High Fibre Protein Bars: What Makes Fibre Boost Different (2026)
, 3 min reading time
Most protein bars barely mention fibre. Here's what actually makes a bar "high fibre," how Fibre Boost's cold-pressed formula compares, and what to check before you buy one.
Scan the nutrition panel on most protein bars and fibre is an afterthought — a gram or two, if it's listed at all. That's despite most Australians falling well short of the recommended 25 to 30 grams of fibre a day. Fibre Boost built an entire range around closing that gap without giving up the protein hit people buy a bar for in the first place. Here's what actually separates a genuinely high-fibre protein bar from one that just says it on the label.
What Counts as "High Fibre" for a Protein Bar
Under Australian food standards, a product can carry a "good source of fibre" claim at 4g per serve, and a "high fibre" claim at 7g or more per serve. Most protein bars sit somewhere below that, since fibre isn't usually the ingredient doing the heavy lifting — protein and sweeteners are. A bar with 20g or more of fibre per serve, like the bars in the Fibre Boost Protein Bars range, is in a different category entirely.
How Fibre Boost Bars Are Actually Formulated
Fibre Boost bars are cold pressed rather than baked — the ingredients are compressed, not cooked, which is part of what allows a much higher fibre load without drying the bar out (our cold pressed vs baked guide covers why that process matters). As an example, the Choc Hazelnut bar's official nutrition panel lists 24.7g of dietary fibre and 20.6g of protein per 60g bar, at 162 calories. The fibre itself is a soluble prebiotic fibre sourced from corn — different from the insoluble wheat bran or chicory root fibre used in some other "high fibre" snack products.
Worth knowing: the bars are built on whey protein isolate and milk protein isolate, and the official ingredient panel lists them as containing milk. If you're after a dairy-free or vegan high-fibre bar, this isn't it — despite some retail listings showing a "vegan" tag, the manufacturer's own packaging says otherwise. Our full nutrition and ingredients guide breaks this down flavour by flavour.

Why Most Protein Bars Skip the Fibre
Baked bars typically rely on syrups, rice bulking agents or sugar alcohols to hold their shape and sweetness, none of which contribute meaningful fibre. Adding a genuine dose of soluble fibre to a baked bar tends to dry it out or make it crumbly, which is part of why cold pressing — a process built around compression rather than heat — suits a high-fibre formulation better.
Who Actually Benefits from a High-Fibre Bar
- People on low-carb or keto plans, where cutting carbohydrates often cuts fibre intake at the same time. Browse our keto snacks Australia collection for more options built around that gap.
- Anyone who trains regularly and wants the protein without the sugar spike some recovery bars carry.
- Most Australians, generally — fibre is one of the most commonly under-consumed nutrients in a typical diet, and a single bar can meaningfully close that gap.
What to Check Before You Buy a "High Fibre" Bar
Not all fibre sources behave the same way. A few things worth checking on any high-fibre bar's label, Fibre Boost included:
- Soluble vs insoluble fibre — soluble fibre (like the corn-derived fibre in Fibre Boost bars) tends to be gentler on digestion than insoluble sources for most people.
- How your body handles a sudden increase — if you're not used to 20g+ of fibre in one sitting, start with half a bar. A sudden jump in fibre intake can cause bloating regardless of the source.
- What else is in the ingredient list — fibre content alone doesn't tell you about allergens, added sugars or protein quality.
