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.

The bars are really good. The dark chocolate has a really nice sweet taste to them that balances well with the salty caramel. The texture isn’t claggy or hard to eat like some other protein bars. They can get a bit sticky in the pack but that’s not a huge issue!
That dark chocolate and salty caramel balance is exactly what we were going for Tess, so this made us very happy to read! The stickiness has been revised for our next batch 🙂 Thank you so much for sharing your thoughts!
I tried both flavours: Chocolate Peanut and Chocolate Salted Caramel, and really enjoyed them. Both are delicious, with a lovely texture and not overly sweet. My favourite is definitely the Chocolate Peanut, but I would happily buy either again. I also love that they are high in fibre, have a good amount of protein, and are low in sugar, which makes them feel like a much smarter snack option. Really pleased with my order!
Thank you so much for trying both flavours and for such a lovely review! So glad the Chocolate Peanut won your heart, and we completely agree it is a great snack choice 🙂
Best vegan protein bars I’ve ever tried. They actually keep me full.
We’re so happy to be your favourite, Kristen! Thank you for sharing, it really means a lot to us!
Delicious bars, chocolate is high quality. I purchased to increase fibre in my diet, and one bar provides two-thirds of my daily target. The protein content is a bonus.
Thank you for sharing your thoughts Palbinder! We’re happy to help you meet your fibre goals and also love to hear you noticed our chocolate quality 🙂 Thank you again!
This must be the best protein bar we’ve tried, and both my husband and I love it! Salted caramel is the favourite (just trying to manage all the peanut butter we’re having anyway so happy to have none in it)! It truly doesn’t taste like a protein bar! We keep ours in the fridge for an extra crunch. Crunchy, reasonably sweet (not too sweet) and NO horrible aftertaste. We’ll be buying more.
The fridge tip sounds soo good Ksenija, we will try that too! So happy you’re loving our Salted Caramel bars – they truly are just soo good and we’re happy you feel the same way! Thank you for the five stars!
