Most of us don’t get enough fibre from food alone — general guidance suggests 25–40g a day, and most adults fall well short of it.

That gap gets even harder to close once you’re eating smaller amounts, like in the months after surgery, and a lot of fibre products don’t make it any easier: gritty texture, chalky aftertaste, bulky drinks that are a chore to get through.

There’s an easier way to close that gap without any of that — BN Fibre is a simple, completely invisible way to top up your fibre without changing a single thing about your meal. It’s 100% soluble corn fibre: tasteless, colourless, and completely invisible once it’s in. Stir it into water, a hot drink, a smoothie, or straight into food, and it disappears — no clumping, no gritty texture, nothing to work around, nothing to carry that needs prep.

Because it’s soluble, BN Fibre behaves differently to the fibre you might be picturing — it won’t bulk up your stool the way insoluble fibre can, so it’s a gentler, easier way to stay on top of your fibre without extra bulk or bloating. Dietary fibre contributes to regular bowel motions, as part of a healthy, balanced diet.

Soluble fibres like this one are also fermented by the bacteria that naturally live in your gut, feeding the good bacteria and supporting a healthy gut environment — which is part of why so many people reach for one as part of looking after their gut day to day.

Why people add BN Fibre to their day:
100% soluble corn fibre — convenient, mixes in completely invisible and tasteless.
Works in hot and cold drinks, smoothies, food and cooking.
No clumping, no gritty texture, no added bulk.
No sugar, artificial sweeteners or colours.

Most adults fall short of the recommended daily fibre intake. BN Fibre is one small, easy habit that helps make up the difference — stirred into your morning drink, a soup, or a smoothie, wherever’s easiest for you.

What is fibre?
Fibre is the indigestible part of plant foods — vegetables, fruits, grains, beans and legumes. It passes through the digestive tract largely intact, and dietary fibre contributes to regular bowel motions as part of a healthy diet.

Soluble vs insoluble fibre
Both matter, and most diets benefit from a mix. Soluble fibre dissolves in water and forms a gel-like substance as it moves through your system — natural sources include oats, nuts, seeds, fruit and vegetables. Insoluble fibre doesn’t dissolve — it travels through your digestive system largely unchanged, adding bulk along the way. Whole grains and bran are common sources.

BN Fibre is a soluble corn fibre — smooth, tasteless, and easy to add wherever you need it, without the bulk.

100% Soluble Corn Fibre

Initially, Stir 1 scoop of BN Fibre into at least 30–50ml of your favourite beverage or food — dissolves instantly. Increase in 5g increments, to avoid bloating and discomfort as your body adjusts to more fibre. This is experienced as your gut microbiome improves as fibre will support the growth of healthy gut bacteria.

When mixed in beverages, consume immediately or store covered in the fridge for no more than 24 hours.

  • Do not use it if the seal is broken or missing.
  • If pregnant or nursing, consult your healthcare professional before use.
  • Store tightly closed in a cool, dry place.
Carefully formulated to target your concerns.

No Bloating

BN Fibre does not cause additional bloating with regular use.

Stabilise Glucose Levels

Fibre can help control high blood sugar levels.

Keeps You Regular

Fibre softens and bulks up your stools, making them easier to pass.

Customers praised this corn fibre supplement for being "tasteless" and dissolving easily in beverages, foods, and protein shakes. Reviews highlight its effectiveness for digestive regularity, with many noting it's "gentle not aggressive" and works within days. Some mentioned it requires more stirring than other products and can be "puffy" when mixing. Highly recommended for post-surgery use.

Handy and easy

I so appreciate having a quality Fibre product that I can put into coffee, shakes, meals....basically anything.

Needs a little more stirring to get it to dissolve than the collagen products, but it's not a huge problem.

No aftertaste and a much welcome addition to my routine.

Tasteless and dissolves

It's gluten free, tasteless and dissolves easily. I add one heaped scoop of this fibre and the tasteless protein powder into 600mls of water with one scoop of staminade or powerade. I drink 3of these throughout my day which provides 1800mls water, 60g protein and 20-25g of fibre. The electrolytes help reduce dizziness.
