Best vegan protein bars to buy 2024

Clif white chocolate macadamia nut bar

• Available from Muscle Food (£2 per bar), Wiggle (£22.68 for 12)

Best vegan oat bar

• Protein per serving: 9.8g per 68g bar

Our tasters said this sweet and salty bar was noticeably natural, compared to other bars, and could even pass for a homemade flapjack. Ingredients include wholesome rolled oats, oat fibre and a good scattering of macadamia nuts. There are numerous forms of sugar added, so this bar would be best for someone looking to energise for an intense workout. Plant-based protein comes in the form of oats and roasted soy beans. Vitamins B6 and B12 have been added to help with the release of energy, which is a plus.

Available from:
Muscle Food (£2)
Wiggle (£22.68 for 12)

This chewy, chocolatey bar is one of our favourites. There's no faint taste of protein, only smooth nougat and crispy hazelnuts – as well as 20g of plant-based protein. Not to mention, there's no added sugar, although those with a sweet tooth would never guess. Enjoy as an afternoon snack to power yourself up for an evening workout.

Available from:
Ocado (£2.50)
Amazon (£29.99 for 12)

Best vegan protein bar for filling up

• Protein per serving: 12.1g per bar
• Calories per serving: 231 kcals
• Type of protein: peanut flour, pea protein
• Type of sweetener: xylitol
• Carbohydrates per serving: 12.1g (7.6g sugar)
• Fibre per serving: 5.5g

This bar contains protein from peanut and pea sources. The ingredients have been packed together to create quite a heavy little bar studded with chopped peanuts and dark chocolate chips. The texture is fairly chewy, making it a really satisfying snack. It’s not too sweet and is seriously filling – a real hunger killer.

A box of 18 bars costs £32.22, coming out at £1.79 per bar.

Available from:
Pulsin (£32.22 for 18)

Clif peanut butter nut butter bar

• Available from Ocado (£2), Wiggle (£22.80 for 12)

Best protein bar for nut butter lovers

• Protein per serving: 7g per 50g bar
• Calories per serving: 229 kcals
• Type of protein: pea protein, oats
• Type of sweetener: brown rice syrup, date paste, cane syrup, tapioca syrup, cane sugar
• Carbohydrates per serving: 24g (10g sugar)
• Fibre per serving: 2.9g

These bars are smaller than some others, but most definitely mighty. Not only do they pack an energy-boosting punch, they taste truly delicious. We couldn't get enough of the chewy flapjack-style bar and creamy peanut butter filling – it reminded us of eating peanut butter straight from the jar.

Many of our tasters felt this bar was a taste sensation. We should point out there are multiple sugars in these bars, so it might not be wise to eat one every day. However, as an occasional treat they would be great fuel pre- or post- workout.

Available from:
Ocado (£2)
Wiggle (£22.80 for 12)

Bulk double chocolate vegan protein brownie

• Available from Bulk (£2.49 each), Amazon (£20.88 for 12)

Best vegan protein bar as a dessert

• Protein per serving: 15g per bar
• Calories per serving: 227 kcals
• Type of protein: pea protein, hydrolysed wheat protein, soy protein
• Type of sweetener: oat syrup, brown sugar, date syrup
• Carbohydrates per serving: 25g (11g sugar)
• Fibre per serving: 3g

This brownie packs an impressive protein punch into each snack, along with some sugar, which is on the higher side, but definitely a good option as a treat. It has a really fudgy texture, like a perfectly baked brownie, and is dense and slightly chewy, with lovely rich chocolate chips sprinkled on top. There is a very slight bitter aftertaste, but dark chocolate fans will enjoy that. Overall, we found this brownie to be excellent – it’d make for a really satisfying after-dinner dessert.

Available from:
Bulk (£2.49 each)
Amazon (£20.88 for 12)

MyVegan Choc Orange Pea-Nut vegan protein square

• Available from MyVegan (£19.99 for 12)

Best tasting vegan protein bar

• Protein per serving: 12g per bar
• Calories per serving: 233 kcals
• Type of protein: pea protein, peanuts, rice
• Type of sweetener: organic cane sugar, grape juice concentrate, dates
• Carbohydrates per serving: 13g (8.3g sugar)
• Fibre per serving: 6.8g

If you're partial to chocolate orange, you'll get on well with this bar. Orange oil provides the citrus flavouring to great effect – it’s natural and zingy without being overpowering. In terms of texture, the bar is quite solid and dense, like tiffin, and studded throughout with chopped peanuts and generous chunks of chocolate. Overall, very enjoyable and satisfying.

