If you have spent any time comparing protein bars, you have probably noticed that fibre almost never gets top billing. Fibre Boost Protein Bars flip that script. Each bar is cold pressed rather than baked, built around a genuine dose of soluble prebiotic fibre and whey protein isolate, and sweetened with steviol glycosides instead of sugar alcohols. The result is a soft, chewy bar delivering close to 22 grams of protein and up to 27 grams of fibre, all for under 150 calories.
At Wallaby Wellness we stock the full Fibre Boost Protein Bars range, from single bars to value multipacks, so you can find a favourite without committing to a full box straight away. If you are after a genuine high fibre protein bar that does not compromise on taste, this range is worth a closer look. Not sure where to start? Our complete guide to Fibre Boost bars breaks down the full nutrition profile, flavour notes and how the range compares to other bars on the market.
Why Cold Pressed Matters
Most protein bars on supermarket shelves are baked, which can reduce the nutritional quality of the ingredients and often leaves a dry, chalky texture behind. Cold pressing skips that heat step entirely. Ingredients are compressed rather than cooked, which helps preserve nutrient quality and gives the bars their trademark soft, nougat like bite.
This is also part of why the bars sit well with people who find other high protein snacks heavy or hard to digest. Combined with a short, recognisable ingredient list, cold pressing is a big part of what sets this cold pressed protein bar range apart from typical convenience store bars. For a full breakdown of how cold pressing compares to baking, see our cold pressed protein bar guide.
What Is Actually in Each Bar
A standard 60g bar contains approximately:
- 21 to 22 grams of protein, from whey protein isolate and milk protein isolate
- 25 to 27 grams of soluble prebiotic fibre
- Less than 0.5 grams of carbohydrates
- Under 150 calories
- No added sugar, sweetened instead with steviol glycosides
This combination is one reason the bars are commonly used by people following low carb and ketogenic eating patterns, where fibre intake is often the first thing to drop. For the full ingredient list and allergen information, see our nutrition and ingredients guide. Curious what actually counts as "high fibre"?

Our Fibre Boost protein bar variety packs bundle 12 bars across four flavours, such as the Choc Feast and Most-Loved combos.
Who Fibre Boost Bars Suit
People managing carb intake. Keto and low carb diets often cause a drop in fibre, and these bars help close that gap without adding meaningful carbs. Browse our keto snacks Australia collection for more options.
Gym goers and active people. With over 20 grams of protein per bar, they work well before or after training, and the fibre content may help keep hunger at bay longer than a standard bar.
Anyone short on daily fibre. Most Australians fall well below the recommended 25 to 30 grams of fibre per day. One bar makes a genuine difference, and the soluble prebiotic fibre is commonly used to support digestive comfort as part of a varied diet.
What to Consider Before You Buy
Check the total carbohydrate and sugar content, whether the sweetener suits your preferences, and how the fibre source is described, since not all fibre bars use the same type. It is also worth comparing this range against our broader protein bars Australia collection, or exploring our gut health supplements if digestion is your main focus. Our Best Protein Bars Australia guide runs through how different brands stack up if you want a broader comparison before you buy, or see how the range compares directly in our Fibre Boost vs Blue Dinosaur vs True Protein comparison.

Frequently Asked Questions
Are Fibre Boost Protein Bars vegan or dairy-free?
No. The bars are made with whey protein isolate and milk protein isolate, and the official packaging lists them as containing milk. They are not suitable for vegans or anyone avoiding dairy.
Are Fibre Boost Protein Bars gluten free?
Gluten is listed as "not detected" on the official nutrition panel. If you have coeliac disease, check the current packaging and consult your own dietary guidelines rather than relying on this alone.
How many calories are in a Fibre Boost Protein Bar?
Most flavours sit under 150 to 165 calories per 60g bar, depending on the flavour. See our full nutrition guide for a flavour-by-flavour breakdown.
Are Fibre Boost Protein Bars keto-friendly?
Yes. Most flavours contain well under 1 gram of carbohydrate per bar, which fits comfortably into low carb and ketogenic eating patterns.
How many Fibre Boost bars can I eat in a day?
One to two bars a day as part of a balanced diet is a reasonable guide. If you are new to a high fibre intake, start with half a bar, since 20g or more of fibre in one sitting can cause bloating if your gut isn't used to it.
Where does the fibre in Fibre Boost bars come from?
A soluble prebiotic fibre sourced from corn. Soluble fibre is generally gentler on digestion than insoluble sources when introduced gradually.
