Fibre Boost Protein Bar Flavours - Ranked and Reviewed 2026
Fibre Boost bars get serious hype. Does it hold up? We scored the full range on protein, sugar and ingredients. Most win, a few really don't.
26 products ranked. Updated 2026-05-19.
Overview
Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip sets the standard for the entire range. It earns a near-perfect Clean Score of 9.9, backed by a simple ingredient panel with only one listed additive. The bar delivers a very 20.9g protein per serve and keeps sugar low at just 0.4g per 100g. It's a clean and effective bar that ticks all the right boxes. Not every flavour hits the same mark, though. The Banana Split bar is the one we'd skip, as it contains the most sugar in the lineup at 4.1g per 100g and sits at the lower end for protein. For a much leaner profile, stick with the top-ranked Choc Choc Chip or any of the other flavours that keep sugar well below 1g.
The verdict
Fibre Boost's lineup consistent, but the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip is the clear standout. It pulls ahead by packing 20.9g of protein per serve into a very clean bar with only one additive. The sugar is also rock-bottom at just 0.4g per 100g, making it one of the leanest protein bars we've scored from the brand. While the whole range is solid, the fruit-based options see the sugar content climb. The Banana Split flavour hits 4.1g of sugar per 100g, a noticeable jump from the leader. For a cleaner pick, stick with the Choc Choc Chip or Choc Raspberry options. Fibre Boost earns its spot as a go-to for a high-fibre, whey-isolate-based bar, especially if you prioritise minimal sugar and additives.

Editorial deep dive
The entire Fibre Boost range is built on consistent formula. Every single protein bar we scored uses the same base of soluble corn fibre, whey and milk protein isolates, and almonds, sweetened with stevia. This blueprint delivers a tight cluster of nutritional results, with almost every bar landing between 33g and 36g of protein per 100g and keeping sugars low. Our top pick, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, earns a perfect Protein Score of 10.0. It delivers 34.8g of protein per 100g with a tiny 0.4g of sugar per 100g. Its Clean Score of 9.9 is driven by just a single additive on the label, a trait shared by almost the entire lineup. The reality is, the top eight bars are all tied on Protein Score, so your choice between Choc Choc Chip, Banana Lollies, or Birthday Cake comes down to flavour preference, not a meaningful difference in the numbers. What sets these protein bars apart is what they leave out. There are no sugar alcohols like maltitol or erythritol, which are common in other protein bars and can cause gut discomfort for some people. Instead, the combination of corn fibre and stevia provides sweetness and bulk. This makes the Fibre Boost range a reliable choice if you're after a clean ingredient list without compromising on a serious protein hit. Ultimately, picking a Fibre Boost protein bar is one of the easiest decisions in the aisle. The brand doesn't have a hero product and a bunch of duds, it has one very product presented in over twenty different flavours. The protein density is consistently high and the sugar is consistently low across the board. Find the flavour you like the most and you've found your winner.
Brand-by-brand notes
Fibre Boost
Fibre Boost dominates our analysis of raw, cold-pressed protein bars, with all 26 products we've scored coming from their lineup. As the name suggests, the brand focuses on minimal-ingredient bars built around soluble corn fibre, whey and milk proteins, nuts, and natural flavours. You won't find these in the major supermarket chains, so purchasing means heading online to order direct from the brand or through a specialty stockist. The performance across the range is remarkably consistent. The average bar delivers 34.6g of protein per 100g, while keeping sugar to low 1.4g per 100g. Our top pick, the Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip, earns a perfect Protein Score of 10.0 and a Clean Score of 9.9, with 34.8g of protein per 100g and just 0.4g of sugar per 100g. There's barely any gap between their best and worst, showing tight quality control. For shoppers after a genuinely clean, high-protein bar, the entire Fibre Boost range is a safe bet. The Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip is our official winner, but it shares the top spot with seven other flavours, so you can pick based on preference. With simple ingredients and nutritionals, any of their bars are worth the online order if you prioritise clean labels over grabbing something from a supermarket shelf.

A large portion of the range shares this low figure, including the Choc Raspberry, Choc Mint, and Cinnamon Donut flavours. They achieve this by using steviol glycosides, a natural sweetener, instead of sugar or artificial alternatives, making them a top choice for anyone looking to minimise their sugar intake.
- How does ProteinScore rank Fibre Boost protein bars?
- We rank protein bars using our Protein Score, a 0-10 metric calculated from the nutrition label. This score rewards high protein content while penalising high levels of sugar and sodium, giving a balanced view of a protein bar's quality. We also calculate a Clean Score, which assesses the ingredient list for its length, and the presence of additives, artificial colours, and sweeteners. Together, these scores help you see which protein bars are genuinely effective and which are just hiding sugar.
- Are Fibre Boost protein bars made with clean ingredients?
- Yes, based on their labels, the Fibre Boost range scores exceptionally well for ingredient quality. The top-rated Fibre Boost Raw, Cold Pressed, Flavoured Protein Bar Choc Choc Chip earns a Clean Score of 9.9. This is driven by a short, recognisable ingredient list featuring prebiotic fibre, milk proteins, almonds, and cocoa. The brand avoids artificial sweeteners, colours, and preservatives, opting for natural flavours and stevia, making them one of the cleanest protein bar options we've analysed.
- Are Fibre Boost protein bars gluten-free?
- Based on the ingredient lists we analysed, the primary components like whey protein, nuts, and prebiotic corn fibre are not typically sources of gluten. However, the packaging does not make an explicit "gluten-free" claim. For anyone with coeliac disease or a serious gluten intolerance, the risk of cross-contamination during manufacturing is always a possibility unless certified. We'd recommend checking the product packaging for the most up-to-date allergen statements and certifications before purchasing.
