6 reasons this prebiotic works when other fibres backfire
If fibre and probiotics have left you bloated, urgent, or worse, the problem isn't fibre. It's the type. Here's what makes this one different for a sensitive gut.

01
It's certified low FODMAP
by the people who
invented FODMAP.
Most "gentle" gut products just say gentle. This one carries the Monash University Low FODMAP Certified™ mark. Monash are the researchers who created the FODMAP system the entire low-FODMAP diet is built on.
That's an independent lab testing the finished product, not a marketing word on a tub. If you're following low FODMAP, or your gut reacts to the high-FODMAP fibres in most gut supplements, this is the line between a fibre you can take every day and one that leaves you doubled over.
02
It regulates in both directions: loose or backed up.
This is the part most fibres get wrong. Bulking fibres only push one way. Sunfiber® is a soluble fibre studied in clinical trials for both loose stools and constipation, and in people with IBS.
It doesn't force your gut to one extreme. It moves it toward normal. On the days you're loose and urgent, it firms and slows. On the days you're backed up, it softens. One fibre, both problems.
03
It ferments slowly. That's
why it doesn't gas you out.
Here's why a prebiotic made you worse last time: most prebiotic fibres ferment fast. Fast fermentation produces gas fast. On a reactive gut, that's instant bloating and cramping, and it's why you quit within a week.
Sunfiber® is partially hydrolysed guar gum. It ferments slowly and steadily along the gut, feeding your good bacteria without the gas spike. Same prebiotic payoff. None of the blow-up that put you off fibre in the first place.
04
7 grams. The dose the
research actually used.
A lot of gut powders add a token sprinkle of fibre so they can print it on the label, then bulk the tub with cheap filler. The clinical work on this fibre used meaningful daily doses, not a dusting.
Every scoop of Gut Support delivers a full 7g therapeutic dose of Sunfiber®, with no filler padding it out. You're getting the amount that does the work, not the amount that makes the ingredient list look busy.
05
Elderberry polyphenols feed
the bacteria you want more of.
There's a second active most prebiotics don't have: 500mg of Black Elderberry extract. Its polyphenols have been linked in research to higher levels of Akkermansia, a keystone gut bacterium tied to a healthier gut lining and better metabolic health.
And because most of your immune system lives in your gut, feeding the right bacteria supports your everyday immune defences too. It's not just fibre. It's fibre plus the polyphenols that help the good bacteria thrive.
06
Probiotics didn't work because the bacteria don't stick. This feeds the ones that do.
Here's why the probiotics were a waste of money: most swallowed strains just pass through. A lot of the dose doesn't survive stomach acid, and the few that make it rarely settle in and stay. You get a week of feeling slightly better, then you're back buying the next bottle.
Sunfiber works the other way around. It's a prebiotic: instead of adding new bacteria, it feeds the beneficial ones already living in your gut, the strains adapted to you, so they multiply and hold. You're not renting bacteria that move out. You're growing your own.

Two actives. No proprietary blend hiding the doses.
Everything is disclosed, at the dose that matters. Here's exactly what you're taking.
A slow-fermenting soluble prebiotic fibre that regulates in both directions, studied in clinical trials for constipation, loose stools and IBS. It feeds Bifidobacteria without the gas of harsher fibres, slows post-meal blood sugar, and increases satiety to support healthy weight management. Certified low FODMAP by Monash University.
A concentrated source of polyphenols that support the gut lining and the immune tissue around it. Research links black elderberry to higher levels of Akkermansia, a beneficial keystone gut bacterium, supporting both gut health and your everyday immune defences.

Any last questions?
Is it actually certified low FODMAP, or just marketed that way?
Actually certified. It carries the Monash University Low FODMAP Certified™ mark. The finished product is independently tested and certified by Monash, the university that developed the FODMAP system. It's the only product in our range with that certification.
I've reacted badly to other prebiotic fibres. Why would this be different?
Because the reaction usually comes from fast-fermenting, high-FODMAP fibres that flood your gut with gas. Sunfiber® is partially hydrolysed guar gum. It ferments slowly and is certified low FODMAP, which is exactly the combination that avoids the bloating and cramping. It's built for the gut that other fibres upset.
Will it help if I'm loose one day and constipated the next?
That's exactly what it's for. Sunfiber® is bidirectional. It's been studied for both loose stools and constipation. It firms when you're loose and softens when you're backed up, regulating your gut toward normal rather than pushing it one way.
Does it fit a low FODMAP diet or elimination phase?
Yes. The Monash Low FODMAP certification means it's suitable to use during low-FODMAP eating. As always, if you're working through a structured elimination and reintroduction plan with a dietitian, run it past them so it fits your specific protocol.
How long until I notice a difference?
It's a daily fibre, not a laxative, so it builds up rather than hitting overnight. Most people feel the difference within two to four weeks of taking it every day. Consistency is what makes it work.
What's it sweetened with?
Monk fruit extract: natural and low FODMAP. No sugar alcohols (no erythritol, sorbitol or xylitol), which are common triggers for the exact bloating you're trying to avoid. Natural elderberry flavour, and it mixes clear.
Give your gut a fibre it can actually handle.
A full 7g therapeutic dose of Sunfiber®, plus Black Elderberry. Low FODMAP certified, nothing to react to.
