a premium protein bar can easily be one of the most expensive things in your diet on a per-calorie basis,” says Frank.

“They aren’t cheap, but the cheap ones also tend to taste worse and be made with poorer ingredients so it ultimately ends up being a balancing act based on your preferences and how much you are willing to spend. It is always worth it to at least try the cheaper bars since they might taste good to you and end up saving you money.

“Aim to get a decent amount of protein per calorie and don’t spend too much money unless you need to. If you’ve found a brand you really like then consider buying in bulk online as you can save a lot that way.”

What difference does the type of protein make?

Protein brands will offer many varieties in their bars, and the terms used can be pretty confusing for the layman. Luckily, it shouldn’t matter too much which protein is in your bar.

“The different types of protein matter much less in a protein bar than they do in shakes,” says Frank, “since the rate of absorption for proteins are inherently slowed when put into a solid form and paired with dietary fats and fibres.

“The types of protein with higher biological values [the percentage of the protein that is absorbed by your body] are still technically better but ultimately they're all close enough that debating about milk protein concentrate versus whey isolate is irrelevant.”

A couple of things you should look out on the label is whether there is a high amount of gelatine or soy concentrate, says Frank.

“The only real ways that the protein type is relevant is if there is a high gelatine content, which provides amino acids and appears as protein on a nutritional label but is not a nourishing protein type, or if you're getting 30g of soy concentrate, since in high doses there could be a mild oestrogenic effect [ie it will raise your levels of oestrogen, the female sex hormone] and 30g of the protein is a pretty high dose. Keep in mind soy lecithin is not soy protein and is totally fine in a protein bar.”

Should you be wary of calories and sugar in protein bars?

It’s easy to view your protein bar as a healthy snack, especially as you’ll regularly eat it before or after a gym visit and won’t be so concerned about keeping tabs on your food. However, they can contain more calories and sugar than you might expect, as we found out in our taste test.

“You definitely should be worried about calories and sugars in protein bars,” says Frank, “just as much as you would with candy bars. Just because it can be seen as healthy doesn't make its consumption a free pass to be omitted from your dietary logs or calorie counts.”

On the other hand, you can also pick up protein bars that contain unexpected health bonuses, especially when it comes to upping your fibre intake.

“It is usually a good idea to get at least 5g of dietary fibre in a protein bar,” says Frank. “It helps it go down better, and a lot of us need help to get a decent amount of fibre in our diets.”

What else should you look out for in a protein bar?

Reading the label on protein bars won’t tell you anything about the texture. The worst of them can be rock-hard and leave you chewing for hours.

“Whether or not it can be used as a brick cannot easily be conveyed through the label,” says Frank. “It will ultimately require some taste testing to find out which ones can break a window when thrown.

“Sugar alcohols like sorbitol and xylitol are more common in the cheaper protein bars that are looking to reduce calories by swapping natural sugars out for these ones. While they can be consumed in moderation and aren't necessarily bad, they can definitely cause gastrointestinal upset in some people. If you're eating a protein bar before exercise, this is the last thing you want.”

Protein Bar Reviews

Armed with this knowledge about what to look for in protein bars, we bravely chomped our way through as many as possible. In some cases, that really did take a lot of bravery, and we feel obliged to warn you about those bars here, as well as highlighting a whole load of other excellent protein bar picks that didn’t quite make the best of the best list above.

Bounty Hi Protein Bar

The M&M bar was a hit. The white chocolate Snickers a miss. The Bounty bar marks a return to form and even has a valuable lesson for the rest of the industry: desiccated coconut hides a multitude of sins. Not that the rest of this bar gets much wrong. The centre is gooey, rather than chewy, there’s a milk chocolate casing, and in a move which will keep traditionalists happy, there are two mini bars in each pack.

