Everyone's right,
you do need
more fibre.
Most fibre powders ferment fast and leave you bloated. This one ferments slowly, feeding the bacteria that keep your gut working.
7g therapeutic dose
Monash Low FODMAP Certified™
Third-party tested
GMP-certified facility
Ten grams short, seven closed in one glass.
Most people are about 10g of fibre short, every day.
Fibre is finally getting the attention protein has hogged for a decade, and the numbers behind the noise hold up. NZ guidance sits around 25g a day for women and 30g for men. Most people land closer to 15g.
That missing 10g is where the benefits live: regularity, steadier blood sugar after meals, appetite that stops nagging, and a better-fed gut microbiome. One scoop of Gut Support carries a full 7g therapeutic dose of soluble fibre.
One scoop closes most of your daily gap.
Slow fermentation: the prebiotic payoff without the gas spike.
The bloating comes from how fast fibre ferments.
Read past the trend's headlines and every dietitian gives the same warning: increase fibre quickly, especially the fast-fermenting kinds in most gut powders, and the fermentation outruns your gut. Gas builds fast, bloating follows, and people quit inside a week convinced fibre "doesn't agree with them".
The problem was never fibre. It's the speed of fermentation. Sunfiber® is partially hydrolysed guar gum, a soluble fibre that ferments slowly and steadily along the gut, feeding your good bacteria at a pace a sensitive gut can keep up with.
And because gentleness is a claim anyone can print, ours is certified: Monash University created the low-FODMAP system, and this formula carries their certification.
Same fibre payoff. None of the blow-up.
Nothing in here for a sensitive gut to react to.
Built for the people fibre has burned before.
If a "gut-friendly" powder has left you bloated, urgent or worse, you're the reader this formula was chosen for. Sunfiber® has been studied in clinical trials for constipation, for loose stools, and in people with IBS. It regulates toward normal, not toward one extreme.
The sweetener follows the same logic: monk fruit, with no sugar alcohols, the quiet trigger hiding in most "gut-friendly" powders.
Gentle was the whole point of choosing this fibre.
What to expect
A daily fibre, not a laxative. It builds.
Honest timelines keep customers. Here's the pattern our reviewers describe.
Days 1–7
It slots into the morning
One scoop in water, mixes clear. Your gut adjusts quietly; no gas spike to push through.
Weeks 2–3
The rhythm shows up
Bathroom visits get more regular and more predictable, in whichever direction yours needed.
Week 4 onward
You stop thinking about it
Daily fibre intake sits where the guidance says it should, without renegotiating every meal.
Made in a GMP-certified facility, every batch third-party tested.
Most fibre powders are
formulated to a price
point. Not to a result.
That's why so many add a token sprinkle of fibre, pad the tub with cheap filler, and leave you feeling nothing, or worse, bloated.
We do it the other way around: the full 7g therapeutic dose the research actually used, real Black Elderberry extract alongside it, and nothing padding the tub.
You're paying for the dose that closes the gap.

Before you start
How quickly will I notice results?
It's a daily fibre, not a laxative, so it builds rather than hitting overnight. Most people feel the difference within two to four weeks of taking it every day. Consistency is the whole game.
Can I take it alongside my medications or other supplements?
Soluble fibre is food-based and widely used daily. As with any supplement, if you take prescription medication or manage a health condition, run it past your GP or pharmacist first; taking fibre a couple of hours away from medication doses is a common-sense habit they may suggest.
How much fibre do I actually need?
NZ guidance sits around 25g a day for women and 30g for men, and most people land closer to 15g. That shortfall is the gap this closes.
Can't I just eat more vegetables and wholegrains?
You should, and food comes first. This is a top-up, not a replacement: one scoop adds 7g without another plate of food, which is the piece most people can't consistently close through meals alone.
Fibre has bloated me before. Why would this be different?
That reaction comes from fast-fermenting fibres flooding the gut with gas. Sunfiber® ferments slowly, and the formula is certified low FODMAP by Monash University, the researchers who created the FODMAP system. It's built for the gut other fibres upset.
What's it sweetened with?
Monk fruit extract, which is low FODMAP, with no sugar alcohols (no erythritol, sorbitol or xylitol), a common trigger for the exact bloating you're avoiding.
Skip the bloat. Get your gut back on track.
A full 7g therapeutic dose of slow-fermenting fibre, plus Black Elderberry. Certified gentle enough for a gut that reacts to everything else.
