Love these bars. Taste great, and the nutritionals are spot on. Very welcome relief from most of the competition.
A protein bar that’s actually a protein bar – not a carb, sugar or fat bar.
While most protein bars might contain more carbs or sugar than protein, the Form Protein Bar is high in protein while being low in carbs and sugar.
Crafted with our signature approach to quality nutrition, each bar provides a generous 15g protein with no compromise on taste, texture or macros. Ideal as a quick pick-me-up between meals, a smart on-the-go option, or as a post-workout refuel when you don’t have time to shake things up.
With a delicious chocolate casing, indulgent bite and excellent macros, the Form Protein Bar makes it effortless to fuel well, recover well and feel your best, all in one convenient bar.
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.

Yummy and healthy! Not only with protein, but high in fibre too
Thank you for your review and the 5 stars Kerstin 🙂 Happy you love the bars and the fibre content too!
Great protein bars compared to what’s available on the market!
Thank you for the lovely feedback Lewis! Happy to hear you love our bars 🙂
It is a protein bar, so it’s not going to hit exactly the same as a straight-up chocolate bar, but this is genuinely one of the best options that I’ve tried. There’s a nice mixture of textures, with the caramel and the crunchy bits, and the flavour is good and doesn’t taste overly artificial. It’s good value for money with the subscription as well.
I’ve tried the salted caramel and am looking forward to trying the choc PB.
Wow what a great, detailed review Belle – Thank you for that! We’re happy you love the bars and hope the Choc Peanut bar will hit the mark for you as well 🙂 Thank you!
Taste is great and they are very satiating but the texture is not too dense and chewy like traditional bars. Will buy again!
Thank you for leaving us feedback Pablo, – we’re happy you like our protein bars as much as we do!
I’ve had a week of the chocolate peanut bars so far and I like them. They are a good texture, not overly dry like some other brands so good to chew and the flavour is nice. Good to know they aren’t packed full of sugar and carbs as well.
So glad you’re enjoying the bars Anna! Texture is a big one for us, so this means a lot. Thank you so much for the lovely feedback!
