Ask any nutritionist, and they’ll always recommend that you get the majority of your nutritional needs from whole foods rather than pre-packaged snacks or powders. That said, there can be a time and a place for balanced and nutritionally dense ready-to-go foods. Protein bars are one of the most popular ways to get a post-workout protein hit, satisfy a sweet craving or fill a 3pm hunger and energy slump.

But not all protein bars are created equal, and with so many to choose from, it’s important to know what you’re picking up. There’s no escaping the fact that the vast majority of supposedly healthy protein bars are ultra-processed foods (UPFs), packed with sugars, sweeteners, oils and fillers. Given that we know UPFs have been linked to poor health outcomes, it’s not unreasonable to want to reduce the amount we consume – or at least be aware that what we’re buying might not be as nutritious as the packaging suggests. 

So, when it comes to grabbing a quick post-class nibble, which protein bars are worth our money? We asked top nutritionists for their take – and you might be surprised by their response. 

We all know that whole foods such as nuts, seeds, fruits and vegetables trump pre-packaged snacks, but protein bars offer a convenient way to up our protein intake, particularly if we’re working out regularly. Like most wellness-based things, it’s all about balance. 

“Whole foods, including those in protein bars, help reduce inflammation internally, provide sustained energy and deliver essential nutrients,” explains nutritionist GQ Jordan. “While I recommend opting for less-processed bars, enjoying the occasional UPF option is perfectly fine. To make the best choice, look for bars with recognisable ingredients like nuts, seeds and whole grains, and those that keep additives to a minimum.”

Remember, eating something (particularly after a tough workout) is better than eating nothing, so if your options are limited, choose the best one available.

“Maintaining a balanced perspective is key,” advises Jordan. “This approach can help reduce food anxiety and support a healthier relationship with food and eating.” 

IQ Bar Almond Butter Chip

“Protein bars can be a convenient source of protein and energy, but how ‘healthy’ or nutritious they are varies,” explains Jordan. “I lean towards those made with whole, minimally processed ingredients because they offer substantial health benefits compared to other ultra-processed options. And I try to choose protein bars that are low in sugar and preservatives. 

“A favourite of mine is the IQ Bar Almond Butter Chip, which has a nice balance of taste and nutritional benefits.” 

Primal Pantry Protein Bar

“While I generally prefer to steer clear of protein bars (or make my own), I do sometimes use them with clients who struggle to get enough protein,” says registered nutritional therapist Alex Allan. “The brand I recommend is Primal Pantry, as these don’t have all the sweeteners, additives and emulsifiers in them that a lot of the others have.”

Fulfil Chocolate, Peanut & Caramel Bar

“I believe healthy snacking is about including more wholefoods and reaching your five a day,” says specialist registered dietitian Nichola Ludlam-Raine, “but if you’re out and about and need a protein boost, then I personally don’t see anything wrong with having a bar – especially if you have a craving for something sweet. I have protein bars once or twice a week because I enjoy them, but it’s important to keep in mind that they do not beat snacks such as carrots and hummus or yoghurt and berries, for example. My go-to are the Fulfil bars.”

Women’s health coach Nicola Shaw agrees. “My go-to protein bars are either Grenade Bars or Fulfil Bars,” she tells Strong Women. “While both are ultra-processed, that’s not problematic if they’re part of an otherwise balanced, healthy diet (ie having good quality nutrition around 80% of the time).

“Both contain around 20g of protein per 55g bar, so are useful in helping us to hit a decent daily quota,” Shaw says. She believes they’re a better option, from a protein perspective, than regular chocolate that has minimal protein. “And both these bars taste great – there are some really fab flavours.”

Kind Peanut Butter And Dark Chocolate Bar   

It may not be a traditional protein bar as such, but this is personal trainer and women’s menopause expert Kate Rowe-Ham’s bar of choice.

“If you look at the ingredients of a targeted protein bar, they’re full of sweeteners, gelling agents, emulsifiers and more sweeteners,” she says. “While they may have more protein than a Kind bar, they also have so much more other stuff we just don’t need. If you really want to up the nutritional value of your post-workout snack, consider making your own energy balls so you’re always prepared with a nutrient-dense, homemade pick-me-up.”

Pulsin Mint Chocolate & Peanut Bar

“Why wouldn’t you want to eat something that tastes like a chocolate bar but claims to help support muscle growth and macro targets?” asks registered nutritional therapist Becca Meadows. “Unfortunately, most protein bars are overpriced UPF confectionery in very convincing wolf’s clothing. However, I do like Pulsin’s plant-based keto bars. They are very low in sugar, have no nasty artificial sweeteners and none of the grainy protein powder taste some brands can have.”

All Real Cashew Cookie Dough Bar

“As with anything we purchase in a packet, protein bars have their pros and cons,” says gut health expert Nishtha Patel. “They can be beneficial and convenient to carry as a quick snack when in a hurry, and they can also be an additional source of protein for people who don’t always meet their protein goals, alongside added vitamins and minerals.

“Additionally, for those who work out a lot, protein bars can aid muscle recovery as they provide all the amino acids required for muscle and tissue repair after exercising. However, they are expensive and often contain a lot of artificial ingredients, such as flavours, colourings and sweetness.

“I personally don’t eat many, but if I had to, I would go for something like this All Real one.”