The fine details Part of the reason coconut tastes so delicious is that it’s so fatty, so you’re using up a third of your daily recommended allowance of saturated fat if you polish off the pack. Artificial sweeteners aren’t used so sugars are also comparatively high at 8g. With all that going on, it’s impressive that 18g of protein was squeezed into a 207-calorie bar. Like the M&M bar, this is a treat with a protein bonus, rather than a healthy staple. But who doesn’t like a bonus with their treat?

The Protein Works Loaded Legends

Our favourite bar: Choc Birthday Caketastic

These smaller snack bars come in under 200 calories per 50g serving, and while the texture is fairly dry, they are an enjoyably crunchy option compared to the chewy grind of some protein bars. The flavours across the range didn’t knock our socks off, so the Caketastic option gets the nod because it has sprinkles on top.

The fine details: Each 50g birthday cake bar contains 189 calories and 15g of protein, and a solid 6.9g of fibre too. There are 16g of carbs, of which 2.1g are sugars, and 7.1g of fat in each bar.

Buy from The Protein Works | £28.99 for 12 50g bars (currently reduced to £23.19)

Bulk Protein Flapjack

Our favourite bar: Chocolate chip

This beast of a bar is one to use after intense workouts when you need a generous helping of protein, carbs and calories to help your body recover. It’s not going to replace the sheer joy of biting into a real chocolate chip flapjack, but it is a satisfying snack loaded with a lot more protein than you’d get from a standard flapjack.

The fine details: Each 85g bar contains 21g of protein, 32g of carbs and 337 calories. There’s also a pleasing 7.6g of fibre, with oats helping to beef up that number, but watch out for the sugar here – at 12g per bar it’s higher than you’ll find in most other options on this list.

Buy from Bulk | £20.99 for 12 85g bars

BodyHero Bar

Our favourite bar: Chocolate

There’s just one flavour of bar available here, and to be honest it’s not outstanding even if there is a pleasant bitter edge to the chocolate. The texture is crumbly and quite dry too, so it’s one to wash down with a cuppa.

The fine details: While it doesn’t excel on flavour, at least the stats make for impressive reading with this vegan bar. It offers 20g of protein sourced from yellow split peas, and there’s also a huge 13g of chicory fibre in each 65g bar. There’s also just 1.8g of sugar in a bar, and the calorie count is reasonable at 267 calories.

Buy from BodyHero | £28.99 for 12 65g bars

Snickers White Chocolate Protein Bar

You’d sacrifice a little of that great Snickers taste in order to get a healthier version of the bar, wouldn’t you? But would you sacrifice all of it? That’s what you’re doing here, unfortunately. This bar somehow manages to be both bland and sickly, with a stodgy texture. It’s not the good stodgy you get from the real thing, either – it’s the unpleasant chewiness that you only find with protein bars.

The fine details: The Snickers protein bar has more protein, fewer calories, less fat and less sugar than a real Snickers bar, but it’s still a lot less impressive on those fronts than most protein bars, despite the obvious compromises made on flavour. It contains 20g of protein (a standard Snickers has 4.6g), 233 calories, 9.7g of sugar and 9.7g of fat. In short, it’s neither a treat nor a healthy snack.

The Protein Works Ridiculous Vegan Protein Bar

Our favourite bar: Wild Chocolate Peanut

Aside from the somewhat zany packaging, there’s nothing especially ridiculous about this protein bar. But that’s no bad thing – do we really need ridiculous protein bars in our lives? The various flavours contain no surprises – chocolate features heavily across the range – and all are satisfying and tasty, with layers of biscuit, nuts and caramel.

The fine details: There’s 15g of protein in each 47.5g bar, along with a substantial 7.6g of fibre. The carb content is a little higher than other bars at 10g, which is good for refuelling after energetic gym sessions. The calorie count of 197 is low though, and there’s just 0.8g of sugar in each bar, with stevia used to sweeten them.

