I might be biased but I love these protein bars and guarantee you will too!

frequently asked questions
How many calories per bar?
What makes Form Protein Bar different from other protein bars?
Form Protein Bar is designed as a high-protein, high-fibre, low-sugar bar with 15g protein and just 1g sugar per bar. Many others still lean closer to confectionery in terms of carbs and sugar – check your labels closely!
When is the best time to eat a Form Protein Bar?
Whenever it works for you:
- Post-workout – 15g protein is a great amount for a post-training snack
- Between meals – the combination of protein and fibre helps keep you satisfied.
- On-the-go – travel, office, handbag, gym-bag, anywhere you’d otherwise grab a less healthy snack.
Is Form Protein Bar suitable if I’m trying to manage my weight?
Form Protein Bar isn’t a weight-loss product, but its high protein, high fibre and low sugar profile makes it a smarter choice than many standard snack bars when you’re watching calories or trying to stay fuller for longer:
- Protein and fibre both support satiety (feeling full)
- Low sugar helps avoid large swings in blood sugar that can drive cravings.
For weight management, think of it as a better snack option within an overall balanced diet and active lifestyle.
Is it ultra-processed and should I be worried about that?
There’s increasing discussion around ultra-processed foods (UPFs) and health. Most foods, including protein powders and protein bars involve some level of processing.
What matters in practice more is nutritional profile – high protein, high fibre, low sugar vs high sugar and saturated fat.
Form Protein Bar is created as a nutritionally healthy snack: high protein, high fibre, low sugar. If you’re interested in learning more about UPFs we’ve written about it here.
15g plant-based protein for muscle growth and repair
While many protein bars top out at around 10g per bar, the Form Protein Bar contains a category leading 15g from pea and pumpkin seed proteins making it ideal post workout or anytime you need a healthy, filling snack.
Chicory root is naturally rich in inulin, a prebiotic fibre that supports a healthy gut and helps you feel fuller for longer. This helps feeds beneficial gut bacteria, encouraging the production of short-chain fatty acids that support digestion and overall wellbeing.1 It also slows carbohydrate absorption, helping maintain more stable energy without the spikes linked to high-sugar snacks.

High in fibre with 12g fibre per bar from chicory root
Chicory root is naturally rich in inulin, a prebiotic fibre that supports a healthy gut and helps you feel fuller for longer. This helps feeds beneficial gut bacteria, encouraging the production of short-chain fatty acids that support digestion and overall wellbeing.1 It also slows carbohydrate absorption, helping maintain more stable energy without the spikes linked to high-sugar snacks.
With UK adults recommended to consume 30 g of fibre a day, chicory‑root fibre helps make each bar a genuinely functional, high‑fibre choice.2
Low in sugar and low in carbohydrates
If you’re a regular reader of protein bar labels you know most are more carbs or sugar than protein, especially if they’re made from dates or other fruit bases. The Form Protein bar is just 1g sugar per bar and 7g carbs, meaning it’s a protein bar that really is a protein bar, not a carb or sugar bar.
If you know the average protein bar you know the deal, chalky, chewy, or sweet enough to pass for dessert. The Form Protein Bar hits different. Wrapped in a smooth chocolate casing for real indulgence, it features a luscious caramel layer and the kind of crunch you crave, thanks to crispy protein bites layered throughout.

Form protein bars- the product we have all been waiting for!
After trying so many protein bars that aren’t actually very high in protein and hurt my tummy, when we saw form had released their own version, we were very keen to try and it didn’t disappoint.
They taste as good as they look, vegan and 15g per bar. My only suggestion would be to offer a mix pack of flavors as I imagine it might get samey otherwise.
If you are looking for a vegan bar with no additives and very low sugar, the lowest I have seen so far, then you should definitely go for these bars. As someone who is quite used to vegan flavors, whether in protein products or bars, I found this one very tasty, crunchy, and light.
However, please note that this is a truly vegan product, so the taste will be different from most bars available on the market. I’m happy to see what comes next.
Really like these bars – I bought the chocolate peanut flavour and they satisfy any chocolate cravings whilst also being a great source of protein. Enjoying them in the afternoon with a cup of tea in preparation for a workout.
I bought the Chocolate Peanut bars as I like peanuts and wanted to try lower-sugar protein bars than my usual ones (from the supermarket). I’m disappointed that these don’t contain actual peanuts and the list of ingredients is very long, so not as natural as I was expecting.
However, they were satisfying and surprisingly sweet-tasting considering the very low sugar content.
I found the texture a little mealy but not so much that it put me off. My husband had one and liked it too, but my 20year-old son only ate half a bar then binned it!
Not yet decided whether I will buy another box, as they are very expensive.
Thank you for taking the time to share such thoughtful feedback Hazel! We’re glad to hear you found the bars filling and pleasantly sweet despite the low sugar content, Thank you also for your comments on ingredients, texture and pricing as this kind of insight is incredibly valuable to us.
I really wanted to love these bars but unfortunately I don’t. The chocolate is fine but the caramel isn’t as gooey as I would have hoped and the bottom layer is chalky and crumbly. They do keep me full but I won’t buy them again.
Thank you for taking the time to share your honest feedback Sarah, we’re really sorry to hear the bars weren’t quite right for you. We do appreciate you highlighting what worked and what didn’t.