MyVegan (£19.99 for 12)

Trek Power Peanut Butter Crunch vegan protein bar

• Available from Sainsbury's (£1.85), Holland & Barrett (£1.68), Tesco (£1.85), Amazon (£31.20 for 16)

Best vegan protein bar for refuelling after exercise

• Protein per serving: 15.5g per bar
• Calories per serving: 229 kcals

• Type of sweetener: dates, glucose syrup, cane sugar, date syrup, fruit juice concentrate
• Carbohydrates per serving: 14.9g (10.5g sugar)
• Fibre per serving: 6.6g

Providing 15.5g protein in each bar, along with 10.5g sugar and 229 kcals, this would be a great option for refuelling after exercise or during a hike. It does taste sweet but not overly so, and it has a rich, melting peanut butter texture with a smattering of crunchy, crispy pieces for good measure – the effect is more like a traditional cereal bar than some of the others. It’s partly sweetened with fruit juice concentrate from grapes and apples, and that comes through pleasantly in the taste.

These bars RRP at £1.75.

Available from:
Sainsbury's (£1.75)
Holland & Barrett (£1.68)
Tesco (£1.85)
Amazon (£31.20 for 16)

Misfits dark chocolate brownie vegan protein bar

• Available from Misfits (£22 for 12), Amazon (£21.99 for 12)

Best low-sugar, high-fibre vegan protein bar

• Protein per serving: 15g per bar
• Calories per serving: 186 kcals
• Type of protein: pea protein isolate, soya protein nuggets
• Type of sweetener: stevia
• Carbohydrates per serving: 8.6g (1g sugar)
• Fibre per serving: 8g

Triple layered and chocolate coated, this bar packs in the protein and fibre, with less than 1g sugar. It has a very deep, rich cocoa flavour with a smooth chocolate coating and crisp, crunchy protein pieces mixed throughout the filling. A layer of caramel at the top adds a touch of sweetness. The texture is a little crumbly and on the drier side, making it a lighter option if you don’t want to feel too full.

A box of 12 bars is £22, working out at £1.83 each. These bars are also gluten-free.

Available from:
Misfits (£22 for 12)
Amazon (£21.99 for 12)

Protein Works Ridiculous wild chocolate peanut vegan protein bar

• Available from Protein Works (£21.99 for 9), Amazon (£21.99 for 9)

Best all-round vegan protein bar

• Protein per serving: 15g per bar
• Calories per serving: 197 kcals
• Type of protein: soy protein isolate, pea protein
• Type of sweetener: stevia
• Carbohydrates per serving: 10g (0.8g sugar)
• Fibre per serving: 8.1g

This ticked all the boxes. It’s an attractive, multi-layered bar with a seam of caramel running along the top and chunks of crunchy peanuts and crispy soy protein nuggets to add texture. It has a lovely peanut flavour and a smooth coating that tastes like milk chocolate. There was an ever so slightly bitter aftertaste (which is very common with vegan protein bars), but it didn’t detract from an overall enjoyable eat. It’s gluten-free, too.

Available from:
Protein Works (£21.99 for 9)
Amazon (£21.99 for 9)

Veloforte Anytime Energy vegan mocha protein bar

• Available from Veloforte (£29.91 for 12), Amazon (£26.39 for 9)

Best vegan high-protein bar

• Protein per serving: 10.3g per bar
• Calories per serving: 310 kcals
• Type of protein: hazelnuts, pea protein, brown rice protein
• Type of sweetener: dates, cane sugar, brown rice syrup
• Carbohydrates per serving: 37.2g (25.3g sugar)
• Fibre per serving: 4.8g

A truly delicious option, this is like eating a dense, fudgy brownie with a pleasing coffee kick, and it provides a respectable 10g protein from plant sources. It’s naturally sweetened with dates, cane sugar and brown rice syrup, but the sugar content is on the higher side. Overall, this would be a good energy-boosting option to refuel and recover after intense exercise, such as a long cycle, run or hike.

A box of 9 bars is £22.99, working out at £2.55 each. These bars are also gluten-free.

Available from:
Veloforte (£29.91 for 12)
Amazon (£26.39 for 9)

Free Soul vegan chocolate brownie protein bar

• Available from Free Soul (£20 for 12)

Best low-sugar vegan protein option

• Protein per serving: 15g per bar
• Calories per serving: 158 kcals
• Type of protein: soy protein isolate, hydrolysed wheat protein, pea protein isolate
• Type of sweetener: maltitol, maltodextrin, steviol glycosides
• Carbohydrates per serving: 16.6g (0.3g sugar)
• Fibre per serving: 5.6g

A tasty layered bar with a rich texture and an indulgent feel. Covered in a generous layer of chocolate, this has a ripple of caramel at the top, adding a nice touch of sweetness without being sickly. Clocking in at an impressive 0.3g sugar, this is a great option if you want to dodge added sugar – though it’s worth noting that it does contain artificial sweeteners for taste.