Buy from The Protein Works | £21.99 for 9 47.5g bars (currently reduced to £13.19)


Our favourite bar: Chocolate Peanut Crunch

All the bars in SiS’s new PROTEIN20 range have opted for a “party on the top, business on the bottom” approach, in that there are fun crunchy nuggets above the layer of slightly stodgy, presumably protein-packed filling. The chocolate peanut crunch is the most flavourful of the range, though for our money it’s still a little too bland to work as a replacement for a chocolate bar.

The fine details: Each 55g bar contains 20g of protein and 216 calories. The sugar count is kept to just 2g, with polyols used to sweeten the bar. These are carbohydrates, but not sugars, so the carb total is higher than in many other bars at 22g, which is no bad thing in our view – after a tough exercise session refuelling with carbs is important.

Buy from Science in Sport | £30 for 12 55g bars (currently reduced to £18)

Grenade Carb Killa

Our favourite bar: Chocolate chip salted caramel

The new chocolate chip salted caramel variety of this popular range is seriously tasty. The chocolate coating is littered with chunky chocolate chips and the smooth caramel layer beneath is delicious, if a tad sickly. We’d pick this over a lot of traditional chocolate bars.

The fine details: The macros differ across the Carb Killa range, but this flavour offers 20g of protein in each 226 calorie bar. There’s 1.4g of sugar, which is par for the protein bar course. The 2.5g of fibre is a disappointingly small amount compared with other flavours such as cookies and cream, which contains 6.6g, and other bars on this list. The sweetness comes from the inclusion of sucralose.

Buy from Grenade | £30.99 for 12 60g bars (currently reduced to £18)

Trek Power

Our favourite bar: Millionaire shortbread

One of three new protein-prioritising snacks from Trek, the Power has the most protein per bar with 15g, versus 9g for the protein flapjacks and 10g for the protein nut bars. In truth, if you pick the Power bars you are trading a more enjoyable snack for extra protein, although the Power bars are no slouches in the taste stakes. Peanut Butter Crunch is suitably nutty, but the Millionaire Shortbread edges it for us thanks to its crumbly texture and caramel flavour. Both bars are vegan, although the packet does warn of traces of milk, with the protein punch coming from soy isolate.

The fine details: While less than 20g of protein in a bar means it won’t be your first choice if you’re trying to rebuild muscle after a weights workout, the balance of 15g of protein and 14.9g of carbs in each bar means it’s a decent enough post-workout recovery option for most of us. At 225-229 calories and 10g of fat per 55g bar, make sure you don’t use it as a daily snack, just an occasional treat.

M&M’s Hi Protein Chocolate Bar

Our favourite bar: Chocolate

As people increasingly turn to protein bars as slightly healthier snacking alternatives to chocolate bars, it’s only natural that traditional chocolate brands are aiming to get in on the action. The M&M’s protein bar is not quite as tasty as the chocolate-centred sweet itself, but it is satisfyingly chocolatey and contains large M&M chunks. The texture was hard to judge because we left these on a counter during a heatwave, so presumably they’re not usually quite so liquified, but there were no signs of any stodginess.

The fine details: There are two flavours of the bars – chocolate and peanut – and both contain 15g of protein, which is a solid enough amount for a 51g bar. The peanut bar is a little higher in calories at 207 compared with the chocolate flavour’s 182. However, the sugar levels are high at 15g per bar, half of your daily recommended maximum and significantly more than you’ll find in most protein bars, which tend to use artificial sweeteners instead. That puts these bars firmly in the occasional treat camp, but they’re still a little healthier than going full chocolate.

Oatein Hype Bar

Our favourite bar: Milk and cookies

After securing investment on BBC’s Dragons’ Den in January 2019, Oatein is straying from its oat-based protein cookie and flapjack beginnings (both delicious FYI) with this protein bar. Compared with the many dry and flavourless bars out there, the seriously sweet Hype Bar is a real treat. Fair warning, though – the milk and cookies flavour is extremely chewy so you might have a sore jaw after working through one. If that sounds a bit much, try the gooey salted caramel bar instead.

