Most fibre powders fail before the glass.
We set out to make a fibre drink that is entirely soluble, easy to use, and part of a routine you will love, not hate. This is what that actually took.
What the test batches taught us.
Every labelled sample in the photo above is a stage the formula went through. Three problems had to be solved before flavour even mattered.
LimepH 2.4
BerriespH 3.5
OrangepH 3.7
WaterpH 7 · neutralBalancing the blend.
Fibre, electrolytes and flavour all pull the pH and acidity of a drink in different directions. We balanced the blend so it tastes like a drink, not a supplement.
The water test.
A fibre drink lives or dies in the glass. Every batch was judged on how it reacts with water: how fast it dissolves, and whether it stays dissolved.
The clump problem.
Some ingredients team up, pull moisture from the air and clump, which is why most powders turn to glue. We chose ingredients that do not, so the last scoop pours like the first.
Fibre feeds the good bacteria in your gut. Core Biotic adds more of them: 10 strains plus 3 prebiotic fibres. The two work as a pair.
Meet Core BioticFibre without water barely works.
One point came up again and again while we built this: fibre does its job by holding water. Take the fibre without the fluid and you get a fraction of the benefit. That is why Aquafibre is a drink, and why it carries electrolytes alongside the fibre.
Same fibre, double the water.
In a randomised trial of 117 adults on 25g of fibre a day, the group who also drank around 2 litres of water had significantly better results than the fibre-only group. Same fibre. The water made the difference.
Built as a drink on purpose.
Aquafibre mixes 6g of soluble fibre into a full glass of water, with electrolytes in the blend. The fibre and the fluid arrive together, the way the research says they should.
Three fibres. Each earned its place.
We tested form after form of fibre. Three made the cut, and each is there for a different reason.
Acacia fibre.
The gentle one. It dissolves cleanly and is easy on the gut, which is exactly what a daily drink needs.
Guar fibre.
The body of the blend. It gives the drink its substance without turning it into sludge.
Soluble tapioca fibre.
The mixer. It helps everything disappear into water the way a drink should, not a paste.
Six grams of soluble fibre. In a glass you will actually finish.
Everything the test batches taught us, in the finished blend. Orange Citrus, the flavour you voted for.
Asked about the blend.
Why three fibres instead of one?
Each does a different job. Acacia is gentle and dissolves cleanly, guar gives the drink body, and soluble tapioca helps everything mix. One fibre alone could not do all three.
Will it clump like other powders?
That was the whole battle. We avoided ingredient combinations that pull moisture from the air and clump, so the powder stays free-pouring and dissolves fast in water.
What does it taste like?
You decided that. 629 of you ranked the flavours, Orange Citrus won, and Berry and Lemon-Lime were close enough to taste-test too.
Aquafibre feeds your gut bacteria. Core Biotic brings in 10 live strains for that fibre to feed. Better together.
