FOR GUTS THAT REACT TO EVERYTHING
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.

I have tried many supplements over the years. Some I’ve stopped using because I didn’t notice a difference. I Will always aim to keep astaxanthin as part of my stack. I have noticed such an amazing change in my skin. My skin has always been good, but this has taken it to another level. I love this product! I particularly love the Biosphere brand as they use olive oil in the capsules, rather than seed oils. Really happy to support this NZ company.
Great product, I have been using it to help my eyes feel more comfortable ( post menopause) , they are definitely less scratchy than they were! I can’t wait to try the magnesium yet, it looks really good.
We both have the best sleep usimg this product. I am about to put in another order.
Lovely flavour and works really well.
I rely on 'Sleep' to help my sleep. Its a vial part of my evening ritual. I notice when I dont take it
Great for dry eyes. Best I've tried
Take this every night for restless legs and sleep . Alternate between the 2 flavours
Very good product but I did have to adapt it. I found taking it just before bed it would give me a hit of energy. So I no take it with dinner or just after around 7 and it gives my body time to process the ashwaganda. I still do have trouble sleeping but I do feel the nights I do sleep it’s a deeper sleep. I am going through a lot of stress and biological changes but I do feel it has helped just not as much as I hoped. The flavour is delicious and the customer service was awesome. I’m going to try the plain magnesium next time as I think ashwagandha not well suited to me
Great product - slept soundly :)
I’m loving this quality magnesium product from BioSphere as it has transformed the quality of my sleep.
I was sceptical but desperate when I started using Gut Support. After the first month, there hadn’t been a huge change, but I decided I was going to give it 2 months. Only a week into the second tub I noticed a definite change, and after not quite 2 months my system is so much calmer and more regular - the best it has been in nearly 6 years.
Nerve pain gone , deep sleeps after taking this . ! I am about to reorder , thanks guys 😍
This has been a game changer for me . It has eased pain and cramping at night . It promotes a feeling if calm and relaxation . I will never stop using this . Please buy it . I promise you won’t be sorry . Carolyn
Just love this product. I am on my third tin. I have been able to halve my blood pressure medication.
Sleep so much better and no more cramps
I won't need to ask for my money back. It works! The quality of my sleep has improved 10 fold.
Helps me stay asleep all night long
Prompt delivery and high quality. Noticed my eyesight not troubling me as much within a week.
It was a tough winter but this Biosphere Immune got us through.
I began taking this product 2 weeks ago to help with my sleep due to RLS and aching muscles due to injuries. Its great. I fall asleep well and sleep longer. I love the lemon lime flavour too!
Great quality astaxanthin and an easy addition to my daily supplement routine. I take it for its antioxidant, skin and general healthy-ageing benefits. Simple, well-dosed and no fuss. Very happy with it.
Awesome product!
Love it
Really like the flavour and taste, it encourages me to use it daily !
My husband and I have both been taking Biosphere Nitric Oxide, and we’ve been really happy with how we feel since starting it. We both feel so much better overall and have noticed a real difference in our general well-being and energy. It’s now become part of our daily routine, and based on our personal experience, we’re very pleased with it. It’s not often that we find a product that we both feel has made a noticeable difference, but this one has. We’ll definitely continue taking it!
Another one bites the dust! I’m really benefiting from taking this product every evening. I’m sleeping through the night, and waking refreshed. I would recommend this to anyone as a fuss free, easily digestible form of magnesium for settling your nervous system and allowing good sleep patterns.
Really like the Biosphere Magnesium. It's so helpful before and after hard physical work when I tend to get plagued with cramp. Alongside other salts & good hydration it's been great .Also very pleasant to drink. My wife also likes to use it at night for restless legs & to help relax. 😊
I love this product. I noticed an improvement in my skin. Looks and feels so much smoother.
I have systemic health issues and this is great for sleep, nerves and digestion (in a slow moving system). Great combination of types of magnesium. Easy to mix and take.
Great product. I take it every morning 🙂
Having parkinsons disease, exercise is very much my medication but has consequences the magnesium helps with the cramps and sleep quality which makes tomorrow better.
Love this product, after my first month I have far more mobility, energy and stamina, will be purchasing more...
I haven't gotten my very first bottle yet, but I will be ordering more. Capsules are easy to swallow, and makes it easy that need to take with food . Easy to remember with breakfast
It’s one of those things that you don’t you don’t know what you’ve got ‘til it’s gone! I was sleeping well and didn’t notice my gym recovery was good until I ran out of magnesium! Without it, my sleep is terrible and I’m sore for days after working out. Ordering more now!
On my second month of astaxanthin, not much change except a little more energy generally. Will give it a full three months.
I am so happy with my Astaxanthin . Can’t believe that it has worked so quick at pain relief . I have tried lots of other products in many years and I think this is the best thing I have tried . I have no pain and it so good . I hope this keeps up I have arthritis and and a few joint replacements so always in pain . Thank you
Awesome flavour magnesium for a massive day in the mountains!!!
Both flavours are nice and the powder mixes well. No longer getting night time cramps, so very happy with this. Will definitely be continuing with this product.
Awesome product.
Straight answers
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.