The fine details: All three flavours contain fewer than 192 calories and less than 2g sugar, with the sweetener sucralose being utilised. Surprisingly there is an eye-popping 21g of carbs in each bar, and a welcome 4g of fibre. The amount of protein per 60g bar (18g) is lower than many others, but considering the Hype Bars contains fewer calories it’s an expected trade-off. The protein comes from a mix of whey and soy.

Buy from Oatein | £29.99 (currently reduced to £17.99) for 12 60g bars

Bulk Macro Munch

Our favourite bar: Brilliant Birthday Cake

Bulk has, somewhat ambitiously, decided to call these gourmet protein bars, which creates an expectation that any bar is going to struggle to meet. We like that the bar has sprinkles on top, and some kind of jam-style layer that adds to the ersatz cake experience. The texture also delivers, avoiding excessive chewiness. It’s a great protein bar – just don’t call it gourmet.

The fine details: Each 62g bar contains 233g calories and 20g of protein, with the sugar count kept low at 2.9g through the use of isomalt and sucralose sweeteners. The list of ingredients is dismayingly long, although to be fair the sprinkles are a surprisingly large part of that. There’s a nice surprise at the end of the nutritional info though – the 8.7g of fibre in each bar.

Buy from Bulk | £29.88 for 12 62g bars

Misfits Protein Bar

Our favourite bar: Chocolate caramel

The caramel in this vegan bar means that it easily avoids the common protein bar problem of being too dry, and the overall flavour is rich without being too sweet. Taste and texture both get a big tick from us, and the other flavour we tried – chocolate hazelnut – is almost as good, just a bit drier.

The fine details: Misfits knows what’s good about the bar and broadcasts it in huge digits on the front of the packaging. There’s 16g of protein (in the chocolate caramel bar, 15g in other flavours) in each 45g bar, and under 1g of sugar. The amount of protein is a little light compared with some other options, but the calorie count is also low at 186, and the hidden bonus is the massive 8g of fibre each bar also contains.

Buy from Misfits | £18 for 12 45g bars

USN Trust Crunch

Our favourite bar: Fudge brownie

Aside from the enjoyably crunchy bits on the top, these bars are pretty unremarkable. The flavour is fairly bland and the texture is a bit too chewy. In short, it’s your basic protein bar – not unpleasant, not all that exciting.

The fine details: Each bar contains 20g of protein and 213 calories, with sugars kept to 1.6g by the use of maltitol and sucralose sweeteners. There is an impressive 7.2g of fibre in a bar though, which is a stand-out stat in an otherwise bog-standard nutritional breakdown.

Vive Natural Protein Snack Bar

Our favourite bar: Peanut butter

For a vegan bar that boasts of its “natural” bona fides, the texture is disappointingly artificial, much like that of a standard protein bar. Even the whole nuts that are suspended in the fluffy filling lack crunch. That’s not to say that the bar isn’t tasty and satisfying – it is, as anything coated in Belgian dark chocolate will be – it’s just that when the nutritional profile is similar to Kind, Eat Natural or Trek bars, we hope for a less processed flavour and texture. One point of difference that may be attractive for some is that there’s no soy involved, either as a protein or the source of the emulsifier lecithin – the bar relies on pea and rice to be a complete protein source, and its lecithin is sunflower-based.

The fine details: We’re in standard vegan protein bar territory here, with 10g of protein in each flavour, all of which clock in at 215 calories. For the peanut butter bar, there’s 4.7g of saturated fat thanks to the nuts and 11g of sugars, mostly from the chocolate and the dates. To counterbalance those figures there’s 6.8g of fibre.

Barebells Protein Bar

Our favourite bar: Hazelnut & Nougat

They say a picture is worth a thousand words, but Barebells’ design is worth precisely one – “lifestyle”, with a premium 1950s Americana look that’s undeniably alluring. We initially found the flavours a bit of a let-down – that is, until Barebells released the new Hazelnut & Nougat bar, which is very tasty indeed. The texture is spot-on too, with an enjoyable level of chewiness that doesn’t stray into the cardboard-style consistency of some protein bars.