A box of 12 bars is £20, working out at £1.66 each.

Available from:
Free Soul (£20 for 12)

Vive natural protein peanut butter snack bar

• Available from Vive (£17 for 12), Amazon (£17.89 for 12)

Best all-natural vegan protein bar

• Protein per serving: 10g per bar
• Calories per serving: 215 kcals
• Type of protein: pea, peanuts, rice
• Type of sweetener: organic cane sugar, grape juice concentrate, dates
• Carbohydrates per serving: 14g (11g sugar)
• Fibre per serving: 6.8g

As self-confessed peanut butter fanatics, we had a very good feeling about this one and it didn’t disappoint. The first thing to note is the lovely smooth coating, made using 74% Belgian dark chocolate, which makes the bar feel like a real treat. The filling is densely packed and very rich – it’s full of chunky peanuts, crispy protein bites, cocoa butter and, of course, smooth peanut butter.

With 11g per serving, it’s higher in sugar than some other offerings, as organic cane sugar is used in place of sweetener, but it’s a good choice if you’d rather avoid sweeteners. Vive have focused on natural ingredients in their bars, and the ingredients list is reassuringly recognisable.

A box of 12 bars costs £17, working out at £1.42 per bar.

Available from:
Vive (£17 for 12)
Amazon (£17.89 for 12)

When should you eat a protein bar?

This depends on whether you're using protein bars to hit a certain fitness goal or just to keep you full. Eating a protein bar one or two hours before a workout can increase your performance and boost energy levels. Just be sure to leave plenty of time to digest, otherwise you may suffer from cramps and stomach issues. Alternatively, eating a protein bar 30-60 minutes after a workout can help you refuel and build muscle. If you find you get hungry between meals, pack a protein bar to go.

How to use protein supplements safely

Dietary supplements such as protein bars should be consumed as part of a healthy, balanced diet and not used as a substitute for whole food.

Nutritionist Kerry Torrens explains, "Protein supplements, such as bars, are highly processed and lack the micronutrients and other beneficial nutrients of whole, natural food. We should all aim to achieve our protein requirements from a well-balanced diet, but for short-term use or in certain circumstances, protein supplementation may be considered."

Although protein bars may have healthier credentials than a chocolate bar, it’s important to remember that they’re a concentrated source of energy and can be high in sugar, carbohydrates and fats. Consider your individual health and fitness goals, your personal dietary requirements and your reason for including protein bars in your diet when deciding which product to buy and how often to eat it.

Look into how to eat a balanced diet and the best protein sources, including options for vegetarians and vegans.

Who could benefit from using a protein supplement?

If you’re getting enough protein from your diet, adding a supplement might not make a noticeable difference to your health. However, those who are either unable to regularly eat enough protein due to decreased appetite or illness, or who have increased protein needs as a result of high-intensity exercise might benefit from taking a supplement.

Kerry explains, "One example, which is probably not an obvious one, is the elderly. This group often has a greater need for protein but a lower appetite. Increasing protein intake in a form that is palatable and suits their lowered appetite may be effective in protecting against muscle loss."

"That said, in this group other aspects, such as kidney health and osteoporosis, need to be considered and monitored – it’s worth checking with a GP that protein supplements are safe and suitable for each individual."

Who shouldn’t take protein supplements?

Children shouldn’t take protein supplements unless directed by a dietitian. The NHS advises that consuming too much protein in the long-term is linked to an increased risk of osteoporosis and may worsen existing kidney problems.

Some people find protein bars difficult to digest – it’s best to include them gradually into your diet and see how you get on. Although allergens should be stated on the label, anyone with allergies should be cautious about using a new supplement, as there is an obvious risk of cross-contamination in factories.

Those who are pregnant, breastfeeding or being treated for existing medical conditions should consult their GP before starting new supplements.

Is it possible to take too much protein?

Yes. The Department of Health advises adults to avoid consuming more than twice the recommended daily intake of protein (55g for men and 45g for women).

Always read the label of any protein supplement carefully, stick to the recommended serving size, and be mindful of other protein sources in your diet. If you’re concerned that you might be consuming too much protein, speak to your GP.

Buyers' advice

How to choose a vegan protein bar

Choosing a suitable protein bar will depend on your personal requirements and goals. For example, if you’re looking to gain weight or build muscle, you might want to consider a ‘mass-gainer’ product that is higher in calories and carbohydrates.

Look for a product to fit your dietary requirements and double-check allergen labelling on the packet.

When choosing a protein bar, make sure that you buy from a reputable company, ideally based in Europe, as those outside of Europe may not pass the same safety standards. If you’re in any doubt about the safety of a product, speak to your pharmacist or GP.