The fine details: It’s another of the new breed of bars with very low sugar, just 1.9g, and with 20g of protein in just 205 calories it’s punching above its weight. There’s also a respectable 4.2g of fibre per 55g bar.

Beachbody Beachbar

Our favourite bar: Chocolate Cherry Almond

You really can’t go wrong with chocolate, cherry and almond. The taste is excellent, and the bar’s texture is spot on too. Crispy and immensely satisfying.

The fine details: At just 35g this is one of the smaller bars we’ve tried and the calorie count is kept low as a result – just 151. Consequently, at 10g per bar the protein content isn’t that high either. But despite packing in plenty of chocolate chips and dried cherries, the amount of sugar is also low at 6g, and the 4g of fibre is music to our ears.

Buy from Beachbody | £39.79 plus P&P for 15 35g bars

Eat Natural Protein Packed

Our favourite bar: Peanuts And Chocolate

Unlike supplement companies who move to protein bars from protein powders, Eat Natural have a snack bar heritage which means its protein offering should be especially tasty. And it is – it tastes like a crunchy cereal bar, with chunks of dark chocolate and coconut. The catch is that you get a lot less protein...

The fine details: Just 10g of protein per 45g bar, a little under what most people like to put away straight after a heavy workout session. As a way to top up your protein intake during the day, however, Eat Natural bars are a better snack than biscuits or cake, but keep an eye on the sugar – each bar contains 8.4g. Finally, the fibre – a decent 3.3g per bar.

The Primal Pantry

Our favourite bar: Cocoa Brownie

Vegans aren’t always well served by protein bar makers, but these bars buck the trend by using hemp protein. Not vegan? You may still want to pick these bars because while making a virtue of being made from “real food” may be groan-inducing, the consistency is real nice. The Mixed Berry flavour has a pleasant tang but Cocoa Brownie edges it by tasting like the real thing.

The fine details: The 15g of protein per bar is an impressive tally given they couldn’t lean on whey protein as an ingredient, but – holy sweet tooth Batman! – sugar clocks in at 20g. To be fair, that’ll be the dates, but still, that’s a lot of sugar.

Maxi Nutrition

Our favourite bar: Maximuscle Oat & Raisin Progain Flapjack

There are a lot of options in the Max Nutrition protein bar range. Many of them fall into the too chewy category, but not this oaty treat. Flapjacks are one of the finest foods available and this protein-filled version does them justice.

The fine details: As you’d expect from a flapjack, the calorie count is high at 305 per bar. The protein tally is a respectable 20g, but there’s also 41.2g of carbs including 7.8g of sugar to consider, so these have to be classed as an energy-providing treat to use before or after your more intense workouts. One big plus is the 6.9g of fibre they pack in. That’s over a fifth of your recommended 30g a day.

Buy from Maxi Nutrition | £22.99 for 12 90g bars (currently reduced to £20)

Nutrition X Pro X

Our favourite bar: White chocolate

Nutrition X has doubled the available flavours in its Pro X range. Where once you were stuck with brownie flavour, you can now choose between that and white chocolate. While the former isn’t going to fool anyone in a blind taste test with a real brownie, the latter does taste like white chocolate with a thin caramel filling and a slight crunch thanks to the soy crisps.

If you’re an Olympian in waiting, it’s also worth mentioning the range is Informed-Sport accredited so you shouldn’t fall foul of testing positive for something on the World Anti-Doping Agency banned substance list. Well, not from eating these bars, at least.

The fine details: At very nearly 20g of protein for 200 calories and just 2.3g of sugars, this ersatz white chocolate bar is undoubtedly healthier than the real thing. However, what really got us excited – and excited really is the right word – is the 5.7g of fibre each bar packs in.
